Artane (Trihexyphenidyl) – Patient Information (UK)

Artane is the brand name of trihexyphenidyl, a medicine used to treat certain movement disorders. It works by reducing excessive nerve signalling in the brain. This page explains what Artane is for, how it works, how to take it safely, and what to watch for.

What is Artane?

Artane (trihexyphenidyl) is an anticholinergic medicine. It helps to relieve symptoms caused by imbalance between two chemical messengers (acetylcholine and dopamine) involved in movement control.

In the UK, trihexyphenidyl is commonly supplied as tablets. It may be used in adults and, in some circumstances, in children for specific movement disorders, but the dose must be individualised.

How Artane works (mechanism of action)

Artane blocks the action of acetylcholine (a “cholinergic” signal) in the brain. In some movement disorders—such as Parkinson’s disease or drug-induced parkinsonism—signals may become imbalanced, leading to tremor, stiffness, or muscle spasms. By reducing cholinergic activity, trihexyphenidyl can help restore balance and improve symptoms.

Important: It does not increase dopamine directly. Instead, it reduces the cholinergic influence that can contribute to movement symptoms.

What it’s used for in the UK (indications)

Artane is typically used for:

• Parkinson’s disease symptoms, particularly tremor and stiffness.
• Drug-induced movement disorders, such as:
  • Acute dystonia (painful muscle spasms, often affecting the neck, jaw, eyes, or tongue).
  • Drug-induced parkinsonism (similar symptoms to Parkinson’s disease caused by certain medicines).
  • Other extrapyramidal symptoms where anticholinergic treatment is appropriate.
• Other specific movement problems in selected patients, as advised by a clinician.

Whether Artane is suitable depends on your symptoms, your other medicines, and your health history.

Pharmacokinetics (how your body handles Artane)

After taking a tablet, trihexyphenidyl is absorbed and then distributed throughout the body. The medicine is metabolised mainly in the liver. The metabolites and unchanged drug are eliminated via urine and bile/faeces (depending on individual metabolism and other factors).

Time course:

• Onset of benefit may be seen within hours to days, but full effect—especially in Parkinson’s symptoms—often requires careful dose adjustment over time.
• Half-life may vary between individuals; therefore, dosing schedules are designed to maintain symptom control across the day.

Your clinician may adjust the dose based on how well it works and the side effects you experience.

How to take Artane: timing and dosing

Dosage must be tailored to the individual. The following information is provided to help you understand typical approaches; always follow your own instructions on your medicine label or treatment plan.

Typical starting approach

• Start low to reduce side effects.
• Increase gradually every few days (or as advised) until symptoms improve.

Typical adult dosing patterns (general guidance)

Common regimens vary by the condition being treated. For example:

• Parkinson’s disease: often started at a low dose, then increased slowly; the total daily dose may be divided into multiple doses across the day.
• Drug-induced dystonia/parkinsonism: may require quicker symptom relief; dosing can be different from long-term Parkinson’s regimens.

Common dosing schedule concept:

• Many people take it two to three times daily depending on symptom control and side effects.
• Tablet strength and the prescribed dose determine exactly how often you take it.

How to manage missed doses

If you miss a dose:

• Take it as soon as you remember unless it’s close to the time of your next dose.
• Do not take a double dose to make up for the missed one.
• If you’re unsure, ask your pharmacist or clinician for advice.

Taking Artane with or without food

Food-related advice is important for comfort and side effect control (see “Food interactions” below). In practice:

• Some people find taking it with meals reduces stomach discomfort.
• Follow your own guidance about whether to take it with food.

Food interactions and lifestyle tips

Trihexyphenidyl can cause side effects typical of anticholinergic medicines—especially dry mouth and constipation. While there aren’t many “must avoid” food interactions, diet and hydration can make a big difference.

Hydration

• Drink water regularly, particularly if you notice dry mouth.
• Consider sugar-free drinks or oral gels if dryness is troublesome.

Constipation prevention

• Maintain fibre in your diet (fruit, vegetables, whole grains) where appropriate.
• Stay physically active if safe for you.
• If constipation develops, discuss options early with a pharmacist.

Gastrointestinal comfort

• If you get nausea or indigestion, taking doses with food may help.
• A sudden change in diet may not be needed, but consistent hydration is helpful.

Alcohol and medicine interactions

Artane can cause tiredness, drowsiness, and blurred vision in some people. Alcohol can intensify these effects.

Alcohol

• Avoid or limit alcohol if you feel sleepy or light-headed.
• Do not drive or operate machinery if alcohol plus Artane affects your alertness.

Other medicines that may interact

Trihexyphenidyl has anticholinergic effects. Using it with other medicines that also have anticholinergic properties can increase the risk of side effects such as dry mouth, constipation, blurred vision, urinary retention, and confusion.

• Other anticholinergic/antimuscarinic medicines (including some medicines for overactive bladder, some allergies, and some sleep-related medicines)
• Antihistamines that cause drowsiness or have anticholinergic activity
• Medicines that affect mood or cognition where confusion risk is present

There are also medicines that can interact indirectly by affecting heart rhythm or sedation. Always tell your pharmacist about all medicines you take, including over-the-counter products.

Always check: if you start a new medicine (including cold/flu products), ask whether it has anticholinergic or sedating ingredients.

Safety profile: common side effects and what to do

Like all medicines, Artane can cause side effects. Many are related to anticholinergic action.

Common side effects

• Dry mouth
• Blurred vision
• Constipation
• Difficulty urinating (or reduced urine flow)
• Drowsiness, fatigue, or dizziness
• Nausea
• Confusion (more likely in older adults or those with cognitive impairment)
• Decreased sweating, which may increase overheating risk

Less common but important side effects

• Severe constipation or bowel blockage
• Acute urinary retention (inability to pass urine)
• Worsening of glaucoma (especially narrow-angle glaucoma)
• Irregular heartbeat or significant dizziness/fainting (seek urgent advice)

When to seek urgent help

Get medical help urgently if you experience:

• Severe agitation, confusion, hallucinations, or inability to stay awake
• Severe abdominal pain, vomiting, or signs of intestinal obstruction
• Inability to urinate or significant pain when trying to pass urine
• Eye pain, redness, or sudden blurred vision

Who should be cautious (contraindications and precautions)

Artane may not be suitable for everyone. Extra caution is needed if you have:

• Glaucoma (especially narrow-angle glaucoma)
• Urinary retention or conditions like an enlarged prostate
• Severe constipation or bowel motility problems
• Myasthenia gravis
• Significant cognitive impairment or confusion (older adults may be at higher risk)
• Heart rhythm problems or other serious cardiovascular conditions
• Heat sensitivity or inability to sweat (risk of overheating)

Inform a healthcare professional if you have any of the above, or if you develop new symptoms after starting treatment.

Practical tips for safe use

Start low and monitor

• Because side effects can occur when starting, clinicians usually increase the dose gradually.
• Keep track of symptom improvement and side effects (for example: dryness, constipation, sleepiness, dizziness).

Protect your vision

• If you notice blurred vision, avoid driving until it settles.
• Make sure your eye problems are checked, especially if you have risk factors for glaucoma.

Prevent constipation early

• Don’t wait for constipation to become severe—improve fluids, fibre, and activity early.
• Ask a pharmacist about suitable stool softeners or laxatives if needed.

Urinary problems

• If you have difficulty passing urine, stop and seek advice promptly rather than “pushing through”.

Heat and exercise

• Trihexyphenidyl may reduce sweating. In hot weather, take precautions to prevent overheating.
• Use shade, hydration, and rest as needed.

Driving and machinery

• Be cautious if you feel drowsy or have blurred vision.
• If alcohol is also involved, your reaction time may be more affected.

Alternative options

Depending on the specific condition and your medical history, other treatments may be considered. These can include:

• For Parkinson’s disease: other medicines such as levodopa-based therapies, dopamine agonists, MAO-B inhibitors, or COMT inhibitors (chosen based on stage of disease and individual needs).
• For drug-induced dystonia/parkinsonism: adjustments to the triggering medicine where possible, and sometimes other medication strategies.
• Non-medicinal approaches: physiotherapy, occupational therapy, and movement strategies may support overall function.

Your clinician can help you weigh benefits and risks of alternatives, including the likelihood of cognitive or bowel/urinary side effects.

UK market and legal context (brief overview)
