How To Use Lizinna
Complete Step-by-Step Usage Guide, Dosage Instructions & Safety Information
Key Takeaways: How to Use Lizinna
- Standard regimen: One tablet daily for 21 days, then a 7‑day pill‑free break. A withdrawal bleed usually occurs during the break.
- Starting: Begin on day 1 of your period for immediate protection. If starting later, use extra contraception (condoms) for the first 7 days.
- Missed pills: If less than 24 hours late, take it immediately. If more than 24 hours late, follow the missed pill rules (see Dosage Guide) and use extra protection for 7 days.
- Vomiting/diarrhoea: If you vomit within 2‑3 hours of taking a pill, take another from a spare strip. If severe diarrhoea lasts more than 24 hours, follow missed pill advice.
- Contraindications: Do not use if you have a history of blood clots, liver disease, certain migraines, or breast cancer. Not recommended during breastfeeding.
Lizinna is a combined oral contraceptive pill that must be taken correctly to ensure maximum effectiveness. This guide explains exactly how to take Lizinna, what to do if you miss a pill, and important safety information.
Important Medical Advice
If you have missed pills and do not have a withdrawal bleed during the first pill‑free break, you may be pregnant. Do a pregnancy test or see your doctor. Also seek immediate medical help if you experience symptoms of a blood clot (sudden chest pain, breathlessness, leg swelling), severe headache, or yellowing of skin/eyes.
How to Take Lizinna: Step-by-Step Usage Guide
Follow these steps precisely to maintain contraceptive protection.
- Starting your first pack: If you start on day 1 of your menstrual period (first day of bleeding), you are protected immediately. If you start on any other day, use an extra barrier method (e.g., condoms) for the first 7 days.
- Daily intake: Take one tablet every day, at approximately the same time. Swallow the tablet whole with water. It can be taken with or without food, but consistency in timing is crucial.
- 21‑day course: Continue taking one tablet daily for 21 consecutive days. Each blister strip contains 21 tablets.
- 7‑day break: After finishing the 21 tablets, you have a 7‑day pill‑free break. During this week you will usually have a withdrawal bleed similar to a period, starting 2‑3 days after the last pill.
- Next pack: Start your next pack on the same day of the week as your first pack, exactly 7 days after your last pill, even if you are still bleeding. This ensures continuous contraceptive cover.
🗒️ Tip: Set a daily alarm or use a pill reminder app to help you take your pill at the same time every day.
Dosage Guide: When to Start and What to Do in Special Situations
Starting Lizinna
- Natural cycle (day 1 start): Immediate protection. No extra contraception needed.
- Natural cycle (day 2‑5 start): Protection is immediate only if you start on day 2‑5 and use extra contraception for the first 7 days. Many clinicians still advise 7 days of condoms.
- After childbirth or miscarriage: Your doctor will advise when to start. Usually, if you are not breastfeeding, you can start 21‑28 days after delivery.
- Switching from another pill: Follow the specific switching instructions; generally, you can start the next day without a break.
Missed Pill Rules (based on PIL)
| Scenario | Action | Extra protection needed? |
|---|---|---|
| Less than 24 hours late | Take it immediately, then continue at usual time. | No |
| More than 24 hours late (1 or 2 pills) | Take the last missed pill (even if it means taking two in one day), continue the pack. If you missed 2 pills, take the most recent missed one and discard the earlier one. | Yes, for 7 days |
| More than 24 hours late (3 or more pills) | Stop current pack, start a new pack the next day (no break). | Yes, for 7 days; consider emergency contraception if you had unprotected sex. |
| Missed pills in week 3 (days 15‑21) | Finish the pack, then start the next pack immediately without a 7‑day break. | Yes, for 7 days |
Vomiting and Diarrhoea
If you vomit within 2‑3 hours of taking a pill, take another pill from a spare strip immediately (as if you missed one). If vomiting or severe diarrhoea continues for more than 24 hours, follow the missed pill rules for the days you were ill. Use extra contraception during and for 7 days after recovery.
Who Should Use Lizinna and Who Should Not
Lizinna is suitable for: Women of reproductive age who want reliable, reversible contraception and have no contraindications to combined hormonal contraceptives.
Contraindications (Do NOT use Lizinna if you):
- Have or have had a blood clot in a vein (DVT) or artery (heart attack, stroke).
- Have a condition that increases clot risk (e.g., thrombophilia, major surgery with prolonged immobilisation).
- Have ever had migraine with aura.
- Have current or past breast cancer or other hormone‑sensitive cancer.
- Have severe liver disease (e.g., liver tumour, active hepatitis) or unexplained vaginal bleeding.
- Are pregnant (or suspect pregnancy).

Always discuss your full medical history with a doctor or nurse before starting Lizinna.
Taking Lizinna with Food or Without Food
Lizinna can be taken with or without food. There is no significant food interaction that affects its absorption. However, taking it with a meal may help some women avoid mild nausea, which can occur during the first few cycles.
Key point: Consistency in timing is far more important than whether you take it with food. Choose a routine that suits you and stick to it.
If you vomit shortly after taking the pill (within 2‑3 hours), follow the missed pill instructions above, as the dose may not have been fully absorbed.
Special Conditions: Pregnancy, Breastfeeding, and Other Considerations
Pregnancy
Lizinna is contraindicated during pregnancy. If you become pregnant while taking Lizinna, stop immediately and consult your doctor. Epidemiological studies have not shown an increased risk of birth defects when combined pills are inadvertently taken in early pregnancy, but the pill is not indicated for use during pregnancy.
Breastfeeding
Combined oral contraceptives like Lizinna are generally not recommended during breastfeeding because oestrogen may reduce milk production and quality. Progestogen‑only pills (POP) are preferred. Discuss with your healthcare provider.
Drug Interactions
Certain medicines can reduce Lizinna's effectiveness by increasing the metabolism of ethinylestradiol. These include:
- Rifampicin, rifabutin (antibiotics)
- Some anticonvulsants (phenytoin, carbamazepine, topiramate)
- Certain HIV medications (protease inhibitors, NNRTIs)
- St John’s Wort (herbal remedy)
If you take any of these, you may need alternative contraception or additional barrier methods. Always inform your doctor of all medicines you take.
Liver Impairment
Lizinna is contraindicated in severe liver disease. In mild impairment, use with caution and medical supervision.
Age and Smoking
Women over 35 who smoke are at increased risk of cardiovascular side effects and are generally advised not to use combined pills. Discuss with your doctor.
Lizinna FAQs
Can I take Lizinna while breastfeeding?
Combined pills like Lizinna are not usually recommended during breastfeeding because oestrogen can reduce milk supply. A progestogen‑only pill (mini‑pill) may be a better option. Consult your doctor.
What should I do if I miss two pills in a row?
Take the most recent missed pill immediately (discard the earlier one), continue the pack, and use extra contraception (condoms) for the next 7 days. If you missed pills in week 3, finish the pack and start the next pack without a break.
Does diarrhoea affect Lizinna's effectiveness?
Severe diarrhoea lasting more than 24 hours may reduce absorption. Treat it like missed pills: continue taking your pills but use extra contraception during and for 7 days after recovery. If diarrhoea is very severe, consult your doctor.
Can I delay my period with Lizinna?
Yes. To delay a period, finish your current pack and start the next pack immediately the next day, skipping the 7‑day break. You may have some breakthrough bleeding, but protection continues. After 21 days, take a 7‑day break as usual.
How long do I need to use extra protection when starting Lizinna?
If you start on day 1 of your period, no extra protection is needed. If you start at any other time, use condoms or abstain for the first 7 days of pill‑taking.
