ARALEN

Take this medicine with meals or milk to lessen stomach upset, unless otherwise directed by your doctor.

Keep this medicine out of the reach of children. Children are especially sensitive to the effects of chloroquine and overdose is especially dangerous in children. Taking as little as 1 tablet (300-mg strength) has resulted in the death of a small child.

It is very important that you take this medicine only as directed. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. To do so may increase the chance of serious side effects.

If you are taking this medicine to help keep you from getting malaria, keep taking it for the full time of treatment. If you already have malaria, you should still keep taking this medicine for the full time of treatment even if you begin to feel better after a few days. This will help to clear up your infection completely. If you stop taking this medicine too soon, your symptoms may return.

Chloroquine works best when you take it on a regular schedule. For example, if you are to take it once a week to prevent malaria, it is best to take it on the same day each week. Or if you are to take two doses a day, one dose may be taken with breakfast and the other with the evening meal. Make sure that you do not miss any doses. If you have any questions about this, check with your health care professional.

For patients taking chloroquine to prevent malaria :

• Your doctor may want you to start taking this medicine 1 to 2 weeks before you travel to an area where there is a chance of getting malaria. This will help you to see how you react to the medicine. Also, it will allow time for your doctor to change to another medicine if you have a reaction to this medicine.
• Also, you should keep taking this medicine while you are in the area and for 4 weeks after you leave the area. No medicine will protect you completely from malaria. However, to protect you as completely as possible, it is important to keep taking this medicine for the full time your doctor ordered. Also, if fever develops during your travels or within 2 months after you leave the area, check with your doctor immediately .

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 chloroquine, the following should be considered:

Allergies Tell your doctor if you have ever had any unusual or allergic reaction to chloroquine or hydroxychloroquine. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.

Pregnancy Unless you are taking chloroquine to treat malaria or liver disease caused by protozoa, use of this medicine is not recommended during pregnancy. In animal studies, chloroquine has been shown to cause damage to the central nervous system (brain and spinal cord) of the fetus, including damage to hearing, sense of balance, bleeding inside the eyes, and other eye problems. However, when given in low doses (once a week) to prevent malaria, this medicine has not been shown to cause birth defects or other problems in humans.

Breast-feeding Chloroquine passes into breast milk. Chloroquine has not been reported to cause problems in nursing babies. However, babies and children are especially sensitive to the effects of chloroquine. The amount in breast milk is not enough to prevent the infant from getting malaria.

Children Children are especially sensitive to the effects of chloroquine. This may increase the chance of side effects during treatment. Overdose is especially dangerous in children. Taking as little as 1 tablet (300-mg strength) has resulted in the death of a small child. Children should avoid traveling to areas where there is a chance of getting malaria, unless they can take antimalarial medicines that are more effective than chloroquine.

Older 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 chloroquine in the elderly with use in other age groups.

Other medicines 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. When you are taking chloroquine, it is especially important that your health care professional know if you are taking the following:

• Mefloquine (e.g., Lariam) Use of chloroquine with mefloquine may increase the chance of convulsions (seizures)

• Blood disease (severe) Chloroquine may cause blood disorders

• Eye or vision problems Chloroquine, especially in high doses, may cause serious side effects affecting the eyes

• Glucose-6-phosphate dehydrogenase (G6PD) deficiency Chloroquine may cause serious side effects affecting the blood in patients with this deficiency

• Liver disease May decrease the removal of chloroquine from the blood, increasing the chance of side effects

• Nerve or brain disease (severe), including convulsions (seizures) Chloroquine may cause muscle weakness and, at high doses, seizures

• Porphyria Chloroquine may cause episodes of porphyria to occur more frequently

• Psoriasis Chloroquine may bring on severe attacks of psoriasis

• Stomach or intestinal disease (severe) Chloroquine may cause stomach or intestinal irritation
