Demulen Side Effects

Although most women do not experience any problems with Demulen, negative reactions are possible. Some of the bothersome (but not usually dangerous) side effects of Demulen include bloating, nausea, and breast tenderness. In most cases, these problems are minor and easy to treat. However, you should seek immediate medical care if you experience more serious reactions, such as chest pain, difficulty breathing, or speech changes.

An Introduction to Demulen Side Effects

As with any medicine, Demulen® (ethynodiol diacetate/ethinyl estradiol) can cause side effects. However, not every woman who uses it will experience problems. In fact, most women tolerate it quite well.
If reactions do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider. Many of the common side effects of Demulen may improve within the first few cycles of use.
(Brand-name Demulen is no longer available in the United States, as it was discontinued by its manufacturer. However, generic versions, sold under the names Zovia® and Kelnor™, are still available. If your healthcare provider writes you a prescription for Demulen, your pharmacist will automatically substitute one of the generic versions.)

Common Side Effects of Demulen

Only vague information is available about Demulen side effects. In fact, the side effects listed in the prescribing information for Demulen are actually the possible side effects of all birth control pills in general. Some of the common bothersome (but not usually dangerous) side effects of birth control pills include:
  • Nausea and vomiting
  • Changes in your eyes that make it more difficult to wear contact lenses
  • Bloating
  • Breast tenderness and other breast changes, such as swelling
  • Headaches (although birth control pills can improve headaches in some women)
  • Breakthrough bleeding and spotting between periods
  • Changes in sex drive.
