For Lactose Intolerance "I love plain yogurt but was having difficulty with dairy digestion (diarrhea). So, I decided to try a generic lactase chewable tablet. What a mistake. I suffered severe nausea and could do nothing but lay in bed all day. Later, my daughter stopped by on her way home from work. When I told her I felt quite 'off' and what I had taken, she said: I remember when you tried Lactaid about 10 years ago; the same thing happened. I wish I had remembered. I will keep this last awful episode in mind."

Lactase for Lactose Intolerance "So far, Lactaid has been awesome. I've been using it for about a month. What my specialist diagnosed as GERD disease for the last 2-3 years appears to be acid reflux caused by my aging body's inability to produce the lactase enzyme to break down milk and milk products (I didn't realize how many food products have milk in them). In summary, my body couldn't break down lactose, causing acid reflux, and my specialist put me on a prescription drug. The first drug was pulled off the market because it caused cancer. The second drug (Rabeprazole or something similar) is still being evaluated. Anyway, no more pain in the upper left part of my stomach, no more GERD or acid reflux. I'm having a tough time believing my specialist didn't tell me about Lactaid or a similar product for the 3 years of pain I went through. I hope this helps someone else with stomach/intestinal issues. It's a known fact that 65% of aging adults will lose the ability to break down lactose."

For Lactose Intolerance "I have a pretty mild lactose intolerance usually. A big dairy meal can result in an upset stomach, cramping, and gas. I tried a lactase enzyme to hopefully relieve my minor symptoms. Upon taking the pill, my symptoms seriously escalated! I’ve tried it twice now, and both resulted in a terrible upset stomach, diarrhea, and vomiting. Googling the enzyme reveals no side effects, but after looking through these reviews, I’d recommend using it with caution!"

For Lactose Intolerance "I have mild lactose intolerance, so I decided to take some lactase before eating some mozzarella, which I can normally handle with only mild discomfort. Within 15 minutes of taking the lactase, I was nauseous and dry heaving into the toilet. Would not recommend. I tried taking it in the past as well with similar outcomes, but thought it was a fluke. Now I know."

Lactase for Lactose Intolerance "I have been taking Lactaid enzyme tablets for over 30 years, made from different manufacturers. I get a lot of gas from milk products. The tablets have controlled the gas with no side effects. I only buy whole Lactaid milk. I use the milk anytime regular milk is used. Lactaid tablets or milk do not work for my brother. I have to take twice the normal directed dose for the pills to work for me. The price is high, taking twice the dose, therefore, 9/10 rating."

Lactase 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 "Do yourself a favor and don’t buy these pills. They won’t help you and only give you false hope. I tried these pills out in an attempt to help me wean dairy out of my diet since I usually get an upset stomach when I eat it, but I figured I could treat myself every once in a while by using these. They worked for the first 4-5 times, and then I took two to eat a pizza. Worst mistake of my life. I ended up running to the bathroom and nearly pooping my pants and then projectile vomiting eight times into my bathtub. I seriously felt like my stomach was just a super soaker full of stomach acid and pepperoni. At the time, I figured I had just gotten food poisoning, so I took another one tonight in order to eat an ice cream cone. Tonight is when it clicked that it was the pill, I’ve been toilet-bound for the last three hours and once again find myself vomiting into my tub. Please do not buy these. Save your money and try other milk alternatives if you can."

Lactase for Lactose Intolerance "Okay, so I’ve been suffering from undiagnosed stomach problems they wrote off as IBS, and well, I’m not buying it. But point is, they tested me, and it showed I was lactose intolerant. So, me being the person I am, I didn’t want to upset my stomach more, so I bought Equate lactose pills. At first, I took one or two and no problems, although I never had horrible discomfort from dairy anyway, just the occasional runs. But BOY WAS I IN FOR IT! So, I took 3 lactose pills because 'no side effects,' right? WRONG. That was my first warning because a couple hours later, I felt like I was going to vomit, and that feeling lasted two days. But I figured it was what I ate. SOO, fast forward to last night, I ate mac and cheese at 2 AM, and me being scared it would hurt my stomach, I took 3 lactose pills. And THE NEXT MORNING, I WOKE UP IN PAIN, and I ended up vomiting for the first time in 4 years. So no more pills (figures because I ate nachos and fried mac and cheese prior with no pills, and I was fine)."

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 "So good to know I’m not the only one. Every time I use this product, I immediately get nauseous. I guess I’m going to have to do things the hard way and stop my dairy intake. It is definitely worse taking the Lactaid than being serious about my intolerance. They need to change the official side effects. I believe they get away with saying there are none."

Lactase 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."

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."

Lactase for Lactose Intolerance "After discovering that all medications I was taking had lactose in them, also finding out I was taking the wrong Lactaid, I found that I must use the fast-acting kind. My problems have all but disappeared. I can tolerate some sharp cheddar cheese. When eating out, I take 2 fast acting at every meal because, like it was said before, lactose can hide in a lot of places. I can have a lactose-free meal at home and still have to take 2 Lactaid because of warfarin I take that has lactose as a filler. My stomach is much better because of Lactaid."

Lactase for Lactose Intolerance "I've been lactose intolerant since I was a young child, but I never took anything for it. I avoided regular milk and have only used Lactaid milk or soy. A couple of weeks ago, I decided to try Lactaid Fast Acting pills because I was tired of the gas and upset stomach. This medicine has caused me severe stomach pains and diarrhea. I am currently curled up in a ball in pain. I would rather have terrible gas than take this pill again."

For Lactose Intolerance "I tried lactase inxe while pregnant and ended up vomiting profusely. I chalked it up to pregnancy woes. Just tried it again (over a year later, obviously not still pregnant). I have been vomiting so intensely that my 3-year-old is terrified. I'm experiencing abdominal cramping, sudden diarrhea, and horrible retching. FAR sicker than I would have been just eating the dairy alone."

For Lactose Intolerance "So after numerous times of taking these pills and becoming extremely nauseous, I’m now Googling and finding all you guys experiencing all the symptoms I’m having. Gosh, I wish I could’ve pinpointed it earlier, it just didn’t dawn on me sooner. Wow, so many testimonies all the same. I threw my 60 tablets in the trash, never again. Lesson learned."

Lactase for Lactose Intolerance "I've been unable to eat ice cream since my teens without getting sick. Other dairy was fine until I was recently diagnosed with an autoimmune disease. I got so sick each time I ate it. I was fully off it until I found these. Not only can I eat dairy again and not get very sick, it helped fix my IBS symptoms. No idea how that happened, but I'll take it."

For Lactose Intolerance "I just got done throwing up three times from this product. I have used this maybe 5-6 times, and it has always worked until tonight, where I had a milkshake. I had an upset stomach the entire night and threw up pink cheesecake milkshake. I'd rather have it come out of the other hole instead of my mouth. This product is awful and needs to be removed off the market. I’ll stick with almond milk."

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."

Lactase for Lactose Intolerance "I am mildly lactose intolerant and have used Lactaid brand milk for several months without issue. Suddenly, one day after ingesting this product, I became violently ill with extreme stomach pain and vomiting. This occurred almost immediately and lasted for nearly 10 hours. I was fairly certain that I was experiencing a reaction to the Lactaid product for a number of reasons. I think most people experiencing this level of pain would have rushed to the emergency room. Don't ingest things your body can't process, regardless of what they tell you."

I vomited everything up, had aches and pains, almost passed out. I’m so glad I realized what it was the second time and will never use it again. I’m annoyed that this info isn’t more widely spread, as I would never have used it if I’d known this."
