Duact capsules treat allergic rhinitis using two active ingredients: acrivastine, a fast-acting antihistamine, and pseudoephedrine, which reduces swelling in the mucous membranes.
For adults and children over 12 years, take 1 capsule as needed.
The capsules should be taken by mouth.
Do not take more than 3 capsules per day. The treatment duration is recommended to be limited to about 10 days.
