These labeling changes are based on a safety evaluation of preclinical, clinical and post-marketing information.

What are some warning signs of liver failure?
Warning signs of liver failure may include, but are not limited to, nausea, vomiting, abdominal pain, fatigue, loss of appetite, dark urine, or generalized skin and eye discoloration.
If I develop heart or liver problems, do the warning signs happen while on drug treatment or can they develop years after stopping treatment?
Based on data known at present, the warning signs are most likely to be present while taking the drug or soon after stopping it.
Are there other treatments for my nail fungus that are safer?
No drug product is "perfectly" safe. Every single drug that affects the body will have some side effects. For every drug FDA approves, the benefits are balanced against its risks. In addition, FDA makes sure the labeling (package insert) outlines the benefits and risks reported in the tested population and is updated, as new information becomes available. You and your healthcare professional should decide together if the benefits outweigh the risks for YOU based on the new safety information for Sporanox and Lamisil. The new labeling for both Sporanox and Lamisil recommends that healthcare professionals obtain nail specimens for laboratory testing to confirm the diagnosis of onychomycosis before prescribing the medications for this indication.
What actions have the FDA and the manufacturers taken to make the public aware of this safety information?
The FDA has worked with the manufacturers of Sporanox and Lamisil to revise the professional labeling to inform health care providers about these possible serious side effects, describe the types of patients that should not receive Sporanox or Lamisil, and explain when Sporanox or Lamisil therapy should be stopped and distribute a "Dear Health Care Professional" letter which the manufacturers will send to health care providers to convey new information on safety.
What should I do if I am currently taking Sporanox or Lamisil?
Tell your doctor about any side effects you experience while taking Sporanox or Lamisil. Any decision about which drug product to take to treat your nail fungus should be made in consultation with your doctor based on an assessment of your specific treatment needs, specific risk profile, and other factors.
Should I contact an attorney if I experienced severe side effects after taking Sporanox or Lamisil?
Perhaps. It may be important for you to contact an attorney who can help you protect your legal rights. Only a licensed attorney can evaluate whether you have a case worth pursuing. Keep in mind however that there may be time limits (Statute of Limitations) which affect your ability to sue.
