Erin Foster says she had suicidal thoughts after taking Tamiflu

Erin Foster, the 36-year-old daughter of David Foster, recently took to social media to detail her terrifying experience with Tamiflu, an antiviral medicine for treatment of the flu. 

The comedy writer and actress, who has appeared in shows like "NCIS" and "Law & Order," described having a clear voice in her head prompting her to kill herself despite never having suicidal thoughts in the past.

"Sorry to get dark, but I'm gonna share this uncomfortable story because it's important for you to know for yourself and your kids," she began in a series of Instagram Stories.

"I've never had a suicidal thought or tendency in my life. About 7 years ago I was prescribed Tamiflu for the flu. On the third day, I woke up in the middle of the night drenched in sweat with the clearest voice in my head that I wanted to kill myself," she wrote.

"It made no sense. I didn't have a reason, I felt like I was losing my mind. I laid on my floor panicking and feeling like I needed to stop myself but I didn't know how. I genuinely thought I was going insane. It  was the scariest thing I've ever felt."

Foster continued to say she never thought it could have been caused by a medicine but she was able to push through it, although it eventually lead to panic attacks.

"I obviously was able to push through it and wait for the feeling to go away, but I was f--ked up for weeks. I kept having panic attacks, which I had never had before...I know with perfect certainty that this was solely because of Tamiflu."

She concluded her story, "If my doctor had warned me this was a potential side effect I would have known what was happening. And there are teenagers who actually did kill themselves on it. Happy, perfect kids, who took Tamiflu and then committed suicide and now they're claiming there is no link between the two."

Although studies have debunked direct correlations between Tamiflu and suicide, the U.S. Food and Drug Administration requires a warning on Tamiflu packaging that it "may cause hallucinations and delirium in young patients and make them more apt to hurt themselves or take their own lives," according to Web MD.

Foster also continued to share a wave of support via messages that came through after sharing her story.

One mother shared "I had no idea about any of this either and my 3-year-old daughter woke up after day 3 screaming on top of her lungs in a complete daze and I could not get her awake or aware that I was there. It went on for days even when I stopped the meds. It was horrifying."

Another wrote "I'm really glad you shared this as I just went through a horrible reaction with my son and this drug."

If you or someone you know is struggling with suicidal thoughts, please call the National Suicide Prevention Lifeline at 800-273-8255.
