• nervousness, drowsiness, confusion, tachycardia, blurred vision, constipation, dry mouth, nausea and urinary retention

Biperiden may cause serious side effects which may include:

• CNS : Drowsiness, vertigo, headache, and dizziness are frequent. With high doses nervousness, agitation, anxiety, delirium, and confusion are noted. Biperiden may be abused due to a short acting mood-elevating and euphoriant effect. The normal sleep architecture may be altered (REM sleep depression). Biperiden may lower the seizure-threshold. Some instances of dementia have been noted to correlate with chronic administration of anticholinergic medications such as Biperiden for Parkinson's disease.
• Peripheral side effects : Blurred vision, dry mouth, impaired sweating, abdominal discomfort, and obstipation are frequent. Tachycardia may be noted. Allergic skin reactions may occur. Parenteral use may cause orthostatic hypotension.
• Eyes : Biperiden causes mydriasis with or without photophobia. It may precipitate narrow angle glaucoma.

What special precautions should I follow?

• Biperiden has not been associated with serum enzyme elevations during treatment and must be a very rare cause of clinically apparent acute liver injury, if it occurs at all.
• Isolated instances of mental confusion, euphoria, agitation and disturbed behavior have been reported in susceptible patients.
• Caution should be observed in patients with manifest glaucoma, though no prohibitive rise in intraocular pressure has been noted following either oral or parenteral administration.
• Patients with prostatism, epilepsy or cardiac arrhythmia should be given this drug with caution.
• Occasionally, drowsiness may occur, and patients who drive a car or operate any other potentially dangerous machinery should be warned of this possibility.
• As with other drugs action on the central nervous system, the consumption of alcohol should be avoided during Akineton therapy.
• It is not known whether biperiden is distributed into milk. Because many drugs are distributed into milk, biperiden should be used with caution in nursing women.

What to do in case of emergency/overdose?

Symptoms of overdosage may include:

• dilated and sluggish pupils, warm, dry skin, facial flushing, decreased secretions of the mouth, pharynx, nose, and bronchi, foul-smelling breath, elevated temperature, tachycardia, cardiac arrhythmias, decreased bowel sounds, urinary retention, delirium, disorientation, anxiety, hallucinations, illusions, confusion, incoherence, agitation, hyperactivity, ataxia, loss of memory, paranoia, combativeness, and seizures.

Management of overdosage:

• In case of overdose, call the poison control helpline of your country. In the United States, call 1-800-222-1222.

• Treat hyperthermia, coma, rhabdomyolysis, and seizures if they occur.
• A small dose of physostigmine can be given to patients with severe toxicity (e.g., hyperthermia, severe delirium, or tachycardia).
• Administer activated charcoal orally if conditions are appropriate. Gastric lavage is not necessary after small to moderate ingestions if activated charcoal can be given promptly.
• Hemodialysis, hemoperfusion, peritoneal dialysis, and repeat-dose charcoal are not effective in removing anticholinergic agents.
