Can you take azithromycin with colchicine?

Which drug can cause colchicine levels to go too high?
HIV drugs, such as indinavir, atazanavir, nelfinavir, saquinavir, or ritonavir. Using these drugs with colchicine can result in very high levels of colchicine in your body. This raises your risk of side effects, such as severe muscle damage. Antibiotics, such as clarithromycin or telithromycin.
