Introvale is a type of oral contraceptive that works primarily by stopping ovulation. However, it also enables women to have a period only four times a year. Although most women tolerate it well, side effects are possible and may include nausea, vomiting, and breakthrough bleeding, among other things. This birth control pill is taken once a day, preferably at the same time each day.
Introvale™ (levonorgestrel/ethinyl estradiol) is a generic birth control pill. It is equivalent to Seasonale®. As an "extended-cycle" oral contraceptive, you will get your period once every three months (only four times a year) with this product.

As with any medicine, side effects are possible with Introvale. However, not everyone who uses the contraceptive will experience problems. In fact, most people tolerate it quite well.
If side effects do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider. Serious reactions are less common.
Common side effects seen with Introvale include but are not limited to:
- Breakthrough bleeding or spotting between periods
- Breast tenderness
