RT Journal Article SR Electronic T1 Complications of `Slow-K' therapy JF The Journal of the Royal College of General Practitioners JO J R Coll Gen Pract FD British Journal of General Practice SP 595 OP 598 VO 26 IS 169 A1 Sandor, Francis YR 1976 UL http://bjgp.org/content/26/169/595.abstract AB (1) The failure of `Slow-K' tablets to disintegrate prevents rapid release but allows them to be trapped by their bulk in the intestine. (2) Two cases are reported. In the first the tablet was trapped in a caecal diverticulum and the patient developed an abcess. In the second, abdominal pain developed which subsided when `Slow-K' was stopped. Later `Slow-K' was again started and the patient developed dysphagia. (3) The possibility of abdominal complications with this treatment should be remembered. (4) Effervescent KC1 preparations may replace `Slow-K' but KC1 supplementation may be necessary only in cardiac disease.
