2. Veterinary Medications: Sulfa drugs are commonly used in veterinary medicine to treat infections in animals. They may be administered orally, intravenously, or applied topically.

3. Food Preservatives: Certain sulfa drugs, such as sodium metabisulfite and sodium sulfite, are used as preservatives in processed foods and beverages to prevent spoilage and extend their shelf life.

4. Hair Dye: Some hair dye products contain sulfa drugs to combat bacterial infections that can occur during the dyeing process.

5. Diaper Rash Ointments: Sulfa-based diaper rash ointments may be used to prevent and treat diaper rash in infants.
