Summary
Sulfadiazine is used to treat bacterial infections, which are illnesses caused by harmful bacteria. It is effective for conditions like urinary tract infections, which affect the bladder, and certain types of pneumonia, which is an infection of the lungs.
Sulfadiazine works by stopping the growth of bacteria, which are tiny organisms that can cause infections. It does this by interfering with the production of folic acid, which is a vitamin that bacteria need to grow and multiply.
For adults, the usual starting dose of Sulfadiazine is 2 to 4 grams initially, followed by 1 gram every 6 hours. For children, the dose is based on body weight. It is taken by mouth with a full glass of water.
Common side effects of Sulfadiazine include nausea, which is feeling sick to your stomach, vomiting, which is throwing up, and loss of appetite, which means not feeling hungry.
Do not take Sulfadiazine if you are allergic to it or other sulfa drugs, which are a group of antibiotics. It is not recommended for people with severe liver or kidney disease, which are serious conditions affecting these organs.
