Questions

About Progesterone Capsules

If your question isn't here, your physician is one message away after you start your intake.

• What is progesterone?

  Progesterone is a natural hormone made mainly by the ovaries after ovulation. It plays a key role in the menstrual cycle, pregnancy, and — importantly for hormone therapy — in balancing the effects of estrogen on the uterine lining. Prescription progesterone is available as oral micronized capsules, vaginal products, or compounded topical preparations, and is often used as part of women's hormone therapy alongside estrogen.

• What is progesterone used for?

  The most common medical use is uterine (endometrial) protection in women taking systemic estrogen. It's also used to help with perimenopausal sleep disruption, mood changes, cycle irregularities, and — under certain protocols — luteal-phase or fertility support. Some patients notice calmer sleep and steadier mood taking oral micronized progesterone at night, though responses vary.

• How does progesterone work?

  Progesterone binds to progesterone receptors throughout the body. In the uterus, it opposes estrogen's growth-promoting effect on the endometrial lining. In the brain, its natural metabolite (allopregnanolone) interacts with GABA receptors, which is why oral micronized progesterone often has a calming, sleep-promoting effect. It also influences breast tissue, mood, temperature, and fluid balance.

• Am I a good candidate?

  You may be a candidate if you're taking systemic estrogen and still have a uterus, if you have perimenopausal sleep or mood symptoms, or if your physician identifies a role for progesterone in your specific hormone plan. Candidacy depends on your symptoms, cycle history, uterus status, breast and cancer history, clotting risk, and current medications.

• Who should not take progesterone?

  Progesterone may not be appropriate if you have unexplained vaginal bleeding, known or suspected breast cancer or other hormone-sensitive cancer, active or recent blood clots, significant liver disease, or a known allergy to progesterone or peanut oil (which some micronized capsules contain). It's generally avoided in pregnancy unless specifically prescribed for that purpose.

• Do I need progesterone if I take estrogen?

  If you still have a uterus and take systemic estrogen (patch, cream, gel, oral, pellet), you generally need progesterone as well. Without it, estrogen can overstimulate the uterine lining, leading to abnormal thickening and, over time, increased risk of endometrial cancer. Patients without a uterus often don't need progesterone — your physician makes the call.

• What's the difference between oral capsules and topical cream?

  Oral micronized progesterone is the best-studied form for endometrial protection and typically has the strongest sleep-supporting effect thanks to its metabolites. Topical progesterone cream may be used for perimenopausal symptoms and body-wide effects, but transdermal absorption is variable, so it's generally not considered reliable on its own for uterine protection at typical over-the-counter doses. Your physician chooses the form based on your goals and risks.

• How is oral progesterone taken?

  Oral micronized progesterone is usually taken at bedtime because of its calming, drowsy effect. Depending on your protocol, it may be dosed continuously (every night) or cyclically (specific days of the month). Take with a small snack if it upsets your stomach. Don't change the schedule on your own — your physician sets it based on whether you're pre-, peri-, or post-menopausal and whether you're on estrogen.

• Do I need labs before starting?

  Not always. Perimenopausal and menopausal symptoms are often diagnosed from age, history, and symptoms. Labs are helpful when the picture is unclear, when periods are still occurring, when early menopause is suspected, when multiple hormones are being used, or when there are overlapping concerns like thyroid, low libido, fatigue, weight changes, or hair loss.

• How long does it take to work?

  Sleep and mood effects can be noticeable within the first few nights for some patients, though full benefit often takes several weeks. Cycle regulation and bleeding pattern changes usually settle over 2 to 3 cycles. If you don't see benefit after a fair trial, your physician can adjust dose, timing, or route.

• What are common side effects?

  Common effects include drowsiness (why it's taken at night), bloating, breast tenderness, headache, mood changes, dizziness on standing, and spotting or breakthrough bleeding, especially in the first few cycles. Seek urgent care for chest pain, shortness of breath, one-sided leg swelling, sudden severe headache, weakness on one side, vision changes, or signs of a serious allergic reaction.

• Can progesterone cause breast cancer or blood clots?

  Risk depends on the type of progestogen used, the estrogen it's paired with, dose, duration, age, and personal and family history. Micronized bioidentical progesterone has a different risk profile than older synthetic progestins used in some legacy hormone regimens. Tell your physician about past clots, clotting disorders, smoking, migraines with aura, breast or gynecologic cancer history, or a strong family cancer history. A responsible clinic will never claim any hormone has zero risk.

• Will progesterone make me gain weight?

  Progesterone itself is not a weight-gain drug, but some patients notice temporary bloating or breast fullness that can feel like weight change, especially at the start. True weight change during menopause has many drivers — sleep disruption, muscle loss, insulin resistance, stress, and life stage — and is best addressed through overall care, not by adjusting progesterone in isolation.

• Can I adjust my dose myself?

  No. Don't change the dose, timing, or schedule without medical guidance. Too little may not protect the uterus adequately when you're on estrogen; too much can worsen drowsiness, mood effects, or bleeding. Dose changes should be based on symptoms, side effects, bleeding pattern, and your overall hormone plan.

• How long do most patients stay on progesterone?

  There is no single right duration. Many patients use progesterone for as long as they take estrogen, or through the perimenopause transition. Treatment should be reviewed regularly — symptoms, side effects, bleeding, breast health, and personal preferences all factor in.

• Can progesterone be combined with estrogen or testosterone?

  Yes. Progesterone is commonly paired with systemic estrogen for endometrial protection and symptom support, and may be part of a broader plan that includes low-dose testosterone for women when appropriate. Combining hormones always requires physician oversight and, in most cases, some baseline labs.

• When should I contact my physician?

  Contact us for unexpected bleeding, breast changes, severe headaches, mood changes that feel out of character, pelvic pain, leg swelling, chest pain, shortness of breath, persistent dizziness, or any symptom that feels concerning. Also reach out if symptoms haven't improved after a fair trial.

• How is it shipped?

  Discreetly, in plain packaging, from a licensed 503A compounding pharmacy. Most orders ship in 24 to 48 hours after physician approval.

• What if I'm not approved for treatment?

  If a physician reviews your intake and does not approve you for treatment, the cost of your medication is fully refunded. Initial evaluation fees are non-refundable.
