Can you tell me if lodine (etodolac) xl contains aspirin?

No, it does not: Hi. Lodine is an NSAID called etodolac. Aspirin is also an NSAID, but there is no aspirin in any of the Lodine preparations. Note that aspirin and etodolac can have some similar side effects, particularly GI irritation. If you have an aspirin allergy, be sure you mentioned this to your doctor before he/she prescribed etodolac. To your health!
