Chlorpheniramine is an antihistamine medication used as an active ingredient in many different non-prescription products (such as Chlor-Trimeton
®) and prescription drugs (such as
Tussionex®). It is used to treat
allergies, hives, and the
common cold. There are a few different basic strengths of chlorpheniramine, including:
- Chlorpheniramine 4 mg tablets (immediate-release)
- Chlorpheniramine 8 mg or 12 mg extended-release capsules or tablets
- Chlorpheniramine 8 mg per 5 mL liquid
- Chlorpheniramine 2 mg per 5 mL liquid.
There are different dosing guidelines for chlorpheniramine, depending on the particular product. Typically, adults who are taking immediate-release chlorpheniramine 4 mg tablets take one tablet every four to six hours. For various extended-release products, the typical adult dosage is 8 to 12 mg every 8 to 12 hours. In general, dosing for children is determined by either age or weight.
