[Undesirable effects of gold therapy]

In about 20 to 30% of patients receiving intramuscular gold salts untoward side-effects of variable severity are known to occur with resultant discontinuation of treatment in a high percentage of cases to be on the safe side. Among the most common, albeit harmless side-effects are those affecting the skin and the mucous membranes. These are followed by renal symptoms. Grave complications affecting the hemopoietic system (leucopenia, thrombocytopenia, aplastic anaemia) are rarely seen. Other potential side effects (pulmonary fibrosis, liver damage, neuropathies, vasomotor reactions, loss of hair, nail changes) are extremely uncommon or no more than anecdotal). Meticulous follow-ups at regular intervals are imperative to minimize the associated risks.
