If you’re fact-checking “Warning! These tablets can cause blood clots, blood thrombosis, and heart attacks—check the first comment,” the headline is too vague to be medically useful. There are many different medications, and the clot/heart-attack risk varies enormously by drug and by the person taking it.
One important example is combined hormonal contraceptive tablets (containing estrogen and progestin). They can increase the risk of blood clots, and those clots can sometimes lead to pulmonary embolism, stroke, or other cardiovascular complications. The risk is higher in certain groups, such as people who smoke and are over 35 or who have a history of blood clots.

But other tablets actually prevent clots. Anticoagulants such as warfarin are prescribed specifically to reduce harmful clot formation and can reduce the risk of stroke or heart attack in appropriate patients.

So don’t stop a medication based on this headline
A post saying “these tablets” without naming the medication is a major red flag. If you tell me the name of the tablets shown in the post or paste the first comment, I can check the specific drug and explain:
whether it really increases clot/heart-attack risk,
how large the risk is,
who is most vulnerable, and
whether there are legitimate warnings or contraindications.
If you’re currently having chest pain, sudden shortness of breath, coughing blood, or one-sided leg swelling/pain, seek urgent medical care rather than waiting for an online explanation.
