Lactaid Extra Strength (lactase) for Lactose Intolerance "In the 20 years I’ve been with my husband he has never vomited once. He tried Lactaid to help curb other stomach issues with dairy. Used it twice and was fine. The third time he tried them before a slice of plain quesadilla and projectile vomited all over a hotel bathroom and was ill/sore for DAYS. We thought it was food poisoning until he tried them again and same thing, needed to vomit, gas, bloating, diarrhea. Horrible, these should come with a warning."

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 ♥️"

For Lactose Intolerance "Oh wow!!! Horrible! Gastroenterologist told us to get lactase dairy relief pills for 13 year old daughter. 3 weeks later and she's been so much worse than ever. I started trying to figure out why she's vomiting and felon 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."

For Lactose Intolerance "The first time I took this pill I didn't experience any side effect. 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 got sick or something so I tried the pill again this time the side effects was way worse and extremely. I was vomiting so bad, 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 "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 "As sorry as I am to see so many have had severe vomiting, it's comforting to know that I'm not alone. I had a horrible experience with vomiting and the runs after taking Lactaid. That said, I don't agree with those calling for it to be taken off the market. My son uses this a couple of times a day, if not more, with no issues. His diet is heavy with dairy (for reasons that I'm not going to explain) and these pills have made it possible for him to eat. I'm glad they exist for him. I will never take another one, but they can be good for many people."

Lactaid Fast Act (lactase) for Lactose Intolerance "I have suffered (severe dyspepsia) from eating dairy since my early years in life. At a friend's recommendation, I tried Lactaid tablets. All I can say is this little pill has changed my life. For the first time in decades, I can enjoy cheese and ice cream. This little pill has given me the ability to enjoy foods that I never thought I would eat again in my lifetime. Thank you!"

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 eat/drank the same things and I was fine. DO NOT take these pills!! They are more hurtful than helpful!!"

Lactaid Fast Act (lactase) for Lactose Intolerance "I have been on the milk ever since it came out. It was a blessing for me because I am a milk drinker. I took the pills before the chewable but when the they came out I was thrilled at how fast they worked and they are good tasting so what could be better?? Not a thing. Thank you and to who ever came up with the chewables. I would like the coupons. "

Lactaid (lactase) for Lactose Intolerance "I have become very sensitive to lactose. Although I only eat low lactose food such as cheddar cheese, parmesan cheese, yogurt it was causing severe gastric problems that were hard to pinpoint. After a few cheesey and yogurty days, I realized the association. Lactaid got me through those leftovers. Now I take Lactaid whenever eating food I don't prepare and I am symptom free. No negative side affects. I will use the little travel case when eating out. I won't be eating dairy like I was but using Lactaid gives me assurance. After struggling for years, Lactaid is a sweet solution.:-)"

Lactaid (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."
