Nuedexta Side Effects
Contact your healthcare provider right away if you are taking Nuedexta and develop potentially serious problems, such as seizures, loss of vision or hearing, or difficulty breathing. In most cases, however, people tolerate the medication quite well and any problems that occur are typically easy to treat. Common side effects of Nuedexta include diarrhea, dizziness, and coughing.
Just like any medicine, Nuedexta™ (dextromethorphan and quinidine) can cause side effects. However, not everyone who takes 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 Nuedexta. Your healthcare provider can discuss a more complete list with you.)
Nuedexta has been studied extensively in clinical trials. In these studies, one group of people received the real medication, while another group was given a placebo (a "sugar pill" that does 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 placebo.
In these studies, the most commonly reported Nuedexta side effects included:
- Diarrhea -- in up to 13 percent of people
- Dizziness -- up to 10 percent
- Coughing -- up to 5 percent
- Vomiting -- up to 5 percent
- Weakness -- up to 5 percent
- Swelling of the legs, ankles, or feet -- up to 5 percent
- Urinary tract infection (UTI) -- up to 4 percent
- Flu -- up to 4 percent
- Elevated liver enzymes -- up to 3 percent
- Gassiness -- up to 3 percent.
