I wouldn’t be who I am without this product!

This product works for those who struggle with dairy. Lightweight and easy packaging. It works and helps me forget that I struggle with dairy! Would recommend

Box has no instructions on how to take the caplets

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.

Made me sick after taking it.

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.

Horrible adverse reaction

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.

Absolutely a lifesaver for dairy lovers like me!

I’ve been lactose intolerant for years and always had to avoid my favorite treats like ice cream, cheese, and milk-based dishes. Ever since I started using Lactaid Fast Act, it’s been a game changer. I just take one right before my first bite, and I can enjoy dairy again without the awful bloating, gas, or stomach discomfort afterward. The packaging is super convenient—especially the individually wrapped tablets. I keep a few in my purse, car, and even my kitchen drawer. No more guessing or skipping out on dessert! The taste is totally neutral—no weird aftertaste or chalkiness. You can swallow them easily, and they don’t leave any lingering flavor, which is a big plus for me. Also, the value is great! You get 60 caplets per box, and since I only need one per meal, it lasts a long time. If you’re sensitive to dairy, this is a must-have. It actually works—and fast.

Causes severe vomiting!

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.
