Keflex, also known by its generic name cephalexin, is a widely prescribed antibiotic belonging to the cephalosporin class of drugs. This medication is used to treat a variety of bacterial infections and is available in several forms, including oral capsules, tablets, and liquid suspensions. As a prescription medication, Keflex plays a crucial role in modern healthcare, helping combat various bacterial ailments.

Is Keflex effective against all types of infections. Keflex is specifically designed to target bacterial infections and is not effective against viral infections such as the common cold or flu. It works by interfering with the formation of bacterial cell walls, ultimately leading to the death of the bacteria.

Common Uses of Keflex 500mg

Keflex 500mg is prescribed for a range of bacterial infections affecting different parts of the body. Its versatility makes it a go-to option for many healthcare providers when treating common bacterial ailments.

• Respiratory tract infections
• Otitis media (middle ear infections)
• Skin and skin structure infections
• Bone infections
• Genitourinary (urinary tract) infections

Can Keflex be used preventatively. In some cases, Keflex is prescribed as a preventive measure, particularly for endocarditis (inflammation of the heart valve) caused by bacterial infection. This prophylactic use highlights the drug’s importance in not just treating but also preventing certain serious conditions.

Dosage Guidelines for Keflex

The dosage of Keflex can vary depending on the type and severity of the infection being treated, as well as the patient’s age, weight, and overall health condition. It’s crucial to follow the prescribed dosage regimen to ensure the medication’s effectiveness and minimize the risk of side effects.

Adult Dosage

• For most infections: 250 mg every 6 hours, or 500 mg every 12 hours
• For more severe infections: Up to 4 grams daily in divided doses

Pediatric Dosage

• Typically based on the child’s weight: 25-50 mg/kg/day in divided doses
• For more severe infections: Up to 100 mg/kg/day in divided doses

How long should a course of Keflex last. The duration of treatment usually ranges from 7 to 14 days, depending on the infection being treated. However, it’s essential to complete the entire course of antibiotics as prescribed, even if symptoms improve before the medication is finished.

• Probenecid: May increase Keflex levels in the blood
• Metformin: Keflex may increase the risk of lactic acidosis in patients taking metformin
• Warfarin: Keflex may increase the anticoagulant effect of warfarin

Does Keflex interact with birth control pills. While Keflex is not known to directly interact with oral contraceptives, it’s always advisable to use additional contraception methods during antibiotic treatment, as some antibiotics may reduce the effectiveness of birth control pills.

Proper Storage and Handling of Keflex

To maintain the effectiveness and safety of Keflex, proper storage and handling are essential. Following these guidelines can help ensure that the medication remains potent and safe for use throughout its shelf life.

• Store at room temperature (between 59°F to 86°F or 15°C to 30°C)

• Improved overall feeling of wellness
• Gradual return to normal activities

When to Contact Your Healthcare Provider

• Symptoms worsen or new symptoms appear
• No improvement after several days of treatment

How long does it usually take to see improvement with Keflex. While individual responses can vary, many patients begin to notice improvement within 2-3 days of starting treatment. However, it’s crucial to complete the entire prescribed course of antibiotics, even if you feel better before finishing the medication.

Alternatives to Keflex

While Keflex is an effective antibiotic for many bacterial infections, there may be instances where alternative medications are more appropriate. The choice of antibiotic depends on various factors, including the type of infection, patient allergies, and local antibiotic resistance patterns.

Common Alternatives

• Amoxicillin
• Ciprofloxacin
• Doxycycline
• Azithromycin
• Trimethoprim-sulfamethoxazole

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

In conclusion, Keflex 500mg is a versatile and effective antibiotic used to treat a wide range of bacterial infections. While it offers significant benefits in combating various ailments, it’s crucial to use it responsibly and under medical supervision. By understanding its uses, dosage guidelines, potential side effects, and necessary precautions, patients can maximize the benefits of this medication while minimizing risks.

Are there any other precautions or warnings for this medication?




Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Allergy: Some people who are allergic to penicillin antibiotics also experience allergic reactions to cephalosporins, including cephalexin. Before you take cephalexin, inform your doctor about any previous adverse reactions you have had to medications, especially cephalosporins and penicillins. Contact your doctor at once if you experience signs of an allergic reaction, such as skin rash, itching, difficulty breathing, or swelling of the face and throat.

Antibiotic-associated colitis: This medication, like other antibiotics, may cause a potentially dangerous condition called antibiotic-associated colitis (or pseudomembranous colitis). Symptoms include severe, watery diarrhea that may be bloody. If you notice these symptoms, stop taking cephalexin and contact your doctor as soon as possible.

Bacterial resistance: Misuse of an antibiotic such as cephalexin may lead to the growth of resistant bacteria that will not be killed by the antibiotic. If this happens, the antibiotic may not work for you in the future. Although you may begin to feel better when you first start taking cephalexin, you need to take all of the medication exactly as prescribed by your doctor to finish ridding your body of the infection and to prevent resistant bacteria from taking hold. Do not take cephalexin or other antibiotics to treat a viral infection such as the common cold; antibiotics do not kill viruses, and using them to treat viral infections can lead to the growth of resistant bacteria.

Kidney function: People with severe kidney problems may require a lower dose of cephalexin. People with kidney disease or reduced kidney function should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Liver function: Cephalexin can cause a decrease in liver function, although this happens only occasionally. People with liver disease or reduced liver function should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. If you experience signs of decreasing liver function, such as yellowing of the skin or whites of the eyes, dark urine, or pale stools, contact your doctor as soon as possible.

Overgrowth of organisms: Prolonged or repeated use of cephalexin may result in an overgrowth of bacteria or fungi and organisms that are not killed by the medication. This can cause other infections to develop, such as yeast infections.

Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.

Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking cephalexin, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

• stop taking one of the medications,
• change one of the medications to another,
• change how you are taking one or both of the medications, or
• leave everything as is.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Medications other than those listed above may interact with this medication. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking.

Can I drink alcohol while taking antibiotics? – Pivo.by

Richard Clasco, MD, in The New York Times, answers one of the most popular questions for beer drinkers: is it okay to drink alcohol while taking antibiotics ?

With some antibiotics, definitely not. With most others, however, the answer may be cautious but yes.

Concern about drinking alcohol while taking antibiotics may have its roots in the rubber industry of the 1880s.Around this time, manufacturers began using a chemical known as disulfiram to accelerate the vulcanization of rubber. Soon the workers began to experience a strange reaction: they became seriously ill after drinking alcohol.

In the 1940s, doctors investigated whether disulfiram was useful as a treatment for alcoholism. Patients who took the drug after drinking alcohol experienced nausea, vomiting, sweating, redness, heart palpitations, headaches, and a host of other anxiety symptoms, and many stopped drinking.Today the drug is marketed under the Antabuse brand name.

In the 1960s, the antibiotic metronidazole (brand name Flagyl) was introduced in the United States. While taking it, doctors began to observe problematic symptoms in their patients who drank alcohol. They were so unpleasant that metronidazole itself has been studied as a treatment for alcoholism.

Although metronidazole is not used to combat alcohol abuse, it remains an essential drug in the treatment of various gastrointestinal infections, including diverticulitis, as well as in the treatment of gynecological disorders and sexually transmitted diseases.It is a safe and effective medication, with the caveat that alcohol must be avoided while taking it.

Certain other antibiotics have also been reported to cause reactions with alcohol. Most are cephalosporins, a class of broad-spectrum antibiotics that are used to treat various infections. However, although there are many cephalosporins, only a fraction of them are believed to cause this reaction.

The vast majority of antibiotics do not interact with alcohol.The five most commonly prescribed antibiotics in the United States – amoxicillin (amoxil), azithromycin (zithromax), amoxicillin-clavulanate (augumentin), cephalexin (keflex), and ciprofloxacin (cipro) – do not contain warnings about side effects when taken with alcohol. Likewise, over-the-counter cough and cold medications that contain alcohol do not alert you to the potential consequences of taking them with antibiotics. While there is no research to prove it is safe to consume alcohol while taking these antibiotics, the potential for serious interference seems to be low.

However, it is best to avoid alcohol when fighting an infection, as it can interact with many drugs other than antibiotics and irritate the already inflamed stomach lining. The FDA usually advises patients to warn the doctor that you are or plan to use alcohol.

The most popular fraudulent schemes in Ukraine – Security Agency LLC “Protection-Service”

In the times of innovative technologies, the methods of fraudsters are also being modernized. Mostly scammers use telephone fraud schemes or over the Internet. Therefore, you need to be always on the alert.

What are the most common fraud schemes?

SMS quiz. In such schemes, you will see the following calls: “Send SMS and win money, a phone, an apartment, and so on.The more SMS, the more chances to win ”. At the same time, it is written in small print that the cost of sending a message can reach 50 UAH.

SMS dating . This scam is primarily aimed at men. Tariffication for such numbers is fabulous.

Refund. You receive an SMS stating that your account has been replenished, while immediately a call comes from scammers that they allegedly put money into your account by mistake and a request to return it back.At the same time, the account status on the mobile phone does not change.

Call from the bank. The fraudster introduces himself as a bank employee and says that your card has been blocked. Most often, PrivatBank clients face this. In order to unblock the card you will be asked to give the card number, three-digit code and pin.

A relative was arrested. There is a call from an unknown number to the victim’s landline or mobile phone. The swindler informs that he is a police officer and someone of the “victim’s” family was in trouble – he became the culprit of an accident or other crime, as a result of which he is under arrest.To solve the problem, you need to pay a certain amount. At the same time, the person is constantly kept in suspense, not giving the opportunity to contact a relative and critically assess the situation.

Lost SIM card . Scammers find out the bank card number and contact number of a potential victim when buying from a fake online store. Before that, they make a couple of calls to the person, and then they turn to the cellular salon with a request to restore the lost number. Then the scammers request a PIN code, update passwords in mobile banking and freely make payments from your card.

Advert . If you have lost some thing or pet and placed an ad about the loss, scammers can contact you and demand money for returning the thing that they do not have in sight. Sometimes documents or a phone are stolen deliberately in order to make money on the return.

Online shopping. Criminals are asking for prepayment or full payment for the item. Naturally, you will not receive a purchase, and the phone number is no longer available.

Counterfeit credit card. A person receives an SMS notification or a phone call asking for a bank card with a large credit limit and a low interest rate. When the victim bites, it turns out that a commission must be paid for issuing a card. Since many banks practice charging for issuing cards, this is not suspicious

Computer virus. The user receives a message that the computer is infected with a virus and in order to remove it, a certain fee must be paid.

Letters from foreign businessmen or high officials. A swindler, playing the role of a rich foreigner or a corrupt official, asks for help in conducting transactions on the territory of Ukraine – transfer funds abroad, invest in any enterprises. But before receiving money from a fake rich man, you must deposit a certain amount as a guarantee.

Imitation of work on the Forex market .
