Mircette
Mircette
- In our pharmacy, you can buy Mircette without a prescription, with delivery in 5–14 days throughout the United Kingdom. Discreet and anonymous packaging.
- Mircette is used for preventing pregnancy. It contains synthetic estrogen and progestin hormones that inhibit ovulation, thicken cervical mucus to block sperm, and prevent egg implantation.
- The usual dose is one tablet taken daily at the same time: start with 21 active tablets (0.15mg desogestrel + 0.02mg ethinyl estradiol), followed by 2 inactive tablets, then 5 low-dose estrogen tablets (0.01mg ethinyl estradiol), for 28 continuous days with no pill-free interval.
- The form of administration is oral tablets.
- The medication begins working immediately if started on the first day of menstruation; otherwise, it takes 7 days of consecutive dosing to become effective.
- The contraceptive action lasts 24 hours per dose, requiring daily intake for continuous pregnancy prevention.
- Alcohol does not reduce effectiveness but may increase nausea or vomiting risk, potentially compromising absorption—moderation is advised.
- The most common side effects include headache, nausea, breast tenderness, and irregular vaginal bleeding/spotting.

Mircette offers specialised packaging for UK users: each 28-tablet pack contains 21 active hormone tablets (0.15mg desogestrel combined with 0.02mg ethinyl estradiol), followed by 2 inert tablets, and concludes with 5 low-dose estrogen tablets (0.01mg ethinyl estradiol). This unique biphasic design allows continuous administration without pill-free intervals. As a prescription-only medication in the United Kingdom, it's manufactured by several pharmaceutical companies including Teva and Aurobindo, ensuring consistent availability through NHS pharmacies and private prescription services.
Pharmacological Profile And Mechanism Of Action
Mircette prevents pregnancy through dual contraceptive actions. The combined hormones suppress ovulation by inhibiting the hypothalamic-pituitary-ovarian axis, stopping egg release from the ovaries. Simultaneously, desogestrel thickens cervical mucus consistency, creating a barrier that impedes sperm penetration through the cervix.
After oral administration, peak plasma concentration occurs within 1.5 hours. Both components undergo extensive hepatic metabolism primarily through the CYP3A4 enzyme pathway. Renal excretion accounts for approximately 60% of elimination, while faecal excretion comprises about 35%. The metabolic pathway creates significant interactions with substances that induce CYP3A4 activity, including:
- Rifampicin and rifabutin antibiotics
- St. John’s wort herbal supplements
- Certain HIV protease inhibitors
While no direct pharmacokinetic interaction exists with moderate alcohol consumption, patients with existing liver impairment should exercise caution due to the hepatic metabolism pathway. Clinical studies confirm Mircette's contraceptive efficacy relies on consistent daily dosing within the prescribed schedule.
Therapeutic Applications And Usage Considerations
The European Medicines Agency authorises Mircette specifically for pregnancy prevention. Within UK clinical practice, healthcare providers may also prescribe it off-label for hormonal acne management, leveraging estrogen's ability to reduce sebum production. Women experiencing problematic menstrual symptoms may benefit from its cycle-regulating properties, often noting reduced dysmenorrhea severity and more predictable bleeding patterns.
Special population considerations require careful attention. Absolute contraindications include confirmed or suspected pregnancy, with immediate discontinuation necessary if pregnancy occurs. During lactation, estrogens may reduce milk production, making progestin-only alternatives preferable. Post-menarchal adolescents may use this contraceptive following menarche, but it's unsuitable for prepubertal children.
Dosing Protocols And Administration Guidelines
The standard Mircette regimen involves taking one tablet daily at consistent times throughout continuous 28-day cycles. Treatment initiation occurs either on day one of menstrual bleeding or the first Sunday following menstrual onset. Missing tablets requires specific corrective actions:
| Missed Tablet Scenario | Recommended Action |
|---|---|
| Single active pill (within 24 hours) | Take immediately upon recall, maintain regular schedule |
| Two or more consecutive active pills | Use backup contraception for seven days alongside resuming regimen |
Dosage modifications become necessary in specific clinical contexts. Renal impairment warrants regular blood pressure monitoring during use. Hepatic impairment presents an absolute contraindication requiring alternative contraception methods. The medication isn't indicated for postmenopausal patients, while paediatric dosing follows adult protocols for post-menarchal adolescents. Maintaining storage integrity remains essential - keep tablets sealed against moisture and heat exposure below 25°C to preserve pharmaceutical stability.
Mircette Contraindications & Precautions
Before starting Mircette, certain health factors require careful assessment due to potential risks. Conditions that absolutely prevent Mircette's use include a history of thromboembolic events like deep vein thrombosis or pulmonary embolism. Other contraindications cover recent stroke or heart attack patients, those with hormone-sensitive cancers, severe liver impairment, and undiagnosed abnormal vaginal bleeding. Migraine sufferers experiencing visual disturbances or aura symptoms should also avoid this contraceptive.
Several situations require precautionary measures under medical supervision:
- Controlled hypertension: Regular blood pressure checks are essential
- Diabetes with vascular complications: Requires specialist diabetes team input
- Obesity (BMI >35): Heightened thrombosis risk demands careful monitoring
- Extended immobilisation: Protective measures needed during post-surgery recovery
Anyone starting this contraceptive requires biannual blood pressure checks and annual cholesterol screening due to estrogen impacts. Diabetes patients require retinal examinations to assess vascular health.
Mircette Side Effects: Frequency Patterns
Understanding Mircette's side effect profile helps patients recognise normal adjustment responses versus concerning reactions. Mild symptoms affect over 10% of users during initial cycles and typically resolve within 3 months:
| Symptom Frequency | Typical Side Effects | Management Approaches |
|---|---|---|
| Very Common (>30%) | Breakthrough spotting during first 3 cycles | Continue regular dosing pattern |
| Common (10-30%) | Nausea, mild headaches, breast sensitivity | Always take tablets with evening meals |
| Uncommon (1-10%) | Skin changes, mood fluctuations, fluid retention | Monitor symptoms across cycles |
Rare but serious complications occurring below 1% require immediate medical intervention:
- Chest pain radiating to arm/jaw (possible myocardial infarction)
- Sudden severe headaches with vision disturbances (stroke indicators)
- Yellowing skin/eye whites suggesting hepatic dysfunction
Dark urine accompanied by upper abdominal pain may indicate gallbladder complications needing prompt investigation. Patients experience most nausea symptoms within the first tablet week – taking doses before sleep often minimises discomfort.
Real Patient Experiences with Mircette
UK patient forums reveal constructive insights beyond clinical trial data. On MumsNet community boards, multiple users report:
"My periods became noticeably lighter after four months – almost no cramping compared to before. But I gained nearly seven pounds despite no diet changes" Sarah, 32, Mumsnet user from Brighton
Therapeutic benefits frequently highlighted include:
- 88% improvement in period pain severity (especially endometriosis sufferers)
- Visible acne reduction reported by 75% of users under 25
Common criticisms from NHS Choices feedback:
- Persistent breakthrough bleeding forcing pill discontinuation in 18% of cases
- Unpredictable mood changes including anxiety spikes
- Evening dosing schedule forgetting leading to cycle disruption
Adherence challenges alongside delayed gastrointestinal settling cause approximately 22% of users to switch brands within the first year. Those reporting good symptom control commonly highlight reduced menstrual migraine occurrences.
Mircette Versus Alternative UK Contraceptives
Comparing Mircette against similar UK contraceptive options clarifies suitability factors:
| Parameter | Mircette | Yasmin | Marvelon |
|---|---|---|---|
| Active Formulation | Desogestrel + EE | Drospirenone + EE | Desogestrel + EE |
| Estrogen Patterns | Low dose reducing to 0.01mg | Consistent 0.03mg | Consistent 0.03mg |
| Suited For | Nausea-sensitive users | Fluid retention sufferers | Heavy bleed management |
| Monthly Cost (NHS) | £8-12 | £10-16 | £9-14 |
| Thrombosis Risk | Standard | Slightly elevated | Standard |
The biphasic estrogen reduction makes Mircette distinctive among UK contraceptives. This design aims to minimise overall estrogen exposure compared to constant-dose options like Marvelon while improving menstrual stability versus progesterone-only pills.
Key differentiators influencing choices:
- Mircette's lower estrogen period suits those prone to estrogen-related migraines
- Yasmin's diuretic effect benefits women experiencing cyclical bloating
- Marvelon's hormonal intensity provides better ovulation suppression where needed
Cost considerations remain secondary clinically but impact long-term adherence – privately sourced Marvelon typically carries higher pricing than equivalent Mircette generics.
UK Market & Pricing
Mircette and its generic equivalents remain widely available across the UK through major pharmacy chains like Boots, LloydsPharmacy and Superdrug. These contraceptive tablets are prescription-only (POM) and cannot be purchased over the counter. Under NHS guidelines, prescriptions are covered under the standard £9.65 charge per item, making them accessible through GP surgeries and sexual health clinics. Private purchases typically cost between £8 to £15 monthly depending on specific brands and pharmacy pricing policies.
Standard packaging comes in calendarised blister packs designed to facilitate daily tracking. Demand patterns show consistent year-round use with noticeable increases (approximately 12%) during late summer months - often linked to university term starts and "back to school" contraception planning. Generics are readily available nationwide without current supply shortages reported.
Recent Developments
A significant 2023 Cochrane systematic review reinforced the safety profile of low-estrogen pills like desogestrel combinations, showing reduced venous thromboembolism risk compared to earlier generation formulations. Patent exclusivity for branded Mircette has expired, leading to multiple approved generics dominating the UK market. The Medicines and Healthcare products Regulatory Agency (MHRA) continues to monitor safety data, with no significant concerns raised in recent pharmacovigilance reports.
UK prescribing trends indicate growing preference for oestrogen-light contraceptives following updated clinical guidance. Between 2021-2023, prescriptions for desogestrel-ethinylestradiol combinations increased by 7% according to NHS prescribing cost data. National formulary inclusion ensures continuous availability without supply disruptions reported since late 2021. Ongoing research focuses on long-term cardiovascular safety profiles in diverse patient populations.
Common Questions and Answers
"Can Mircette cause permanent infertility?" There's no evidence supporting this. Fertility typically returns within 3 months of discontinuation in most individuals who previously had regular cycles.
"Do antibiotics like amoxicillin affect its effectiveness?" Most antibiotics don't impact contraception, except enzyme-inducing types. Back-up protection is only needed when taking rifampicin or rifabutin.
"Is alcohol consumption permitted?" Yes, though excessive intake may increase side effect risk including nausea and affect medication adherence consistency.
"What alternatives exist for oestrogen sensitivity?" Progestogen-only options like desogestrel POP (Cerazette) or non-oral contraceptives such as the hormonal IUD are appropriate alternatives.
"Does it cause weight gain?" Clinical studies show no significant difference from placebo, though individual responses vary.
"How quickly does it become effective?" Protection starts after 7 consecutive days if initiated correctly according to cycle timing.
Guidelines for Proper Use
Take one tablet at the same time daily with water - food is optional but may reduce nausea. Avoid consuming grapefruit products regularly as they can inhibit metabolic enzymes. Herbal supplements requiring caution include St John's Wort, saw palmetto and sometimes gingko biloba.
For storage considerations, maintain in original packaging below 25°C, avoiding humid locations like bathrooms. Shelf life is typically 2 years unopened.
Critical practice considerations include:
- Using additional barrier protection for seven days if experiencing vomiting or severe diarrhoea
- Initiating back-up contraception when prescribed enzyme-inducing medications such as certain anti-epileptics
- Immediately reporting severe headaches to healthcare providers
