Free SP first appears in plasma in 4.3 hours after a single dose with an absorption half life of 2.7 hours. Assessment of renal function (including urinalysis) should be performed in all patients initially and at least monthly for the first three months of treatment. Sulfasalazine will not cure ulcerative colitis, but it can reduce the number of attacks you have. The following advice is for the management of patients taking DMARDs for rheumatology related conditions. You also shouldn’t take sulfasalazine if you are allergic to antibiotics known as sulphonamides.Disease-modifying anti-rheumatic drugs (DMARDs) alter the underlying disease rather than treating symptoms.
In the gut sulfasalazine is broken down (by the normal gut bacteria) into two parts: one part a sulphonamide antibiotic which kills harmful bacteria; and a second part which acts to reduce the process driving inflammation as well as helping to control the overactive immune system.
They should be swallowed whole with a glass of water, not crushed or chewed.Your doctor will advise you on the correct dose to take. Sulfasalazine and sulfapyridine are found in low levels in breast milk. This overactive immune system in RA is the cause of swelling, pain, heat and redness in the joints and other associated symptoms such as fatigue and generally feeling unwell.

After a 3g SASP dose lag time was 6.1 ±2.3 hours and plasma levels kept below 2µg/ml total ME. Some undesirable effects are dose-dependent and symptoms can often be alleviated by reduction of the dose.Sulfasalazine is split by intestinal bacteria to sulfapyridine and 5-amino salicylate so ADRs to either sulfonamide or salicylate are possible. Here levels of SP over about 50µg/ml are associated with a substantial risk of ADRs, especially in slow acetylators. Where an adverse reaction was seen at different frequencies in clinical studies, it was assigned to the highest frequency reported. It did not induce sister chromatid exchanges or chromosomal aberrations in cultured Chinese hamster ovary cells, and in vivo mouse bone marrow chromosomal aberration tests were negative. The lowered sperm count is reversed when you stop . Rapid passage of the tablets may reduce effect of the drug.Night-time interval between doses should not exceed 8 hours.2-4 tablets four times a day may be given in conjunction with steroids.With induction of remission reduce the dose gradually to 4 tablets per day.

It is taken by mouth. by remembering to have regular blood test monitoring as advised by the consultant or clinical nurse specialist Remember that contraception is still required if men taking  do not wish to father a child even though the sperm count is likely to be lowered Oral sulfasalazine inhibits the absorption and metabolism of folic acid and may cause folic acid deficiency. If sulfasalazine is used during pregnancy, the possibility of foetal harm appears remote.
