Quick Answer — What is Yasmin?
- Yasmin is a combined oral contraceptive pill containing drospirenone 3 mg + ethinylestradiol 30 mcg, manufactured by Bayer.
- Taken one tablet daily for 21 days followed by a 7-day pill-free break — over 99% effective with perfect use.
- Drospirenone is the unique ingredient: it has mild anti-androgen + anti-mineralocorticoid activity, which is why Yasmin tends to feel “lighter” on bloating, breast tenderness and acne than older pills.
- Most often chosen by women who want contraception plus some acne and PMS relief — without the strong anti-androgen profile of Diane-35.
- Available at MedsBase as branded Bayer Yasmin — no prescription needed. WHO-GMP certified manufacturing. Worldwide Shipping.
What Is Yasmin?
Yasmin is a combined oral contraceptive (COC) — it contains both a synthetic oestrogen and a synthetic progestogen in every tablet. The composition is:
- Drospirenone 3 mg — a fourth-generation progestogen derived from spironolactone
- Ethinylestradiol 30 mcg (0.03 mg) — a standard-strength oestrogen
Bayer markets Yasmin globally and licences it to Bayer India for regional production. The pack is a 21-tablet blister; all 21 tablets are active (no placebo / sugar pills). Yaz, sold by the same manufacturer, uses the same drospirenone 3 mg but pairs it with a lower 20 mcg dose of ethinylestradiol — and ships as a 24-active / 4-placebo 28-tablet pack. Both are described in detail on the Yasmin product page and the Yaz product page.
How Does Yasmin Work?
Like all combined pills, Yasmin prevents pregnancy through three overlapping mechanisms:
- Suppression of ovulation — the combination of oestrogen and progestogen flattens the LH and FSH surge that would normally trigger ovulation. No egg is released.
- Thickening of cervical mucus — progestogen makes the mucus at the cervix much harder for sperm to swim through.
- Endometrial thinning — the uterine lining becomes less hospitable to implantation as a back-up if ovulation slipped through.
What makes drospirenone unusual among progestogens is its receptor profile. It is a weak androgen-receptor antagonist (so it does the opposite of testosterone in tissues that affect skin and hair) and a mineralocorticoid-receptor antagonist (so it counters aldosterone-driven water retention). Older pill progestogens like levonorgestrel are mildly androgenic and tend to cause some acne, hair shedding and water retention; drospirenone tends to do the reverse. That is the entire reason Yasmin exists as a separate brand.
Who Is Yasmin Best For?
- Women who want reliable contraception and noticeable improvement in mild hormonal acne or oily skin
- Women whose previous pill (levonorgestrel-based, e.g. Microgynon, Loette, Ovral-L) caused breast tenderness, bloating or premenstrual mood swings
- Women with PMDD (premenstrual dysphoric disorder) — Yaz, the lower-EE sister, has the strongest evidence here but Yasmin is also routinely used
- Women who want predictable monthly bleeding — Yasmin’s 21+7 cycle produces a clear, scheduled withdrawal bleed each month
How to Take Yasmin
The standard regimen for Yasmin is straightforward:
- Start on day 1 of your period — contraceptive cover begins immediately. (If you start on days 2-5, use condoms for the first 7 days.)
- Take one tablet daily at roughly the same time each day for 21 days.
- Take a 7-day pill-free break. A withdrawal bleed will start during this break, usually around day 2-4.
- Start the next 21-day pack on day 8 of the break, whether or not the bleed has stopped. The day-of-week always stays the same across cycles.
Contraceptive cover is maintained during the 7-day break provided you took every pill in the previous pack correctly and you restart the next pack on time. The break is not a “rest from protection” — it is the planned hormone dip that triggers the bleed.
What If You Miss a Pill?
Yasmin’s missed-pill rule is the same as other 30-mcg combined pills:
- Less than 24 hours late (i.e. you remembered before the next scheduled dose) — take the missed pill as soon as you remember, continue the pack as normal. No back-up needed.
- More than 24 hours late, or two or more pills missed — take the most recent missed pill straight away, skip earlier missed pills, continue the pack, and use condoms for the next 7 days. If the missed pills were in week 1, consider emergency contraception (see the i-pill (levonorgestrel) or Postpone 72 product pages). If they were in week 3, finish the active pills and skip the 7-day break entirely — start the next pack immediately.
Yasmin Side Effects
Most women tolerate Yasmin well, particularly after a one- to three-month settling-in period. Common side effects in the first 1-3 cycles include:
- Breakthrough bleeding or spotting — usually resolves by cycle 3
- Nausea — taking the pill with food or at bedtime usually solves this
- Breast tenderness — typically mild, eases after the first cycle
- Mild headache — distinct from migraine; persistent or worsening headache warrants a clinical review
- Mood changes — both improvements (less PMS) and lows are reported; if mood worsens persistently, switch pill type
- Reduced libido — uncommon but possible with any drospirenone product
Stop Yasmin and seek urgent care if you develop any of the following:
- Sudden severe leg pain or swelling (possible deep vein thrombosis)
- Sudden chest pain or breathlessness (possible pulmonary embolism)
- Sudden visual loss, slurred speech or one-sided weakness (possible stroke)
- Severe abdominal pain with jaundice (rare hepatic effect)
- Aura-pattern migraine starting for the first time
Combined hormonal contraceptives slightly raise venous thromboembolism (VTE) risk. The absolute risk on Yasmin is roughly 9-12 cases per 10,000 women per year, versus 5-7 per 10,000 on levonorgestrel pills and 2 per 10,000 in non-users. The risk is highest in the first 3 months and falls thereafter. Smoking, age over 35, BMI over 30, recent surgery and known thrombophilia all stack with this baseline — discuss any of these before starting.
Yasmin vs Yaz vs Diane-35 vs Standard Combined Pill
The four most-asked-about combined pills at MedsBase are all “estrogen + progestogen” — but the progestogen choice (and to a lesser extent the EE dose) changes how the pill feels day-to-day.
| Pill | Progestogen | EE dose | Anti-androgen activity | Best for |
|---|---|---|---|---|
| Yasmin | Drospirenone 3 mg | 30 mcg | Mild | Contraception + mild acne, bloating, PMS |
| Yaz | Drospirenone 3 mg | 20 mcg | Mild | As Yasmin, lower EE for oestrogen-sensitive users; PMDD evidence |
| Diane-35 | Cyproterone acetate 2 mg | 35 mcg | Strong | Moderate-to-severe hormonal acne, hirsutism, PCOS |
| Loette / Ovral-L | Levonorgestrel | 20-30 mcg | None / mildly androgenic | Lowest VTE risk profile; can worsen acne |
| Femilon | Desogestrel 0.15 mg | 20 mcg | Minimal | Lower-EE alternative if oestrogen side effects on Yasmin are a problem |
If you do not tolerate oestrogen at all (migraine with aura, age 35+ with smoking, BMI > 35, history of VTE), the combined pill is the wrong category and a progestogen-only pill like Cerazette (desogestrel) is the safer route. There’s a fuller side-by-side in Birth Control Methods Compared.
Drospirenone — the Reason People Choose Yasmin
Drospirenone was developed in the 1980s and entered the contraceptive market in 2000 specifically to address the “lifestyle” side effects of older pills. Three pharmacological properties matter:
- Anti-mineralocorticoid effect — drospirenone is a spirolactone derivative and partially blocks aldosterone, slightly reducing fluid retention. Translation: less bloating, less breast tenderness, no creeping weight gain in the first cycle.
- Anti-androgenic effect — drospirenone binds the androgen receptor weakly as an antagonist. It is far less potent than cyproterone (the active in Diane-35), but it still nudges acne and oily skin in the right direction in mild cases. Severe acne or hirsutism is still better served by Diane-35 or by adding a topical such as birth-control-for-acne combinations, or by stacking a topical retinoid alongside (see tretinoin + niacinamide for the standard layering protocol).
- Neutral-to-favourable lipid profile — drospirenone does not worsen LDL/HDL in the way some older progestogens do.
The trade-off is the slightly higher VTE risk discussed in the red box above. For a healthy non-smoker under 35 with no family history of clotting, the absolute risk remains very small — and well below the VTE risk of pregnancy itself.
Who Should Not Take Yasmin
Yasmin is contraindicated (do not start) if any of the following apply:
- History of venous or arterial thrombosis (DVT, PE, stroke, heart attack)
- Known thrombophilia (Factor V Leiden, protein C/S deficiency, antiphospholipid antibodies)
- Migraine with aura at any age
- Age 35+ and current smoker
- BMI > 35
- Uncontrolled hypertension (≥160/100), or controlled hypertension on multiple agents
- Severe renal impairment — drospirenone raises serum potassium; in normal kidneys this is clinically insignificant, but with eGFR < 30 it matters
- Known or suspected breast cancer, undiagnosed vaginal bleeding, active liver disease, or known pregnancy
- Currently taking strong CYP3A4 inducers — rifampicin, rifabutin, carbamazepine, phenytoin, St John’s wort — which reduce pill efficacy
How to Switch From Another Pill to Yasmin
Three common scenarios:
- From another 21+7 combined pill (Loette, Ovral-L, Microgynon, etc.): finish your current pack, take the 7-day break as usual, then start Yasmin on day 8 (the day you would normally have started your next pack). No extra cover needed.
- From a 28-day combined pill (Yaz, Triquilar, Ovral-G, etc.): finish the active tablets, skip any placebo / iron pills, and start Yasmin the next day. No extra cover needed.
- From a progestogen-only pill (Cerazette, etc.): start Yasmin on any day and use condoms for the first 7 days of the new pack.
If you are switching because of side effects, give the new pill at least two full cycles before judging — the first 1-2 months of any pill change involves a settling-in period that is not representative of the pill’s long-term feel.
Drug Interactions
The combined-pill drug-interaction list is long, but the clinically meaningful ones are:
- Strong enzyme inducers (rifampicin, rifabutin, carbamazepine, phenytoin, phenobarbital, St John’s wort, some HIV antiretrovirals): substantially reduce EE and drospirenone levels. Use condoms throughout and for 28 days after stopping.
- Lamotrigine: combined pills lower lamotrigine levels — seizure breakthrough is possible. Coordinate with your neurology team.
- Potassium-sparing diuretics and ACE inhibitors: theoretically additive on potassium; check potassium if combining long-term or in renal impairment.
- Antibiotics (general): most do not reduce pill efficacy. The old “use condoms with any antibiotic” advice has been retired — only the enzyme-inducing antibiotics rifampicin and rifabutin matter. If antibiotic-related vomiting or diarrhoea happens within 4 hours of taking the pill, treat that pill as missed.

Frequently Asked Questions
Is Yasmin the same as Yaz?
Almost. Both are Bayer-manufactured drospirenone pills. Yasmin pairs drospirenone 3 mg with ethinylestradiol 30 mcg in a 21-active-tablet pack; Yaz pairs the same 3 mg of drospirenone with a lower 20 mcg of EE in a 24-active + 4-placebo 28-tablet pack. The lower oestrogen dose in Yaz makes it slightly gentler on oestrogen-related side effects (breast tenderness, nausea, headache) at the cost of slightly more breakthrough bleeding. Yaz also carries the strongest evidence base for PMDD.
How effective is Yasmin?
With perfect use (no missed pills, no enzyme-inducer interaction, on-time pack restart): >99%. With typical use (real-world adherence): around 91-93% — almost all failures are attributable to missed pills or late pack restart, not pill failure itself.
Will Yasmin help my acne?
For mild hormonal acne — yes, often noticeably within 2-3 months. For moderate-to-severe hormonal acne, hirsutism, or PCOS-driven skin symptoms, Diane-35 is the stronger anti-androgen pill. Yasmin is also commonly stacked with a topical retinoid (see our tretinoin + niacinamide guide) for faster results without escalating to oral anti-androgens.
Does Yasmin cause weight gain?
Randomised trials of drospirenone pills have not shown a meaningful weight gain signal. Many women report less bloating-related apparent weight gain than on older pills, because drospirenone’s anti-mineralocorticoid effect reduces water retention. Any genuine fat gain on Yasmin is usually attributable to other lifestyle factors and will not respond to switching pills.
Can I skip my Yasmin withdrawal bleed?
Yes — Yasmin is suitable for “tricycling” (running three packs back to back, then taking the 7-day break) or continuous use. There is no clinical need for the monthly bleed; the original 21+7 schedule is a historical design choice, not a medical requirement. Skipping bleeds is safe but may cause more breakthrough spotting in the first 2-3 extended cycles.
What happens if I vomit after taking Yasmin?
If you vomit within 4 hours of taking a pill, treat that pill as missed: take another active tablet from a spare pack (or take the next tablet immediately), then continue the pack on schedule. Use condoms for the next 7 days if you cannot replace the dose.
Does Yasmin expire?
Yes — every Yasmin blister carries an expiry date on the foil and outer carton. Stored at room temperature (15-30°C) and out of direct sunlight, blister-packed Yasmin retains full potency until the printed expiry. More detail on storage and shelf life of all combined pills is in our does birth control expire? guide.
Can I take Yasmin while breastfeeding?
Combined pills are generally not recommended in the first 6 weeks postpartum because of VTE risk, and oestrogen can reduce milk supply. The progestogen-only pill Cerazette is the standard substitute during breastfeeding. Switch back to Yasmin once you’ve stopped breastfeeding, if desired.
Is Yasmin available at MedsBase without a prescription?
Yes. MedsBase ships genuine Bayer Yasmin (drospirenone 3 mg + ethinylestradiol 30 mcg) in the original 21-tablet blister, with no prescription needed. Multi-pack discounts are available — see the Yasmin product page for current pricing across 21, 42, 63 and 126-tablet bundles.
Where can I read more about choosing between pills?
