Exelon side effects and special warnings:

One of the more prominent Exelon side effects is that it has frequently been known to cause nausea and vomiting, especially in the early stages of treatment. This side effect more frequently occurs in women than men and can lead to significant weight loss in both men and women. You should tell your doctor immediately if this side effect occurs.

It has also been observed that the incidence of severe vomiting increases when Exelon is again given after being interrupted for several days. You should not start this medication again after interruption without first consulting with your doctor. Your doctor may actually want to reduce it back to the lowest starting dosage again.

This medication may also aggravate asthma and other problems associated with breathing and can increase the risk of seizures. Similar medications of this type are also known to increase the chance of bleeding, stomach ulcers, and urinary obstruction, although these problems have not been noticed in patients taking Exelon. Medications in this category may also slow down the heartbeat somewhat and sometimes cause fainting in people with heart conditions. Always contact your physician immediately if any of these symptoms occur. This medication has never been tested on children.
