Dr. Chrysoula I. Liakou MD, PhD
- Treated online: Yes, usually. The progestogen-only pill is prescribed after a video consultation; because it contains no oestrogen, screening rests on a careful history of conditions and medicines rather than measurements.
- What it is: a daily tablet of a progestogen alone, taken every day without breaks; desogestrel types stop ovulation and allow a 12-hour window, while traditional types mainly thicken cervical mucus and allow only a 3-hour window.
- Who it suits: almost everyone the combined pill rules out: migraine with aura, smoking over 35, high blood pressure, a past clot, and the months of breastfeeding.
- Bleeding: irregular bleeding is the commonest reason for stopping the mini pill; about 1 in 5 users stop bleeding altogether, which is safe, and patterns usually settle within 3 months.
- Late pill rules: later than the window: take one pill as soon as you remember, carry on, and use condoms for 48 hours (traditional pill) or 7 days (desogestrel), with emergency contraception if you had sex in the gap.
- Emergency: severe one-sided lower abdominal pain with a late period or positive pregnancy test can signal an ectopic pregnancy: call 112 if you feel faint or the pain is severe.
The progestogen-only pill avoids the clot risks of oestrogen, so most urgent problems are practical rather than dangerous. Two exceptions: severe one-sided lower abdominal pain, especially with a late period or positive pregnancy test, needs emergency assessment (call 112 if you feel faint or the pain is severe), and a new lump in the breast should be examined in person promptly. Missed-pill questions, bleeding changes and everything routine belong in a normal consultation.
How an online consultation helps with the progestogen-only pill
- The right pill when oestrogen is ruled out: If migraine with aura, clot history, blood pressure, smoking or breastfeeding excludes the combined pill, the doctor confirms the progestogen-only pill is the safe alternative and prescribes it in the same call.
- Window rules explained for your actual pill: Three hours or twelve depending on the type; the doctor makes sure you know which one you are holding and what lateness actually means for protection.
- Bleeding expectations set honestly: Irregular bleeding is the mini pill's best-known trade-off. Knowing the odds before you start prevents most of the anxiety afterwards.
- Renewals with a real review: Repeats are issued after a check for new conditions, new medicines and how the bleeding pattern is treating you, not as an automatic reissue.
Can I get the progestogen-only pill prescribed online?
Yes, usually, and it suits online prescribing particularly well: because the progestogen-only pill contains no oestrogen, it has fewer medical exclusions than combined methods, and a careful history covers most of the safety screening.[3] The doctor still checks your history and medicines properly before prescribing.
To renew or switch a pill you already take, you can also start with an Express Assessment for the contraceptive pill: a short online questionnaire that a licensed doctor reviews. If the doctor needs to speak to you, the video call is included.
Who is the progestogen-only pill for?
The progestogen-only pill works for most healthy women, and it is specifically the method of choice when oestrogen is the problem. WHO eligibility criteria leave it open to women with migraine with aura, previous blood clots, raised blood pressure, and smokers over 35, all of whom are excluded from combined hormones, and it can be started early after childbirth and used while breastfeeding.[3] The main conditions that restrict it are current breast cancer, some liver conditions and unexplained vaginal bleeding, which needs investigating before any hormonal method is started. If you are eligible for both pill types, the choice usually turns on bleeding preferences and how you feel about daily timing, and comparing it with the combined pill is a fair part of the consultation.
One naming point, because the internet is untidy about it: progesterone is the natural hormone your body makes; the pill contains a synthetic version called a progestogen (such as desogestrel or levonorgestrel). Progesterone pill, mini pill and POP all describe the same medicine, and your pharmacist will know exactly what the prescription means.
How effective is the progestogen-only pill?
With correct and consistent use the progestogen-only pill is around 99% effective; as commonly used, effectiveness is around 93%, according to WHO figures.[1][5] It works mainly by thickening cervical mucus so sperm cannot pass, and desogestrel types also reliably stop ovulation. It is taken every single day with no breaks between packs, and it does not protect against sexually transmitted infections.
That effectiveness gap is a timing story. The older, traditional progestogen-only pills must be taken within three hours of the same time each day to stay reliable; desogestrel pills allow a twelve-hour window.[2] Twelve hours is forgiving of real life in a way three hours is not, which is why desogestrel types are now the usual first prescription. Whichever you take, anchoring the pill to a fixed daily habit, and knowing the lateness rules below, is what keeps you in the 99% column.
What happens if I take my pill late?
Late means more than three hours after your usual time for traditional pills, or more than twelve hours for desogestrel types.[2] If that happens: take a pill as soon as you remember (just one, even if you missed more), take the next at the usual time, and use condoms for the next 48 hours with a traditional pill, or 7 days with a desogestrel pill.[4] If you had sex after the late pill and before protection was re-established, contact a doctor promptly about emergency contraception. Vomiting within about two hours of taking a pill, or severe diarrhoea, counts as a missed pill and follows the same rules. These rules are the entire difference between the mini pill working and not, so they are worth keeping somewhere you can find at midnight.
Which situation is yours?
This is the decision framework the doctors use in progestogen-only pill consultations:
Swipe sideways to compare →
| Your situation | Likely first step | Suitable for online care? | When referral or in-person care is needed |
|---|---|---|---|
| Cannot take oestrogen: migraine with aura, clot history, raised blood pressure, or smoker over 35 | Progestogen-only pill prescribed after history review | Usually yes | Raised blood pressure also deserves its own follow-up |
| Breastfeeding, or recently gave birth | Progestogen-only pill, usable from early after birth | Usually yes | Only if other postnatal concerns need examination |
| Struggles with strict timing, or shift work scrambles routine | Desogestrel type with its 12-hour window, or a patch, ring or implant conversation | Yes | Implant and IUD fittings are in person |
| On the mini pill with irregular or prolonged bleeding | Structured review: reassurance, a switch, or investigation depending on pattern | Often yes | Bleeding after sex, between periods persistently, or after 45 warrants examination |
| Unexplained vaginal bleeding not yet assessed, or current breast cancer | Investigation before any hormonal contraception | No, assessment first | In-person examination and investigation come first |

The consultation is shorter than a combined-pill screening, but it is a real one:
- Why this pill: whether you are choosing the mini pill or being steered to it by a condition that excludes oestrogen, because that changes the alternatives worth mentioning.
- Breast cancer history: current breast cancer rules out hormonal contraception, and a past history needs a careful, individualised discussion.[3]
- Unexplained bleeding: bleeding that has not been assessed gets investigated before a pill masks the pattern.
- Liver conditions: significant liver disease restricts hormonal methods.
- Interacting medicines: enzyme-inducing drugs, including some epilepsy and tuberculosis treatments and St John's Wort, can stop the progestogen-only pill working; users of these medicines are advised towards methods the interaction cannot touch.[2]
- Ectopic pregnancy history: relevant background for a method that does not always block ovulation, so warning symptoms are explained clearly.
- Your daily rhythm: work pattern, time zones and honesty about routine, which decides whether a 3-hour pill, a 12-hour pill or a non-daily method is the realistic recommendation.
- Bleeding tolerance: how you would feel about spotting, irregularity or absent periods, the trade-off question that predicts satisfaction better than any other.
Side effects, honestly
The defining trade-off is bleeding: on the progestogen-only pill some women bleed less or not at all (safe, and often welcome), some carry on much as before, and some get irregular spotting or more frequent bleeding, which is the most common reason for stopping.[2] Patterns often settle over the first three months, so the fair trial is three packs, not three weeks. Other reported effects include breast tenderness, headaches, mood changes and acne, usually mild and often temporary. What the mini pill does not carry is oestrogen's blood clot risk, which is precisely why it stays available to women with cardiovascular risk factors.[3] Periods and fertility return quickly after stopping; there is no lasting effect to wait out. Because ovulation is not always suppressed, a pregnancy that does occur has a somewhat higher chance of being ectopic, which is why one-sided pain with a late period is on the urgent list, not the wait-and-see list.
Treatment options
What you can do yourself
Anchor the pill to a fixed daily habit at an hour that survives your worst days, not your best ones: many people choose a morning routine over a bedtime that varies. Set a phone alarm anyway. Keep the missed-pill rules saved on your phone, carry a spare strip when travelling, and when crossing time zones keep dosing to roughly the same 24-hour rhythm rather than switching abruptly to local time. Track any bleeding changes for the first three months before judging the method. And because no pill protects against infections, condoms stay in the picture with new or untested partners.
Prescription treatment
A doctor never issues a prescription without a consultation. When the history is clear, the doctor usually prescribes a desogestrel-type pill for its twelve-hour window, or a traditional type, depending on what suits or what's available. Started on days one to five of your period, it protects immediately; started at any other time, it needs 48 hours of condoms alongside.[2][4] Switching from the combined pill is timed so protection never lapses, usually by starting the mini pill the day after an active combined pill with no break. Renewals are issued online after a review of new conditions, medicines and bleeding pattern, and most women settle into a quick annual check.
When the progestogen-only pill is prescribed online, and when you need in-person care
The doctor prescribes online: first starts and switches, including the common move from combined hormones when aura, blood pressure, smoking, age or breastfeeding changes the calculus; renewals with a genuine review; a switch between mini pill types when bleeding or timing windows are the problem; and a planned move to the patch, ring or combined pill when screening allows and you want a different routine.
In-person care: unexplained vaginal bleeding is investigated before any hormonal method is started or continued; current breast cancer means hormonal contraception is not prescribed at all; persistent bleeding between periods, bleeding after sex or new bleeding patterns after 45 are examined rather than explained away; a new breast lump is examined in person promptly; and possible ectopic symptoms, one-sided pain with a late period, go to emergency care, not a video queue.
When to get in-person care
Call 112 or go to an emergency department for severe one-sided lower abdominal pain, especially with a late period, a positive pregnancy test, shoulder-tip pain or feeling faint: these can be signs of an ectopic pregnancy. See a doctor in person promptly for a new breast lump, yellowing of the skin or eyes, or vaginal bleeding that is persistent, heavy or follows sex.

Frequently asked questions about the mini pill
What is the progestogen-only pill, and how does it work?
The progestogen-only pill (mini pill) is a daily contraceptive tablet containing a progestogen and no oestrogen, taken every day without a break. Desogestrel-type pills work mainly by stopping the ovaries releasing an egg; traditional types work mainly by thickening the mucus at the neck of the womb so sperm cannot pass, and thinning the womb lining. Both are over 99% effective when taken on time.
What is the difference between the mini pill and the combined pill?
The combined pill contains oestrogen and a progestogen and is taken with breaks or dummy pills; the mini pill contains a progestogen only and is taken every day without breaks. The mini pill avoids oestrogen's clot risk, which keeps it available to women with migraine with aura, smokers over 35 and those who are breastfeeding, at the cost of less predictable bleeding and, for traditional types, a stricter timing window.
How effective is the progestogen-only pill?
Taken on time every day, the progestogen-only pill is over 99% effective. As commonly used, with late or missed pills, it is about 93%, the same as the combined pill. Desogestrel types are more forgiving because they stop ovulation and allow a 12-hour window; traditional types allow only three hours. It gives no protection against sexually transmitted infections.
Can I get the progestogen-only pill prescribed online in Europe?
Yes, after a consultation; a prescription is never issued without one. Because the mini pill contains no oestrogen, screening rests on a careful history of conditions and medicines rather than measurements, which online consultations handle well, and the prescription is sent to a pharmacy near you for a first supply, a switch or a repeat.
Who should not take the mini pill?
The progestogen-only pill is not suitable for women with current breast cancer, unexplained vaginal bleeding, severe liver disease, or who take medicines that reduce its effect, such as some epilepsy, tuberculosis and HIV treatments. A previous ectopic pregnancy and ovarian cysts are discussed rather than ruling it out. Almost everyone excluded from the combined pill can take the mini pill.
How late can I take my pill before it stops working?
Traditional progestogen-only pills allow three hours beyond your usual time; desogestrel types allow twelve. Later than that: take one pill as soon as you remember, carry on as normal, use condoms for 48 hours with a traditional pill or seven days with desogestrel, and consider emergency contraception if you had sex before the pill was back on track. Vomiting within two hours counts as a missed pill.
When does the mini pill start working?
Start the progestogen-only pill on days one to five of your period and you are protected straight away. Start at any other time and use condoms for the first two days (48 hours). When switching from the combined pill, start the day after your last active pill with no break and you remain protected; the doctor explains the switch from other methods.
Is it normal for my periods to change on the mini pill?
Yes, and it is the trade-off to expect: periods on the progestogen-only pill may become lighter, irregular, more frequent or stop altogether. Absent periods on this pill are safe. Patterns usually settle within three months; bleeding that stays heavy, follows sex or keeps recurring after that deserves a review to exclude infection or other causes.
What are the side effects of the progestogen-only pill?
Apart from bleeding changes, side effects of the mini pill are usually mild and settle in the first months: breast tenderness, headaches, acne, mood changes, nausea and small ovarian cysts that resolve on their own. It carries no oestrogen-related clot risk, does not affect blood pressure, and has no lasting effect on fertility; ovulation returns within days of stopping.
Does the mini pill cause weight gain?
Research has not shown a consistent effect of the progestogen-only pill on weight, though individual experiences vary and deserve discussion rather than dismissal. If your weight changes noticeably after starting, raise it at a review; there is usually more than one explanation, and switching to another method is simple if you want to test the link.
Can I take the progestogen-only pill while breastfeeding?
Yes. The progestogen-only pill is a standard choice while breastfeeding and can be started early after childbirth, from day 21 without extra precautions. It does not affect milk supply, and the tiny amounts of hormone involved are not considered harmful to the baby, which is why it is preferred over the combined pill in the first months.
What if I take antibiotics or other medicines with the mini pill?
Common antibiotics do not reduce the progestogen-only pill's effectiveness. The medicines that do are enzyme inducers: rifampicin and rifabutin, some epilepsy medicines, some HIV treatments and St John's wort; while taking these, and for four weeks after, a different method such as the coil or injection is advised. Tell the doctor about every medicine and supplement at the consultation.
