Side Effects of Hydroxychloroquine
Possible Side Effects of Hydroxychloroquine
For recently approved medications, very specific information about side effects is available. However, for older medications (such as hydroxychloroquine), the prescribing information provides only vague side effect information. Based on this information, possible bothersome (but usually not dangerous) side effects of hydroxychloroquine may include:
- Nausea and vomiting
- Diarrhea and abdominal pain
- Dizziness or a spinning sensation (vertigo)
- Ringing in the ears (tinnitus)
- Loss of appetite
- Irritability or nervousness
- Hair loss or bleaching of the hair
- Sensitivity to the sun
- Weight loss
- Changes in skin pigment (either a loss of pigment or a blue-black pigment).
It is possible that you may experience some or none of the side effects of hydroxychloroquine listed in this article. Unfortunately, there is no way for your healthcare provider to know beforehand if you will have side effects from a medicine that you have never tried. Therefore, make sure to let your healthcare provider know if you develop any side effects while taking hydroxychloroquine or if something "just does not seem right." While it may not be a side effect of hydroxychloroquine, your healthcare provider will be able to diagnose and treat the problem.
