Drug Class: Anticholinergic / Antiparkinsonian Agent | Form: Oral Tablet | Prescription Status: Prescription Only (Rx) — DRAP Registered
What is Kempro 5mg Tablet? Kempro 5mg contains Procyclidine Hydrochloride — an anticholinergic medicine used to manage symptoms of Parkinson's disease and movement disorders caused by antipsychotic medicines. It works by blocking excess acetylcholine activity in the brain — restoring the balance between acetylcholine and dopamine that is disrupted in Parkinson's disease. Procyclidine is particularly effective for tremor and muscle rigidity. It is used alone or alongside other antiparkinsonian medicines under strict neurological supervision and requires careful dose adjustment, especially in elderly patients.
What is Kempro 5mg Used For?
- Parkinson's disease — tremor, rigidity, and slowness of movement (پارکنسن کی بیماری — کپکپاہٹ اور اکڑن)
- Drug-induced parkinsonism — movement side effects caused by antipsychotic medicines (دواؤں سے ہونے والی اکڑن)
- Acute dystonia — sudden painful involuntary muscle contractions (اچانک پٹھوں کا کھنچاؤ)
- Drug-induced akathisia — restlessness and inability to stay still (بے چینی اور بے قراری)
- Muscle spasms associated with neurological conditions (اعصابی بیماریوں میں پٹھوں کی اکڑن)
How Does it Work? In Parkinson's disease, dopamine levels fall while acetylcholine activity becomes relatively excessive — causing tremor and rigidity. Procyclidine selectively blocks muscarinic acetylcholine receptors in the brain, reducing this excess cholinergic activity and restoring better neurotransmitter balance. This results in reduced tremor, less muscle rigidity, and improved voluntary movement control. It does not replace lost dopamine but corrects the imbalance that worsens motor symptoms.

Who Should NOT Take Kempro 5mg?
- Allergy to Procyclidine or any anticholinergic medicine
- Closed-angle glaucoma — Procyclidine raises eye pressure dangerously
- Enlarged prostate causing urinary retention (پیشاب رکنا)
- Gastrointestinal obstruction or severe constipation
- Myasthenia gravis
- Severe liver or kidney impairment
- Tardive dyskinesia — anticholinergics can worsen this condition
- Pregnancy and breastfeeding
- Children unless specifically directed by specialist
Side Effects
Common: Dry mouth (منہ کا خشک ہونا), blurred vision, constipation (قبض), difficulty urinating, mild dizziness, increased heart rate, mild confusion — particularly in elderly patients.
Serious — Stop and seek emergency help immediately: Acute urinary retention — complete inability to urinate (پیشاب بالکل بند ہو جانا — فوری مدد لیں), acute glaucoma — sudden severe eye pain with vision loss (آنکھ میں شدید درد — فوری ہسپتال جائیں), severe confusion or hallucinations especially in elderly (وہم اور خیالی باتیں), high fever with hot dry skin indicating anticholinergic toxicity, rapid or irregular heartbeat, severe agitation.
Drug Interactions
| Medicine | Interaction |
|---|---|
| Other anticholinergic medicines | Additive anticholinergic toxicity — dry mouth, confusion, urinary retention worsen significantly |
| Antipsychotics (Haloperidol, Chlorpromazine) | Procyclidine reduces antipsychotic blood levels — monitor psychiatric condition closely |
| Antidepressants (TCAs) | Increased anticholinergic side effects — confusion and urinary retention risk |
| Antihistamines | Additive anticholinergic and sedative effects |
| Levodopa | Procyclidine may reduce Levodopa absorption — take doses apart |
| Alcohol (شراب) | Increases CNS depression and confusion — avoid completely |
| Metoclopramide | Directly opposing actions — avoid combination |
Storage: Store below 25°C in a cool, dry place. Protect from moisture and direct sunlight. Keep out of reach of children (بچوں کی پہنچ سے دور رکھیں). Do not use after expiry date.
FAQs
Q: Can Kempro 5mg be stopped suddenly if side effects become bothersome? Never stop suddenly — abrupt discontinuation can cause serious worsening of Parkinson's symptoms and withdrawal effects. Always consult your neurologist for a gradual and supervised dose reduction plan.
Q: Why does Kempro cause dry mouth and blurred vision? These are expected anticholinergic effects — Procyclidine blocks acetylcholine receptors throughout the body, not just in the brain, affecting saliva production and eye focusing muscles. These effects are usually manageable and reduce with time.
Q: Is Kempro safe for elderly patients with Parkinson's disease? Elderly patients are significantly more sensitive to anticholinergic side effects — particularly confusion and urinary retention. Doses must be kept as low as possible and the patient monitored closely by their doctor.
