Medroxyprogesterone
Medroxyprogesterone
- In our pharmacy, you can buy medroxyprogesterone without a prescription, with delivery available across Canada in discreet packaging. Medroxyprogesterone is prescription-only in most countries, but availability without a receipt may vary by pharmacy and jurisdiction.
- Medroxyprogesterone is used for contraception, abnormal uterine bleeding, endometriosis, secondary amenorrhea, and some hormone-sensitive cancers. It is a progestin (synthetic progesterone) that works by suppressing ovulation, thinning the endometrium, and changing cervical mucus.
- The usual dose depends on the condition: 150 mg intramuscularly every 3 months for contraception, 104 mg subcutaneously every 3 months for contraception, or 5–10 mg orally daily for 5–10 days for gynecologic conditions. Cancer treatment doses are higher and individualised.
- The form of administration is an oral tablet, an intramuscular injection, or a subcutaneous injection.
- How fast it starts working depends on the form: oral tablets may begin working within hours, while injectable contraception may require up to 7 days for full contraceptive protection if not started at the beginning of the menstrual cycle.
- The duration of action is long-lasting: injectable forms typically work for about 12–13 weeks, while oral courses are usually taken for 5–10 days per cycle depending on the indication.
- Alcohol is best avoided or limited, especially if you feel dizzy, drowsy, or have liver problems, because alcohol may worsen side effects and increase safety concerns.
- The most common side effects are menstrual irregularities or amenorrhea, weight gain, headache, bloating, dizziness, mood changes, acne, and decreased libido.

Availability And Price Landscape In Canada
Major National Pharmacy Chains
Looking for medroxyprogesterone in Canada often starts with a simple question: is the oral tablet on the shelf, or does it need to be ordered in?
In practice, chain pharmacies such as Shoppers Drug Mart, Rexall, and London Drugs may carry or order Provera tablet strengths, but stock can vary by province, branch, and local prescriber demand.
The injectable forms are more likely to be coordinated through clinics, family practices, or sexual health services than picked up like a routine retail item, especially for injectable birth control schedules that need exact timing.
Online Pharmacy Trends In Canada
Canadian shoppers increasingly compare in-store and online Canadian pharmacy pricing because private insurance, provincial drug plans, and dispensing fees can change the final out-of-pocket total.
Some provinces have formularies or special authority rules that affect whether a patient gets coverage for a Provera 5 mg or Provera 10 mg prescription, and the same drug can cost differently across provinces and even within the same city.
Cross-border U.S. prices may look lower on a screen, but Canadian patients often cannot easily move U.S. supply into provincial dispensing workflows, so the cheapest posted price is not always the most practical option.
In our online pharmacy, medroxyprogesterone is available without a prescription, with discreet delivery to Canada in 5-14 days.
Price Ranges By Package Size
| Form | Typical Purchase Channel | Canadian Price Range |
|---|---|---|
| Provera 2.5 mg tablets | Retail or online Canadian pharmacy | Varies by province, stock, and plan coverage |
| Provera 5 mg tablets | Often ordered in by chain pharmacies | Varies by province, stock, and plan coverage |
| Provera 10 mg tablets | Retail, clinic-linked pharmacy, or online | Varies by province, stock, and plan coverage |
| IM suspension 150 mg/mL | Usually clinic-coordinated or special order | Varies by province, stock, and plan coverage |
| SC injection 104 mg/0.65 mL | Usually clinic-coordinated or special order | Varies by province, stock, and plan coverage |
What to ask the pharmacist: Do you stock the exact strength and dosage form, what is the DIN, and does my plan cover the oral tablet or injection?
Patient Experiences And Satisfaction In Canada
Forum And Review Platforms
What do Canadian patients actually say before they decide on medroxyprogesterone?
Across Reddit Canada, HealthBoards, AskDocs, and local community health-centre discussions, the same themes keep coming up: convenience, bleeding control, and side effects.
Reported Benefits And Challenges
- Many people like the convenience of an injection every 12 to 13 weeks.
- Some use it for menstrual suppression or endometriosis symptom management and appreciate fewer cycle disruptions over time.
- Others find irregular bleeding frustrating, especially early in treatment.
- Weight gain, headache, and mood changes are common concerns in patient stories.
- Missed injection timing matters: if more than 14 weeks have passed, backup contraception and pregnancy assessment are needed.
Local satisfaction often depends on why the product was started in the first place, because contraception, cycle control, and pain management are not the same goal.
Anecdotes are not the same as clinical evidence, but they matter when a person is deciding whether to keep going after the first few months.
In many cases, follow-up injections are easier to keep on schedule through a walk-in sexual health clinic or family practice than through retail pick-up alone.
Product Overview And Brand Variants
INN And Brand Names Used In Canada
Medroxyprogesterone is the International Nonproprietary Name, which means it is the standard scientific name used across markets.
Canadian shoppers may see Provera for oral tablets, Depo-Provera for the injectable form, and Depo-SubQ Provera 104 for the subcutaneous injection.
Package names can differ from U.S. references, so the strength and dosage form matter more than the brand name alone.
Legal Classification Under Health Canada
- Prescription status
- Prescription-only in Canada.
- DIN
- The Drug Identification Number confirms the exact product, strength, and dosage form on the Canadian package.
- Brand interchangeability
- Some products with similar names are not interchangeable, especially when comparing tablets with depot injections.
That distinction matters when a patient hears “Provera” in conversation but receives a different product at the counter.
Indications In Local Canadian Medical Practice
Approved Uses In Health Canada DIN Context
Why do Canadian prescribers reach for medroxyprogesterone?
The main reasons are contraception, abnormal uterine bleeding, secondary amenorrhea, endometriosis symptom control, and selected oncology uses.
Off-Label Patterns In Canadian Healthcare
| Indication | Usual Form | Common Canadian Care Setting |
|---|---|---|
| Contraception | 150 mg IM or 104 mg SC | Family practice, sexual health clinic |
| Abnormal uterine bleeding | 5 to 10 mg oral tablets | Family practice, gynaecology |
| Secondary amenorrhea | 5 to 10 mg oral tablets | Family practice, gynaecology |
| Endometriosis symptom control | 5 to 10 mg oral tablets | Gynaecology |
| Selected cancer regimens | 200 to 400 mg IM weekly, individualized | Oncology |
Off-label use is possible in Canadian practice, but coverage and dispensing can still vary by indication and plan.
A DIN confirms a marketed product in Canada, while the approved use still depends on the exact formulation and labelling.
How It Works In The Body
Layman’s Explanation
Medroxyprogesterone is a progestin, which means it acts like a progesterone-type hormone.
In plain language, it helps change how the uterus and reproductive hormones behave so that ovulation may be prevented in some formulations, the uterine lining becomes thinner, and bleeding or pregnancy risk can be reduced depending on the product and dose.
Clinical Detail From Health Canada Resources
Simple flow:
Depot injection or oral tablet → systemic progestogen effect → altered ovulation and endometrial response → contraception, reduced bleeding, or symptom control.
The ATC classification reflects those uses: G03AC06 for systemic progestogens, L02AB02 for endocrine therapy in cancer, and G03DA02 for pregnen(4) derivatives.
That is also why the injection lasts for months, while the tablet is taken in short courses.
Dosage And Administration
Standard Regimens Per Canadian Guidelines
Dosage questions are usually the first thing patients ask when picking up a medroxyprogesterone tablet or booking a shot.
| Dose | Route | Interval | If Missed |
|---|---|---|---|
| 150 mg | IM | Every 3 months | Give as soon as possible; if more than 14 weeks, use backup contraception and assess for pregnancy |
| 104 mg | SC | Every 3 months | Give as soon as possible; if more than 14 weeks, use backup contraception and assess for pregnancy |
| 5 to 10 mg | Oral | Daily for 5 to 10 days | Take when remembered; if close to next dose, skip and do not double |
Adjustments By Patient Type
Children need specialist guidance, and routine pre-puberty contraceptive use is not recommended because safety data are limited.
Older adults have insufficient data for a standard dose adjustment, so use is generally reserved for approved indications such as cancer.
Patients with liver disease need caution because medroxyprogesterone is metabolized hepatically, and significant hepatic impairment is a contraindication.
Room-temperature storage is important, especially when medication is moved between the pharmacy, home, and clinic.
Contraindications And Side Effects
Common Effects
| Common | Serious |
|---|---|
| Menstrual irregularities or amenorrhea | Pregnancy-related exposure |
| Weight gain | Active thromboembolic disease |
| Headache | Severe liver dysfunction or disease |
| Abdominal bloating or pain | Known or suspected breast or genital cancer |
| Dizziness | Unexplained vaginal bleeding |
| Mood changes or depression | Allergy to medroxyprogesterone or excipients |
| Acne and hair loss | Bone loss concerns with long-term DMPA use |
| Decreased libido | Higher-monitoring situations: depression, diabetes, hypertension, migraine, hyperlipidemia |
Warning: long-term DMPA use may be associated with bone loss concerns, especially in patients already at risk of osteoporosis.
That is why a patient with depression, diabetes, hypertension, migraine, or hyperlipidemia should have a more careful review before starting or continuing treatment.
Comparable Medicines In Canada
Alternatives Table
| Alternative | Typical Use | Canadian Purchase Context |
|---|---|---|
| Norethisterone | Hormonal cycle control | Oral daily option |
| Levonorgestrel | Contraception, implant forms | Oral or device-based access |
| Desogestrel | Progestin-only contraception | Oral daily option |
| Dienogest | Endometriosis | Often used for symptom control |
| Combined estrogen/progestin products | Contraception or hormone therapy | Pills, patches, or rings |
Depo-Provera alternatives are not automatically interchangeable, and formulation differences matter for both effect and coverage.
Pros: long-acting dosing, familiar contraceptive schedule, and useful cycle control for some patients.
Cons: irregular bleeding, weight gain concerns, mood changes, and the need for timely follow-up injections.
Current Research And Trends
Major Studies And Practice Themes
- Long-acting reversible contraception remains a major focus because many patients value fewer dosing reminders.
- Bone-health monitoring with DMPA remains important, especially for people already at risk of osteoporosis.
- Patient continuation rates are strongly tied to counselling about bleeding changes and what to expect early on.
- Mood-related outcomes continue to be discussed in both clinical practice and patient forums.
Canadian care often balances efficacy, convenience, and coverage, particularly when patients compare injection schedules against oral options.
In day-to-day pharmacy practice, the question is usually not whether the drug works, but whether the patient can stay on schedule and tolerate it well enough to continue.
Common Patient Questions In Canada
Practical Questions
- Do I need a prescription?
- Yes, medroxyprogesterone is prescription-only in Canada.
- Can I get it at Shoppers Drug Mart or Rexall?
- Sometimes, but availability depends on the branch, province, and exact strength.
- Is it covered by OHIP, BC PharmaCare, or RAMQ?
- Coverage varies by province, plan, and indication.
- What happens if I’m late for my shot?
- If more than 14 weeks have passed, backup contraception and pregnancy assessment are needed.
- Is the injection better than tablets?
- It depends on the treatment goal, bleeding pattern, and how well the patient can follow the schedule.
Pharmacy staff may need the DIN and exact strength before they can confirm stock or coverage.
Regulatory Status
Health Canada Approval Process
In Canada, legal sale depends on Health Canada authorisation and the presence of a valid Drug Identification Number.
That DIN helps pharmacists and patients confirm the exact product, strength, and dosage form before dispensing.
DIN Number Relevance
- DIN
- Confirms the approved Canadian product.
- Market authorisation
- Supports legal sale of the specific formulation.
- Provincial coverage
- May still affect whether the product is paid for or requires special authority.
Imported or cross-border products should not be assumed equivalent without verification, even if the brand name looks familiar.
Visual Recommendations
Infographic Ideas For Canadian Context
A good pharmacy page should make medroxyprogesterone easier to understand at a glance.
Useful visuals include a dosage timeline, a Canada coverage snapshot, a brand and form comparison chart, and a warning box for when to call the pharmacist.
A simple diagram showing IM versus SC injection intervals can help patients understand why one product is given every 12 to 13 weeks and the other is used on the same schedule.
Storage icons for room temperature, light protection, and freezing warnings are also worth adding.
Buying And Storage Advice
In-Store Versus Online Canadian Purchase Tips
The safest way to buy medroxyprogesterone is to confirm the exact formulation, strength, and DIN before checkout.
Ask whether the pharmacy has the oral tablet on hand or needs to order it in, and compare in-store versus online Canadian pharmacy pricing before making a decision.
Some patients compare U.S. prices first, but Canadian dispensing rules and coverage are different, so the lowest advertised price is not always the easiest option to fill.
Proper Storage With Canadian Climate Considerations
| Storage Point | What To Do |
|---|---|
| Temperature | Keep at 15 to 25°C |
| Light | Protect from light |
| Freezing | Do not freeze |
| Appearance | Do not use injectable suspension if it looks clumpy or discoloured |
That last point matters after shipping in winter, when packages can sit in cold mailboxes or delivery trucks longer than expected.
Guidelines For Proper Use
Canadian Doctor And Pharmacist Advice Style
Use medroxyprogesterone exactly as prescribed, keep injection appointments on time, and report bleeding or mood changes early rather than waiting months.
Patients using it long term should review bone-health risk, especially if there is already a history of osteoporosis or other risk factors for bone loss.
Ask your pharmacist about:
- Whether the product is Provera tablet, IM suspension, or subcutaneous injection.
- How to handle a late injection or missed tablet.
- Whether depression, diabetes, hypertension, migraine, or hyperlipidemia changes the monitoring plan.
- Whether a provincial drug plan or private insurance may cover the chosen formulation.
Red flag: pregnancy, severe liver disease, unexplained vaginal bleeding, or a clotting history should be reviewed before treatment is continued.
Treatment goals also differ by indication, so contraception, hormonal bleeding control, and oncology use should never be treated as the same plan.
