What Are the Possible Side Effects Associated With Imuran Therapy?

Side effects of Imuran may include:

  • Increased stomach irritation.
  • Nausea and vomiting.
  • Changes in hair color and texture along with hair loss -- these changes are usually temporary.
  • Loss of appetite.
  • Blood in the urine or stool.
  • Unusual bruising.
  • Fatigue.
  • Development of mouth sores and ulcers.
  • Liver damage.
  • Increased risk of infection. Because Imuran is an immunosuppressive medication, it can lower the number of white blood cells in your blood, increasing the chance of infection.

It's important to remember that not everyone experiences all of these side effects. This medication is generally well-tolerated. Even though some of the side effects could be very serious, remember that precautions will be taken to detect these side effects and treat them before they become harmful.

What Should I Do If I Forget to Take a Dose of Imuran?

If you forget to take a dose of Imuran, take it as soon as you remember and then continue to follow your regular dosing schedule.

How Should I Store Imuran?

  • Store Imuran at room temperature.
  • DO NOT store this medication in direct heat or light.
  • DO NOT store this medication in the bathroom, near the kitchen sink, or in other damp places. Heat or moisture may cause it to break down.
  • Keep this drug in the container it came in, tightly sealed.
  • Do not keep outdated medicine.
  • Keep this and other drugs out of the reach of children
