Phenergan
Phenergan
- In our pharmacy, you can buy phenergan without a prescription, with delivery in 5–14 days throughout Canada (English). Discreet and anonymous packaging.
- Phenergan (promethazine hydrochloride) is used for allergic conditions, motion sickness, nausea and vomiting, and as a sedative/pre‑operative agent; it is a first‑generation H1 antihistamine with anticholinergic and sedative properties and central antiemetic effects.
- Usual adult doses include 10–25 mg at night or 10 mg 2–3 times daily for allergies; 25 mg (single dose) for motion sickness given the night before or 1–2 hours before travel; 25–50 mg for nausea/vomiting, repeatable every 4–6 hours if needed. Not recommended in children under 2 years; paediatric dosing is weight‑based and should follow a physician’s guidance.
- Forms of administration include oral tablets (10 mg, 25 mg), elixir/syrup (1 mg/mL, 100 mL bottles), and suppositories (12.5 mg, 25 mg, 50 mg) — parenteral forms are used in clinical settings.
- Onset time: oral tablets or elixir generally begin to work within 20–60 minutes; suppositories may act within 15–60 minutes; intramuscular/intravenous routes act faster (around 10–20 minutes).
- Duration of action: antihistamine and antiemetic effects typically last about 4–6 hours; sedative effects can persist 6–12 hours depending on dose and individual sensitivity.
- Alcohol warning: do not consume alcohol while using phenergan — alcohol markedly increases drowsiness, sedation and the risk of respiratory depression and impaired coordination.
- The most common side effect is sedation (drowsiness); other common effects include dizziness, dry mouth, blurred vision, constipation, headache and mild hypotension; paradoxical excitation can occur, especially in children.

Online Pharmacy Trends In Canada (Including Provincial Restrictions)
Provincial pharmacy regulations influence how e‑pharmacies dispense prescription medicines across provincial lines.
Reputable Canadian online pharmacies require a valid prescription and typically verify identity before dispensing.
Cross‑border purchases from U.S. online retailers remain common but can carry customs, regulatory and safety considerations for Canadian buyers.
Price Ranges By Package Size (With Provincial Differences)
Prices vary by retailer, package size and whether a provincial drug plan covers the product.
Typical retail ranges seen in Canada are roughly: tablets (25‑pack) CAD $8–$25 and elixir (100 mL) CAD $10–$40.
Provincial plans such as ODB, PharmaCare or RAMQ can change out‑of‑pocket costs for eligible patients, so local coverage matters.
In‑store pickup prices may be higher than online member pricing, and occasional stockouts influence price and availability.
Canadian Patient Insights & Satisfaction Levels
Forum And Review Platforms (Reddit Canada, HealthBoards, AskDocs)
Canadian patients share real experiences on platforms such as Reddit (r/Canada, r/AskDocsCanada) and health forums.
Travel and parenting forums often discuss promethazine in practical terms — when to use it and how drowsiness plays out in daily life.
Reported Benefits And Challenges From Canadian Patients
Many report effective control of motion sickness, short‑term sedation and relief from nausea or allergy symptoms.
Parents often mention paediatrician warnings about avoiding promethazine in children under two due to respiratory risk.
Common complaints include excessive drowsiness, syrup taste and concerns about dosing accuracy for children.

Product Overview & Brand Variants
INN And Brand Names Used In Canada
The International Nonproprietary Name is promethazine hydrochloride.
Internationally the active ingredient is commonly marketed as Phenergan and under brand names such as Avomine, Lergigan and Prothiazine.
In many markets the branded product Phenergan is available in tablets and elixir, while generics of promethazine hydrochloride are commonly dispensed.
Legal Classification Under Health Canada
Health Canada market authorisations and provincial drug schedules determine legal availability and prescription status.
Promethazine is generally treated as a prescription medication in most regulatory jurisdictions and product pages should show DINs where applicable.
Pharmacists must counsel on substitution when dispensing generic equivalents in place of a brand name.

Indications In Local Canadian Medical Practice
Approved Uses (Health Canada DIN Context)
Promethazine is used for allergic reactions, motion sickness, nausea and vomiting, and as a sedative pre‑operatively where indicated.
When listing indications on a product page, connect each indication to the product monograph or DIN where available.
Off‑Label Patterns In Canadian Healthcare
Off‑label short‑term uses include short courses for insomnia or as adjunct antiemetic therapy when first‑line agents are unsuitable.
Any off‑label recommendation should be clearly identified and justified with clinical rationale and safety notes.
| Indication | Typical Adult Dose | Paediatric Note | DIN Reference |
|---|---|---|---|
| Allergy | 10–25 mg at night or 10 mg two–three times daily | 5–15 mg nocte for older children; not for <2 years | not specified |
| Motion Sickness | 25 mg night before or 1–2 hours prior | 12.5–25 mg single dose for children per prescriber | not specified |
| Nausea/Vomiting | 25–50 mg, repeatable every 4–6 hours if needed | Use specialist guidance for dose | not specified |
How It Works In The Body
Layman’s Explanation (Canadian Patient‑Friendly Tone)
Promethazine blocks histamine H1 receptors to reduce sneezing, itching and runny nose.
It also acts on brain pathways that control nausea and causes sedation, which can be helpful before travel or medical procedures.
Clinical Detail From Health Canada Resources
Pharmacologically, promethazine is a phenothiazine derivative with antihistaminic, sedative and antiemetic properties and is classified under ATC code R06AD02.
Metabolism is primarily hepatic and doses may accumulate in hepatic impairment, increasing risk of adverse effects.
Anticholinergic side effects such as dry mouth, blurred vision and constipation are clinically relevant and should be counselled on.
Quick Definitions For Product Pages
- Mechanism: H1 receptor antagonism and central antiemetic action.
- Onset: Typically within 20–60 minutes when taken orally.
- Duration: Several hours; repeat dosing per monograph if needed.
- Metabolism: Hepatic; caution in liver disease.
Dosage & Administration
Standard Regimens Per Canadian Guidelines
Adults commonly take 10–25 mg for allergic symptoms or 25 mg before travel for motion sickness.
For nausea, adults may use 25–50 mg and repeat every 4–6 hours as required, following prescriber instructions.
Adjustments By Patient Type (With Canadian Clinical Notes)
Children under two years must not receive promethazine due to risk of fatal respiratory depression.
Older children receive weight‑ or age‑adjusted dosing and a prescriber should provide clear instructions.
Elderly patients should start at lower doses due to increased sedation, confusion and hypotension risk.
Administration Checklist
- Confirm concentration for syrup (1 mg/mL) before measuring.
- Use an oral syringe or dosing device for accuracy with elixir.
- Avoid driving or operating machinery while drowsy.
- Avoid alcohol and other CNS depressants.
Contraindications & Side Effects
Common (Health Canada‑Approved List)
Absolute contraindications include hypersensitivity to promethazine or phenothiazine derivatives, children under two years, and comatose or severely depressed CNS states.
Common adverse effects are sedation and drowsiness, dizziness, dry mouth, blurred vision, constipation and mild hypotension.
Rare But Serious (With Canadian Pharmacovigilance Data)
Serious but uncommon events include respiratory depression in young children, severe anticholinergic effects and extrapyramidal symptoms.
Canadian adverse event reports are captured by national pharmacovigilance systems and should be referenced when discussing rare events.
If severe reactions or breathing concerns occur, seek immediate medical attention and report the event to Health Canada.
When To Seek Urgent Care
- Marked difficulty breathing or slow breathing.
- Severe confusion, fainting or seizures.
