Get StartedPrecautions
It is important that your doctor check your progress at regular visits. This will allow your doctor to check for any unwanted effects.
If your symptoms do not improve within a few weeks (or months for onychomycosis), or if they become worse, check with your doctor.
Liver problems may be more likely to occur if you drink alcoholic beverages while you are taking this medicine. Therefore, you should not drink alcoholic beverages while you are taking this medicine.
It is important that you check with your doctor immediately if you persistently experience any discomforts of liver disease (e.g., nausea or vomiting, lack or loss of appetite, general feeling of tiredness or weakness, stomach pain, yellow eyes or skin, dark urine, or pale stools).
