Gastrointestinal symptoms may include nausea, heartburn, dry mouth, abdominal pain, decreased appetite, vomiting, diarrhea, constipation, and inflammation in the mouth, so patients should report any unusual symptoms.

Rare symptoms of rapid heartbeat may occur, and respiratory symptoms such as shortness of breath or nasal congestion may also arise. Blood tests may show decreased platelet counts or increased white blood cell counts, so any unusual symptoms should be reported immediately. In females, rare occurrences of breast enlargement, menstrual irregularities, or chest pain may appear.
