Short description


Avapena, also known as chloropyramine, is an antihistamine drug widely used to relieve allergy symptoms. It contains the active ingredient chloropyramine, which blocks histamine receptors and thus helps reduce allergic reactions. Avapena medicine is available in various forms including lozenges, making it convenient to use.

Avapena 25 mg para que sirve?

Avapena is used to treat various allergic conditions such as hay fever, hives, allergic rhinitis and others. It helps to reduce symptoms such as itching, redness, swelling and sneezing, providing relief to patients.

Avapena pastillas are convenient to use and are suitable for quick relief from allergic reactions. They are particularly popular with those who prefer not to take tablets. The recommended dosage of Avapena is 25 mg, but the exact dosage may vary depending on individual needs and doctor's instructions.

Avapena 25 mg pastillas dosage should be determined based on individual patient characteristics, including age, body weight, medical condition, and specific allergic reaction or disease.

For adults and children over 12 years of age, it is generally recommended to start treatment by taking 1 tablet (25 mg) 3 to 4 times a day. This dosage may be adjusted by your doctor depending on your body's response to treatment and the severity of symptoms.

For young children, the dosage should be strictly individualized and selected by a doctor, taking into account the child's body weight and general condition. As a rule, children are prescribed a reduced dose compared to adults.

Avapena lozenges can be taken independently of meals, but taking them with food may help to reduce the risk of gastrointestinal side effects.

The duration of Avapena should be determined by a physician. In cases of insufficient therapeutic effect or the occurrence of side effects, dose adjustment is possible. Do not independently increase, decrease, or stop taking the drug suddenly without consulting a specialist, even if the symptoms have improved.

Contraindications to the use of Avapena

  • Allergy to chloropyramine or other components of the drug: If the patient has previously experienced allergic reactions to Avapena or its components, the drug should not be used.
  • Angle glaucoma: Avapena medicine may increase intraocular pressure, which is dangerous for patients with angle glaucoma.
  • Urinary tract and prostate problems: The drug may increase urinary problems, especially in the presence of prostatic hyperplasia or other urinary tract problems.
  • Stomach or duodenal ulcer in the acute stage: Avapena may worsen the symptoms of these conditions.
  • Bronchial asthma: Use of the drug may worsen symptoms.
  • Pregnancy and lactation: The use of Avapena tablets during pregnancy and lactation requires caution and should be done only on strict indications under the supervision of a doctor, as the active substance may affect the development of the fetus and penetrate into breast milk.

Side effects of Avapen

Side effects from taking Avapena chloropyramine can range from mild to more serious:

  • Sedation: One of the most common side effects is drowsiness, which may affect the ability to drive or operate machinery.
  • Dry mouth: This is a common side effect associated with the anticholinergic effects of chloropyramine.
  • Dizziness and headache: Some patients may experience dizziness and headaches after taking the drug.
  • GI disorders: Nausea, vomiting, diarrhea, or constipation may also occur as side effects.
  • Visual disturbances: Some patients may experience blurred vision.
  • Weight gain: Prolonged use may contribute to weight gain in individuals.
  • Hypersensitivity reactions: In rare cases, allergic reactions such as rash, urticaria, and Quincke's edema may occur, which require immediate discontinuation of the drug and medical attention.
  • Increased fatigue and general malaise: Patients may experience increased fatigue and a feeling of weakness, which may affect daily activities.
  • Mental effects: In some cases, mental changes such as anxiety, agitation, insomnia or, conversely, central nervous system depression may be observed.
  • Difficulty in urination: This is especially true in patients with previous urinary tract or prostate diseases.

Interaction with other medicines

Avapena, whose active ingredient is chloropyramine, is widely used in medicine to treat allergic reactions due to its antihistamine properties. However, like many other medications, Avapena chloropyramine can interact with other drugs and medications, which can alter their effectiveness or increase the risk of side effects. Understanding these interactions is important for a safe and effective treatment.

Drugs that depress the CNS

Avapena medication may increase the sedative effects of drugs that depress the central nervous system (CNS), such as benzodiazepines, sleeping pills, anticonvulsants, some antidepressants, and alcohol. This enhancement may lead to deeper sedation, increased fatigue, decreased concentration and slower reactions, which is especially dangerous when driving or operating machinery.

Anticholinergic agents

Avapena pastillas have anticholinergic properties and may enhance the effects of other drugs with anticholinergic activity, such as atropine, certain antidepressants (tricyclic antidepressants), antiparkinsonian agents, and antipsychotic drugs. This enhancement may lead to an increased risk of side effects such as dry mouth, constipation, difficulty urinating, blurred vision, and increased intraocular pressure.

Monoamine oxidase inhibitors (MAOIs)

The use of Avapen in combination with monoamine oxidase inhibitors (MAOIs), which are used to treat depression and some other conditions, may lead to a significant increase in blood pressure. Therefore, a time interval of at least 14 days should be observed between taking MAOIs and Avapen.


Alcohol enhances the sedative effect of Avapena chloropyramine, which may lead to a significant decrease in cognitive function and motor skills, increasing the risk of accidents and injuries. Therefore, consumption of alcoholic beverages should be avoided during treatment with Avapena.


The combination of Avapena medicine with other antihistamines may result in an increase in both therapeutic and side effects, which is especially true for sedation and other central neurotoxic effects. Such interactions may require dosage adjustment or modification of the treatment regimen to avoid excessive CNS depression and other adverse reactions.

Cardiovascular System

Avapena 25 mg may interact with drugs affecting the cardiovascular system, such as antihypertensives, altering their effectiveness. This may result in unpredictable changes in blood pressure and heart rate, requiring close monitoring and possible treatment adjustments.

Drugs for the treatment of the gastrointestinal tract

Drugs intended to treat the gastrointestinal tract, especially those that affect GI motility, may interact with Avapena chloropyramine. Avapena's anticholinergic properties may increase the antimotor effects of some of these medications, increasing the risk of constipation and other disorders.

Diabetes medications

Avapena medicine may affect blood glucose levels, making close monitoring of diabetic patients necessary. Interactions with antidiabetic drugs may require adjusting their dosages to prevent hypo- or hyperglycemia.

Thyroid medications

Drugs used to treat thyroid disorders may interact with Avapena pastillas, affecting their efficacy and hormone balance. Patients taking such medications may require regular thyroid monitoring during treatment with Avapena medicine.

Avapena in the United States and what Avapena sounds like in English

In the USA and other English-speaking countries, Avapena may be known by other names, and the active substance chloropyramine is called "Chloropyramine" in English. It is important to clarify the name and dosage of the drug when buying abroad.

Therapeutic effect and half-life

The therapeutic effect of Avapena medicine usually occurs within the first hour after taking it and may last for several hours. The half-life of the lozenges in the body is about 20 hours, which means that the drug is slowly eliminated from the body.

Precio Avapena can vary by country, region, dosage form, and dosage. In Mexico, Avapena is popular, available in pharmacies and can also be purchased online through various online pharmacies. Buying online can offer convenience and possibly better prices, but it is important to make sure that the purchase is made through a trusted supplier and that the drug meets the necessary quality standards.

Avapena (chloropyramine) is an effective antihistamine medication for the treatment of allergic conditions. When used correctly and followed as prescribed, Avapena medicine can significantly improve the quality of life of people suffering from allergies by providing symptom relief. However, it is important to consider potential side effects and interactions with other medications, and to strictly follow medical recommendations.
