Before Using This Medicine

In deciding to use a medicine, the risks of using the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For idoxuridine, the following should be considered:

Allergies - Tell your doctor if you have ever had any unusual or allergic reaction to idoxuridine or to iodine or iodine-containing preparations. Also tell your health care professional if you are allergic to any other substances, such as preservatives.

Pregnancy - Idoxuridine ophthalmic preparations have not been shown to cause birth defects or other problems in humans. However, studies in animals have shown that idoxuridine causes protruding eyes (eyes that stick out too far) and deformed front legs in rabbits. Before using this medicine, make sure your doctor knows if you are pregnant or if you may become pregnant.

Breast-feeding - It is not known whether idoxuridine passes into the breast milk. Although most medicines pass into breast milk in small amounts, many of them may be used safely while breast-feeding. Mothers who are using this medicine and who wish to breast-feed should discuss this with their doctor.

Children - Studies on this medicine have been done only in adult patients, and there is no specific information comparing use of this medicine in children with use in other age groups.

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 idoxuridine 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 using idoxuridine, it is especially important that your health care professional know if you are using the following:

• Eye product containing boric acid - Boric acid may interact with the idoxuridine preparation causing a gritty substance to form or may interact with the preservative in the idoxuridine preparation causing a toxic effect in the eye
