Aleve is one brand of the over-the-counter drug naproxen sodium 220 milligrams (mg). It treats many types of mild pain. You may have taken it to treat your headaches, menstrual cramps, arthritis, muscles aches, toothaches, backaches, and even mild fever. If you take Aleve, though, you may wonder what else it does in your body.

Although Aleve can bring relief, it can also cause side effects. Some of these side effects can happen just from short-term use. Long-term use of Aleve can also cause other side effects. Some people are at greater risk of Aleve side effects because of certain medical conditions that they have.

Here’s what to know about how Aleve works and the side effects it can cause.

Aleve, or naproxen sodium 220 mg, is the over-the-counter version of naproxen sodium 275 mg, which is available by prescription only. Aleve is closely related to naproxen base 250 mg, also prescription only.

Both Aleve and its prescription counterparts belong to a class of medications called nonsteroidal anti-inflammatory drugs (NSAIDs). These drugs reduce pain and fever by preventing your body from making prostaglandins. Prostaglandins are substances your body produces when tissues of your body are injured. These substances contribute to many of the effects of inflammation, including swelling, fever, and pain.

Inhibiting your body’s production of prostaglandins can help prevent pain and other effects related to inflammation. But it can also interfere with some other functions.

Prostaglandins naturally help protect your stomach from damage. When Aleve reduces your prostaglandin production, it can cause:

  • stomach pain
  • constipation
  • diarrhea
  • gas
  • heartburn
  • nausea or vomiting

These effects are more likely the older you are or the longer you use Aleve.

More serious side effects include:

  • swelling
  • bleeding
  • ulcers
  • tears in your stomach, small intestine, or large intestine

These effects can be fatal and can happen without warning. If you notice severe stomach pain or bloody or black, tarry stools while you take Aleve, stop taking the drug and call your doctor right away. To lower your risk of digestive system side effects, use the lowest effective dosage for the shortest time.

Aleve can also increase your blood pressure. You might not notice any signs that your blood pressure is increased. And if you already have high blood pressure, taking Aleve might make it worse. You should talk to your doctor before using Aleve if you have high blood pressure.

Aleve can also reduce your blood’s ability to clot. This can lead to bleeding. Talk to your doctor before using Aleve if you plan on having surgery soon.

Long-term use of Aleve can make your heart work harder. Aleve makes you retain water, which increases the load on your heart. This extra work can cause pressure on your cardiovascular system and can sometimes lead to a heart attack or stroke. These risks are even greater at higher dosages, even if you don’t have any heart conditions or risk of heart disease. Call 911 or local emergency services if you have:

  • chest pain
  • shortness of breath
  • slurred speech
  • weakness in your arms or legs

These are signs of a stroke or heart attack. If you take Aleve and have unexplained weight gain or swelling, especially in your legs and feet, talk to your doctor right away. These may be signs of heart failure. To lower your risk of heart problems, use the lowest dosage for the shortest amount of time.

Prostaglandins maintain the pressure in your kidneys so that these organs can filter the fluids in your body. A decrease in your level of prostaglandins from taking Aleve can cause problems with your kidney function. You may notice fluid retention or changes in how much you urinate. If you notice these changes while taking Aleve, stop taking it and contact your doctor.

People with certain medical conditions may experience more side effects from Aleve than other people. These conditions include:

  • history of stomach ulcers or stomach bleeding
  • kidney disease
  • heart disease
  • liver disease

If you have any of these conditions, talk to your doctor before using Aleve. Your doctor may suggest another medication to avoid complications.

For most people, Aleve is an effective treatment for mild pain and fever, especially for short-term use. Side effects can occur, but for the most part the effects are mild. Typically, more severe side effects are associated with extended use. But, as with any medication, if you have a medical condition, take other drugs, or simply aren’t sure if you should take it, talk to your doctor.

Undesirable drug effects and their causes. Side effects, allergic reactions to the drug, overdose. How to avoid drug side effects?

Everyone who has ever taken a medicine knows that it can not only treat a disease, but also have side effects. And even if the doctor does not warn about the presence of side effects in the drug, then in the leaflet to the drug, a separate line lists all those undesirable effects that may occur during treatment with this drug. What is it, side effect ? And is it possible to do without it?

Chapter 2.5 states that the effect of most drugs is based on their physicochemical or chemical interaction with cell membrane receptors. As a result of this, certain changes occur in all cells that have receptors that “recognize” this drug. Their summation leads to a change in the functions of a tissue, organ or organ system, which is the purpose of the drug, that is, its therapeutic effect. For example, blood pressure decreases, pain subsides, swelling decreases, and so on. But the matter is not limited to the therapeutic effect. A drug with exceptional selectivity is an ideal, a “magic bullet”, precisely aimed at a sore spot and not touching healthy tissues. In real life, the action of most drugs resembles a multi-colored mosaic. This is due to several reasons. First, the administered medicine does not only get to the right place. In the body, it is carried by the blood to all tissues and meets with components of cell membranes ( receptors ) capable of interacting with it. And healthy cells have receptors that can bind to drugs. This leads to a change in their functions, and, therefore, to any pharmacological effect. For example, we lowered the pressure, but diarrhea appeared or the heart rate increased. These effects will no longer be curative, because the patient took this drug for another purpose. Secondly, part of the drug, as we already know from the previous chapters, undergoes transformation under the action of the body’s defense systems ( biotransformation ) and loses its original pharmacological activity, but the resulting substances (metabolites) may have some new biological properties and cause various effects.

Drugs have the main therapeutic effect, which is expected when using the drug in each specific case (for example, analgesics are used to relieve pain, antihypertensive drugs are used to lower blood pressure, and so on). Sometimes there are several such therapeutic effects, and two or three of the most pronounced ones determine both the main pharmacological effect of the drug and the indications for its use.

For example, for preparations containing loratadine as an active substance, the column “pharmacological action” indicates: antiallergic, antipruritic, antiexudative. In sodium bicarbonate , more commonly known as baking soda, the pharmacological action is antacid, expectorant, restoring the alkaline state of the blood – it all depends on the route of administration, dosage form and dose.

Effects that are not directed against the disease, beyond the purpose for which the drug is taken, are called side effects. By definition, side effects drugs are undesirable effects that are part of the spectrum of pharmacological activity of the drug and occur when the drug is used in therapeutic doses (not in cases of overdose).

Side effects can occur with all medications. Their frequency reaches 10-20%. Ask the doctor who prescribed this drug for possible side effects of the medicine.

Lacking sufficient selectivity, drugs affect the functions of many tissues and organs (including those not affected by the disease). Some negative effects of the medicinal product that do not go beyond the resistance zone in terms of intensity or duration of exposure, the body can “neutralize on its own”. In other cases, when the state of the organism as a system has gone beyond the stability zone, a side effect of the drug appears.

Side effects may be primary or secondary. The primary effect occurs as a direct consequence of the influence of this drug on the substrate, for example, when the substance irritates the gastric mucosa, nausea, vomiting, and pain occur. Secondary side effects develop indirectly as a result of taking the drug, for example, hypovitaminosis and dysbacteriosis when the intestinal microflora is suppressed by antibiotics. More on this will be discussed a little later.

For acetylsalicylic acid , which, by the way, refers to over-the-counter drugs, the “Side effect” column in the instructions or in the reference book takes more than one line. “Tinnitus, dizziness, hearing loss, epigastric pain, heartburn, nausea and vomiting, severe bleeding from the gastrointestinal tract, thrombocytopenia, anemia, leukopenia, Reye’s syndrome, hypersensitivity reactions (bronchospasm, laryngeal edema and urticaria), “aspirin” bronchial asthma, interstitial nephritis, acute renal failure … “We will not list all the side effects … ” . However, judge for yourself how balanced the decision to take any drug should be.

Carefully read the instructions for use of the drug, especially the columns “Side effect”, “Contraindications”, “Overdose”, “Precautions”, “Special instructions”.

nausea, headache, etc. ) and disappear after discontinuation or reduction in the dosage of the drug. However, there are those that can be severe and even life-threatening for the patient (liver and kidney damage, significant hematopoietic disorders – aplastic anemia, and others). It is believed that 0.5-5% of patients require hospital treatment for adverse drug reactions.

Before prescribing a drug to a patient, the doctor evaluates the possible risk (columns “Contraindications”, “Side Effects”, “Precautions” in the instructions or manuals) and makes sure that the drug will not harm the patient’s health.

oral ) is first exposed to the gastrointestinal tract. In such cases, side effects may be tooth enamel destruction, stomatitis, gastrointestinal disorders – irritation of the mucous membrane, nausea, a feeling of bloating, loss of appetite, constipation or diarrhea, indigestion, and so on. These reactions usually resolve quickly after discontinuation of the drug. A number of drugs can stimulate the release of hydrochloric acid, slow down the production of protective mucus or the processes of natural renewal of the mucous membrane, which creates the preconditions for the formation of ulcers. This effect is called ulcerogenic (from English ulcer – ulcer), hormones of the adrenal cortex from the group of corticosteroids ( glucocorticoids ), analgesics, drugs with pronounced anti-inflammatory activity and exerting, in addition , analgesic and antipyretic action ( non-steroidal anti-inflammatory drugs ), reserpine , tetracycline , caffeine and others.

Relatively often the liver and kidneys are affected by medication. Why? The liver is a barrier between the intestinal vessels and the general circulatory system. When taken orally, all drugs pass through the liver before entering the general circulation. It is she who takes the first blow and it is in her that most drugs accumulate and undergo biotransformation. Moreover, the longer the drug is retained in the liver, the higher the likelihood of a violation of its functions and structure. Liver complications often occur with the use of halogen-containing drugs ( chlorpromazine , chloral hydrate , halothane and others), preparations of arsenic, mercury, some antibiotics ( tetracycline , streptomycin ) and so on.

The kidneys are the excretory organ. Through them, many medicinal substances are excreted from the body – unchanged or after a series of transformations. The accumulation of these substances in the kidneys is a prerequisite for the manifestation of a toxic effect on this organ ( nephrotoxicity ). Antibiotics streptomycin , gentamicin , neomycin and other representatives of aminoglycosides, butadione , sulfanilamide preparations 9 have this effect 0135, vasoconstrictors and others.

The side effect of drugs can be manifested in the violation of some functions of the nervous system. Nerve cells are particularly sensitive to chemicals, so drugs that cross the barrier that separates the central nervous system from the blood (called hematoencephalic ), may cause headache, dizziness, lethargy, and impaired performance. Long-term use of certain drugs is dangerous with more serious complications. Thus, drugs that have an inhibitory effect on the central nervous system ( neuroleptics ) can cause the development of depression and parkinsonism, and drugs that reduce the feeling of fear and tension ( tranquilizers , or anxiolytics ) – disrupt gait, stimulants – cause prolonged insomnia, and so on. The aminoglycoside antibiotics mentioned above ( streptomycin , gentamicin , neomycin and others) sometimes affect hearing and the vestibular apparatus.

The advent of broad-spectrum antibiotics has also given rise to a number of complications associated with their use. First, antibiotics cause the death and decay of the microbes that caused the disease, which increases the flow of toxins into the blood – poisons produced by these microbes. This sharply exacerbates all the symptoms of the disease and requires additional therapy to neutralize toxins. Secondly, antibiotics do not always make out who is an enemy and who is a friend, and together with pathogens they infect microorganisms that are “friendly” to a person, which make up his natural microflora. As a result, the ratio and composition of microorganisms coexisting in the gastrointestinal tract changes ( dysbacteriosis ). The protection of the body is sharply weakened, and under these conditions, previously “dormant” microbes, whose activity was suppressed by the natural microflora, can begin to multiply. The most common is candidiasis (it is caused by a fungus of the genus Candida). It affects the mucous membranes and skin, which have lost their natural protection. To prevent this complication, antibiotics are combined with antifungal agents. Against the background of dysbacteriosis, more serious additional infections can occur, which most often affect the respiratory tract and especially the digestive organs.

One of the most dangerous complications from the use of drugs is the suppression of hematopoiesis – anemia (in most forms of which there is a decrease in the number of erythrocytes – red blood cells) or leukopenia (a decrease in the number of leukocytes – white blood cells th bodies). Some antibiotics (e.g. chloramphenicol ), nonsteroidal anti-inflammatory drugs ( indomethacin , phenylbutazone and others), anti-tuberculosis drugs and others. The destruction of blood cells is sometimes due to allergic reactions, the cause of which may be the use of, for example, methyldopa , Analgin , quinidine and others.

A common complication of drug therapy is hypersensitivity reactions to the drug ( allergic reactions ). A medicine is a substance alien to the body ( antigen ), therefore, at the first contact with it or its complex with a protein, blood proteins ( antibodies ) can be formed, which protect the body from the “stranger”. With subsequent administration, such an antigen drug interacts with antibodies, and an allergic reaction develops, which can manifest itself as a skin rash, itching, swelling, and other, sometimes more dangerous, symptoms. The strongest allergenic substances ( allergens ), among the drugs are penicillin antibiotics , sulfanilamide drugs , local anesthetics ( local anesthetics ), prophylactic or curative drugs, obtained from killed or weakened cultures of microorganisms, their toxins or antigens ( vaccines ), analgesics.

Some drugs may cause photosensitivity in a patient – increased sensitivity of the body to the action of solar (ultraviolet) radiation, usually manifested by inflammation of exposed areas of the skin and mucous membranes. This is manifested by a sensation of itching, burning, swelling and redness of the affected area of ​​the skin. Photosensitizing drugs can cause premature skin aging, as well as eye burns, decreased immunity, allergic reactions, and, in rare cases, skin cancer (melanoma) in susceptible patients. Patients who are forced to take drugs that cause photosensitivity (such information is indicated on the package or in the instructions for the drug), while taking them, should avoid visiting tanning beds, physiotherapy (ultraviolet lamps), exposure to direct sunlight and use sunscreen (glasses, lotions and creams for exposed skin, and so on).

During treatment with drugs that have photosensitizing properties, it is necessary to avoid visits to solariums, physiotherapy procedures (UVI), exposure to direct sunlight. It is advisable to use sunscreen.

therapeutic doses). Doses exceeding therapeutic doses cause toxic effects. Overdose of is a serious problem, especially with drugs where the maximum tolerated dose is not much higher than the therapeutic dose. The risk of overdose is often the reason why doctors prefer one drug over another when the effectiveness of both is close. For example, benzodiazepines ( medazepam , diazepam ) are usually prescribed as sedatives or hypnotics, and not barbiturates . The reason for this is simple – benzodiazepines are safer in case of accidental or intentional overdose. Better safety inherent in new type 9 antidepressants0132 fluoxetine or paroxetine , which are gradually replacing imipramine or amitriptyline .

“Choose the lesser of two evils.” This well-known phrase applies to pharmacology as well. Let’s compare the degree of danger in case of an overdose of amitriptyline and fluoxetine. In the “Overdose” column, amitriptyline lists “hallucinations, convulsions, delirium, coma, cardiac conduction disturbance, extrasystole, ventricular arrhythmias, hypothermia, and others.” With an overdose of fluoxetine, “nausea, vomiting, excitation of the central nervous system, convulsions” occur.

Overdose may be related to the characteristics of the body’s effect on the drug ( pharmacokinetics ) in a particular patient. For example, the accumulation of a drug in toxic concentrations (although a therapeutic dose was taken) is possible as a result of a violation of its biotransformation or delayed excretion. This happens in diseases of the liver and kidneys, especially in old age. Therefore, in such patients, doctors reduce the dose or frequency of taking the medication.

Exact observance of the doctor’s prescriptions and the requirements of the instructions for the use of the drug, taking medications at the appointed time in many cases can avoid complications. However, if side effects still occur, you should immediately consult a doctor for advice.

Your doctor may reduce your dose, change the frequency of your medication, or replace it with a different one. All this will minimize unwanted effects. Of course, the selection of the necessary drug in a safe dosage is carried out by the doctor, but the final decision whether to take the drug or not remains with the patient (chapter 2.1).
