Precautions

Drug information provided by: Merative, Micromedex®

If your symptoms do not improve within a few days, or if they become worse, check with your doctor.

For patients taking diethylcarbamazine for river blindness:

  • It is important that your doctor check your progress at regular visits. This is to help make sure that the infection is cleared up completely. Also, your doctor may want you to have your eyes checked by an ophthalmologist (eye doctor).
  • Diethylcarbamazine may cause loss of vision, night blindness, or tunnel vision with prolonged use. This medicine may also cause some people to become dizzy. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert or able to see well. If these reactions are especially bothersome, check with your doctor.
  • Doctors may also prescribe a corticosteroid (a cortisone-like medicine) for certain patients with river blindness, especially those with severe symptoms. This is to help reduce the inflammation caused by the death of the worms. If your doctor prescribes these two medicines together, it is important to take the corticosteroid along with diethylcarbamazine. Take them exactly as directed by your doctor. Do not miss any doses.
