SIDE EFFECTS

Patch side effects

    WILL THE PATCH AFFECT MY PERIODS?expand_less

    The patch may cause disrupted periods, either in the form of irregular bleeding (spotting or breakthrough bleeding), or regular, lighter periods. During the first few cycles of using the patch, bleeding between periods (breakthrough bleeding) and spotting (very light, irregular bleeding) is common.

    The contraceptive patch may cause some women to gain weight.

    Like other forms of hormonal birth control, the contraceptive patch may cause you to experience mood swings.

    Acne can be a side effect of using the contraceptive patch. However, some women may find that their acne improves whilst using combined hormonal contraceptives like the patch.
