A Canadian study warns clinicians and patients to be careful about mixing blood thinners with antibiotics because the combination could increase the risk of gastrointestinal bleeding. In particular, caution should be given when combining the blood thinner warfarin and the antibiotic cotrimoxazole, which is a combination of sulfamethoxazole and trimethoprim. "Both are very common medications, and the risk that they would be combined is very real," a researcher said.
