The usual adult dosage is 1 tablet three times a day given orally or as prescribed by the physician. It can be taken with or without food. The dosage may be increased or decreased properly depending on age and symptoms of the patient.
If the patient missed a dose, just take the subsequent doses at the recommended time or schedule. Do not double the dose unless recommended by the physician.
If the patient has taken more than the recommended dosage, consult a doctor.
