What is clorfeniramina?

Clorfeniramina is an antihistamine that is used to treat symptoms of allergies such as sneezing, runny nose, and itchy eyes, nose, or throat. It works by blocking the action of histamine, which is a substance that is released by the body during an allergic reaction. Clorfeniramina is available in both tablet and liquid form, and it can also be used as an eye drop or nasal spray.

Some common side effects of clorfeniramina include drowsiness, dizziness, dry mouth, and nausea. These side effects usually go away after a few days of use. However, clorfeniramina can also cause more serious side effects, such as confusion, hallucinations, and seizures. These side effects are more likely to occur in older adults and people with certain medical conditions, such as liver or kidney disease.

Clorfeniramina should not be taken with alcohol or with other medications that cause drowsiness. It is also not recommended for use in children under 2 years of age.

If you are experiencing symptoms of allergies, talk to your doctor about whether clorfeniramina is right for you.
