Serotonin Syndrome Lawsuits

Nadrich & Cohen is currently retaining serotonin syndrome victims.

It has long been known that certain drugs or drug interactions can cause serotonin syndrome, which can lead to serious symptoms such as kidney failure, shock or even death. However, sometimes pharmaceutical companies fail to warn about drug interactions on their labeling, and this exposes them to liability.

Call us now at 800-718-4658 if you or a loved one suffered from serotonin syndrome after taking a medication or combination of medications. You may be eligible for financial compensation. We won’t charge a fee unless we obtain a recovery for you.

How We Can Obtain Compensation For Your Serotonin Syndrome

We may be able to obtain a financial recovery based on numerous causes of action in a serotonin syndrome lawsuit, including:

Strict Liability – Failure To Warn

Strict liability – failure to warn can be the grounds for a serotonin syndrome lawsuit. FDA guidance says that companies, in their drug labeling, should “briefly describe any known or predicted drug interactions with serious or otherwise clinically significant outcomes and cross-reference to any more detailed information elsewhere in the labeling.”

The potential for serotonin syndrome to result from taking drugs or combinations of drugs has long been known. For example, the FDA, in 2011, warned about the potential for serotonin syndrome associated with drug interactions involving methylene blue, and warned in 2016 that opioids can cause serotonin syndrome by interacting with antidepressants and migraine medications.

We can hold companies liable for any injuries or other damages caused by serotonin syndrome if they knew or should have known that their drugs could cause serotonin syndrome alone or in combination with another drug and failed to warn about it.

Negligence

Negligence is failing to be reasonably careful to prevent harm. Those who harm others through negligence are liable for that harm in California.

Acting and failing to act can both be negligent. Failing to act when a reasonably careful person would act to prevent harm is negligence. A reasonably careful entity would warn on the product labeling about the risk of serotonin syndrome associated with their product when used alone or in combination with another product if they knew or should have known about that risk.
