Aamir [/INST] Hi Amir Khan, Thank you for posting your query. Marevan (warfarin) is an anticoagulant and Joplin (aspirin) is an antiplatelet. Both these Chat Doctor. Generally, these medications are required life-long, however, your doctor would help you more in this regard. The commonest side effects are bleeding-such as from nose, in urine, while passing stools, from gums while brushing teeth. If any of these occur, please discuss with your doctor. Please get back if you require any additional information. Best wishes,  </s>
