Guest guest Posted March 23, 2005 Report Share Posted March 23, 2005 Chloroquine (CQ) and hydroxychloroquine (HCQ) are a members of the quinolone family, at the molecular level, these are different than fluroquinolines (with which they are sometimes confused). There is a molecular distinction between fluroquinoline and quinolones (please notice the spellings.. the " i " instead of the " o " and the fluro prefix) which includes their side effects and there are also distinctions between CQ and HCQ. As far as I know, the tendon degradation problems with the fluroquinolines are not listed as side effects by the drug companies witht these anti malarial quinolones. But these (antimalarial) drugs do have side efects , especially with raising the intraocular pressure (and you can't feel that happening). Chloroquine (CQ) is more dangerous than hydroxychloroquine (HCQ) and they have very long half lives, and unbeleivably long wash-out periods see this site: http://www.fqresearch.org/vision_archives.htm In some infections HCQ is used in combo with other drugs long term and there's quite a bit of data out there about HCQ and Doxy: http://archinte.ama-assn.org/cgi/content/abstract/159/2/167 My docs baselined my IOC (introcular pressure) when starting HCQ, even though it used as a monotherapy and used at the safe dose (<400mg/day) and I was monitored thru higher doses. My eyes were really bad, and I was seeing my ohpthalmologist every week anyway.. measuring a bunch of eye problems - so I was monitored extremely closely. So although I used > 400mg and in combo with other abx, for some unknown reason, my intra-ocular pressure never increased.. So I was lucky. And IMO this isn't a drug anyone should self medicate (not that any one would do that - but I need to say that because we are talking about ones eyes after all). And in my case, there did appear to be a synergy, or additive effect when HCQ was combined some other abx. (see my other posts on HCQ). With HCQ and Mino the dosages of both drugs were reduced by about two thirds or I would reach too high a consentration in the inner ear, and vestibular dyfunction resulted (disabling vertigo from the Mino consentration in the inner ear). So people - HCQ is a drug that IMO if you use it with other drugs, you need to be under the care of not just any Dr.. but a smart Dr. ... you know.. some of these drug combo's are really a double edged swords, and one really has to weight the risks. I really really really worry about the the side efects of toxicity being misinterpreted as herx when HCQ is used in combo with other abx because tissue consentration levels will vary greatly between people depending the combo drug used and the person's own genetic metabolic make up. .. and I've seen plenty of reports of people calling these effects herxes....and I just chringe.
