Aspirin is a common over-the-counter medication used to alleviate pain, reduce inflammation, and prevent heart attacks and strokes. However, like any medication, it can cause side effects. Common side effects of aspirin include stomach pain, heartburn, and stomach ulcers. To alleviate these side effects, consider the following steps:

1. Take aspirin with food or milk: Taking aspirin with food or milk can help reduce stomach irritation and the risk of stomach ulcers [1].
2. Use enteric-coated aspirin: Enteric-coated aspirin is designed to dissolve in the intestines rather than the stomach, reducing the risk of stomach irritation [1].
3. Limit alcohol consumption: Drinking alcohol while taking aspirin can increase the risk of stomach ulcers and bleeding [1].
4. Consider a different medication: If you experience severe or persistent side effects from aspirin, talk to your doctor about alternative medications [1].

It's important to note that aspirin can interact with other medications and health conditions. Always consult with your doctor or pharmacist before starting or stopping any medication [2].

In addition, it's important to be aware of the potential for aspirin allergies and overdoses. Seek medical attention immediately if you experience symptoms of an allergic reaction or overdose, such as hives, difficulty breathing, or seizures [2].

In summary, to alleviate aspirin side effects, consider taking aspirin with food or milk, using enteric-coated aspirin, limiting alcohol consumption, and talking to your doctor about alternative medications. Always consult with your doctor or pharmacist before starting or stopping any medication.
