Quick answer
- Same hormones as the combined pill, different delivery.

- Over 99% perfect use, 91% typical.
- Some medicines can make them less effective.
The ring and the patch both release oestrogen and progestogen, just like the combined pill. They’re over 99% effective used perfectly and 91% with typical use. Fertility usually returns within 1 to 3 months of stopping.
The ring
- A soft, flexible ring about 5cm across that you put in your vagina – a bit like a tampon
- Leave it in for 21 days, then take a 7-day break
- You shouldn’t be able to feel it, including during sex
- Started on days 1–5 of your period: protected straight away
The patch
- A 5cm square sticker on clean, dry skin – arm, back, bottom or tummy
- New patch every 7 days for 3 weeks, then a patch-free week
- Not affected by vomiting (unless it comes off)
- Started on days 1–5 of your period: protected straight away
