What is Amoxicillin and How Does It Work?

Amoxicillin is a widely prescribed antibiotic medication belonging to the penicillin class. It is used to treat a variety of bacterial infections by inhibiting the growth and reproduction of bacteria. Amoxicillin works by interfering with the cell wall synthesis of susceptible bacteria, ultimately leading to their destruction.

This broad-spectrum antibiotic is effective against many types of bacteria, including:

• Streptococcus pneumoniae
• Haemophilus influenzae
• Escherichia coli
• Neisseria gonorrhoeae
• Certain strains of Staphylococcus aureus

What makes amoxicillin different from other penicillin antibiotics? Amoxicillin has enhanced absorption in the gastrointestinal tract, allowing for better bioavailability and effectiveness when taken orally. This characteristic makes it a preferred choice for many bacterial infections that can be treated outside of hospital settings.

Common Uses of Amoxicillin 500mg

Amoxicillin 500mg is prescribed for various bacterial infections affecting different parts of the body. Some of the most common uses include:

• Respiratory tract infections (bronchitis, pneumonia)
• Ear, nose, and throat infections (sinusitis, tonsillitis)
• Urinary tract infections
• Skin and soft tissue infections
• Dental infections
• Lyme disease (early stages)
• Helicobacter pylori eradication (in combination with other medications)

Is amoxicillin effective against all types of infections? No, amoxicillin is only effective against bacterial infections. It does not work against viral infections such as the common cold or flu. Using antibiotics for viral infections can contribute to antibiotic resistance, a growing global health concern.

Proper Dosage and Administration of Amoxicillin 500mg

The correct dosage of amoxicillin 500mg can vary depending on the type and severity of the infection, as well as the patient’s age, weight, and overall health condition. Always follow your healthcare provider’s instructions or the guidance on the prescription label.

Typical dosage guidelines for adults with common infections include:

• 500mg every 8 hours (three times daily)
• 875mg every 12 hours (twice daily)

How should you take amoxicillin 500mg? Amoxicillin can be taken with or without food. If you experience stomach upset, taking it with food may help alleviate this side effect. It’s important to space the doses evenly throughout the day to maintain consistent levels of the antibiotic in your system.

What if you miss a dose? If you forget to take a dose, take it as soon as you remember. However, if it’s almost time for your next scheduled dose, skip the missed dose and continue with your regular schedule. Do not double up on doses to make up for a missed one.

Duration of Treatment

The duration of amoxicillin treatment typically ranges from 7 to 14 days, depending on the infection being treated. It’s crucial to complete the entire course of antibiotics as prescribed, even if you start feeling better before finishing the medication. Stopping the antibiotic prematurely can lead to a recurrence of the infection and contribute to antibiotic resistance.

Potential Side Effects of Amoxicillin 500mg

While amoxicillin is generally well-tolerated, like all medications, it can cause side effects in some individuals. Common side effects of amoxicillin 500mg include:

• Nausea and vomiting
• Diarrhea
• Stomach pain or discomfort
• Headache
• Rash
• Yeast infections (oral thrush or vaginal yeast infections)

Most of these side effects are mild and resolve on their own. However, if they persist or worsen, it’s important to consult your healthcare provider.

Can amoxicillin cause serious allergic reactions? Yes, in rare cases, amoxicillin can cause severe allergic reactions, including anaphylaxis. Seek immediate medical attention if you experience symptoms such as difficulty breathing, swelling of the face or throat, or severe skin reactions.

Antibiotic-Associated Diarrhea

One notable side effect of amoxicillin and other antibiotics is antibiotic-associated diarrhea. This occurs when the antibiotic disrupts the normal balance of bacteria in the gut. In some cases, this can lead to an overgrowth of Clostridioides difficile (C. difficile), causing a condition known as C. difficile-associated diarrhea (CDAD).

How can you reduce the risk of antibiotic-associated diarrhea? Some studies suggest that taking probiotics during and after antibiotic treatment may help reduce the risk of antibiotic-associated diarrhea. However, always consult with your healthcare provider before starting any new supplements while on medication.

Precautions and Contraindications for Amoxicillin 500mg

While amoxicillin is generally safe for most people, there are certain situations where it may not be appropriate or may require special precautions:

• Allergy to penicillins or cephalosporins
• History of antibiotic-associated colitis
• Kidney disease
• Phenylketonuria (PKU) – some liquid formulations contain aspartame
• Pregnancy and breastfeeding (consult with a healthcare provider)

It’s crucial to inform your healthcare provider about all medications, supplements, and herbal products you are taking, as amoxicillin can interact with certain substances.

Does amoxicillin interact with birth control pills? Some antibiotics may reduce the effectiveness of hormonal contraceptives. While amoxicillin is not typically associated with this interaction, it’s always best to use additional contraceptive methods during antibiotic treatment and for at least one week after completing the course.

Amoxicillin and Antibiotic Resistance

Antibiotic resistance is a growing global health concern, and the misuse or overuse of antibiotics like amoxicillin contributes to this problem. When bacteria are repeatedly exposed to antibiotics, they can develop mechanisms to survive the antibiotic’s effects, making the medication less effective over time.

How can you help prevent antibiotic resistance?

• Only take antibiotics when prescribed by a healthcare professional
• Complete the full course of antibiotics as prescribed
• Do not share antibiotics with others or use leftover antibiotics
• Practice good hygiene to prevent the spread of infections
• Get vaccinated against preventable diseases

What is the impact of antibiotic resistance on public health? Antibiotic resistance can lead to longer hospital stays, higher medical costs, and increased mortality. It also makes it more challenging to treat common infections and can complicate medical procedures that rely on antibiotics for infection prevention.

Alternatives to Amoxicillin 500mg

In cases where amoxicillin is not suitable or effective, alternative antibiotics may be prescribed. Some common alternatives include:

• Azithromycin
• Clarithromycin
• Doxycycline
• Cephalexin
• Ciprofloxacin

The choice of alternative antibiotic depends on various factors, including the type of infection, the patient’s medical history, and local patterns of antibiotic resistance.

Are there any natural alternatives to antibiotics? While some natural remedies may have antimicrobial properties, they are not substitutes for prescribed antibiotics in treating bacterial infections. Always consult with a healthcare provider before considering alternative treatments.

Monitoring and Follow-up During Amoxicillin Treatment

When taking amoxicillin 500mg, it’s important to monitor your condition and be aware of any changes or new symptoms. Contact your healthcare provider if:

• Your symptoms worsen or do not improve after a few days of treatment
• You experience severe or persistent side effects
• You develop signs of an allergic reaction
• You have concerns about your treatment or medication

How long does it typically take for amoxicillin to start working? Many patients begin to feel better within a few days of starting amoxicillin treatment. However, it’s crucial to complete the entire course of antibiotics as prescribed, even if you feel better, to ensure the infection is fully eradicated and to reduce the risk of antibiotic resistance.

Long-term Effects and Considerations

While amoxicillin is generally safe for short-term use, repeated or long-term use of antibiotics can have potential consequences:

• Disruption of the gut microbiome
• Increased risk of antibiotic-resistant infections
• Potential impact on immune system function

These considerations underscore the importance of using antibiotics judiciously and only when necessary. Your healthcare provider will weigh the benefits and risks of antibiotic treatment based on your individual circumstances.

Can probiotics help restore gut health after antibiotic use? Some studies suggest that taking probiotics during and after antibiotic treatment may help restore the balance of gut bacteria. However, more research is needed to determine the most effective probiotic strains and timing for this purpose. Always consult with your healthcare provider before starting any new supplements.

Storage and Handling of Amoxicillin 500mg

Proper storage and handling of amoxicillin are essential to maintain its effectiveness and safety. Follow these guidelines:

• Store at room temperature, away from heat and moisture
• Keep the medication in its original container
• Keep out of reach of children and pets
• Do not use after the expiration date
• Dispose of unused or expired medication properly

How should you dispose of unused antibiotics? Many pharmacies offer medication take-back programs. Alternatively, you can mix the medication with an undesirable substance (like used coffee grounds), seal it in a plastic bag, and dispose of it in the trash. Do not flush antibiotics down the toilet or sink, as this can contribute to environmental antibiotic resistance.

Liquid Amoxicillin Considerations

If you’re using liquid amoxicillin:

• Shake the bottle well before each use
• Use a measuring spoon or syringe to ensure accurate dosing
• Refrigerate if instructed, but do not freeze
• Discard any unused liquid after 14 days or as directed by your pharmacist

Can liquid amoxicillin stain teeth? Yes, liquid amoxicillin can sometimes cause temporary staining of the teeth. This staining is typically not permanent and can be removed with regular brushing. If you’re concerned about tooth staining, discuss alternative formulations with your healthcare provider.

The Future of Antibiotic Treatment

As antibiotic resistance continues to be a global health concern, researchers are exploring new approaches to combat bacterial infections:

• Development of new antibiotics
• Combination therapies
• Bacteriophage therapy
• Immunomodulation strategies
• Nanotechnology-based treatments

What role will amoxicillin play in future antibiotic treatments? While amoxicillin remains an important antibiotic, its effectiveness may be impacted by increasing resistance. Future treatments may involve more targeted approaches, personalized medicine, and alternative strategies to combat bacterial infections while minimizing the risk of resistance.

The ongoing research in this field highlights the importance of responsible antibiotic use and the need for continued innovation in treating bacterial infections. As we move forward, a multifaceted approach involving new treatments, improved diagnostics, and public health measures will be crucial in addressing the challenges posed by antibiotic-resistant bacteria.

Amoxicillin: antibiotic to treat bacterial infections

1. About amoxicillin

Amoxicillin is a penicillin antibiotic. It is used to treat bacterial infections, such as chest infections (including pneumonia) and dental abscesses. It can also be used together with other antibiotics and medicines to treat stomach ulcers.

It’s often prescribed for children, to treat ear infections and chest infections.

Amoxicillin is only available on prescription. It comes as capsules or as a liquid that you swallow. It’s also given by injection, but this is usually only done in hospital.

2. Key facts

• For most infections, you’ll start to feel better in a few days.
• The most common side effects of amoxicillin are feeling sick (nausea) and diarrhoea.
• Liquid amoxicillin can stain your teeth. This does not last and is removed by brushing.
• You can drink alcohol while taking amoxicillin.
• Sometimes, taking amoxicillin can cause thrush.

3. Who can and cannot take amoxicillin

Amoxicillin can be taken by most adults and children.

Find out more about giving amoxicillin to children on the Medicines for Children website.

Amoxicillin is not suitable for everyone. To make sure amoxicillin is safe for you, tell your doctor if you:

• have ever had an allergic reaction to amoxicillin or penicillin or any other medicine
• have liver or kidney problems
• have recently had, or are due to have, any vaccinations

4. How and when to take amoxicillin

Dosage

The usual dose of amoxicillin capsules is 250mg to 500mg, taken 3 times a day. The dose may be lower for children.

Amoxicillin liquid is available in 125mg and 250mg doses.

Important

Carry on taking this medicine until you’ve completed the course, even if you feel better. If you stop your treatment early, the infection could come back.

How to take it

Try to space the doses evenly throughout the day. If you take it 3 times a day, this could be first thing in the morning, mid-afternoon and at bedtime.

You can take amoxicillin before or after food.

Swallow amoxicillin capsules whole with a drink of water. Do not chew or break them.

Amoxicillin is available as a liquid for children and people who find it difficult to swallow capsules.

If you or your child are taking liquid amoxicillin, it will usually be made up for you by your pharmacist. The medicine will come with a plastic syringe or spoon to help you measure out the right dose. If you do not have one, ask your pharmacist for one. Do not use a kitchen teaspoon as it will not measure the right amount.

If you forget to take it

If you forget to take a dose, take it as soon as you remember, unless it’s nearly time for your next dose. In this case, just leave out the missed dose and take your next dose at the usual time.

Never take 2 doses at the same time. Never take an extra dose to make up for a forgotten one.

If you forget doses often, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to remember your medicines.

If you take too much

Taking an extra dose of amoxicillin is unlikely to harm you or your child, but speak to your pharmacist or doctor if you’re worried.

Urgent advice: Contact 111 for advice now if:

You have taken more than your prescribed dose of amoxicillin and have symptoms including:

• stomach pain or you’re being sick
• blood in your pee
• difficulty peeing or producing less pee than usual

Go to 111.nhs.uk or call 111

5. Side effects

Like all medicines, amoxicillin can cause side effects, although not everyone gets them.

Common side effects

These common side effects happen in around 1 in 10 people. Keep taking the medicine, but talk to your doctor or pharmacist if these side effects bother you or do not go away:

• feeling sick (nausea)
• diarrhoea

Serious side effects

Serious side effects are rare and happen in less than 1 in 1,000 people.

Call a doctor or call 111 now if you get:

• diarrhoea (possibly with stomach cramps) that contains blood or mucus or severe diarrhoea that lasts for more than 4 days
• pale poo and dark pee, and the whites of your eyes or your skin turn yellow (although this may be less obvious on brown or black skin) – these can be signs of liver or gallbladder problems
• bruising or changes in your skin colour
• joint or muscle pain that comes on after 2 days of taking the medicine
• a skin rash with circular red patches (this may be less obvious on brown or black skin)

Some of these serious side effects can happen up to 2 months after finishing the amoxicillin.

Serious allergic reaction

Around 1 in 15 people have an allergic reaction to amoxicillin.

In most cases, the allergic reaction is mild and can take the form of a skin rash.

Mild skin rashes can usually be treated by taking antihistamines.

In rare cases, amoxicillin can cause a serious allergic reaction (anaphylaxis).

Immediate action required: Call 999 now if:

• your lips, mouth, throat or tongue suddenly become swollen
• you’re breathing very fast or struggling to breathe (you may become very wheezy or feel like you’re choking or gasping for air)
• your throat feels tight or you’re struggling to swallow
• your skin, tongue or lips turn blue, grey or pale (if you have black or brown skin, this may be easier to see on the palms of your hands or soles of your feet)
• you suddenly become very confused, drowsy or dizzy
• someone faints and cannot be woken up
• a child is limp, floppy or not responding like they normally do (their head may fall to the side, backwards or forwards, or they may find it difficult to lift their head or focus on your face)

You or the person who’s unwell may also have a rash that’s swollen, raised, itchy, blistered or peeling.

These can be signs of a serious allergic reaction and may need immediate treatment in hospital.

These are not all the side effects of amoxicillin. For a full list, see the leaflet inside your medicines packet.

Information:

You can report any suspected side effect using the Yellow Card safety scheme.

Visit Yellow Card for further information.

6. How to cope with side effects of amoxicillin

What to do about:

• feeling sick – stick to simple meals and do not eat rich or spicy food. It might help to take your amoxicillin after a meal or snack.
• diarrhoea – drink plenty of fluids, such as water or squash, to avoid dehydration. Signs of dehydration include peeing less than usual or having dark, strong-smelling pee. Do not take any other medicines to treat diarrhoea without speaking to a pharmacist or doctor. If you take contraception and you have severe diarrhoea for more than 24 hours, your contraceptive pills may not protect you from pregnancy. Check the pill packet to find out what to do.

7. Pregnancy and breastfeeding

Amoxicillin and pregnancy

It is safe to take amoxicillin during pregnancy.

Amoxicillin and breastfeeding

It is OK to take amoxicillin while breastfeeding. Information shows that only tiny amounts of amoxicillin get into breast milk. Such levels would not be expected to cause side effects in your baby.

Talk to your doctor, pharmacist, health visitor or midwife if:

• your baby is not feeding as well as usual
• they have sickness or diarrhoea
• your baby has oral thrush, or a skin rash
• you have any other concerns about your baby

For more information about how amoxicillin can affect you and your baby during pregnancy, visit the Best Use of Medicines in Pregnancy (BUMPS) website.

8. Cautions with other medicines

There are some medicines that do not mix well with amoxicillin.

Tell your doctor if you’re taking any of these medicines before you start taking amoxicillin:

• methotrexate, used to treat arthritis and psoriasis
• warfarin, a medicine to prevent blood clots
• gout medicines called probenecid or allopurinol
• other antibiotics

Tell your doctor if you’ve recently had, or are due to have, an oral typhoid vaccine. Amoxicillin can make it less effective.

Mixing amoxicillin with herbal remedies and supplements

There is little information about taking herbal remedies and supplements alongside amoxicillin.

Important:
Medicine safety

Tell your doctor or pharmacist if you’re taking any other medicines, including herbal medicines, vitamins or supplements.

9. Common questions about amoxicillin

How does amoxicillin work?

Amoxicillin is a penicillin antibiotic. It works by killing the bacteria that cause the infection.

When will I feel better?

For most infections, you should feel better within a few days.

It’s very important that you keep taking amoxicillin until your course is finished. Do this even if you feel better. It will help stop the infection coming back.

What if I do not get better?

Tell your doctor if you do not start feeling better after taking amoxicillin for 3 days. Also tell them if, at any time, you start to feel worse.

Will it give me thrush?

Some people get a fungal infection called thrush after taking a course of antibiotics like amoxicillin. If you think you have thrush, speak to your pharmacist or ask your doctor for advice.

How does amoxicillin compare with other antibiotics?

Amoxicillin and other penicillins, like phenoxymethylpenicillin, are antibiotics that are widely used to treat a variety of infections, including skin, dental, throat and chest infections.

Not all antibiotics are suitable for every infection. Your doctor will choose an antibiotic that’s suitable for the type of infection you have. Speak to your pharmacist or doctor if you have any questions.

Will it affect my contraception?

Amoxicillin does not stop contraceptive pills working, including the combined pill or emergency contraception.

However, if amoxicillin makes you sick (vomit) or have severe diarrhoea for more than 24 hours, your contraceptive pills may not protect you from pregnancy. Check the pill packet to find out what to do.

Find about more about what to do if you’re on the pill and you’re being sick or have diarrhoea.

Will it affect my fertility?

There’s no evidence to suggest that taking amoxicillin reduces fertility in either men or women.

Does it stain teeth?

If you or your child take amoxicillin as a liquid medicine, it can stain your teeth. This does not last and should go after brushing your teeth well.

Amoxicillin capsules do not stain teeth.

Can I drive or ride a bike?

Yes. Amoxicillin should not affect you being able to drive or cycle.

Is there any food or drink I need to avoid?

You can eat and drink normally while taking amoxicillin.

Can I drink alcohol with it?

Yes, you can drink alcohol with amoxicillin.

Tick-borne borreliosis (Lyme disease) – symptoms, diagnosis and treatment

Infectious pathology proceeds according to a standard algorithm, which includes 3 stages, corresponding to the characteristics of pathogenesis. Stages I and II are conventionally combined into the early phase of infection, and stage III represents the late phase of the disease. Each of the stages of Lyme borreliosis has a special symptom complex. In a separate category, a latent form is distinguished, in which there are no clinical signs, but the pathogen is in the body.

Stage I

At the initial stage, a person experiences signs of general intoxication: fever, chills, headaches and body aches occur. Less common are sore throat, dry cough and runny nose. Intense muscle pain and stiffness of the neck muscles are possible. The symptoms are similar to the flu and other respiratory infections.

The pathognomonic sign of borreliosis is erythema migrans annulare (ME), which manifests itself at the site of a tick bite. First, a red spot appears, which increases in size within a few days. Its edges remain bright red and slightly swollen, and the center turns pale, which is why the redness looks like a ring. The condition is accompanied by an increase in the lymph nodes, which are located near the bite. ME has a diameter of up to 20 cm, in rare cases it reaches a size of 50-60 cm. Redness is most often located on the legs, in the axillary and inguinal regions. If there have been several tick bites, a corresponding number of annular elements may occur. Erythema persists for 2-3 weeks, after which it disappears through the stage of residual pigmentation and desquamation.

In 30% of patients, the symptoms of tick-borne borreliosis are not accompanied by the appearance of ME. In this case, a small inflamed area is formed at the site of suction of the parasite. Occasionally, the disease is accompanied by benign lymphoplasia of the skin, which is also called lymphocytoma. It is manifested by painful bluish-red nodes, which are mainly localized on the face, around the mammary glands, in the genital area. Reactive lymphoproliferation persists for several months and resolves spontaneously.

The duration of stage I is 3-30 days. With the timely start of treatment, it is possible to completely remove the symptoms and eliminate negative long-term consequences. If therapy has not been carried out, the disease passes to stage II of development.

Stage II

Symptoms of the second stage of the disease occur in 10-15% of patients. This stage proceeds with the involvement of 3 body systems: nervous, cardiovascular, osteoarticular. In typical cases, borreliosis is manifested by the pathology of one of the 3 above-mentioned systems, but occasionally combined pathologies develop.

When the nervous system is involved in the process, the following symptoms of borreliosis occur:

1. Meningitis and meningoencephalitis. Infectious damage to the brain is manifested by severe headaches, repeated vomiting, increased susceptibility to bright light and loud sounds. Characterized by soreness of the occipital muscles, pain when moving the eyes. About a third of patients complain of drowsiness during the day and constant insomnia at night, memory impairment, emotional instability.
2. Neuritis of the cranial nerves. Most often, with Lyme borreliosis, the facial nerves are affected, which is accompanied by numbness of half of the face, drooping of the corner of the mouth, and speech disorders. Less often, the oculomotor, abducens, and optic nerves are involved in the process, which leads to complex disorders in the work of the visual analyzer.
3. Bannwart’s meningoradiculoneuritis. This is a disease specific to tick-borne borreliosis, in which the patient has a combination of signs of meningitis, damage to the cranial nerves and roots extending from the spinal cord. In addition to typical meningeal signs, intense pain in the neck and chest, paresis and paralysis of skeletal muscles, impaired coordination of movements and the ability to maintain balance develop.

Cardiovascular pathologies are registered in 10% of patients after 5-6 weeks from the onset of the infectious symptom complex. They are represented by pain in the left side of the chest, increased heart rate, a feeling of fading and interruptions in the work of the heart. Shortness of breath and dizziness caused by circulatory failure are also observed. In severe cases, pericarditis, myocarditis, dilated cardiomyopathy are possible.

Lyme disease typically involves the musculoskeletal system. Lyme arthritis occurs with damage to the large joints of the body as arthralgia, recurrent benign or chronic arthritis. These forms can pass into each other or appear in isolation. A feature of arthritis is inflammation of one or two large joints, in contrast to rheumatoid diseases, which primarily affect small joints and are characterized by symmetrical inflammation. The differential signs of Lyme arthritis include the same intensity of pain and stiffness, which does not depend on the time of day and the patient’s physical activity. Symptoms have an undulating course with periods of exacerbation lasting from several days to several weeks.

More rare symptoms include:

• red rash on palms;
• blistering eruption;
• benign skin lymphocytoma;
• myositis;
• generalized lymphadenopathy;
• hepatitis;
• jade;
• bronchitis;
• orchitis in men.
