If you’re referring to the viral warning “These tablets can cause blood clots, thrombosis, and heart attacks,” the claim needs context. Some medicines really can increase the risk of blood clots or cardiovascular events, but it does not mean everyone taking them will develop a clot or heart attack.
Medicines that can carry these risks
- Combined hormonal contraceptive pills containing estrogen and a progestin can increase the risk of blood clots, stroke, and, rarely, heart attack. Risk is higher with factors such as smoking, older age, high blood pressure, obesity, or a history of clotting problems. MedlinePlus+1
- Some NSAID painkillers, such as naproxen and other NSAIDs, can increase the risk of serious cardiovascular events, including heart attack and stroke, particularly with higher doses or longer use. DailyMed
- Menopausal hormone therapy can increase the risk of blood clots, stroke, and heart attack in some women, so the decision to use it should be individualized with a healthcare professional. U.S. Food and Drug Administration
🚨 Don’t stop a medication suddenly
A medicine’s risk depends on the exact drug, dose, duration, age, medical history, and other medicines you’re taking. Some medications that carry cardiovascular risks are still very appropriate when prescribed for the right person.
If you’re taking a particular tablet and are worried, tell me its exact name (or send a photo of the package) and I can explain its actual blood-clot and heart-attack risk.
If someone taking any medication develops sudden chest pain, difficulty breathing, coughing blood, one-sided leg swelling/pain, sudden weakness, or trouble speaking, seek emergency medical care.
