For Lactose Intolerance "Right now, I feel very, very sick. I just took 3 extra strength Lactaid pills, then ate a small creamsicle. I was convinced my lactose intolerance must have increased to a new level because I am severely bloated and nauseous. Now that I read these reviews by my fellow sufferers, I see that the Lactaid failed to protect me."

For Lactose Intolerance "I used the Lactaid chewable tablets for a good two weeks. Everything was fine until a few days ago when I took it and got extremely sick, sicker than I've actually ever been in a while. I had uncontrollable diarrhea for 2 days, horrible nausea, couldn't eat anything besides cereal without instantly triggering the diarrhea and insane nausea. I've now gone three days without taking this, and I'm feeling significantly better. These symptoms are worse than what I get by just eating dairy on its own, so I guess I'll just take my chances with that. This product needs to be recalled."

For Lactose Intolerance "My mom bought these for me a while ago. I was hesitant to try, as I’d read some pretty bad reviews. I have lactose intolerance, it’s not life-debilitating (usually just gives me diarrhea or stomach pain), but sometimes I just want some dairy! So finally, a few weeks ago, I gave them a try. They worked, so I tried them maybe 3 other times. Then, last week, oh man. I tried them with my dinner (pasta with creamy sauce), and 2 hours later, when I got home, I had severe back pain, nausea, the shakes, etc. I vomited for the first time as an adult. I had about 3 sessions, puking 10 times altogether, and diarrhea too. I thought I had food poisoning! Fast forward to today, a week later, I wanted cheese, so I had lactaid again because I figured my illness was from food. Exactly 2 hours later, my back began to hurt, and I ended up experiencing the EXACT same thing. I’m sitting here now, still shaky. DO NOT USE THESE. This is 10,000 times worse than ANY effect I’ve had from dairy. Feel better, everyone."

Lactase for Lactose Intolerance "After taking 1 dose of lactase enzyme supplement 9000 units along with some ice cream, I felt sick to my stomach. I had stomach pains, nausea, just an overall feeling of sickness which lasted for most of the day."

For Lactose Intolerance "The first time I took this pill, I didn't experience any side effects. Then I took the chewable a week later, and I had the worst experience that I have had in my life! I was extremely nauseous, weak, shaking, had the chills, and had severe diarrhea. I thought I had gotten sick or something, so I tried the pill again, this time, the side effects were way worse and extreme. I was vomiting so badly, had stomach cramps, couldn't sleep from the pain, weak, shaking, I felt like I was going to pass out. I would recommend this product to anybody."

For Lactose Intolerance "I've been trying these out for a change because I missed eating cheese. It seems to have worked well, so I have been taking them for about 2 days straight (about 2-3 each time). I've been getting small bouts of nausea. I'm writing this because I just ate another one with a pizza, and all of a sudden I felt a strong wave of nausea come over me. Like I was going to throw up, and my stomach upset. I wanted to go to sleep, so I grabbed a bucket. It is a weird sensation. And all day I feel like I have a stomach bug. I didn't link anything until I Googled lactaid and vomiting. I'm disappointed."

For Lactose Intolerance "After giving my son this pill and sending him off to school, we received a call within 2 hours that he was throwing up with chills! His body temp dropped. After vomiting within a few hours, he was okay, we didn’t put two and two together until tonight. Prior to eating, we gave him the pill again, and sure enough, two hours later he is vomiting and extremely nauseous. We did a search on the pills and are shocked to see so many other people dealing with the same symptoms. My wife actually said one of the ingredients is another name for formaldehyde! I don’t know how this stuff is on the shelf, and I’m extremely upset over it! Something needs to be done to stop them from continuing to sell this and cause harm to others!"

For Lactose Intolerance "I've been lactose intolerant since my early 20s. I used to take lactase back then and thought it just didn't work well for me. Then one day I took some and ended up vomiting up the ice cream I ate. I figured my intolerance was just that bad, and I've avoided dairy entirely since. Recently, I ordered dairy-free dip, and my shopper accidentally grabbed the wrong one. I eat cheese with no issues and thought, maybe I'll get some lactase and try with this, so it doesn't go to waste. I took 2, ate some dip, and felt bloated and nauseous after. I thought, maybe I just need to take more next time. Horrible mistake. It's a few days later. I took 4 and ate some dip and I've been violently ill since. Vomiting, cramping, nausea, diarrhea...I've not been this sick in years. I will never touch lactase again."

For Lactose Intolerance "I took a few OTC lactase enzyme tablets, and I had diarrhea and vomiting. The doctor thought it was due to food poisoning, then maybe COVID. After having had COVID, I went out at lunch, took lactase again, and was nauseated, violently vomited, and barricaded in a public restroom. My husband called an ambulance 45 minutes later because I was weak, vomiting, shaking, and couldn’t stand, and my complexion was strangely bluish. At the hospital, I shivered uncontrollably, with no temperature (I note others mentioned this symptom). After a hospital exam, including an unremarkable ultrasound of the abdomen, I was released. To diagnose the cause of vomiting, my PCP referred me to an allergist who said the sudden, eruptive vomiting and shivering had not been an allergic reaction but could have been caused by lactose intolerance. So I tried full-dose lactase again with dairy. A few hours later, acute nausea led to sudden vomiting. Concerningly, some lactase supplements have 80% negative reviews here, which may indicate either new or undisclosed side effects."

For Lactose Intolerance "Do not take Lactaid. When I first ordered it, I was really hoping I had found the cure to my lactose intolerance, but after using it a few times and feeling bad both times, and ultimately puking my guts out today, I have learned this drug doesn't work. Don’t waste your money on it."

"Ate a bowl of cereal with about a 1/2 cup of Lucerne whole milk and was nauseous, weak, and had severe body aches (primarily along the spinal column) within 10 minutes of finishing. Read the label (my roommate bought it because it didn’t have carrageenan in it - my body does not like carrageenan either) and it contains “lactase enzyme*” *an ingredient not found in regular milk. Something new to avoid."

For Lactose Intolerance "Violently ill each time I've tried it. Takes about 2 hours, then severe nausea kicks in. And then the projectile vomiting, along with explosive diarrhea - at the same time! Spent hours on the toilet with a puke bucket in my lap. Terrible stomach pains, chills, weakness too. Awful, awful. Trashing the rest of the box."

For Lactose Intolerance "Was recommended lactase tablets by a friend that seems incredibly lucky that they don't have side effects. I took one pill before having some ice cream and spent the next day with the worst stomach cramps, nausea, and diarrhea that I've ever had. It's now 6 days later, and I still have a slight stomach ache. This is awful, do not ever take these pills."

For Lactose Intolerance "Oh wow!!! Horrible! The gastroenterologist told us to get lactase dairy relief pills for our 13-year-old daughter. Three weeks later and she's been so much worse than ever. I started trying to figure out why she's vomiting and feeling constant nausea. Finally down to these lactase pills and I am so glad I found this site!!!!! We are stopping them today. Unfortunately, she already took some this morning, so we're going to have another bad sick day... :( The pains and vomiting are terrible... This is awful."

Lactase for Lactose Intolerance "Took 2 chewable lactose tablets approximately 4 minutes prior to having sausage gravy with milk. Before I took my first bite of food, my abdomen was bloated with gas (we're talking 45-60 seconds of flatulence). This is worse than just having milk. Nausea accompanied, within another 8-10 minutes, and diarrhea within 30 minutes. I'd taken it before and it worked about half the time. One thing to note: I am on a carnivore diet for the past 4 years, so my gut biome is drastically different than what it used to be. Without taking Lactaid and staying away from milk products, I do not have gas ever. Nor do I get diarrhea. I am strict on this diet. I had no biscuits with this meal, only eggs and sausage gravy made with milk, but the symptoms started before my first bite of food and only after taking the medication. So there's an anecdotal correlation and only a possible causation. More studies should be done."
