How semaglutide tablet advice differs
The UK Wegovy tablet label recommends contraception during treatment. It reports no clinically relevant change in exposure to the oral contraceptive ingredients studied, ethinylestradiol and levonorgestrel. The label gives no routine instruction to add barrier protection after each dose increase, as some other GLP-1 medicines do.
Other risks to your protection remain. Vomiting, severe diarrhoea, missed contraceptive pills and other interacting medicines all reduce it. Follow the instructions for your contraceptive product and get advice promptly if you are unsure.
Two tablets with different timing rules
Take other oral medicines at least 30 minutes after the Wegovy tablet. If you usually take your contraceptive pill on waking, agree a schedule which keeps your contraception reliable and follows the Wegovy instructions.
Do not move your pill time on a whim if your product has a narrow missed-pill window. Each pill has its own rules. A pharmacist or sexual health clinician will tell you whether a new time needs extra precautions, and will discuss a non-oral method if juggling both tablets is hard.
If your protection may have dropped
Get prompt advice from a pharmacist or sexual health service if you have had sex without reliable protection and think an interaction, a missed pill or vomiting cut your contraceptive cover. Emergency contraception choices are time sensitive and depend on the details.
Tell the clinician the GLP-1 medicine name, dose, the date you started or increased, your contraceptive name, any missed pills and when you had sex. Do not wait for a positive pregnancy test before asking about emergency options. The clinician chooses the emergency method for your situation.
Contraception and pregnancy planning need separate plans
Contraception stops pregnancy during treatment. Planning a pregnancy also needs a set gap after you stop the medicine and, if you have diabetes, a safe replacement plan for your glucose. The washout period differs between medicines.
Changes in weight or in how regular your periods are give no reliable protection. Nor does a belief you are unlikely to conceive because conceiving was hard before. If pregnancy is possible, sort out protection before you start treatment.
Your contraception discussion should be private, practical and based on your own circumstances. The clinician should explain why precautions matter and which options exist, without assuming one method suits everyone. If your first prescribing consultation skipped this, ask a pharmacist or sexual health professional before you rely on an uncertain plan.
Questions for your appointment
Ask how to fit your exact contraceptive product around the Wegovy tablet schedule and what to do if sickness affects it. If you plan a pregnancy, discuss the required gap after stopping semaglutide as a separate topic from day-to-day contraception.
Have your contraceptive product name ready when you ask for advice. Combined pills and the various progestogen-only pills have different missed-pill instructions. Note when you vomited, your last contraceptive dose and any recent missed pills, so the advice fits your real risk.
