A warning like “These tablets can cause blood clots and heart attacks” is too vague to be reliable. Whether a medication increases those risks depends on which medication it is, the dose, and the person’s medical history.
Some medicines are known to increase the risk of blood clots or cardiovascular events in certain people. Examples include:
- Estrogen-containing birth control pills and some hormone replacement therapies: These can increase the risk of blood clots, particularly in people who smoke, are over 35, have obesity, or have certain clotting disorders.
- Some pain relievers (NSAIDs), such as ibuprofen or diclofenac: Long-term or high-dose use may slightly increase the risk of heart attack or stroke in some people, especially those with existing cardiovascular disease.
- Certain cancer treatments and some medications for autoimmune diseases: Depending on the drug, they may increase the risk of blood clots.
However, most tablets do not cause blood clots, and even medications that carry this risk are often appropriate because their benefits outweigh the risks for many people.
If you are taking a medication and experience symptoms that could suggest a blood clot or heart attack—such as:
- sudden chest pain,
- shortness of breath,
- swelling, pain, warmth, or redness in one leg,
- sudden weakness on one side,
- difficulty speaking,
seek emergency medical care immediately.
If you can tell me the name of the tablets or share a photo of the package or post, I can explain what the actual risks are and whether the warning is accurate.
