Certain medications have been pulled from pharmacies after “serious cardiovascular risks” were discovered. Health authorities warn that some hormonal contraceptives, anti-inflammatories, diet pills, and, in rare cases, COVID-19 treatments “may increase the risk of blood clots, strokes, and heart attacks.” The FDA and EMA urge patients and doctors to review safety updates and discuss concerns before treatment.

The main danger is abnormal blood clot formation, or thrombi. While clotting stops bleeding after injury, clots inside veins or arteries can block blood flow, depriving organs of oxygen and nutrients. This can lead to “pulmonary embolism, deep vein thrombosis, strokes, or heart attacks.”

Pulmonary embolism occurs when a clot travels to the lungs, causing sudden breathlessness, chest pain, and potentially death without urgent treatment. Deep vein thrombosis usually forms in the legs, leading to swelling, pain, and redness, and can progress to more severe complications.

Strokes happen when clots block blood flow to the brain, while heart attacks occur when coronary arteries are obstructed—both requiring immediate medical care.

Authorities stress that “awareness and timely medical intervention are critical.” Patients should know warning signs and consult doctors about possible risks linked to their medications.
