Menopause Home > Premphase Side Effects
Although most women have no problems with Premphase, side effects can occur. The drug has been known to cause several side effects, such as headaches, breast pain, and stomach pain. This medication can also cause serious side effects. Contact your healthcare provider right away if you develop serious side effects of Premphase, such as chest pain, vision changes, or breast lumps.
An Introduction to Premphase Side EffectsAs with any medicine, side effects are possible with Premphase® (conjugated estrogens/cyclic medroxyprogesterone). However, not everyone who takes the drug will experience side effects. In fact, most women tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are easily treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Premphase. Your healthcare provider can discuss a more complete list of Premphase side effects with you.)
