Xeomin Side Effects

If you are receiving Xeomin injections, contact your healthcare provider immediately if you develop any signs that the toxin is spreading, such as loss of bladder control, double vision, or difficulty swallowing. In most cases, however, reactions to this product tend to be mild and easy to treat. Some of the most commonly reported side effects of Xeomin include infections, headaches, and muscle pain.

An Introduction to Xeomin Side Effects

Just like any medicine, Xeomin® (incobotulinumtoxinA) can cause side effects. However, not everyone who receives the medication will have problems. 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 treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Xeomin. Your healthcare provider can discuss a more complete list with you.)

Common Side Effects of Xeomin

Xeomin has been studied extensively in clinical trials. In these studies, the side effects that occurred in a group of people given Xeomin were documented and compared to those that occurred in a similar group of people given a placebo (an injection that did not contain any active ingredients). As a result, it was possible to see what side effects occurred, how often they appeared, and how they compared to the group receiving the placebo.
In studies of Xeomin for cosmetic use (to improve the appearance of lines between the eyebrows), the only common side effect was headaches, which occurred in 5.4 percent of people who received Xeomin, compared to 2.2 percent of people who received the placebo. All other side effects occurred in less than 1 percent of people.
In studies of Xeomin for treating cervical dystonia (a condition involving muscle spasms of the head and neck), the most common side effects included:
  • Difficulty swallowing -- in up to 18 percent of people
  • Neck pain -- up to 15 percent
  • Any infection -- up to 13 percent
  • Muscle weakness -- up to 11 percent
  • Muscle pain -- up to 4 percent
  • Pain at the injection site -- up to 4 percent.
In studies of Xeomin for blepharospasm (eyelid spasms), the most common side effects included:
  • Any type of infection -- in up to 20 percent of people
  • Droopy eyelids -- up to 19 percent
  • Dry eyes -- up to 16 percent
  • Dry mouth -- up to 16 percent
  • Vision problems -- up to 12 percent
