Texas Yaz LawsuitDeep Vein Thrombosis (DVT) is a serious, life-threatening side effect of Yaz. Recently, the U.S. Food and Drug Administration (FDA) announced that it would require Yaz manufacturers to update the Yaz label to warn about the increased risk of blood clots. These blood clots often form deep inside the body, in a condition called Deep Vein Thrombosis (DVT). In the most serious cases, Yaz DVT blood clots can break loose and cause a deadly pulmonary embolism.

April 2012: This month, the FDA announced that the labels of all birth control pills containing drospirenone will be updated to warn of an increased risk of blood clots compared to other birth control pills. The labels of Yaz birth control pills will be updated to reflect these new warnings.


Yaz is a hormonal birth control pill that is sold by Bayer HealthCare Pharmaceuticals, Inc. The U.S. Food and Drug Administration (FDA) approved Yaz in 2006 to prevent unwanted pregnancy. Each “active” Yaz pill contains a combination of two hormones:

  • 0.02-mg ethinyl estradiol, synthetic estrogen
  • 3-mg drospirenone, synthetic progestin

Do you use Yaz birth control pills? If so, you may have recently heard that this medication has been linked to a higher risk of blood clots compared to other birth control pills. This is because Yaz contains a new type of ingredient called drospirenone, which is a “fourth generation” version of synthetic estrogen. An FDA-funded research study of drospirenone-containing birth control pills found that women who were using these contraceptives were three times more likely to develop a life-threatening blood clot.

Yaz and Deep Vein Thrombosis (DVT)

Multiple studies have linked Yaz birth control pills to a higher risk of blood clots compared to non-drospirenone birth control pills. These blood clots usually form in veins that are located deep within the body, in a condition known as Deep Vein Thrombosis (DVT).

When a person has DVT, blood clots form inside veins located deep within the body. These veins are usually located in the lower leg. Sometimes, DVT blood clots also form in the thighs, pelvis, or upper arms. On its own, DVT doesn’t normally cause side effects more serious than pain and swelling in the affected area. However, if a blood clot breaks loose (called an embolism), it travels through the blood stream until it is too large to fit through a smaller blood vessel. This often occurs in the lungs, causing a potentially deadly condition called a pulmonary embolism. When a blood clot gets trapped in the lungs, it stops the flow of blood into lung tissue. This can cause lung tissue to die. It can also prevent blood from receiving fresh oxygen in the lungs. If untreated, around 30% of cases of pulmonary embolisms cause death.

Symptoms of Yaz DVT Blood Clots

If you use Yaz birth control pills, it is possible that you have a higher risk of developing a life-threatening blood clot. This is why it is important to recognize the symptoms of DVT. However, not all cases of DVT show symptoms. In fact, around half of DVT cases are symptomless. Once a blood clot causes a heart attack, stroke, or pulmonary embolism, it may be too late.

Early symptoms of a Yaz DVT blood clot include:

      • Discoloration of the affected part of the body (such as one leg)
      • Pain in the affected extremity
      • Swelling in the limb
      • Warmth in the area of the blood clot
      • Superficial veins may look engorged
      • Weakness, tingling, or abnormal sensation in the affected limb

Treatment for a Yaz DVT Blood Clot

Any time a blood clot is suspected, this is a life-threatening emergency situation. Once a patient reaches the emergency room, the first step will usually be administering a blood-thinning medication. This medication can prevent a blood clot from getting any larger. This reduces the risk that the blood clot will break loose, become an embolism, and cause a pulmonary embolism.

If the medications do not work, or if the blood clot is very large, a doctor may be forced to administer an intravenous medication directly into the area where the blood clot is located. Specialized “clot-busting” drugs are very effective at eliminating blood clots from the body. However, because they have a high risk of serious bleeding, they should only be used in life-threatening situations.
