Can you take doxycycline and lovenox and coumadin together?

Doxycycline and lovenox have no drug interactions between themselves, however they both interact with Caumadin.

Doxycycline and lovenox may enhance the anticoagulant effect of coumadin resulting in the delayed clotting of blood or spontaneous bleeding. The benefits of combined use of these two medications usually outweigh the risks and you should talk to your doctor if you have any concerns as dosage and timing do play a role in unwanted side effects.
