Progesterone is a hormone medicine used in clinician-directed treatment plans, including selected menopause and hormone-support regimens. Progesterone can be bought online, with current pricing shown during ordering and the dose or strength chosen to match the directions you have been given. Our process helps you review the active ingredient, quantity, storage needs, and safety considerations before the medicine is supplied through licensed pharmacy channels.
Oral progesterone is often discussed as micronized progesterone, natural micronized progesterone, or bioidentical progesterone because the active hormone is structurally similar to progesterone made by the body. Those terms can be useful, but they do not replace the need to match the exact strength, form, and schedule on your medication label. If you are switching from a brand name or from another hormone product, confirm that the active ingredient and route are the same.
Price, Strength Selection, and Ordering Details
Progesterone cost can vary with strength, quantity, brand or generic supply, and the pharmacy source used for the order. View the current price during checkout, then choose the dose or strength shown for Progesterone that matches your clinician’s directions. Do not choose a higher strength only because it appears to be a better value; hormone therapy depends on the intended regimen, not only on tablet or capsule count.
Common search terms include progesterone 100mg, progesterone 200mg, progesterone tablets 100mg, and progesterone tablet 200mg. Those searches usually reflect the strength someone was told to use, but the medicine still needs to match the exact active ingredient, route, and schedule. If your label uses brand language such as Prometrium, or says micronized progesterone, keep that wording available when reviewing the order.
Some U.S. customers use US delivery from Canada for cash-pay medication access when local costs are difficult to manage. The practical buying step is straightforward: match the medication name, strength, and quantity to your directions, then keep the original label and patient leaflet once the order arrives. If order details need clarification, we may help confirm them before the pharmacy supplies the medicine.
Quick tip: Keep a photo of your current medication label so the name, strength, and directions are easy to compare.
What Progesterone Is Used For
Progesterone is a reproductive hormone that helps regulate the uterine lining and supports several hormone-related processes. In menopause care, oral micronized progesterone is commonly used with estrogen in people who still have a uterus, because unopposed estrogen can overstimulate the uterine lining. Your clinician may also use progesterone in other hormone-support plans based on diagnosis, age, bleeding pattern, and treatment goals.
Progesterone hormone therapy is not a general cure for fatigue, mood changes, sleep problems, acne, hair growth, or irregular cycles without a medical assessment. Those symptoms can overlap with perimenopause, thyroid disease, polycystic ovary syndrome, medication effects, and other conditions. If menopause symptoms are part of the reason for treatment, the Menopausal Symptoms section can help you place progesterone within the broader hormone-therapy conversation.
People also ask about progesterone tablets in pregnancy or fertility care. Progesterone may be used in some reproductive-medicine settings, but timing, route, monitoring, and duration can differ from menopause regimens. Do not assume that a hormone medicine used for one purpose can be used the same way for another purpose. If cycle control, bleeding, fertility, or pregnancy support is involved, ask which exact product and schedule your care team intends.
Oral Progesterone, Micronized Progesterone, and Brand Comparisons
Oral micronized progesterone is a specific form of progesterone medicine taken by mouth. Micronized means the hormone particles are made smaller to support absorption. Many people call it natural progesterone or bioidentical progesterone, but those descriptions are not a safety guarantee and do not mean every progesterone product works the same way.
Brand-reference products and generics may be discussed together because they contain progesterone as the active ingredient. For example, Prometrium 100mg is a related brand-reference oral micronized progesterone product. A brand name on past packaging, an insurance record, or a clinic note can help identify what you used previously, but the active ingredient, strength, and route still matter most.
Progesterone pills, progesterone hormone tablets, creams, injections, and compounded preparations are not automatically interchangeable. Absorption and safety information can differ by route and formulation. If your directions specify oral micronized progesterone, avoid substituting an over-the-counter cream or a compounded mixture unless your clinician has specifically approved that change.
| Term you may see | What it usually means | Buying point to confirm |
|---|---|---|
| Progesterone | The active hormone ingredient | Match the route, strength, and quantity |
| Micronized progesterone | Progesterone processed for oral absorption | Confirm it matches your label language |
| Natural or bioidentical progesterone | Plain-language wording for body-identical hormone structure | Do not treat the term as a substitute for product identity |
| Prometrium micronized progesterone | Brand-reference language for an oral progesterone product | Check whether your directions allow a brand or generic |
How Oral Progesterone Is Usually Taken
Progesterone schedules vary by treatment reason. Some people take oral progesterone daily, while others use a cyclic schedule for part of each month. Bedtime dosing is common in many regimens because dizziness or drowsiness can occur, but timing should follow the directions on your medication label.
Take progesterone consistently and avoid changing the number of capsules or tablets without medical guidance. Strengths such as 100 mg and 200 mg are often discussed online, but they are not interchangeable simply because both contain progesterone. A 200 mg direction can mean a different regimen than two 100 mg doses, depending on the clinical plan and product instructions.
If you miss a dose, follow the instructions that came with your medicine or contact a healthcare professional for guidance. Doubling doses can increase side effects such as sedation, dizziness, nausea, or mood changes. If drowsiness is new to you, avoid driving or hazardous tasks until you understand how the medication affects you.
Why it matters: Hormone therapy works best when the active ingredient, strength, timing, and treatment goal all line up.
Storage, Handling, and Travel
Store progesterone in its original container, away from excess heat, moisture, and bathroom humidity unless the package directions say otherwise. Keep the patient leaflet with the medicine so instructions remain available throughout treatment. Do not use capsules or tablets after the expiry date on the label.
Travel is easier when medication stays in labeled packaging. This is especially useful during airport screening or when crossing borders with a hormone medicine. Avoid leaving progesterone in a hot car, freezing conditions, or a damp bag for long periods, because poor storage can affect medication quality.
When timing matters for your regimen, pack enough doses for travel days and time-zone changes. If the medicine causes sleepiness, plan the first travel dose carefully so you are not unexpectedly impaired while driving or navigating unfamiliar settings. Orders may include prompt, express shipping depending on order details and pharmacy handling requirements.
Side Effects, Warnings, and Monitoring
Progesterone can cause side effects even when it is used correctly. Common effects may include drowsiness, dizziness, headache, breast tenderness, bloating, nausea, abdominal discomfort, mood changes, and changes in vaginal bleeding. Some effects are more noticeable when starting treatment or after a strength or timing change.
Unexpected vaginal bleeding should be taken seriously, especially if it is heavy, persistent, or occurs after menopause. When progesterone is used with estrogen, the overall hormone-therapy risk discussion may include blood clots, stroke, heart disease, breast cancer, dementia in older patients, and endometrial cancer risk if estrogen is not balanced appropriately in people with a uterus. Your personal risk depends on age, uterus status, medical history, dose, route, and duration of therapy.
Seek urgent medical help for chest pain, sudden shortness of breath, one-sided leg swelling, sudden severe headache, fainting, vision changes, yellowing of the skin or eyes, or symptoms of a severe allergic reaction. Strong sedation, worsening depression, suicidal thoughts, or major mood changes also need prompt clinical attention. Progesterone is a hormone medicine, not a general sleep or anxiety treatment, even though sleepiness can happen.
Important cautions can include a history of blood clots, stroke, liver disease, unexplained vaginal bleeding, hormone-sensitive cancers, severe depression, migraine patterns, pregnancy status, and other hormone therapies. Tell your healthcare professional about all estrogen products, progestins, contraceptives, patches, creams, supplements, and nonprescription hormone products you use. Duplicate hormone exposure can happen when products are combined without a clear plan.
Drug interactions may involve alcohol, sedatives, sleep medications, seizure medicines, some anti-infectives, and drugs that affect liver enzymes. These can increase drowsiness or alter hormone levels. Ingredient allergies also matter; some oral micronized progesterone products have historically contained peanut oil, while formulations can differ. Read the ingredient list for the exact medicine you receive and ask about alternatives if a food or excipient allergy is relevant.
Related Hormone Therapy Choices
Progesterone may be part of a wider women’s health plan, especially when menopause symptoms, uterine protection, bleeding patterns, contraception, or endometriosis-like symptoms are being evaluated. The broader Women’s Health category can help you see adjacent therapies, while Women’s Health Guides provide background reading for common hormone questions.
Some people are prescribed a separate estrogen and progesterone plan. Others use a combined hormone product when that route fits the clinical goal. Estalis is a related estrogen-progestin patch option, but it is not a simple substitute for oral micronized progesterone. Route, active ingredients, uterine status, and side-effect tolerance all influence the choice.
Other women’s health medicines may come up for different reasons. Mirena is an intrauterine system used in contraception and selected gynecologic contexts, while Nextstellis is an oral contraceptive product. If unwanted hair growth or androgen-related symptoms are part of the discussion, What Is Hirsutism can help frame questions to raise with a clinician.
Menopause care may also involve estrogen-only products, nonhormonal symptom management, or different progestins. A background article on Premarin for menopause symptoms and hormonal balance explains another hormone-therapy pathway. Because these medicines have different active ingredients and risk profiles, do not switch between them without a clear treatment plan.
Questions to Ask Before Starting or Refilling
Before starting Progesterone or refilling it after a gap, ask what treatment goal the medicine is serving. The answer may be endometrial protection with estrogen, cycle regulation, luteal support, or another hormone-related reason. Knowing the goal helps you understand the schedule and what changes should trigger follow-up.
Ask whether your regimen is continuous or cyclic, whether bedtime use is preferred, and what to do if bleeding changes. It is also useful to ask how long the medicine should be used before reassessment. Hormone therapy is often revisited over time as symptoms, age, uterus status, and risk factors change.
Bring a complete medication list to appointments, including sleep aids, alcohol use, seizure medicines, antibiotics or antifungals, supplements, creams, patches, and contraceptives. If you are trying to become pregnant, are pregnant, or are using fertility treatment, raise that point before using any progesterone medicine. Reproductive goals can change the best route, timing, and monitoring plan.

What is Progesterone used for?
Progesterone is a hormone medicine used in selected clinician-directed treatment plans. It is commonly discussed in menopause care, especially with estrogen in people who still have a uterus, and may also be used in other hormone-support situations based on diagnosis and treatment goals.
Is micronized progesterone the same as natural progesterone?
Micronized progesterone is progesterone processed into smaller particles to support oral absorption. It is often called natural or bioidentical progesterone because the hormone matches the body’s progesterone structure, but those terms do not replace checking the exact medicine, strength, route, and directions.
When is oral progesterone usually taken?
Many oral progesterone regimens are taken at bedtime because dizziness or drowsiness can occur. Some schedules are daily, while others are cyclic. Follow the directions on your medication label and ask a healthcare professional before changing timing or strength.
What side effects can Progesterone cause?
Common side effects may include sleepiness, dizziness, headache, breast tenderness, bloating, nausea, mood changes, and changes in vaginal bleeding. Seek urgent care for chest pain, shortness of breath, one-sided leg swelling, sudden severe headache, vision changes, jaundice, or signs of a serious allergic reaction.
Can Progesterone be used instead of Prometrium?
Progesterone and Prometrium may be discussed together when oral micronized progesterone is intended, but substitution depends on the active ingredient, strength, route, and directions. Check whether your clinician intended a specific brand or an equivalent progesterone medicine.
Does Progesterone help with sleep or anxiety?
Progesterone can cause drowsiness or sedation in some people, which is why bedtime dosing is common in many regimens. That does not make it a general sleep or anxiety treatment. New or worsening mood symptoms should be discussed with a healthcare professional.
