For Lactose Intolerance "I just wish I'd read these lactase reviews before. I took a couple of tablets, over 2 days at the end of Sept and had 4 days' worth of severe vomiting and diarrhea. I didn't link the 2 at the time and figured I'd had a horrible tummy bug. Fast forward 2 weeks later, and I had a cheese fondue, so I took a tablet to avoid the bloating. Instead, here I am again with horrific vomiting, cramps, sweats, pain, and diarrhea. I was racking my brain, working out what I'd eaten or who has been sick recently in case I had caught something, then suddenly realized the only thing I'd done different was the medicine. Just Googled 'can lactaid cause vomiting,' and I got a sea of pages and people reacting the same way. I will never take or recommend this product to anyone again. I feel terrible, and I'm sad that this isn't more well-known as a side effect."

For Lactose Intolerance "The first few times I tried this product, lactase, I was fine, it helped a lot, so I offered some to my husband. I even bought more. One day, I became so nauseous, began vomiting for the first time as an adult. Threw up about five times, nausea continued, and the next few days diarrhea began. I thought it was a stomach bug. The next week, I took the pill again, and this time I became violently ill, the worst experience of my life! I began vomiting so much it sprayed on the floor and walls, then I began sweating and had trouble breathing, I had stomach pains and liquid diarrhea. I started getting chills. This was my night. I do not recommend these pills to anyone alive. HC and the FDA should be informed, and the manufacturers should not be allowed to make this product ever again. Judging from the other comments, I'm not the only one."

Lactase for Lactose Intolerance "I have tried these pills twice. Once last week, and I got violently ill, vomiting for 5 hours straight, and then diarrhea about 4 hours later. The vomiting was so bad that I couldn’t hardly breathe in between. I got cold chills and was sweating profusely. It was absolutely awful. I tried again last night, not knowing what exactly caused the illness the first time. Same exact thing. No way will I ever take another one of these or suggest them to anyone."

For Lactose Intolerance "I have very mild lactose intolerance, and for the most part it doesn’t affect my daily life other than getting a stomach ache after a particularly dairy-heavy meal. However, my girlfriend has it pretty bad, so we usually have this stuff on deck. A few days ago, we had a cheesy dish, and I thought to take one of these because it couldn’t hurt. An hour later, I was incredibly nauseous, had diarrhea, and even had a low-grade fever. I was so miserable I cried, but thought it was the stomach flu. I was fine for a few days, and then tonight I took a lactaid, and we are in this same position - nausea, diarrhea, cold sweats, etc. Something told me that maybe it was the lactaid, but after doing research, this was the ONLY website where people shared my experience. I will never be taking these again. Also, I know it’s not the lactose itself because this has NEVER happened before. Wish me luck as I take a Pepto-Bismol and try to ride this terrible night out."

For Lactose Intolerance "I’ve used Lactaid before and can’t remember having symptoms from it. I recently went on vacation and decided to buy some in case I ended up having any dairy. Looking back at just a couple of days ago, I understand why my stomach hurt and why I was nauseous. Today I had just a little bit of cheese and decided to take a Lactaid. I all of a sudden felt nauseous and had stomach cramps. I went on a walk and my cramps wouldn’t go away. I was getting chills and almost some cold sweats. Then, the diarrhea... It didn’t add up that my stomach would hurt that bad from half a slice of cheese. It sounds like so many people have experienced similar symptoms. I won’t be taking this again... I have tried the Equate brand and I don’t remember ever having issues, so I’m curious if there’s a difference in ingredients causing this problem. I’m too scared to try again now!"

For Lactose Intolerance "Tried these about six months ago, and within a few hours, was vomiting along with profuse cold sweating. Thought it was a bug or perhaps the pills were past their expiration date. Tossed that bottle and worked up the nerve to try them again. Big mistake. Two hours after taking them, nausea and stomach cramps set in. Vomiting and the worst diarrhea ever set in soon after. Will not be taking these again."

For Lactose Intolerance "I've been lactose intolerant for a few years, and the symptoms were worsening over time, so I thought I would use these before going to an Italian restaurant so that I could enjoy my food without my stomach and head hurting. Worst experience ever. It had been a long time since I was this ill. I was nauseous, had severe stomach cramps, and cold sweats. I actually couldn’t even touch my meal and had to leave the restaurant early. I thought I was an exceptional case until I found this page. Please do yourself a favor and don’t take it, and mostly, please don’t sell this garbage any longer, it’s just horrible."

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 ♥️"
