The most common side effects of Twirla include: skin reactions at the patch site, nausea, headache, menstrual cramps and/or weight gain. These are not all of the possible side effects of Twirla.
The chances of serious side effects are rare. Like pregnancy, hormonal birth control may increase the risk of serious blood clots especially in women who have risk factors, such as smoking, high blood pressure, high levels of cholesterol in the blood, diabetes, obesity, a family history of blood clots or are older than 35 years old. These may sound scary, but remember — those side effects are rare.
