colchicine and kaletar
May 23, 2012
One of my Dr.'s prescribed colchicine .6 mg once a day and i also take Kaletra... i ran them through the drug checker and see that they do not get along very well...i also read that maybe i should be taking .3 (.6 cut in half) of the colchicine every other day to avoid toxicity and to maintain the prescribed dosage of .6 Is this correct or should i just take it as prescribed?
Thanks very much...

Hi and thanks for posting.
This is from a post earlier this month:
Colchicine, a medication used to treat acute gout attacks and to prevent recurrences does have the potential to interact with HIV medications- in particular, HIV protease inhibitors, like your ritonavir (Norvir) and atazanavir (Reyataz). The interaction has the potential to significantly increase the levels of colchicine in your blood, and therefore the risk of toxicity.
It's recommended that if you require colchicine, that the dose you take be reduced from normal by 75%. That would mean going from 0.6 mg daily to 0.15 mg daily (a quarter tablet). This dose would require cutting your tablet into smaller fragments, something that a pill cutter would be very helpful in doing.
Of course, anytime you have a potential drug interaction doesn't mean that you can't take the combination, but rather that you need to be mindful of the possibility of problems and monitor things accordingly.
I hope that helps, BY
