I've recently had to stop taking aspirin because of acid reflux. Have tried clopidogrel and coated aspirin since but reflux persists. Stomach is much improved since stopping said meds. The reason I was taking aspirin was because of a mild heart attack 12 years ago. No issues since, but am a bit concerned that something might crop up in the future. Are there any other suitable blood thinning meds I can try? I was injected with fragmin during a couple of stays in hospital, but have my doubts if that would fit the bill?
