Diethylcarbamazine is used in the treatment of certain worm infections. This medicine works by killing the worms. It is used to treat:
Eosinophilic lung (tropical pulmonary eosinophilia; tropical eosinophilia);
River blindness (onchocerciasis).
It will not work for other kinds of worm infections (for example, pinworms or tapeworms).
Diethylcarbamazine is available only with your doctor's prescription, and only from the manufacturer.
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Although there is no specific information comparing use of diethylcarbamazine in children with use in other age groups, this medicine is not expected to cause different side effects or problems in children than it does in adults.
Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information comparing use of diethylcarbamazine in the elderly with use in other age groups.
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
Diethylcarbamazine should be taken immediately after meals.
To help clear up your infection completely, keep taking this medicine for the full time of treatment, even if your symptoms begin to clear up after a few days. In some patients, a second course of this medicine may be required to clear up the infection completely. If you stop taking this medicine too soon, your infection may return. Do not miss any doses.

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.
