Aspirin is a common medicine used for pain relief, fever reduction, and—at low doses—heart protection. But it also has important risks, especially if used incorrectly or long-term.
⚠️ Serious side effects of aspirin
1. 🩸 Stomach bleeding
- One of the most important risks
- Can cause ulcers or internal bleeding
👉 Warning signs:
- black/tarry stools
- vomiting blood or “coffee-ground” material
- severe stomach pain
2. 🧠 Brain bleeding (rare but serious)
- Higher risk in older adults or high doses
- Can lead to stroke-like symptoms
3. 🫁 Allergic reactions
- Rash, swelling, wheezing, or difficulty breathing
- More common in people with asthma sensitivity
4. 👂 Ringing in ears (tinnitus)
- High doses can cause ringing or hearing changes
5. ⚠️ Reye’s syndrome (in children)
- Rare but life-threatening
- This is why aspirin is not given to children or teenagers with viral infections
❤️ Why doctors still use it
At low doses, aspirin helps:
- prevent blood clots
- reduce risk of heart attack and stroke in selected patients
🚫 Who should be extra careful
- People with stomach ulcers
- Bleeding disorders
- Kidney disease
- Those taking blood thinners
- Older adults (higher bleeding risk)
🧠 Bottom line
Aspirin can be very helpful, but it is not a harmless everyday painkiller. The biggest risk is bleeding, especially in the stomach.
If you want, I can explain safe daily doses, who should take low-dose aspirin for the heart, and who should avoid it completely.
