The patch and ring deliver the same two hormones (progestin plus estrogen) on the same 3-weeks-on, 1-week-off rhythm with the same 7% typical-use failure rate; they differ in how you wear them.
The patch is a weekly skin sticker for the lower abdomen, buttocks, or upper body, changed once a week for 3 weeks. The ring is placed in the vagina for 3 weeks, removed for the period week, then replaced. That makes the real decision about weekly versus monthly tasks and about comfort: the patch is visible and can peel with sweat, swimming, or skin irritation; the ring is invisible but requires being comfortable inserting and removing it. Both are prescription methods, both carry the estrogen-class cautions (notably higher clot risk for smokers over 35), and neither protects against STIs. If you like seeing your birth control and a weekly cue, the patch fits. If you want one task a month and nothing visible, the ring fits. Missed changes on either one weaken protection, so set phone reminders for swap days.
What to do
Common questions
What is the difference between the patch and the ring?
The patch and the ring are near-identical hormonally: both release progestin plus estrogen, both run a 3-weeks-on, 1-week-off cycle with a period in the off week, and both carry a 7% typical-use failure rate, the same as the pill. What differs is the delivery and the schedule. The patch sticks to skin on your lower abdomen, buttocks, or upper body (never the breasts) and you swap it once a week for 3 weeks. The ring is a flexible plastic ring you place inside your vagina yourself, leave for 3 weeks, remove for your period week, then replace. So the choice is weekly remembering with a visible sticker versus monthly remembering with an internal device. Practical trade-offs: the patch can loosen with sweat, swimming, or friction, shows on skin, and some people get skin irritation; the ring cannot be seen, but you have to be comfortable placing and removing it, and some users or partners notice it during sex (it can be removed for up to a few hours without losing protection, per its labeling). Both are prescription-only, both share the pill's estrogen-related cautions like clot risk in smokers over 35, and neither protects against STIs. Pick the patch if you want visible confirmation and weekly rhythm; pick the ring if you want the fewest tasks per month.
