If you’re referring to a warning about tablets that can increase the risk of blood clots, heart attack, or stroke, the specific medicine matters enormously. One important example is tofacitinib (Xeljanz) and other JAK inhibitors, for which regulators have issued warnings about serious cardiovascular events and blood clots in certain patients. Pakistan’s Drug Regulatory Authority has also issued a safety alert.
Another category is NSAID painkillers. Certain NSAIDs, including ketorolac, can increase the risk of heart attack and stroke, particularly with longer use or in people who already have cardiovascular disease.
⚠️ Don’t stop a prescribed medicine because of a headline
The risk depends on the exact drug, dose, duration of use, age, smoking history, and cardiovascular risk factors. Stopping some medicines abruptly can also be dangerous.
If you tell me the name of the tablet (or send a photo of the package), I can check the official safety information and explain:
- what the actual clot/heart-attack risk is,
- who is most at risk,
- warning symptoms to watch for, and
- whether the medicine should be discussed with your doctor.
