FDA Issues New Warning About Using Malaria Drug Qualaquin to Treat or Prevent Nighttime Leg Cramps

FDA's Advice on Qualaquin

The FDA offers this advice for consumers:

  • If you take Qualaquin for nighttime leg cramps, discuss other treatment options with your doctor.
  • Contact your doctor immediately if you experience easy bruising, severe nose bleeding, blood in your urine or stools, bleeding gums, or the appearance of unusual purple, brown, or red spots on the skin.
  • Read the medication guide provide by the pharmacy when you pick up a prescription for Qualaquin.
  • Report any side effects to the MedWatch Adverse Event Reporting Program.

The FDA says the medication guide spells out what Qualaquin is approved and not approved for, as well as its potential side effects.

The FDA had previously warned Americans in late 2006 not to use quinine for leg cramps. It said then that it had received 665 reports of serious adverse events linked to quinine, including 93 deaths.
