Sronyx Side Effects

As with any medicine, side effects are possible with Sronyx. However, not everyone who uses the contraceptive will experience side effects. In fact, most people tolerate it quite well.

  • Breast swelling and tenderness
  • Acne
  • Nausea with or without vomiting
  • Breakthrough bleeding or spotting (between periods)
