Side effects of long-term use of chlorpheniramine

At present, we don't advocate long-term medication for allergic rhinitis, said the director and chief physician of the Department of Otolaryngology, Jinhua Central Hospital. Especially in the treatment of chronic allergic rhinitis, we do not advocate long-term medication, but advocate local medication, that is, local treatment. Taking chlorpheniramine for a long time has side effects.

The adverse reactions of chlorpheniramine include drowsiness, dizziness, headache, dry mouth, nausea, vomiting, hypotension, etc., which can easily excite the central nervous system and induce epilepsy. Long-term application can cause granulocytopenia. Therefore, it is forbidden for epileptic patients, infants and lactating women, and is very useful for patients with pyloric obstruction, prostatic hypertrophy, bladder neck obstruction, narrow-angle glaucoma, hyperthyroidism and hypertension.
