How to Order Without Prescription	Online Pharmacy (prescription required in the United States)

Primolutn is a progestin medication whose active ingredient is norethindrone (also known globally as norethisterone). In the United States, medicines containing norethindrone are widely used by gynecologists to help regulate menstrual cycles, treat abnormal uterine bleeding, manage endometriosis symptoms, and induce withdrawal bleeding in secondary amenorrhea. Primolutn is typically supplied as 5 mg oral tablets. While it is a familiar therapy worldwide, it remains prescription-only in the U.S. and should be used under the guidance of a licensed healthcare professional.

As a synthetic form of the hormone progesterone, norethindrone binds to progesterone receptors and stabilizes the endometrium (the inner lining of the uterus). By counteracting unopposed estrogen and suppressing gonadotropins at sufficient doses, Primolutn can reduce bleeding, relieve pelvic pain related to endometriosis, and bring on a predictable withdrawal bleed when clinically indicated. It is not a contraceptive at the 5 mg dose used for these conditions; for birth control, lower-dose norethindrone (0.35 mg daily) is used as a progestin-only pill, which is a different regimen and indication.

Primolutn price and availability in the USA

In the U.S., norethindrone products are widely available through retail pharmacies, hospital outpatient pharmacies, and mail-order services. Pricing varies by brand versus generic, tablet strength, quantity, insurance coverage, and pharmacy location. Generic norethindrone options often offer significant savings compared with branded products and are therapeutically equivalent when FDA-approved as generics. Most patients pay less with insurance; those paying cash can often reduce out-of-pocket costs by using mail-order services, pharmacy discount programs, or manufacturer coupons when available.

For reference, many U.S. patients find that a 30- to 60-tablet supply of 5 mg norethindrone is moderately priced compared with other hormone therapies, although exact costs differ across regions and insurance plans.

Primolutn in the United States

Getting Primolutn in the U.S. is straightforward when you have a valid prescription. Simply select the correct strength and quantity, complete the order details with your pharmacy, and arrange payment and delivery. If you are switching from another progestin or therapy, confirm the dosing schedule with your clinician to ensure a smooth transition and avoid gaps in treatment.

What is Primolutn (norethindrone)?

Primolutn contains norethindrone (norethisterone), a synthetic progestin that mimics the effects of the body’s natural progesterone. Progesterone is crucial for regulating the menstrual cycle, maintaining endometrial stability, and supporting various reproductive functions. By binding to progesterone receptors, norethindrone transforms the endometrium into a secretory state, reduces unopposed estrogen effects, and can suppress ovulation at sufficient doses. These actions make Primolutn useful for addressing irregular bleeding, endometriosis-related pain, and secondary amenorrhea.

In the U.S., norethindrone is available in multiple formulations and strengths, each indicated for different uses. The 5 mg tablets used with Primolutn-type regimens are typically prescribed for abnormal uterine bleeding, endometriosis, and to induce withdrawal bleeding. Lower doses (0.35 mg daily) are used as progestin-only contraceptive pills and are not interchangeable with the higher-dose therapeutic regimens described on this page.

Always follow your healthcare professional’s dosing instructions. Do not substitute products, strengths, or regimens without medical guidance, as doing so could lead to ineffective treatment or unintended side effects.

Primolutn for abnormal uterine bleeding (AUB)

Abnormal uterine bleeding includes heavy, prolonged, or unpredictable bleeding that is not consistent with a normal menstrual pattern. Common causes include hormonal imbalance, ovulatory dysfunction, fibroids, polyps, endometrial hyperplasia, and certain medical conditions or medications. After evaluation, clinicians may prescribe a progestin like norethindrone to stabilize the endometrium and reduce bleeding.

Typical regimens for AUB with norethindrone 5 mg may include short courses (for example, 5 mg two or three times daily for 5–10 days) or cyclic therapy (e.g., 5 mg once or twice daily for 10–14 days per cycle), depending on the clinical situation. Many patients observe improvement within a few days, with bleeding reduction and transition to a predictable withdrawal bleed after stopping the medication. Your exact dose and schedule should be individualized by your clinician based on the severity of bleeding, underlying causes, and your treatment goals.

Progestin therapy can be used alone or alongside other strategies such as nonsteroidal anti-inflammatory drugs (NSAIDs), tranexamic acid (if appropriate), or long-acting intrauterine devices (IUDs) containing levonorgestrel. Your clinician will help you weigh options, especially if you have risk factors that influence the choice of therapy.

Why many clinicians choose Primolutn for AUB

Progestin therapy is a mainstay in AUB management because it addresses the core pathophysiology in many cases: estrogen-progesterone imbalance. Primolutn is flexible to dose, well studied, and often effective within days. It can be used episodically or as part of a longer plan to maintain cyclical control. For patients who cannot or prefer not to use estrogen-containing treatments, norethindrone offers a suitable non-estrogen alternative.

Primolutn for endometriosis symptom control

Endometriosis occurs when endometrial-like tissue grows outside the uterus, commonly causing pelvic pain, dysmenorrhea, and sometimes fertility challenges. Progestins such as norethindrone help by suppressing endometrial proliferation and lowering inflammatory signaling, which can reduce pain and bleeding. Many U.S. guidelines include norethindrone among first-line or adjunctive options for symptom management.

Common approaches include starting with 5 mg twice daily and titrating to 5 mg three times daily as tolerated and as needed for symptom control. Some clinicians prefer continuous therapy without hormone-free intervals to minimize symptom flares. Regular follow-up helps assess pain relief, breakthrough bleeding, tolerability, and whether alternative or adjunct therapies are indicated.

Is Primolutn a contraceptive?

No. The 5 mg norethindrone tablets used with Primolutn-type regimens are not intended or approved as birth control. If you need contraception, discuss suitable options with your clinician. Progestin-only pills for contraception use a much lower dose (0.35 mg daily) taken continuously, and combined estrogen-progestin contraceptives offer additional choices. Primolutn is also not an emergency contraceptive and should not be used for that purpose.

Primolutn for secondary amenorrhea (inducing withdrawal bleeding)

Secondary amenorrhea is the absence of menstruation for three months or more in someone who previously experienced regular periods (or six months for those with prior irregular cycles). Once pregnancy and other causes are excluded, clinicians may use a short course of norethindrone to test for estrogenization and induce a withdrawal bleed. A typical regimen could be 5 mg once or twice daily for 5–10 days. If there is sufficient endogenous estrogen, a withdrawal bleed often occurs within 2–7 days after finishing the course.

This approach can help restore cyclical bleeding while the underlying cause is investigated and addressed. Your clinician will determine whether additional diagnostic testing or long-term cycle management is needed.

Primolutn versus alternatives

Several therapies can address irregular bleeding or endometriosis, and the best option depends on medical history, goals, and tolerability:

• Medroxyprogesterone acetate (e.g., Provera): another commonly used progestin for AUB and amenorrhea.
• Levonorgestrel-releasing IUDs: long-acting local progestin that can markedly reduce bleeding and pain in many patients.
• Combined estrogen-progestin oral contraceptives: suitable for eligible patients needing both cycle control and contraception.
• GnRH analogs: typically reserved for more severe endometriosis when other options are insufficient or not tolerated.
• NSAIDs and tranexamic acid: used as adjuncts for bleeding or pain control where appropriate.

Your clinician will consider risk of blood clots, migraine history, liver function, smoking status, cancer risks, and other personal factors when recommending therapy. Progestin-only approaches like norethindrone are often preferred when estrogen is not suitable.

Mechanism of action

Primolutn (norethindrone) binds to nuclear progesterone receptors in target tissues, transforming the endometrium to a secretory state and making it less prone to unpredictable shedding. It can suppress pituitary gonadotropins (LH and FSH) at sufficient doses, which reduces ovarian steroid production and ovulation in some regimens. In endometriosis, progestin exposure leads to decidualization and atrophy of ectopic endometrial implants, decreasing inflammation and pain.

Because norethindrone does not contain estrogen, it avoids estrogen-related risks, though all systemic hormone therapies warrant individualized risk assessment and monitoring.

Safety profile

Norethindrone has been widely used for decades and is generally well tolerated when appropriately prescribed. Common side effects can include mild nausea, breast tenderness, headache, mood changes, bloating, acne or oily skin, and spotting or breakthrough bleeding, especially during the first cycles. Many symptoms lessen with continued use or dose adjustment.

Serious but less common risks include blood clots (venous thromboembolism), stroke, heart attack, significant changes in liver function, and hypersensitivity reactions. Risk is higher in individuals with a history of clots, certain thrombophilias, heavy smoking (especially age 35 or older), uncontrolled hypertension, and in those immediately postpartum. Although progestin-only regimens generally have a lower thrombotic risk than estrogen-containing therapies, they are not risk-free. Discuss your individual risk profile with your clinician.

Primolutn dosing for adults

Your dose and duration depend on the indication, symptom severity, and medical history. Typical examples (for illustration only; follow your prescription):

• Abnormal uterine bleeding: 5 mg two or three times daily for up to 10 days to control acute bleeding; some patients then continue cyclic therapy (e.g., 5 mg once or twice daily for 10–14 days each cycle).
• Secondary amenorrhea: 5 mg once or twice daily for 5–10 days to induce withdrawal bleeding, as directed.
• Endometriosis: continuous therapy often starts at 5 mg twice daily and may increase to 5 mg three times daily based on response and tolerability.

Swallow tablets whole with water, with or without food, at roughly the same times each day. If you miss a dose, take it when remembered unless it is near the time for your next dose; do not double up. Contact your pharmacist or clinician if you have questions.

Dosing to delay a period (planned menses delay)

Some clinicians prescribe norethindrone to delay a period for travel, athletic events, or personal reasons. A common approach is to start 5 mg two or three times daily about three days before the expected start of menses and continue for the desired length of delay (often up to 10–14 days). A withdrawal bleed typically occurs within 2–4 days after stopping. This approach requires individual assessment; not everyone is a candidate. Discuss your plan and timing with your healthcare professional.

• Use the lowest effective dose for the shortest necessary duration.
• If you experience unexpected heavy bleeding, severe pain, or concerning symptoms, contact your clinician promptly.
• Remember this regimen is not contraception—use a reliable birth control method if pregnancy prevention is desired.

Dosing for heavy or prolonged bleeding

For acute heavy bleeding, clinicians may select a short, higher-frequency regimen of norethindrone (for example, 5 mg three times daily for up to 10 days), with the goal of rapidly stabilizing the endometrium. Once bleeding is controlled, some patients transition to a maintenance or cyclic plan to reduce recurrence. Follow-up evaluation—including ruling out structural causes such as fibroids or polyps—helps guide long-term management.

Take doses at evenly spaced intervals for consistent hormone levels. If you are also prescribed iron for anemia related to blood loss, take it as directed. Report any signs of anemia (fatigue, shortness of breath, pallor) to your clinician.

Endometriosis dosing schedules

Continuous progestin therapy can reduce endometriosis-associated pain by suppressing ovulation and inducing atrophy of endometrial implants. A practical schedule is 5 mg twice daily, increasing to 5 mg three times daily if symptoms persist and the medicine is tolerated. Some patients benefit from long-term continuous therapy, while others use norethindrone intermittently or switch to alternative treatments based on response and side effects.

Keep a symptom diary (pain scores, bleeding days, triggers) to share at follow-up visits. This helps your clinician fine-tune therapy, consider add-back strategies for tolerability, or transition to another modality if needed.

How to take Primolutn

Take Primolutn exactly as prescribed. Consistency matters—aim to take doses at the same time each day. You may take it with food if you experience nausea. Do not stop abruptly without medical advice, particularly if you are using it to control endometriosis symptoms or ongoing bleeding. If you are using norethindrone for recurring cycle regulation, set reminders or use a pill organizer to stay on track.

If you are being treated for heavy menstrual bleeding, your clinician may request follow-up to ensure bleeding control and may order labs (such as a complete blood count) if anemia is suspected. Always keep your care team informed about any other medicines, supplements, or herbal products you are taking.

Pregnancy and breastfeeding

Do not use Primolutn if you are pregnant or trying to conceive unless a clinician has specifically directed its use for a particular medical reason. If you become pregnant while taking norethindrone, stop the medication and contact your clinician. For breastfeeding, low-dose progestin-only contraceptives are generally compatible with lactation; however, higher-dose norethindrone used for AUB or endometriosis may reduce milk supply in some individuals. Discuss risks and alternatives with your pediatrician and obstetrician/gynecologist to choose the safest regimen.

Pharmacist’s tips for taking Primolutn

Take your tablets at consistent times to maintain steady hormone levels. If you experience spotting during the first weeks, this often improves with continued use or minor dose adjustments under clinician guidance. Because Primolutn is not a contraceptive at the 5 mg strength, use a reliable birth control method if pregnancy prevention is important. Before any planned surgery or prolonged immobilization, tell your surgical team that you use a systemic hormone—your clinician may advise holding it beforehand to lower clot risk.

If you have a history of migraines, blood clots, liver disease, certain cancers (such as hormone-sensitive breast cancer), or undiagnosed vaginal bleeding, make sure your clinician knows—these conditions influence whether norethindrone is appropriate. Keep all follow-up appointments and promptly report persistent heavy bleeding, severe headaches, chest pain, shortness of breath, one-sided leg swelling or pain, sudden vision changes, or yellowing of the skin or eyes.

Safety Precautions

Do not take Primolutn if you are allergic to norethindrone or any tablet components; if you are pregnant; if you have active or past blood clots, certain clotting disorders, history of stroke or heart attack, significant liver disease, hormone-sensitive cancers, or unexplained vaginal bleeding. Smoking increases cardiovascular risk with all hormone therapies; avoiding tobacco is strongly recommended. Your clinician will evaluate your individual risk-to-benefit profile before prescribing.

Avoid heavy alcohol consumption, which can affect liver function and overall safety. Use caution if you have migraine with aura, uncontrolled hypertension, diabetes with vascular disease, or strong family history of thromboembolism—discuss these with your clinician.

Primolutn side effects

Like all medicines, Primolutn can cause side effects, though many are mild and improve with continued use. Common effects include:

• nausea or upset stomach
• breast tenderness or fullness
• headache
• mood changes or irritability
• bloating or fluid retention
• acne or oily skin changes
• spotting or breakthrough bleeding, especially initially

Less common but more serious effects that require medical evaluation include:

• signs of a blood clot: swelling, warmth, or pain in one leg; sudden chest pain; shortness of breath
• severe headaches, vision or speech changes, weakness on one side
• yellowing of the skin or eyes, dark urine, or severe abdominal pain (possible liver concerns)
• new breast lumps or nipple changes
• strong allergic reactions: rash, hives, facial swelling, difficulty breathing

Side effects vary by person and dose. Report persistent or severe symptoms to your clinician or pharmacist.

Symptoms to monitor during therapy

During treatment for heavy bleeding or endometriosis, keep track of:

• bleeding pattern and intensity (use a diary or app)
• pelvic pain levels and any triggers
• headaches, mood, or sleep changes
• blood pressure readings if you have hypertension
• any unusual swelling, calf pain, or shortness of breath

Share these details at follow-up to help personalize your therapy.

Reporting side effects

If you experience side effects, contact your clinician or pharmacist. In the United States, you can also report adverse events to the FDA MedWatch program. Immediate medical attention is warranted for signs of allergic reactions, blood clots, severe headaches with neurologic symptoms, or signs of liver injury.

Interaction of Primolutn with other medicines

Norethindrone is metabolized by liver enzymes; certain medicines and supplements can alter its levels or effects. Inform your clinician and pharmacist about all prescription and over-the-counter products you use, including vitamins and herbals. They will help manage or avoid interactions and adjust therapy if needed.

Medicines and supplements that may interact with Primolutn include (not exhaustive):

• enzyme inducers that can reduce effectiveness: rifampin, rifabutin, carbamazepine, phenytoin, phenobarbital, topiramate, and St. John’s wort
• some HIV/HCV therapies that modify hormone metabolism (e.g., ritonavir‑boosted regimens)
• certain antifungals and macrolide antibiotics that may alter levels
• warfarin and other anticoagulants (hormones can affect clotting parameters—monitoring may be needed)
• thyroid medications and corticosteroids (dose adjustments may be required in some cases)

Maintain an up-to-date medication list and share it with every healthcare professional you see. Never start, stop, or change doses without consulting your clinician.
