Twirla is indicated for use by women of reproductive potential as a method of contraception to prevent pregnancy.
Twirla releases estrogen and progestin hormones through the skin. These hormones work by suppressing ovulation and thickening cervical mucus to help prevent sperm from reaching an egg.
Twirla should not be used by women who smoke and are over 35 years old due to increased risk of serious cardiovascular events. The patch is applied once weekly for three consecutive weeks, followed by a patch-free week. Women with risk factors for blood clots, stroke, or certain cancers should discuss their medical history with a healthcare provider before use. Effectiveness may be reduced in women with certain weights.
