How does erythromycin interact with other medications and what precautions are needed to avoid adverse drug interactions or reduced efficacy?
1. Erythromycin increases blood levels of certain drugs, such as warfarin and theophylline, heightening their effects and risks.
2. It can also slow the breakdown of drugs like cyclosporine and digoxin, potentially leading to toxicity.
3. Concurrent use with statins can raise the risk of muscle damage, so closely monitor these levels.
4. Erythromycin may reduce the efficacy of hormonal contraceptives, so additional contraceptive measures are advised.
5. It can interfere with the metabolism of drugs like carbamazepine, leading to increased side effects.
