Doxycycline Drug Interactions
When certain medications are taken with doxycycline, drug interactions may occur that can result in serious side effects. Examples of drug interactions that may cause the body to metabolize the medicines differently than intended include warfarin, oral contraceptives, and retinoids. Other doxycycline drug interactions can cause reduced effectiveness of one (or both) medicines and increased levels of these drugs in your system.
