Talwin Nx Side Effects

Even though many people taking Talwin Nx will tolerate the medicine well, tell your healthcare provider right away if you develop depression, an urge to take more Talwin Nx than prescribed, or other potentially serious reactions. Other possible side effects of Talwin Nx include nausea, vomiting, and diarrhea.

An Introduction to Talwin Nx Side Effects

Just like any medicine, Talwin® Nx (pentazocine/naloxone) can cause side effects. However, not everyone who takes the medication will have problems. In fact, most people tolerate it quite well. If reactions 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 Talwin Nx. Your healthcare provider can discuss a more complete list with you.)

Common Side Effects of Talwin Nx

For many medications, the prescribing information carefully details the exact percentage of side effects that were observed in clinical trials.

  • Nausea
  • Vomiting
  • Sedation
  • Constipation
