Adverse drug reactions include nausea, stomach upset, diarrhea, mild headache, and rash. Contraindications include hypersensitivity to the product and patients with active peptic ulcers, use with caution in people with a history of peptic ulcers, pregnant women, and lactating women.

Contraindications include hypersensitivity to the product, use with caution in pregnant and lactating women. Rash, nausea, stomach upset, lack of appetite, abdominal pain, diarrhea and other adverse reactions may occur after use.
