Actor Dennis Quaid testified again on Wednesday, giving Congress, the details of a dreadful experience he had last year when his twin kids were accidentally administered with an extremely high dose of blood thinner, which almost killed them shortly after birth.

Quaid insisted that FDA approval of a drug or medical device should not keep states from suing the product's manufacturer and the patient’s option must be preserved to hold drug and medical-device makers liable for medication errors.

“Like many Americans, I believed that a big Problem in our country was frivolous lawsuits. But now I know that the courts are often the only path to justice. I believe if preemption of lawsuits is allowed to prevail, it will basically make all of us, the public, uninformed and uncompensated lab rats,” Quaid said at a House of Representatives committee hearing,

The lawsuit will be hears in the Supreme Court this fall, on limiting many personal-injury cases against drug companies that have won FDA approval. In February, the court defended medical-device manufacturers from many of the claims.

Quaid's twins, Thomas Boone and Zoe Grace, were reportedly given 1,000 times the required dosage of the blood thinner heparin at Cedars-Sinai Medical Center in Los Angeles, in November last year.

Quaid and his wife, Kimberly, sued, contending the heparin maker knew other infants had died as a result of improper labeling.

Citing the fatal risk to their children, Quaid and his wife, Kimberly sued Baxter Healthcare, challenging that the drug-maker was already aware of cases in which infants dies because of improper labeling on the drug-packs.

Baxter countered the claim and asked a judge to throw it out on a number of grounds, including the FDA's approval of its product.

Quaid responded to that, saying it would not be in the benefit of patients if FDA’s approval would cover the faults of drug companies like this. He urged to pass legislation to protect patients' ability to sue drugmakers if the Supreme Court further restricts the suits.

He added that a federal ban on lawsuits “would relieve drug companies of their responsibility to make products as safe as possible, and especially to correct drug problems when they are most often discovered-years after their drugs are on the market.”
