Diabetes Drug Avandia May Cause Vision Loss

The diabetes drug Avandia®, the subject of numerous lawsuits concerning its possible link to heart problems, may also cause vision loss from macular edema, a condition in which fluid buildup behind the retina causes it to swell. Patients have reported new cases and worsening of existing cases.

Macular edema is the result of blood and protein leaking from blood vessels in the macula, the central portion of the retina. The fluid behind the retina has nowhere to go, so it pushes the retina forward from the back of the eye, causing distorted vision due to dislocation of the focal point.

Patients Report Symptoms after Taking Avandia®

According to the U.S. Food and Drug Administration (FDA), diabetes patients have reported to GlaxoSmithKlein (GSK), makers of Avandia® (rosiglitazone maleate), worsening of pre-existing macular edema and development of new cases. Most patients concurrently suffered from peripheral edema, swelling beyond the center of the retina, leading a reduction of peripheral vision. Some instances have been resolved by stopping the medication, which is used to control blood sugar levels.

Avandia® has been blamed for causing heart attack, heart failure, angina, and other heart-related health issues. The FDA has ordered GSK to print product label warnings that patients with a history of some heart conditions should not be started on the drug. Indications are that Avandia® may cause weakening of the muscles of the heart wall.

Other Possible Side Effects Listed On Label

Other possible side effects listed in label warnings include swelling of the legs and ankles, anemia, and hypoglycemia. Women are advised that taking Avandia® may expose them to an increased risk of pregnancy and bone fractures.

If you or someone you know has suffered irreversible vision loss due to macular or peripheral edema, heart problems, or other health issues after taking Avandia®, contact an experienced product liability/personal injury attorney. You may be eligible for financial compensation to help you deal with medical bills, loss of income, and other related expenses.
