That warning is very broad, and without knowing which tablets it refers to, it can be misleading.
Some medications can increase the risk of blood clots or heart problems, but it depends entirely on the drug, dose, and the person using it. For example:
- Hormonal contraceptive pills (estrogen-containing) can slightly increase clot risk in some people.
- Some cancer treatments, steroids, or hormone therapies may also raise risk.
- Certain painkillers (like some NSAIDs, e.g., diclofenac) have been linked to higher cardiovascular risk when used heavily or long-term in high-risk patients.
- Many common medicines have no meaningful clot risk at all when used correctly.
At the same time, for most people taking prescribed medicines appropriately, the absolute risk is usually low—and doctors prescribe them because the benefits outweigh those risks.
What matters most is:
- your age and medical history
- smoking, obesity, inactivity
- previous clot or heart disease
- how long and what dose you’re taking
If you tell me the exact tablet name, I can give a much more accurate explanation of whether that warning applies or is exaggerated.
