User Reviews for Lactaid Fast Act oral

I tried these pills and within an hour or so I was vomiting. I thought it was coincidence, so I tried taking another pill several days later. Same thing happened, vomiting for hours after the pill.

I have tried this medication, as directed on the box for symptoms of mild lactose intolerance (bloating & gas pains as my biggest complaint.) I took this med and each time, about 1 hour after taking it I get a burning sensation/reflux then within the next couple hours I start to feel weak and then vomit multiple times.at first I thought it was coincidence but it has happened every single time.

My sister took the lactoid pills to help out with her lactose intolerance. She was fine for the first half but when it got later like around 11pm she started getting diarrhea and heavy vomiting for a good 2-4 hours straight. She reacts better without the pills than with them, I definitely don’t recommend these pills to anyone. 0/10 experience.

For the first few times taking it I was able to eat lactose products without feeling ill. However, I started to vomit every time I took them. Do not recommend whatsoever.

Took those twice to try to help with intolerance. Within an hour was vomiting to the point of dry heaving. Looked all over for this being a side effect but to no avail. Only able to find some confirmation on this page. Think this side effect should be listed with the product. Thank you for sharing your experiences here to help me find closure...

i take it because I DO stay bloated...this enables me to expel gas....and strangely enough,when taken with one "heartburn and gas" chew actually helps asthma symptoms....sounds silly,but i`m not kidding..i don`t know what exactly the interaction is but it helps... this stuff surely helps me..that,along with the fact that it has a very safe medical profile makes it a permanent staple in my medicine cabinet

The first time I took this pill was a couple months back to have some ice cream since I have some lactose sensitivities. After a few hours I was over the toilet vomiting and was bed ridden and chilled for the rest of the evening. Thought I just had a bug. Second (and last) time I took it was two weeks later. Exact same response. I don't recommend this at all.

Diagnosed with lactose intolerance my doctor reminded me that I could take a Lactaid FastAct pill and so that night, eating a homemade pizza with very little cheese, I took the Lactaid monster. It made me sick that night for three hours. I vomited violently and repeatedly and had diarrhea that was voluminous and uncontrollable. This is a very dangerous supplement. The makers of this supplement owe me a cleaning crew and a new washing machine. Shame on J&J for not providing this information on the warning label.Read More Read Less

The only issues I've ever had with lactase enzyme pills have been with not taking enough. It took me a while to figure out what dosage worked for me, depending on what I was eating, how sensitive my stomach was being, and what strength or brand I was using. I want to be clear about something, however -- Lactaid and lactase enzymes are in no way a cure-all. You may have a dairy allergy, and I doubt they would work for you, or you may be incredibly sensitive and no less than 9 doses might work. This is a supplement, not a prescribed drug, and you need to figure out for yourself whether or not it works. I personally have been taking lactase enzyme pills for nearly 4 years, and they have rarely ever let me down. Read More Read Less

My husband is on the bathroom floor writhing in agony for the SECOND TIME. The other time when he took the pills we were on a train in Italy and had to get off while he vomited for hours. Why is this on the market. It should carry a warning and the BS on WebMD that most people are just fine with it needs to have a serious caveat. MANY people have terrible problems on this medication. Lactose reactions are nothing compared to this foul medication.

I used to take lactaid pretty often and only had bloating as a side effect. I took some last night and woke up this morning vomiting and feeling sicker than I’ve felt in months. Do not use it!! There are plenty of dairy free options out there to keep you from using this.

I took this product two different times a week apart. The first time was followed by diarrhea, cramps and gas for a day. The second time resulted in five hours of intense stomach ache, vomiting and intense diarrhea for 4 hours. The next day I was still experiencing diarrhea and slowly improved.

Both times I used this, I got EXTREMELY ill, so bad that I thought it was a bad case of food poisoning. Intermittent vomiting within half an hour, lasting a full day the first time and several hours the second, with excruciating stomach pain that radiated into my ribs and back, nausea, fever, sweating. Persistent upset stomach, nausea, and body aches for over a day following use. 100x worse than just dealing with the symptoms of lactose intolerance!! I'll never use a lactase product again and I caution anybody thinking about trying them to schedule a test run where you don't have any obligations for the next day or two.Read More Read Less

PLEASE READ! This is a follow-up to my previous 1 star review. I have to say that I really don't know if this med is effective because today I learned that it is likely that I do NOT have lactose intolerance. My problem was coincidental to taking Lactaid Fast Act. I was diagnosed with gall bladder disease and my severe vomiting,cramps and diarrhea were due to a blockage in my bile duct. It was actually the fat in my meals and ice cream that lead to the symptoms and NOT the Lactaid Fast Act. Should I ever have a need for Lactaid I will certainly try it again. From the sounds of it many of the others with similar "reactions" should have explored this possibility. My apologies to the makers of Lactaid Fast Act.Read More Read Less

I like most reviewers here began using Lactaid Fast Act after feeling nauseous and gassy after drinking milk or eating ice cream. The first few times it really seemed to help. Around the 5th or 6th use the bloating and stomach upset seemed worse than without Lactaid so I thought maybe I should use 2 pills. Same result the first time taking 2 pills. The next time taking two pills I developed severe stomach cramps and vomiting two hours after using. I thought I had a virus or something. Three days later I again took 2 pills with ice cream and the reaction was even more severe, 6 straight hours of cramps, vomiting and diarrhea followed by another 24 hours of having itchy skin all over and feeling miserable with several more visits to the bathroom. I will NOT ever take this product again.Read More Read Less

The first hand full of times that I took these the worked wonderfully. The last two times i took this my stomach cramped horribly. The bloating was so unbearable It felt like my stomach was going to burst. Before i could tolerate a little bit of dairy, now I can't even have a tiny bite. Please don't take these. As I am sitting here cramping and bloated in pain. I wish I believed the other reviews.

My husband is lactose intolerant and takes Lactaid all the time. Milk has recently start bothering me so I switched to lactose free milk. I took one of his pills and a few hours later, I started vomiting and having diarrhea for hours, thought I was going to die. Had a similar experience last summer on a cruise, where I felt queasy, husband gave me one of his lactaid pills to 'help' and I spent the evening throwing up and having diarrhea! I thought it was food poisoning then, now I realize it was the Lactaid pill!Read More Read Less

I was diagnosed with lactose intolerance when I was 23 and just avoided dairy. When I got pregnant at 28, it pretty much went away. Now I'm 44 and having some dairy issues. Cramping and bloating after eating cheese and yogurt specifically. So I bought some Lactaid and figured I would give it a try. Within 2-3 hours after taking it, I got dizzy and nauseous and broke out in a cold sweat. I had violent vomiting and diarrhea for hours.I had trouble getting warm (but no fever) and had a headache. My husband wanted me to go to the hospital for fear of dehydration. I was thinking possible food poisoning since a friend who works in food service said that will often hit you out of the blue and be violent. I also was thinking possible stomach bug. But now it's the next day and I'm feeling better, but still weak and have not other "bug" symptoms such as feeling achy or fever. I'm still a little nauseous, but have been able to finally keep down some ginger ale. So I'm thinking it is the Lactaid. I seem to remember having some nausea when I took it way back when I was 23 and I only took one pill on one or two occasions. Yesterday, I took two with my first bite of dairy. I will NEVER take this again. Read More Read Less

The first time I tried this product it worked fine. The next time I tried it, I felt a weird sensation in my stomach. Did pay much attention to thinking it was the pasta I had for dinner. The third time I took it, I felt really sick. I am afraid to take it again.

Discovered my intolerance a few years ago, and then a friend told me about these pills. They worked the first few times and then just began to push my symptoms to a few hours out. The past two times I have been nauseated and bloated up to 24 hours after taking them. I'd take the side effects from eating dairy over the side effects from the pills, any day!
