What are the possible side effects of biperiden(Akineton)?
If you experience any of the following serious side effects, stop taking biperiden and seek emergency medical attention:
· an allergic reaction (difficulty breathing; closing of your throat; swelling of your lips, tongue, or face; or hives);
· unusual fever;
· fast or irregular heartbeat;
· anxiety, hallucinations, confusion, agitation, hyperactivity, or loss of consciousness;
· a rash; or
· eye pain.
Other, less serious side effects may be more likely to occur. Continue to take biperiden and talk to your doctor if you experience
· a dry mouth;
· large pupils or blurred vision;
· difficulty urinating or constipation;
· nervousness or anxiety;
· upset stomach; or
· decreased sweating.
Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.
