Side Effects of Diethylpropion

Possible Side Effects of Diethylpropion

Diethylpropion has been studied thoroughly in clinical trials. In these studies, the side effects that occur in a group of people taking the drug are documented and are then compared to side effects that occur in another group of people not taking the medicine. This way, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine. With newer medications, information about the exact percentage of these side effects is available. However, with older medications (such as diethylpropion), these percentages are not available.
In studies, diethylpropion side effects included:
  • Blurred vision
  • Hyperactivity, nervousness, restlessness, or jitteriness
  • Dizziness
  • Insomnia (see Tenuate and Insomnia)
  • Unusual happy feelings (euphoria) or unusual unpleasant feelings (dysphoria)
  • Shakiness (tremor)
  • Dilated (wide-open) pupils
  • Drowsiness
  • A general ill feeling (malaise)
  • Headache
  • Nausea and vomiting
  • Diarrhea, constipation, or abdominal pain (stomach pain)
  • Dry mouth or unpleasant taste
  • Impotence (erectile dysfunction or ED)
  • Changes in sex drive
  • Menstrual changes
  • Increased sweating
  • Hair loss.

Final Thoughts on Side Effects of Diethylpropion

You may experience some or none of the side effects of diethylpropion listed in this article. Unfortunately, it can be difficult to tell if any particular side effect (such as nausea) is actually caused by diethylpropion or other factors. Therefore, make sure to let your healthcare provider know if you develop any side effects while taking the drug or if something "just does not seem right." While it may not be a side effect of diethylpropion, your healthcare provider will be able to diagnose and treat the problem.
