Recent global health alerts have prompted pharmacies to withdraw several medications linked to serious cardiovascular risks. Authorities warn that certain hormonal contraceptives, anti-inflammatory drugs, diet pills, and even some COVID-19 treatments may increase the chance of blood clots, strokes, and heart attacks. Regulatory agencies like the FDA and EMA urge patients and doctors to stay informed and review safety updates before starting or continuing these medications.

The main concern centers on abnormal blood clot formation, known as thrombi. While clotting normally protects the body from bleeding, clots that form inside veins or arteries can become dangerous. Depending on where the blockage occurs, vital organs may be deprived of oxygen, leading to life-threatening complications.

Pulmonary embolism, for example, happens when a clot travels to the lungs, causing sudden shortness of breath or chest pain. Deep vein thrombosis involves clots forming in the legs, which can cause swelling and discomfort and may escalate if the clot breaks free. Blood clots in the brain can trigger strokes, while clots in coronary arteries can cause heart attacks—both requiring immediate emergency care.

Health authorities emphasize that awareness and early action are essential. Patients should learn the warning signs, seek urgent medical help if symptoms appear, and always discuss potential medication risks with their healthcare provider.
