What is Twirla?

Twirla patches contain a combination of two female hormones, ethinyl estradiol and levonorgestrel.

Twirla is a prescription medicine used as birth control to prevent pregnancy.

Twirla is for use by women with a BMI less than 30 kg/m2 who can become pregnant. Twirla patches have been shown to have reduced effectiveness in women with a BMI in the range 25 to 30 kg/m2.
