Yaz & Kidney Stones
Like many modern medications, Yaz has been reported to cause a range of mild to serious side effects, including blood clots, stroke and kidney stones. Kidney stones, clinically referred to as renal lithiasis, are small, crystalline mineral formations that form within the kidneys. Small kidney stones are not life threatening and typically don't require medical care, as they "pass" on their own. Larger kidney stones, as well as kidney stones that don't "pass", can result in significant kidney damage and, eventually, kidney failure.
Women who develop kidney stones after taking Yaz or Yasmin (generic: Ocella) will likely have a legitimate legal claim against Bayer HealthCare Pharmaceuticals and may be entitled to a settlement for their injuries. If you or a loved one has been diagnosed with kidney stones (or worse kidney damage) after taking Yaz or Yasmin, contact us to speak with a Yaz lawyer who can help determine if you qualify to file a claim.
Yaz Risk of Kidney Damage
While most Yaz patients will experience minor, if any side effects, severe Yaz side effects—such as kidney damage—typically only occurs in rare cases. Women who are at a greater risk are those with a history of:
- Adrenal gland disorder
- Kidney damage
- Liver damage
To minimize the risk of kidney damage, women should discuss their complete medical history with their doctor before starting a course of Yaz birth control.
Yaz & Kidney Pain
For those who decide to start taking Yaz, it's essential that they understand the symptoms of kidney stones so they know when to seek medical attention. Kidney stone symptoms include:
- Bloody, cloudy or bad-smelling urine
- Constant urge to urinate
- Fever and chills (when a kidney infection has developed as a result of larger or persisting kidney stones)
- Nausea and vomiting
- Pain in the side, back and/or below the ribs
- Pain that fluctuates in intensity within 20 to 60 minutes
- Pain that radiates from the side/back to the groin region
- Pain when urinating.
If you or a loved one has developed kidney stones as a result of taking Yaz or Yasmin, you should know that you have rights. For more information, contact a Yaz attorney today.
