[Therapy of paroxysmal hypokalemic paralysis: experience with diclofenamid].

A case of familial hypokalemic periodic paralysis is discussed in a boy whose first paralysis occurred at 11 years of age. At first the paralysis was controlled by acetazolamid and potassium therapy. Later, frequent attacks of paralysis and muscle weakness developed necessitating a change of therapy. Diclofenamid has now already been administered for 2 years. It is well tolerated and has suppressed further attacks.
