Side
Effects
Nausea, stomach upset, trouble sleeping, headache, or cold symptoms may occur.
If these persist or worsen, notify your doctor promptly. Unlikely but report
promptly: dizziness, mental/mood changes, fast heartbeat, fever. Tell your
doctor immediately if any of these highly unlikely but very serious side effects
occur: fainting, irregular heartbeat. Although drowsiness is very uncommon
at usual doses under normal circumstances, be aware that drowsiness may occur
and may effect the ability to perfom tasks requiring alertness (e.g., driving).
If you notice other effects not listed above, contact your doctor or pharmacist.
