Zuclopenthixol
Clopixol / Clopixol-Acuphase
One medicine, different preparations. Know which one is in your treatment plan.
Draft for review · Clinical content has not been revalidated for this website.
Not FDA approved. This guide uses UK information; doses and schedules depend on the exact preparation.
What it is used for
Zuclopenthixol treats schizophrenia and other psychoses. It may help reduce voices, suspicious thoughts, and severe distress.
Tablets and long-acting depot support ongoing treatment. Acuphase is a short-term injection for an acute episode, including mania.
How it works
It blocks some dopamine signaling. That can reduce psychotic symptoms, but can also cause movement or hormone effects.
The target diagram cannot predict your response. Different preparations release the medicine over different lengths of time.
What to expect over time
TABLETS
Benefit can begin early, but fuller improvement may take several weeks.
ACUPHASE
A short-term injection acting over days, not a long-term depot schedule.
DEPOT
Releases medicine over weeks. Keep injection appointments and report side effects early.
Taking your medication
Take tablets with water, with or without food. Follow your own dose and timing; do not add extra tablets.
A clinician gives injections. Ask which preparation you receive and when the next dose is due.
Avoid alcohol. Do not drive with blurred vision or until you know how alert and steady you feel.
When to get help
Emergency help: collapse, seizure, severe breathing/swallowing trouble, or fever with stiff muscles and confusion.
Emergency help: chest pain with breathlessness, stroke symptoms, or an erection lasting four hours.
Urgent advice: a swollen painful leg, fainting/palpitations, new spasms, or mouth movements, fever/sore throat, jaundice, or severe constipation.
Early side effects
Sleepiness, dizziness, dry mouth, constipation, blurry vision, or restlessness can occur. Stand up slowly and report falls or swallowing problems.
Other effects to discuss
Tell your team about stiffness, tremor, weight gain, milk production, changed periods, or sexual problems. Some abnormal movements can persist.
What to keep track of
Expect checks of movement, weight, blood pressure, and blood tests, with heart checks when needed. Tell your team if you feel overly sleepy or cannot sit still. Depot effects can last after the last injection.
Before you start
Mention heart rhythm or clot problems, fainting, low body salts, seizures, liver/kidney disease, breathing problems, diabetes, glaucoma, urinary difficulty, low blood counts, and pregnancy or nursing. Older adults with dementia have extra risks; this medicine is not licensed for dementia-related behavior problems.
Medicines & interactions
Heart medicines and other antipsychotics
Some combinations increase dangerous rhythm risks. Have every new medicine checked, including antibiotics.
Alcohol, sleep aids, and opioids
These can add sleepiness, falls or breathing problems. Do not combine without a specific safe plan.
Lithium and other prescriptions
Lithium can add serious toxicity. Review antidepressants, blood thinners, blood-pressure drugs, and Parkinson medicines.
Remedies and procedures
Some allergy, bladder, and nausea medicines worsen side effects. Tell your dental, surgery, and anesthesia teams what you take.
Everyday tips
Keep a record of the exact injection name, date, dose, and next appointment. Call the clinic if you may miss it.
Track symptoms and daily activities that matter to you. Tell your team when taking treatment is difficult.
Avoid overheating and protect your skin from sun. Ask for a hot-weather plan.
Report new swallowing difficulty, repeated choking, or a major change in alertness without waiting for routine follow-up.
Your questions, answered
What if I miss tablets or an injection?
For a missed tablet, the UK leaflet says take the next dose at the usual time; do not double. Call the clinic about a missed injection.
Can I stop if I feel better?
Plan changes with your prescriber. Tablets usually need gradual reduction. A depot already given continues to release medicine.
What about pregnancy or nursing?
Discuss treatment and feeding with your team. Leaflets and prescribing information differ on breastfeeding; get an individual plan.
What if I receive too much?
Seek urgent medical or poison-center advice immediately, even if you feel well. Call emergency services for collapse, seizure, or breathing trouble.
Storage & safety
Keep medicine away from children and follow the pack's storage instructions. Keep 2 mg tablets in their original container and injection ampoules in their outer carton to protect from light. Ask the pharmacy about disposal; never share medicine.
