Prilosec Side Effects

For people taking Prilosec, side effects that are relatively common include things such as headaches, diarrhea, and dizziness. In most cases, side effects associated with Prilosec are minor, meaning that they require no treatment or may be easily treated. However, you should notify your healthcare provider immediately if you develop more serious side effects, such as depression, fever, or signs of an allergic reaction.

An Introduction to Prilosec Side Effects

As with any medicine, side effects are possible with Prilosec® (omeprazole). However, not everyone who takes the medication will experience side effects. 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 easily treated by you or your healthcare provider.
