Nov 20, 2023

A brief overview of Chlorpheniramine Maleate

Chlorpheniramine maleate is a common antihistamine used to treat allergy symptoms. Here's an overview.

  1. Mechanism: Chlorpheniramine Malate blocks the effects of the histamine released by the body when an allergic reaction occurs. Histamine causes various allergy symptoms, such as sneezing and itching. It can also cause a runny or watery nose.
  2. Common uses: It's primarily used for allergic conditions such as hay fever, allergic conjunctivitis, and hives. You can also use it to relieve symptoms of a common cold such as runny eyes and nose.
  3. Forms: Chlorpheniramine maleate is available in a variety of forms including tablets, capsules, and syrups. It can also be found as an ingredient in some combinations of cold and allergy medication.
  4. Dosage: The recommended dose varies based on the age of the patient and the product. Follow the directions on the label of the medication or those given by your healthcare provider.
  5. Side effects: Drowsiness, dizziness, blurred vision, and dry mouth are common side effects. Many people experience a sedative reaction to it, which is why taking it at nighttime is often recommended.
  6. Precautions: People should use caution when taking Chlorpheniramine Maleate if they are required to be alert. It can cause drowsiness. Avoid alcohol and other drugs that can cause drowsiness while using these medications. Consult a medical professional if you have certain medical conditions, or are taking specific medications.
  7. Duration: The action of chlorpheniramine maleate is usually shorter than that of some of the newer antihistamines. This means that it may be necessary to take more often throughout the day.
  8. Availability: In many countries, it is available without prescription to treat mild allergy symptoms. However, prescription-strength versions may also be available for severe allergic reactions.
  9. Consultation: Before using Chlorpheniramine Malate, it is important to speak with your healthcare provider or pharmacist. This is especially true if you are suffering from a medical condition or taking any other medication.

  2. Common uses: It's used to treat allergies, such as seasonal allergies (hay fever or allergic rhinitis), persistent allergies (year-round allergies), and allergic skin disorders like hives. Cetirizine can also be used to relieve the symptoms of allergic conjunctivitis, or eye allergies.
  3. Forms: Cetirizine hydrochloride comes in many forms including tablets, chewable tablets, oral solutions, and as an ingredient of combination cold and allergy medication.
  4. Dosage: The recommended dose varies depending on the age of the patient, the product, and the severity of the symptoms. Follow the instructions on the label of the medication or those given by your healthcare provider.
  5. Side effects: Cetirizine, in general, is not considered sedating. This means that it is less likely than older antihistamines to cause drowsiness. Some individuals may experience mild drowsiness, or fatigue when taking higher doses.
  6. Warnings: Although it is less likely than other antihistamines to cause drowsiness, people should be cautious when performing activities that require alertness such as driving a car or operating heavy equipment until they are familiar with how the medication will affect them. Consult your healthcare provider if you have certain medical conditions, or are taking certain medications.
  7. Duration: Cetirizine is a more potent antihistamine than older antihistamines. It can provide relief for up to 24 hours after a single dose.
  8. Availability: Cetirizine hydrochloride can be purchased over-the-counter (OTC) by many countries. This makes it available without a prescription to treat mild-to-moderate allergy symptoms. Prescription-strength versions may also be available for severe allergic reactions.
  9. Consultation: Before using Cetirizine Hydrochloride it is best to consult a physician or pharmacist, particularly if you are suffering from any medical conditions or taking other medications.

Background Information

Background information about antihistamines will help you understand Chlorpheniramine Maleate (Cetirizine Hydrochloride) and Chlorpheniramine Maleate:

Histamine, Allergies and:

  • Histamine, a naturally occurring chemical, is involved in many physiological processes. It regulates stomach acid, neurotransmission and immune responses.
  • Histamine is a key component in the treatment of allergies. Histamine is released by mast cells and basophils when the body encounters allergens (substances such as pollen, dust mites or certain foods that trigger an allergic response).
  • Histamine can cause a variety of allergy symptoms such as sneezing and runny nasal passages, watery eyes, hives, and congestion. These symptoms are the body's way of trying to eliminate the allergen.

Antihistamines:

  • Antihistamines are a group of medications that counteract the effects of histamine. They do this by blocking histamine's action on receptors.
  • These medications are used to treat allergy symptoms such as hay fever, year-round allergies, and allergic skin conditions.
  • Antihistamines are also effective in treating symptoms of non-allergic conditions such as the common cold. They can relieve symptoms like sneezing, runny eyes and nose.

Older vs. Newer Antihistamines:

  • Antihistamines are divided into two categories: older first-generation and newer second-generation antihistamines.
  • Chlorpheniramine Maleate and other older antihistamines are well known for their sedative properties, which can lead to drowsiness or impair cognition. These antihistamines are commonly used at night or for sedation.
  • The newer antihistamines like Cetirizine hydrochloride are considered to be non-sedating, or at least less sedating. These are best used during the day as they do not affect alertness or cognitive function.

Antihistamines:

  • Chlorpheniramine Maleate, Cetirizine hydrochloride, or any other antihistamine depends on a number of factors. These include the severity and age of the symptoms, tolerance for sedation, and possible drug interactions.
  • It's important to ask your pharmacist or healthcare provider for personalized advice.

When selecting the best medication to treat an allergy or allergic reaction, it is important that you are informed about the histamine, allergies, and antihistamines.
