Lactinet and Cerazette are commonly discussed as alternatives because they are desogestrel progestogen-only pills in many markets. That makes them closer to brand/generic equivalents than two very different contraceptives, but the exact product leaflet still matters.
Short answer: If both products contain desogestrel 75 micrograms, the expected contraceptive mechanism and missed-pill window are broadly similar. Do not switch brands, start after pregnancy, or use emergency contraception decisions without checking the leaflet or a clinician/pharmacist.
What changed in this update
The comparison now focuses on active ingredient, missed-pill rules, breastfeeding, interactions and warning signs instead of claiming one brand is simply better.

Who should ask before using?
- Current or past breast cancer, severe liver disease, unexplained vaginal bleeding or suspected pregnancy.
- Medicines for epilepsy, tuberculosis, HIV, hepatitis C, or herbal St. John’s wort.
- Recent childbirth, miscarriage or abortion where start timing affects backup contraception.
- Severe vomiting or diarrhea after taking a pill.
Switching brands
Even when the active ingredient matches, packaging, excipients and local instructions can differ. If switching because of side effects, bleeding changes or supply issues, ask whether backup contraception is needed and when to start the new pack.
When to get medical care
Seek urgent medical care for symptoms of severe allergic reaction, severe abdominal pain, sudden chest pain, shortness of breath, sudden severe headache, vision changes, or heavy unexplained vaginal bleeding. Ask a clinician promptly if you may be pregnant or had unprotected sex after missed pills.
FAQ
Are Lactinet and Cerazette the same?
They are often the same active hormone and dose, but always confirm the exact local product leaflet.
Can desogestrel be used while breastfeeding?
NHS and product leaflets generally consider progestogen-only pills compatible with breastfeeding, but individual timing after birth matters.
What if I miss a pill?
Follow the leaflet for your exact pill. Desogestrel POPs commonly use a 12-hour late window and may require backup contraception if missed beyond that.
