Yaz Side Effects

heart-stroke-imageMultiple studies indicate that taking the birth control pills s Yaz (sold generically as Gianvi and Loryna), Yasmin (sold generically as Ocella, Syeda, and Zarah), Beyaz and Safyral increases a woman’s risk of developing blood clots. Blood clots can cause fatal or debilitating conditions such as strokes, heart attacks and pulmonary embolisms.

The problematic ingredient in Yaz and similar contraceptives is drospirenone. This is a synthetic form of the female hormone progesterone (progestin). Drospirenone-containing birth control pills may also be prescribed to treat premenstrual dysphoric disorder (PMDD) or moderate acne or to raise a woman’s folate (folic acid) levels.

The U.S. Food and Drug Administration (FDA) says that it has “concluded that drospirenone-containing birth control pills may be associated with a higher risk for blood clots than other progestin-containing pills.” In addition, at least one study published in the British medical journal BMJ reports that Yaz may cause as much as a six-fold increase in the risk of developing blood clots.

For more than 30 years, Techmeier Law Firm has stood up for the rights of patients who are injured or killed by defective medical products. If you or a loved one has suffered harm after using Yaz or other drospirenone-containing birth control pills, we are available to fight for you, too.

Risks to Yaz Users from Blood Clots

When blood in your veins or arteries hardens and clumps, it can form a blood clot known as a “thrombus.” When a thrombus breaks free and moves, it is called an “embolus.”

The problem with a thrombus or embolus is that it can partially or completely block the flow of blood. Blockage in an artery may prevent oxygen from reaching nearby tissues, which can lead to tissue damage or death. The restriction of blood-supplied oxygen to tissue is called “ischemia.”

Blood clots can damage the intestines (mesenteric ischemia), kidneys (renal vein thrombosis) or portions of the legs or arms. More importantly, blood clots can cause potentially deadly damage to the vital organs, including:

  • Heart attack – Blockage in a coronary artery can cause a heart attack, which can be fatal if not treated quickly.  Heart attack victims who survive may need medication for the rest of their lives, as well as physical or occupational therapy during their recovery. Once a person has a heart attack, their risk of having another heart attack increases.

Symptoms of a heart attack include chest pain, which may move from the chest to the arms, shoulder, neck, teeth, jaw, belly or back. Pressure in the chest, indigestion and shortness of breath, fatigue, weakness and nausea can also be symptoms.

  • Stroke – A stroke is caused by a blockage that reduces blood flow to the brain. A stroke can be fatal or can cause physical and cognitive (mental) damage, including paralysis, the inability to speak, damage to thought processes and memory, loss of bowel control and more.

Symptoms of stroke usually develop suddenly and without warning and may come and go for a day or two. They include a sudden and severe headache; changes in alertness, hearing, taste and the ability to feel pain; pressure or different temperatures; confusion, loss of motor skills, balance and coordination; muscle weakness in the face, arm or leg (usually just on one side); numbness or tingling sensation (usually on one side of the body); loss of speech; changes in vision; and personality, mood or emotional changes.

  • Pulmonary embolism (PE) – A pulmonary embolism is a blockage in a lung. Deep vein thrombosis (DVT), a blood clot originating deep inside the body (usually the large veins in the lower leg or thigh) is often the cause of a pulmonary embolism. A PE can cause a heart attack or be fatal on its own. If treated quickly, anticoagulation therapy (blood thinning medication) can dissolve the blood clot.

Symptoms of DVT include pain in the legs, redness, swelling (edema) and skin that feels warm to the touch. Symptoms of PE include sharp or stabbing chest pain under the breastbone or on one side, sudden cough (possibly coughing up blood or bloody mucus), rapid breathing, rapid heart rate and shortness of breath.

If you have symptoms of any of these maladies, you should seek medical help immediately.

Bayer HealthCare Pharmaceuticals, the maker of Yaz, also says that Yaz may cause headache, migraines, menstrual irregularities, nausea, vomiting, breast pain or tenderness, fatigue, irritability, decreased libido, weight gain and mood changes.

As with any medication, you should consult your doctor before stopping or starting to take Yaz, Yasmin, Ocella, or any other birth control pill. If you have experienced a serious adverse side effect that may have been caused by a drospirenone-containing contraceptive, you should contact a defective medical products attorney experienced with Yaz and similar birth control products.
