Chlorphenamine 4mg Tablets

Chlorphenamine 4mg is a fast-acting, first-generation alkylamine antihistamine clinically indicated for the systemic symptomatic relief of allergic conditions.

Frequently Asked Questions

Chlorphenamine tablets are used to provide rapid relief from the symptoms of allergic reactions and hypersensitivity conditions.

Because chlorphenamine is a first-generation antihistamine, drowsiness and sedation are its most common side effects.

Due to these sedative qualities, users should not drive, operate heavy machinery, or consume alcohol while taking this medication.
