Side Effects of Yaz
Yaz and Yasmin birth control pills have been linked to a range of debilitating, life-threatening side effects. The most serious side effects of Yaz and Yasmin include:
- Blood clots and deep vein thrombosis (DVT), blood clots in the body's deep veins, generally the legs, that impede circulation
- Breast lumps
- Gallbladder problems
- Heart attack
- Hyperkalemia, dangerously high levels of potassium in the blood
- Liver damage
- Pulmonary embolism (PE), blood clots in the lungs that dangerously impair respiration
- Stroke
- Symptoms of depression (sleeping problems, mood swings, lethargy)
Yaz Birth Control Symptoms
It is important for women taking Yaz to be in tune with the symptoms of potential injuries caused by the birth control pill. Signs and symptoms to be aware of include:
- Weakness
- Uncontrollable sweating
- Sudden numbness
- Vision problems or pain behind the eyes
- Migraine headaches
- Stomach pain or loss of appetite
- Sleeping problems, mood changes or other depression-like symptoms
- Heaviness in the chest or sharp pains
- Nausea, vomiting
- Swelling in your hands or feet
- Vaginal itching or discharge
Yaz Negative Side Effects
In October 2008, the U.S. Food and Drug Administration (FDA) required that Bayer HealthCare Pharmaceuticals, makers of Yaz and Yasmin, overhaul the advertising and packaging associated with the birth control pills. The FDA stated that Bayer's marketing campaign negligently downplayed the drugs' potential dangers, while at the same time, overstating its uses.
Although Bayer HealthCare has since complied with this mandate, many women have and will continue to be injured after taking Yaz and Yasmin as their form of birth control. Women who are harmed by severe Yaz side effects will likely have a legal claim against Bayer HealthCare.
About Yaz
Generically known as drospirenone, Yaz is a fourth generation oral contraceptive that has been FDA-approved for the treatment of moderate acne and premenstrual dysphoric disorder (PMDD), a debilitating type of PMS. Yasmin (generic: Ocella), also produced by Bayer HealthCare, is the only other form of birth control on the market to contain drospirenone.
The only difference between Yaz and Yasmin is that they contain a different amount of ethinyl estradoil, a bioactive estrogen that most modern birth control pills contain. Because they contain the same active ingredients, the side effects are similar. Given the severity of their associated side effects, it is recommended that women discuss their complete medical history with their doctor before starting a course of Yaz or Yasmin.
Who has the Highest Risk?
In most cases, Yaz patients will experience minor, if any, side effects, such as weight gain, breast swelling and/or changes in menstruation. View a more complete list of minor Yaz side effects, or consult a Yaz injury lawyer to learn about your legal options.
When serious side effects do arise, they typically affect women who have a history of:
- Abnormal vaginal bleeding
- Adrenal gland disorder
- Blood clots, stroke or circulation problems related to diabetes
- Breast, uterine or hormone-related cancers
- Heart problems
- Jaundice (caused by birth control pills)
- Kidney or liver disease
- Migraines
- Severe hypertension
Women who have experienced such health complications should work with their doctor to find an alternative form of contraception.
