Other side effects include nausea, vomiting, dizziness, tiredness and headache. There are however also severe side effects including severe allergic reactions, like (nettle) rash, itch, tightness in chest, difficult breathing and swelling in either the face, mouth, lips or tongue. Other severe side effects include bloody or severe diarrhea, fever, joint pain, red, blistered or swollen skin and stomach pain. In the eye, it can cause conjunctivitis. There are also life-threatening conditions which can be produced by the antibiotic, like Stevens Johnson syndrome and Erythema multiforme. Higher exposure can also cause unconsciousness. One case showed that sulfacetamide eyedrops can very rarely cause life-threatening skin condition toxic epidermal necrolysis (TEN). These are however not all side effects. For more information the health care provider can be contacted. Sulfacetamide should not be used by individuals who have a sensitivity to sulfur or sulfa. Toxicity
The acute oral toxicity (LD50) in a mouse is 16.5 g/kg. As this falls within Toxicity Category IV of the toxicity category rating for oral administration, it is practically non-toxic and also not an irritant when taken in orally. However, it is very hazardous in case of skin contact (irritant), ingestion and inhalation. Research proved that it is more toxic in the presence of light than in the dark. Sulfacetamide is slightly irritant when UV-A light is present. In the presence of light sulfacetamide gets sensitized and degraded which might cause irritation which will lead to toxicity when it is used continuously. In the dark only slight irritation has been shown.
Serpiginous choroiditis, also known as geographic or helicoid choroidopathy, is an uncommon chronic progressive inflammatory disease affecting adult men and women equally in the second to seventh decades of life. Presentation
In this condition the posterior uveitis shows a geographic pattern. The inflammation begins in the juxtapapillary choroid and intermittently spreads centrifugally. The overlying retinal pigment epithelium and the outer retina are involved in the inflammatory process. A closely related condition is multifocal serpiginoid choroiditis. This is caused by tuberculosis.The distinction between these two conditions is important as the latter responds to anti tuberculosis treatment while the former does not. Diagnosis
