Cipro or Ciprofloxacin is not a sulfa drug and instead is a quinolone antibiotic and is unlikely to trigger an allergic reaction if you have a sulfa allergy.
Examples of sulfonamide drugs are Sulfamethoxazole, Sulfadiazine, Sulfamethizole, Sulfasalazine, Chlorthalidone, Sulfisoxazole, Tolbutamide, Zonisamide Oral, Indapamide, Mafenide, Metolazone, Probenecid, Sulfacetamide, Sumatriptan, Azulfidine, Bumetanide, Furosemide, Gantrisin, Hydrochlorothiazide and Sulfaguanidine
Sulfonamide drugs are a functional group that is the basis of several groups of drugs, that are called sulphonamides, sulfa drugs or sulpha drugs.
The original antibacterial sulfonamides are synthetic antimicrobial agents that contain the sulfonamide group.
Sulfa drugs, also called sulfonamides, include antibiotics as well as other types of drugs.
Allergies happen most often with antibiotics.
Commonly prescribed sulfonamide drugs include include sulfasalazine (Azulfidine, Azulfidine EN-tabs), acetazolamide xr (Diamox Sequels), acetyl sulfisoxazole pediatric suspension (Gantrisin), sulfisoxazole (Trixazole), and Zonegran (zonisamide (Zonegran).
Sulphonamides are an important class of antibiotic drugs with a wide range of activity, being very effective against gram-positive and certain gram-negative bacteria.
Sulfonamides may cause your skin to be more sensitive to sunlight than it is normally.
Exposure to sunlight, even for brief periods of time, may cause a skin rash, itching, redness or other discoloration of the skin, or a severe sunburn.
Drugs that should be avoided with a sulfa allergy include.
Sulfamethoxazole-trimethoprim (Septra, Bactrim)
Erythromycin-sulfisoxazole.
Today, sulfonamides are seldom used as monotherapy because their spectrum is limited and resistance develops rapidly.
Combined with a folate antagonist such as trimethoprim or pyrimethamine, sulfonamides are indicated among others in the treatment of toxoplasmosis and malaria.
