Public-health officials are scaling back official recommendations for the painkiller to target a narrower group of patients who are at risk of a heart attack or stroke.
They’re worried about side effects, such as ulcers. As the UK Netdoctor says,
The second most common cause [of peptic ulcers] is damage inflicted by aspirin (eg Disprin) or non-steroidal anti-inflammatory drugs (NSAIDs, such as diclofenac (eg Voltarol) or naproxen (eg Synflex)) used by many for arthritis, rheumatism, backache, headaches and period pain.
It’s always something.
