The influence of renal impairment on the pharmacokinetics of haloperidol has not been evaluated. About one-third of a haloperidol dose is excreted in urine, mostly as metabolites. Less than 3% of administered haloperidol is eliminated unchanged in the urine. Haloperidol metabolites are not considered to make a significant contribution to its activity, although for the reduced metabolite of haloperidol, back-conversion to haloperidol cannot be fully ruled out. Even though impairment of renal function is not expected to affect haloperidol elimination to a clinically relevant extent, caution is advised in patients with renal impairment, and especially those with severe impairment, due to the long half-life of haloperidol and its reduced metabolite, and the possibility of accumulation (see section ).
A 2005 paper suggested leuprorelin as a possible treatment for autism ,  the hypothetical method of action being the now defunct hypothesis that autism is caused by mercury , with the additional unfounded assumption that mercury binds irreversibly to testosterone and therefore leuprorelin can help cure autism by lowering the testosterone levels and thereby mercury levels.  However, there is no scientifically valid or reliable research to show its effectiveness in treating autism.  This use has been termed the "Lupron protocol"  and Mark Geier , the proponent of the hypothesis, has frequently been barred from testifying in vaccine-autism related cases on the grounds of not being sufficiently expert in that particular issue    and has had his medical license revoked.  Medical experts have referred to Geier's claims as "junk science".
