Hormonal Therapy Comparison Tool
Choose Your Situation
This tool helps you identify the most appropriate hormonal therapy based on your primary condition and personal preferences.
Key Takeaways
- Aygestin (norethindrone) is a low‑dose progestin used for menstrual disorders, endometriosis and contraception.
- Levonorgestrel, medroxyprogesterone acetate and drospirenone are the most common alternatives, each with a distinct side‑effect profile.
- Choose based on indication, dosing convenience, metabolic impact and personal tolerance.
- Switching requires a wash‑out period only for estrogen‑containing combos; progestin‑only switches are usually seamless.
- Regular monitoring of bleeding patterns and hormone levels helps fine‑tune therapy.
What is Aygestin (Norethindrone)?
When you see Aygestin is a synthetic progestin (norethindrone) available in 0.35 mg and 5 mg tablets. It was first approved by the FDA in 1965 and has become a staple for treating endometriosis, abnormal uterine bleeding, and for hormone‑replacement therapy in post‑menopausal women.
The 0.35 mg dose is typically prescribed for menstrual regulation, while the 5 mg dose tackles the heavier symptoms of endometriosis. Because the hormone is a 19‑nor‑testosterone derivative, it binds strongly to progesterone receptors but has minimal androgenic activity, which translates to fewer skin‑related side effects for many users.
How Aygestin Works
Aygestin suppresses the growth of the endometrial lining by mimicking the natural luteal phase of the menstrual cycle. This inhibition reduces menstrual flow, eases pelvic pain, and can even shrink endometriotic implants over several months.
Its half‑life is about 8‑10 hours, meaning steady daily dosing maintains a consistent serum level. Unlike combined oral contraceptives, Aygestin does not contain estrogen, so it avoids estrogen‑related risks such as clot formation but also lacks the cycle‑stabilizing benefits estrogen provides.
Common Alternatives Overview
When doctors talk about “alternatives,” they usually mean other progestins or combined therapies that achieve similar goals. Below are the three most frequently considered options.
Levonorgestrel is a second‑generation progestin found in many emergency‑contraception pills and low‑dose IUDs. It has a longer half‑life (around 24 hours) and stronger androgenic effects, which can cause acne or hirsutism in sensitive patients.
Medroxyprogesterone acetate (MPA) is the active ingredient in Depo‑Provera injections. The depot formulation provides three‑month coverage, making adherence easy, but it can raise bone‑density concerns with long‑term use.
Drospirenone is a newer progestin that carries anti‑mineralocorticoid activity, helping reduce water retention. It’s often paired with estradiol in combined pills (e.g., Yaz) and is praised for its low androgenic profile.
Other notable entities that pop up in the discussion include Estradiol, the primary estrogen used in many combined regimens, and Progestin, the broader class of synthetic progesterone molecules.

When to Choose Aygestin vs Alternatives
If your primary goal is to shrink endometriotic lesions without adding estrogen, Aygestin is the clear front‑runner. Its low‑dose version lets you fine‑tune bleeding without the risk of estrogen‑driven clotting.
Levonorgestrel shines when you need a quick, high‑dose burst-think emergency contraception-or a long‑lasting IUD that releases the drug directly into the uterine cavity. The trade‑off is a higher chance of androgenic side effects.
Medroxyprogesterone acetate becomes attractive for patients who struggle with daily pill adherence. A quarterly injection removes the forget‑factor, but you must watch bone health, especially if you’re under 40.
Drospirenone is the best bet for women who want combined contraception but are sensitive to water retention or acne. Its anti‑mineralocorticoid action counteracts bloating, while the paired estradiol smooths the cycle.
In practice, the decision often boils down to three questions:
- Is estrogen needed for your condition? (e.g., menopausal symptoms vs pure progestin therapy)
- How important is dosing convenience? (daily pill vs injection vs IUD)
- Do you have a history of androgen‑sensitive side effects?
Answering these guides you toward the right column in the table above.
Practical Tips for Switching Therapies
- Consult your clinician before stopping any hormone; abrupt withdrawal can cause rebound bleeding.
- If moving from Aygestin to a combined pill, start the new regimen on the first day of your next period to minimize overlap.
- For injection‑based switches (e.g., to Depo‑Provera), schedule the shot at least 7 days after your last Aygestin dose.
- Track your symptoms in a simple spreadsheet: note bleeding days, pain scores, and any new side effects. This data helps your doctor fine‑tune the dose.
- Consider a baseline bone‑density scan if you’ll be on medroxyprogesterone acetate longer than a year.
Frequently Asked Questions
Can I use Aygestin as a regular birth control pill?
Aygestin’s low‑dose 0.35 mg formulation can prevent ovulation in some women, but it’s not as reliable as combined contraceptives. Doctors generally reserve it for menstrual regulation rather than primary contraception.
What should I expect after switching from Aygestin to a levonorgestrel IUD?
Most patients experience lighter periods within three months. You might have spotting for the first few weeks as the uterus adjusts. Because the IUD releases levonorgestrel locally, systemic side effects are usually milder than oral pills.
Is there a risk of weight gain with Aygestin?
Weight gain is not a common side effect of norethindrone. If you notice changes, discuss them with your doctor; other factors like diet or concurrent medications could be at play.
How long does it take for Aygestin to reduce endometriosis pain?
Most studies report noticeable pain relief after 8-12 weeks of daily 5 mg dosing. Full lesion shrinkage may require 6 months of continuous therapy.
Can I take Aygestin while breastfeeding?
Low‑dose norethindrone is considered compatible with breastfeeding, as only minimal amounts pass into milk. However, always confirm with your pediatrician.
Bottom Line
Choosing the right hormonal therapy hinges on your specific condition, lifestyle, and how your body reacts to each progestin. Aygestin offers a low‑dose, estrogen‑free route excellent for endometriosis and irregular bleeding. Levonorgestrel, medroxyprogesterone acetate, and drospirenone each bring unique strengths-whether it’s convenience, combined cycle control, or reduced water retention. Use the comparison table and the practical checklist to discuss options with your clinician and arrive at a plan that fits your life.

October 25, 2025 AT 14:12The comparison table nails the basic pharmacology, yet it skips the gritty reality of patient adherence. While the half‑life data is crystal clear, the daily pill burden of Aygestin can be a deal‑breaker for many. A 0.35 mg tablet still demands a strict routine, something an IUD or injection sidesteps. The article also downplays the cost differences that often drive prescription choices. Insurance formularies can make a massive impact on whether a provider pushes levonorgestrel or norethindrone. Moreover, the bone‑density warnings for medroxyprogesterone acetate deserve more emphasis, especially for younger women. In short, the side‑effect profiles are only half the story; practical logistics matter just as much.

October 29, 2025 AT 15:25Don’t be fooled by pharma propaganda; they push combined pills to control women. The government and big pharma hide the true benefits of low‑dose progestins. Keep an eye out for hidden agendas.

November 1, 2025 AT 12:52I see the table and I can’t help but think about how every choice reflects a deeper philosophy of health. Aygestin, with its low dose and estrogen‑free profile, appeals to those who want a minimalist approach to hormone modulation. It respects the body’s own rhythm without the added clot risk that estrogen brings. Yet the same minimalism can feel like a gamble when patients crave the cycle‑stabilizing comfort of combined pills. The trade‑off between simplicity and perceived completeness is a classic tension. Levonorgestrel offers a powerful burst for emergency needs, but its androgenic side effects remind us that potency often comes with a price. Medroxyprogesterone’s injectable convenience is seductive, yet the long‑acting nature can mask subtle bone density loss over time. Drospirenone’s anti‑mineralocorticoid action seems almost futuristic, but the need for estradiol pairing re‑introduces estrogen’s double‑edged sword. When you step back, the pattern emerges: each molecule is a compromise shaped by lifestyle, symptom priority, and risk tolerance. The decision matrix isn’t just a spreadsheet; it’s a conversation between a patient’s daily habits and their long‑term health goals. For someone who can’t remember a daily pill, the injection wins. For a teen worried about acne, the low‑androgen profile of drospirenone shines. For a post‑menopausal woman fearing bone loss, the neutral impact of norethindrone is comforting. The article mentions monitoring bleeding patterns, and that is crucial because patterns reveal how the body truly accepts the hormone. Keep a symptom diary, track pain scores, and note any mood swings; data will guide the clinician better than any table. Ultimately, the best therapy is the one that fits seamlessly into life while keeping side effects at bay.

November 9, 2025 AT 01:25i gotta say the guide is super useful but also kinda confusing lol aygestin sounds like a fancy word for micro‑dose but real life ain’t that easy the daily pill can slip your mind especially when you’re busy with work and kids also the side effects list is legit but i’ve heard people say they got extra pimples from levonorgestrel which kinda matches the table also don’t forget that injections like depo can be a pain if you ain’t into shots i think the best move is to talk to your doc and maybe keep a simple log of bleed days and mood changes it helps a lot.

November 18, 2025 AT 21:32For anyone deciding between these options remember three practical points first check if you need estrogen second consider how often you want to take medication third think about any history of acne or bone loss. Aygestin works well for endometriosis without estrogen risks but requires daily dosing. Levonorgestrel is great for quick contraception and IUD use with a longer half‑life. Medroxyprogesterone acetate offers a quarterly shot, which helps compliance yet may affect bone density over time. Drospirenone combined with estradiol can reduce water retention but adds estrogen to the mix. Discuss these factors with your clinician and track your symptoms to fine‑tune the plan.
