For Lactose Intolerance "I took the chewable Lactaid on three occasions. The first time, I had to miss work for the remainder of the day as I was vomiting nonstop. Next time, the same. The third and last time, I ended up in the ER, I was in pain, had a fever, diarrhea, and vomiting at the same time. My wife was the one who recalled that all three times I was sick, it was when I used Lactaid Fast Act chewable tablets. NEVER AGAIN. I did not believe it, so I tried eating the cheese I had that night without Lactaid, and I did not have any symptoms except the usual bloating I get from lactose. I prefer bloating to spending a night hooked to the intravenous fluids."

For Lactose Intolerance "This is the first time I’ve bought this brand, and the rest of the stories sound very familiar. I took 1 pill and ate 2 slices of pepperoni pizza, and I was in the toilet with cramps all day. Then tried 3 pills. Same. With 2 slices of pizza, and nope, it did not help. I felt cramps, so much bloating, and constipation, then diarrhea. What a bad experience!! I thought this would help me, but no. Do not recommend this brand. I bought it at CVS."

For Lactose Intolerance "I have been using Lactaid milk for a while for my morning cup of coffee and still had issues with bloating and gas, so I recently decided to use the Lactaid Fast Act. I noticed that there were days when my stomach would hurt an hour or two after the pill, but nothing too insanely bad. But today, I only drank my coffee and one of the pills, and three hours later at work, I was in a cold sweat and puking my life away. I hate leaving early, so it was super embarrassing, and when I got home, I felt the same stomach pain I usually get from the Lactaid pill, and additionally, I started having really bad diarrhea. This pill was supposed to make me more comfortable, but I almost puked all over my coworkers and pooped to within an inch of my life at home. I'm hesitant to ever take these again."
