"I sure hope me writing this can help someone avoid the prolonged agony I experienced on Trintellix. I started with a 5 mg dose for one month. After about 5 days, I started having itching on my external vulva.  By the 7th day, I almost went to the ER, but by that time, due to all my scratching, I had developed a pseudomonas aeruginos infection. Four courses of antibiotics later, the unbearable, constant, relentless, and ever-present itching was still there, with some hives. Though the infection was gone, the itching continued. I have never had intense itching like this--the more I scratched, the more I itched, and I couldn't even sleep. Two days after stopping Trintillix, the itching was gone. Two months of hell. Fixed drug eruption."
