Nausea, vomiting, loss of appetite, stomach ache, diarrhea, or darkening of the skin/nails may occur. Nausea and vomiting can be severe. In some cases, drug therapy may be necessary to prevent or relieve nausea and vomiting. Changes in diet such as eating several small meals or limiting activity may help lessen some of these effects. If these effects persist or worsen, notify your doctor or pharmacist promptly.
