For Lactose Intolerance "Absolutely awful pill, do not take. Last time I took this, I threw up for hours on end and felt terrible-I thought I had food poisoning or a stomach bug. Turns out it is just these pills, and I'm currently fighting the awful side effects of this terrible pill."

For Lactose Intolerance "My fiancé is lactose intolerant and took this before a birthday party so he wouldn’t have an issue with whatever food was being served there. He has been vomiting for 4+ hours, as well as diarrhea. At first, we attributed it to alcohol, but we both ate/drank the same things, and I was fine. DO NOT take these pills! They are more hurtful than helpful!"

For Lactose Intolerance "I have never been so sick in my life after taking these. Took some a few nights ago, ended up violently vomiting for about an hour, just about went to the hospital. Tried this morning again because I wanted a cappuccino. BIG MISTAKE! Sick again! With chills this time as well! I will NEVER take this again!"

For Lactose Intolerance "Like others, I wish I’d seen these comments earlier. I’m new to lactose intolerance, but nobody mentioned the treatment could be worse! So yeah, I had ALL the experiences above twice in the last week (have had a COVID test today as a result) & the only thing that lines up is the use of this drug to counteract dairy! Vomiting, diarrhea, chills, sweats, legs went out from under me, the works! Convinced I had food poisoning the first time, the second time (today) figured it HAD to be COVID… until I saw these comments. Thanks everyone for baring your souls & sharing your horrors so that I don’t feel alone ♥️"
