Indications: For allergic reactions, nasal allergies, hives and itching.
Table Notes:
- AGE LIMIT: For allergies, don't use under 1 year of age (Reason: it's a sedative). For colds, not recommended at any age (Reason: no proven benefits) and should be avoided if under 4 years old. Avoid multi-ingredient products in children under 6 years of age (Reason: FDA recommendations 10/2008).
- DOSAGE: Determine by finding child's weight in the top row of the dosage table
- ADULT DOSAGE: 4 mg. Repeat every 6-8 hours as needed
- 6-12 years LONG-ACTING (L.A.) DOSAGE: 8 mg long-acting (LA) tablet every 12 hours as needed
- 12 years and older LONG-ACTING (L.A.) DOSAGE: 12 mg long-acting (LA) tablet every 12 hours as needed
- Brompheniramine dosage is the same as chlorpheniramine dosage.
- MEASURING the DOSAGE: Syringes and droppers are more accurate than teaspoons. If possible, use the syringe or dropper that comes with the medication. If you use a teaspoon, it should be a measuring spoon. Regular spoons are not reliable. Also, remember that 1 level teaspoon equals 5 ml and that ½ teaspoon equals 2.5 ml.
