Teva Pharmaceuticals’ popular birth control pill Gianvi has been increasingly linked to the development of blood clots, which have the potential to cause deep vein thrombosis (DVT) events. Experts believe Gianvi’s prothombotic effects may be due to the drospirenone contained in the drug, which is a diuretic that can increase potassium levels and cause life-threatening blood clots. Signs and symptoms of a Gianvi-induced deep vein thrombosis may include swelling in one or both legs, warmth in the skin, visible surface veins, and leg fatigue.
What is Deep Vein Thrombosis (DVT)?
Among the most serious side effects to be reported by Gianvi users are thrombosis events, which occur when a blood clot (thrombus) forms in a blood vessel. If the thrombus dislodges itself and migrates through the bloodstream, it becomes a thromboembolism. Depending on where the clot ends up, a variety of adverse complications may ensue. A thromboembolism that plugs a vessel in the lungs leads to a pulmonary embolism, while one that finds its way to the brain may result in a stroke. Clots also commonly block the gastrointestinal tract, kidneys, and legs.
Gianvi Deep Vein Thrombosis Symptoms
The following signs and symptoms may indicate that you are suffering from a Gianvi-induced deep vein thrombosis:
- Swelling in one or both legs
- Pain or tenderness in one or both legs which may occur only while walking or standing
- Warmth in the skin
- Red or discolored skin
- Visible surface veins
- Leg fatigue
If you are a Gianvi user and are experiencing any of the symptoms, you should contact your physician immediately. Depending on the specifics of your particular case, the doctor may recommend an MRI, ultrasound, blood test or venography to make a conclusive diagnosis.
If you have suffered from a deep vein thrombosis after taking Gianvi, treatment methods typically aim at stopping the blood clot from getting any bigger, preventing the clot from migrating and becoming a pulmonary embolism, and preventing another DVT from occurring. Possible courses of treatment may include:
- Blood thinners
- Clot busters
- Compression stockings
All birth control pills present some risk for blood clotting disorders such as deep vein thrombosis. However, this risk is significantly increased in users of Gianvi and other drospirenone-containing contraceptives. This is because drospirenone acts as a diuretic which thickens the blood, leading to severe heart rhythm disturbances and deep vein thrombosis.
