Thorazine
Thorazine
- In our pharmacy, you can buy thorazine without a prescription, with delivery in 5–14 days throughout Canada. Discreet and anonymous packaging is available.
- Thorazine (chlorpromazine) is used for schizophrenia, acute psychosis, severe nausea and vomiting, bipolar mania, preoperative anxiety, persistent hiccups and acute behavioural disturbance. It is a first‑generation (typical) antipsychotic that mainly antagonises dopamine D2 receptors and also blocks serotonin, histamine (H1) and alpha‑adrenergic receptors.
- Usual dosages: adults typically start 25–100 mg orally three times daily with maintenance commonly 200–800 mg/day divided; for nausea 10–25 mg every 4–6 hours; children: weight‑based dosing ~0.5–0.55 mg/kg per dose every 4–6 hours (adjust per physician); elderly start at lower doses (about half) and titrate cautiously. IM doses are commonly 25–50 mg as needed (use product-specific guidance).
- Forms of administration: oral tablets (10, 25, 50, 100, 200 mg), oral solution (commonly 10 mg/mL) and injectable solution for IM/IV (commonly 25 mg/mL).
- Onset time: sedation and control of acute agitation may begin within 15–60 minutes (IM is faster); oral effects often begin within 30–60 minutes; full antipsychotic benefits may require days to weeks of treatment.
- Duration of action: sedative effects typically last several hours (approximately 4–6 hours); pharmacologic effects from a single dose can persist longer and therapeutic antipsychotic effect is maintained with regular dosing (clinical effect and plasma levels can last up to 24–36 hours or longer depending on dose and individual metabolism).
- Alcohol warning: do not consume alcohol while taking thorazine — alcohol and other CNS depressants markedly increase sedation, respiratory depression and risk of hypotension.
- The most common side effect is drowsiness (sedation).

Major National Pharmacy Chains (Shoppers Drug Mart, Rexall, London Drugs)
Many Canadians ask whether chlorpromazine is easy to get at high-street pharmacies.
Shoppers Drug Mart and Rexall usually dispense generic chlorpromazine or imported brands when a matching DIN is present.
London Drugs in the western provinces generally stocks injectables only in select hospital-supply or clinic-focused locations.
Provincial formularies influence local stocking and can limit which strengths are carried on retail shelves.
- Shoppers Drug Mart: Typically stocks generic chlorpromazine tablets in common strengths (10 mg–100 mg) when a DIN is available.
- Rexall: Often dispenses generic chlorpromazine tablets and may source imported brands if a DIN matches the prescription.
- London Drugs (West): More likely to hold injectable ampoules (25 mg/mL) at hospital-supply branches; retail stores may not carry injectables.
Injectables are more commonly held for hospital or clinic use than for regular retail dispensing.
Patients in rural areas may face variable stock levels compared with urban centres.
Online Pharmacy Trends In Canada (Including Provincial Restrictions)
Many people wonder whether they can order chlorpromazine online and how long it will take to arrive.
Canadian online pharmacies require a prescription to dispense chlorpromazine.
Some licensed Canadian online pharmacies will fill prescriptions across provinces and use courier delivery to reach patients.
Provincial regulations and controlled-drug rules can add steps that delay dispatch, such as verification calls and prior-authority paperwork.
Ordering from U.S. or international sellers is common but exposes patients to import rules and possible customs seizure.
Check provincial pharmacy regulators and Health Canada guidance before attempting cross-border orders.
Decision Flowchart For Buying Canadian Vs US
- Have A Canadian Prescription: Use a licensed Canadian online pharmacy for provincial coverage and verified DIN matching.
- No Canadian Prescription: Obtain an Rx from a Canadian prescriber before ordering domestically.
- Considering US Sellers: Expect customs checks and potential seizure; verify import regulations first.
Price Ranges By Package Size (With Provincial Differences)

Off-Label Patterns In Canadian Healthcare
- Refractory hiccups when standard antiemetics fail, especially in palliative care.
- Behavioural disturbances in paediatric or palliative settings with careful documentation.
- Off-label uses typically require clinician documentation and may trigger prior-authorisation reviews for public plans.
- Monitoring needs for off-label uses include ECG and relevant labs depending on patient risk factors.
How It Works In The Body
Patients want a simple explanation of how chlorpromazine calms symptoms and why it causes side effects.
Layman’s Explanation
Chlorpromazine reduces certain brain chemical signals, mainly dopamine, to calm hallucinations and severe agitation.
The drug also blocks other receptors, which helps with nausea but causes drowsiness and dry mouth.
Oral effects usually start within hours, and injections act faster for emergency control.
Clinical Detail From Health Canada Resources
| Receptor Target | Clinical Effect |
|---|---|
| Dopamine D2 Antagonism | Reduces psychotic symptoms; risk of extrapyramidal effects |
| Serotonin & Histamine Blockade | Contributes to sedation and antiemetic effects |
| Anticholinergic & Alpha-Adrenergic Blockade | Explains dry mouth, constipation, orthostatic hypotension |
Hepatic metabolism and variable half-life mean dose adjustments are needed in liver impairment.
Dosage & Administration
How do Canadian clinicians dose chlorpromazine for adults and special populations?
Standard Regimens Per Canadian Guidelines
| Indication | Starting Dose | Maintenance |
|---|---|---|
| Schizophrenia / Psychosis | 25–100 mg orally three times daily | 200–800 mg/day divided |
| Acute Agitation | IM/IV 25 mg/mL used cautiously | Titrated as clinically required in monitored setting |
| Nausea / Vomiting | 10–25 mg orally every 4–6 hours | Short course until symptoms resolve |
Always include DIN and strength on prescriptions for dispensing and reimbursement.
Adjustments By Patient Type (With Canadian Clinical Notes)
- Children: Use weight-based dosing (~0.5–0.55 mg/kg per dose) and titrate carefully.
- Elderly: Start at about half adult dose and monitor for hypotension and sedation.
- Hepatic/Renal Impairment: Reduce dose and titrate slowly due to accumulation risk.
- Dementia Warning: Routine use in dementia-related psychosis is not recommended due to increased mortality risk.
Contraindications & Side Effects
What risks should patients be told about before starting chlorpromazine?
Common (Health Canada-Approved List)
- Drowsiness and somnolence are common and may impair driving.
- Dry mouth, blurred vision and constipation are frequently reported.
- Orthostatic hypotension can cause dizziness on standing; monitor blood pressure at initiation.
- Weight gain and extrapyramidal symptoms such as tremor, rigidity and akathisia can occur.
- Photosensitivity is a known effect; advise sun protection in summer months.
Rare But Serious (With Canadian Pharmacovigilance Data)
- Tardive Dyskinesia: Watch for involuntary movements; report promptly to prescriber.
- Neuroleptic Malignant Syndrome: Look for high fever, rigidity and autonomic instability; seek emergency care.
- Blood Disorders: Leukopenia may present as unexplained fever or infection; stop drug and investigate.
- QT Prolongation & Seizures: Monitor ECG when combined with other QT-prolonging medicines.
- Absolute Contraindications: Comatose states, known phenothiazine hypersensitivity, severe bone marrow depression, pheochromocytoma, children under six months.
Comparable Medicines In Canada

- Practical Note: For acute agitation, haloperidol may be preferred for lower anticholinergic effects.
- Substitution: Always check DIN, provincial listing and patient comorbidities prior to a switch.
Current Research & Trends
What recent studies or trends affect how chlorpromazine is used in Canada?
Major Canadian Or International Studies 2022–2025
Recent literature through 2022–2025 has revisited first-generation antipsychotics in resource-limited settings and compared movement-disorder risks across drug classes.
Case series continue to document off-label use for intractable hiccups and palliative nausea control.
Canadian centres publish cohort analyses of prescribing patterns and adverse-event reporting, noting continued use in acute care and palliative settings where cost and injectables matter.
Pharmacogenomics interest exists but has limited routine application for chlorpromazine dosing to date.
Notes For Pharmacists
- Keep up with guideline updates from the Canadian Psychiatric Association and provincial formularies.
- Real-world safety data often informs provincial coverage decisions and prior-authorisation rules.
- Maintain a short linked bibliography in the pharmacy for clinicians seeking primary studies.

- Photosensitivity Advice: "Use sunscreen and wear a hat during sunny months to reduce risk."
- Movement Disorder Warning: "If you notice any new or unusual movements, call your prescriber immediately."
- Prior Authorisation Help: "If your claim is denied, provide DIN and indication details to your prescriber for review."
Regulatory Status
How is chlorpromazine regulated in Canada and why is the DIN important?
Health Canada Approval Process
- Manufacturers submit safety and efficacy evidence to Health Canada to obtain market authorisation.
- Successful submissions result in a Drug Identification Number (DIN) for a specific product, strength and formulation.
- Post-market surveillance is performed by Health Canada and provincial pharmacovigilance systems.
DIN Number Relevance
- The DIN uniquely identifies product, strength and formulation and is required for provincial reimbursement.
- Record the DIN on the patient medication profile and receipts when dispensing.
- If a patient presents an imported pack without a Canadian DIN, document it as a non-DIN import and verify active ingredient equivalence.
- Being on the WHO Essential Medicines List supports global supply continuity but does not alter Rx status in Canada.
