Question 1

How soon after starting Zoely am I protected against pregnancy?

Accepted Answer

If you start on the first day of your period, you are protected immediately. If you start on days 2‑5 of your cycle, use condoms for the first 7 days. After that, protection is continuous.

Question 2

Does Zoely work during the 4 placebo tablets?

Accepted Answer

Yes. The 4‑day hormone‑free interval is too short for ovulation to resume, provided you took all active tablets correctly. You remain protected during the placebo days.

Question 3

How long does Zoely stay in your system after you stop taking it?

Accepted Answer

Nomegestrol acetate has a half‑life of ~46 hours, so it takes about 10 days to be fully eliminated. Estradiol clears in about 3‑4 days. Most women ovulate within 2‑4 weeks after stopping.

Question 4

Can antibiotics make Zoely less effective?

Accepted Answer

Most antibiotics (except rifampicin and rifabutin) do not affect Zoely. Rifampicin, used for tuberculosis, strongly induces liver enzymes and can reduce efficacy – extra contraception is needed during and for 28 days after.

Question 5

How long does it take for Zoely to suppress ovulation?

Accepted Answer

Ovulation is suppressed within the first cycle of correct use. With a day‑1 start, suppression begins immediately. With a days‑2‑5 start, it takes 7 days to achieve full follicular suppression.
