Immunodeficient individuals are at higher risk for infection with Pneumocystis carinii and are frequently put on a regular preventive drug regimen of trimethoprim sulfa and/or inhaled pentamidine to avoid pneumocystis pneumonia.
Causes of fasting hypoglycemia in children without diabetes may include insulin-producing tumors, certain hormonal deficiencies, medications (including sulfa drugs and large doses of aspirin), and critical illnesses.
Aftershave lotions, sunscreens, and certain topical sulfa drugs may be changed into allergens, while coal tar and certain oils used in manufacturing may become irritants after light exposure.
Recommended antibiotics include ampicillin, sulfa derivatives such as trimethoprim-sulfamethoxazole (TMP-SMX) sold as Bactrim, or fluoroquinolones, such as Ciprofloxacin.
Penicillin and sulfa drugs are not suitable for treatment of RMSF, and their use may increase the death rate by delaying the use of truly effective medications.
