of the heart is blocked.
Deep vein thrombosis (DVT), when a clot forms in a deep vein, commonly in the leg.
Some blood clots can become life-threatening if they are not recognized and treated promptly. For this reason, medications with documented or suspected effects on clotting or cardiovascular health may be subject to safety reviews and regulatory action.

Medications Under Review or Associated With Cardiovascular Risks
The specific medications, formulations, and regulatory actions can vary by country and over time. Categories discussed in connection with cardiovascular or clotting risks have included:
Hormonal contraceptives, including certain formulations that may carry different levels of blood-clot risk.
Certain anti-inflammatory medications, for which cardiovascular risks may depend on the specific drug, dose, and duration of use.
Some weight-loss medications
