Sulfapyridine (sul-fa-PEER-i-deen) is a sulfa medicine. It is used to help control dermatitis herpetiformis (Duhring's disease), a skin problem. It may also be used for other problems as determined by your doctor. However, this medicine will not work for any kind of infection as other sulfa medicines do.
This medicine may cause some serious side effects. Before using this medicine, be sure to talk to your doctor about these problems, as well as the good this medicine will do .
Sulfapyridine is available only with your doctor's prescription, in the following dosage form:
Before Using This Medicine
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 sulfapyridine, the following should be considered:
Allergies- Tell your doctor if you have ever had any unusual or allergic reaction to sulfa medicines, furosemide (e.g., Lasix) or thiazide diuretics (water pills), oral antidiabetics (diabetes medicine you take by mouth), glaucoma medicine you take by mouth (acetazolamide [e.g., Diamox], dichlorphenamide [e.g., Daranide], methazolamide [e.g., Neptazane]), or pyrimethamine (e.g., Daraprim). Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.
Pregnancy- Studies have not been done in humans. Studies in rats and mice have shown that some sulfa medicines, given by mouth in high doses, cause birth defects, including cleft palate and bone problems. In addition, sulfa medicines may cause liver problems in newborn infants. Therefore, use is not recommended during pregnancy.
Breast-feeding- Sulfapyridine passes into the breast milk. This medicine may cause liver problems in nursing babies. In addition, it may cause blood problems in nursing babies with glucose-6-phosphate dehydrogenase (G6PD) deficiency (lack of G6PD enzyme). Therefore, use is not recommended in nursing women.
Children- Use of this medicine is not recommended since dermatitis herpetiformis usually does not occur in children.
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 the use of sulfapyridine 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 sulfapyridine, it is especially important that your health care professional know if you are taking any of the following:
Other medical problems- The presence of other medical problems may affect the use of sulfapyridine. Make sure you tell your doctor if you have any other medical problems, especially:
Proper Use of This Medicine
Each dose of sulfapyridine should be taken with a full glass (8 ounces) of water. Several additional glasses of water should be taken every day , unless otherwise directed by your doctor. Drinking extra water will help to prevent some unwanted effects (e.g., kidney stones) of the sulfa medicine.
For patients taking sulfapyridine for dermatitis herpetiformis :
The dose of sulfapyridine will be different for different patients. Follow your doctor's orders or the directions on the label . The following information includes only the average doses of sulfapyridine. Your dose may be different if you have kidney disease. If your dose is different, do not change it unless your doctor tells you to do so.
For patients taking sulfapyridine for dermatitis herpetiformis : You may skip a missed dose if this does not make your symptoms return or get worse. If your symptoms do return or get worse, take the missed dose as soon as possible. Then go back to your regular dosing schedule.
