Lactaid Fast Act Lactase Enzyme Supplements, 72 Count

Within 5-10 mins of taking this, my stomach wasn't feeling well. I started to get severe stomach pain and felt very nauseous. Soon after, I started vomiting. I still feel nauseas and still have bad stomach pain. I do not recommend this!

My daughter was diagnosed with 0 enzymes. Yes, ZERO. After cutting out all dairy from her diet for a year (and you would be surprised how mostly everything contains dairy) she was able to slowly re-introduce dairy by taking Lactaid fast acting pills. Now she can enjoy dairy... ice cream, glass of milk...

I don't know if it's just the Fast Act lactaid or what, but every single time I take one, I get severe upper stomach pains, like doubled over ready to cry pain... And really really bad nausea. Not sure why. But I'm done with these. I'd rather have the diarrhea.

Have used twice, and both times within half an hour I go from feeling fine to severe stomach pain and vomiting. Fortunately, after it's all vomited up, I feel pretty normal again. That's not exactly the way I hoped to avoid lactose intolerance, as just not eating milk products to begin with is much less painful. The one and ONLY reason I would use these pills is if syrup of ipecac is not available, and I need to vomit. It's a sure thing for me (and apparently many others), and this might actually work quicker! Not having a warning label on this product is truly inviting a class action situation. You guys are WELL AWARE of this problem by now.

gave me nausea and severe diarrhea for weeks before i realized it contains mannitol polyols. Pls don't put mannitol in anything!

There are no directions printed on the box for the Lactaid Fast Act Caplets nor on the individual caplet packets as to how you should take this. For example it does not say if these should be swallowed or chewed.

I took this one time and was fine, the two next times I took this i vomited like others within 30 minutes of taking this product. Why this is not. Listed side effect of taking it.

I bought this 2 days ago and took 2 tabs around 4p to have with ice cream. I woke the next morning with a splitting headache, dry mouth/swollen salivary duct under the tongue, severe nausea and vomiting (dry heaving). The headache and nausea/vomiting were so severe I couldn't not keep down water nor sit or stand. I had to miss work and “doze” all day bc of the pain and discomfort. Able to drink sips of water that night. Next morning feeling generally unwell but able to keep down water, broth, rice crackers etc. Product not recommended. Take with extreme caution.

I have always been lactose intolerant but have always been able to tolerate diary products with minimal symptoms. As I have grown older (I am 54 now), my lactose intolerance has gotten worse: painful cramps, bloating, gassiness, diarrhea/constipation. I started taking Lactaid Fast Act Caplets about a month ago and ALL my symptoms have gone away. What a life saver for me! Now, I carry the caplets with me in my purse and lunch bag at work. Plus I love that the dose is ONE caplet per meal instead of 3 tablets!

These symptoms need to be listed as a side effect. The first time took lactaid I had sudden onset of vomiting and diarrhea which I thought was caused by food poisoning. The second dose I experienced nausea with abdominal cramping. I do recommend this product because I've used other Lactaid products which helped control my lactose intolerance issues. The product needs to be taken with caution.
