Dizziness, nausea, vomiting, trouble sleeping, and headache may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

This medication may cause your urine, sweat or saliva to turn red, brown, or black. This is harmless, but your clothes may become discolored.
