kidney or liver disease;

a folic acid deficiency;

asthma or severe allergies;

AIDS;

a glucose-6-phosphate dehydrogenase deficiency (G6PD deficiency); or

if you are malnourished.

Relate drugs

How to use Cotrim

Take Cotrim exactly as prescribed by your doctor. Do not take it in larger amounts or for longer than recommended. Follow the directions on your prescription label.

Take Cotrim for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Cotrim will not treat a viral infection such as the common cold or flu. Drink plenty of fluids to prevent kidney stones while you are taking trimethoprim and sulfamethoxazole. Store the tablets and liquid at room temperature away from moisture, heat, and light.

Warnings

Before using Cotrim, tell your doctor if you have kidney or liver disease, a folic acid deficiency, asthma or severe allergies, AIDS, a glucose-6-phosphate dehydrogenase deficiency (G6PD deficiency), or if you are malnourished.

Take Cotrim for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Cotrim will not treat a viral infection such as the common cold or flu.

Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or has blood in it, call your doctor. Do not use any medicine to stop the diarrhea unless your doctor has told you to.

Avoid exposure to sunlight, sunlamps, or tanning beds. Cotrim can make your skin more sensitive to sunlight, and a sunburn may result. Wear protective clothing and use sunscreen (SPF 15 or higher) when you are outdoors.

What other drugs will affect Cotrim

You may need more frequent check- ups or medical tests if you also use medicine to treat depression, diabetes, seizures, or HIV.

Tell your doctor about all your current medicines. Many drugs can affect sulfamethoxazole and trimethoprim, especially:

amantadine, cyclosporine, indomethacin, leucovorin, methotrexate, pyrimethamine;

an "ACE inhibitor" heart or blood presure medication (benazepril, enalapril, lisinopril, quinapril, ramipril, and others); or

a diuretic or "water pill" (chlorthalidone, hydrochlorothiazide, and others).

This list is not complete and there may be other drugs that can interact with Cotrim. Tell your doctor about all your prescription and over-the-counter medications, vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start a new medication without telling your doctor.
