Thrombi are abnormal blood clots that form inside veins or arteries. While clotting is essential to stop bleeding, when it occurs within the bloodstream without injury, it can obstruct blood flow to vital organs—leading to:
Pulmonary embolism (clot in the lungs)
Stroke (clot in the brain)
❤️ Heart attack (clot in the coronary arteries)
Deep vein thrombosis (DVT)
Even one untreated clot can be fatal. That’s why any drug linked to increased clotting risks is taken seriously by global health regulators.
Medications Under Review or Withdrawal
While exact names and formulations vary by region, the most cited categories include:
Hormonal contraceptives (especially certain 3rd-generation types)
Some anti-inflammatory medications
Select diet pills and appetite suppressants
Rare cases involving COVID-19-related treatments and vaccines
Authorities such as the U.S. Food and Drug Administration, the European Medicines Agency, and national health ministries have placed usage restrictions, issued recalls, or suspended approvals.
Risk appears highest among individuals with pre-existing health issues like:
Hypertension
Obesity
Diabetes
Smoking history
Genetic clotting disorders
