The drug is usually administered in a dose of 1 tablet 3-4 times a day with an interval of 4-6 hours between two doses. Children over 12 years of age are dosed at 20-40 mg/kg/day in 3-4 doses. Tablets are taken with food (exceptionally, they can also be given on an empty stomach), always whole and taken with a glass of water or milk. The patient must be provided with a sufficient supply of fluids. The length of treatment is decided by the doctor (do not use for a long time without consultation!). Do not drink alcohol.
