There are actually two components of milk that one can be allergic to - the protein (casein) or the sugar (lactose). My daughter was allergic to the protein at birth, and we (pediatrician & I) knew it was the protein not the sugar, b/c mother's milk is super high in lactose, albeit human lactose and not cow but still is lactose. All babies born into the world have lactase to break down lactose in mother's milk. But some of us must have stopped producing lactase. Wanting my kid to be normal and eat Goldfish, mac 'n cheese as other kids, I tested my daughter at 12 months with Lactaid milk. Diarrhea right away, just like with infant formula. Same thing at 18 months, and at two, I tested her with cheese and organic whole milk. Again, diarrhea. HOWEVER, the only thing she can eat is RAW CHEESE. I would test her on raw milk too if it was legal in my state, but it's not. So my conclusion is this: those who cannot tolerate dairy products or Lactaid may be allergic to casein or milk protein as well. From what I've read, cow milk proteins are very hard to digest, not truly meant for human consumption as much as for cows and calves not only drink the milk raw from mama-cow replete with enzymes but they have four stomachs to help them digest the milk, proteins and sugar and all. This is why some of us have better luck with raw milk (even without 4 stomachs) and why many of us eventually have problems with commercially sold milk from the supermarket that's pasteurized even if we didn't always have problems with it.

The plot thickens.......... and I think I may be on to something here! I've been taking a protein supplement for the last two months or so. For the first several weeks I didn't experience any major side effects from it. More recently, within the last couple of weeks, about 15 min. after I take it I begin to have sharp pains in my stomach with nausea. The pain and discomfort is radiating, comes and goes. It lasts for about 10-15 min. and then disappears almost as suddenly as it comes on. I hadn't even noticed it before but one of the ingredients in this protein powder is....... wait for it........ wait for it............ any guesses?.............. wait for it.............. Lactase enzyme! I feel like Sherlock Holmes! LOL Now I'm convinced that I'm correct. If any brave soul who has had a bad experience with the tablets would be willing to try the milk, where the Lactase has already converted the Lactose, I would be very interested to hear about the experience. My guess is that the side effects would be substantially reduced in intensity if not virtually non-existent. So....... since I was first, who is going to be second?

I haven't read through every single one of these but out of the couple of dozen I have, it seems like all of the issues are with the Lactase enzyme in concentrated pill form. I'm just curious if anyone has experienced these same violent side effects with the Lactaid milk. I've been using the milk for several weeks now and admittedly do experience some VERY mild nausea that I can almost certainly attribute to the Lactaid milk. Otherwise though, I have to say I have not had any of the violent pains and vomiting many others here have complained of.

I'm just wondering if it's not only the enzyme that's causing the problems but could it possibly be the actual process of the enzyme converting the Lactose sugar in the body that is causing the side effects. I'm just kind of thinking(typing) out loud here but........ I wonder if many of you who have complained about these violent symptoms would actually experience them with drinking the Lactaid milk vs. taking the pills. Only because with the milk, the process of the enzyme converting the Lactose has already occurred.

Would anybody be willing to give this a shot just to see if there would be a difference?

My 12 year old son had a lactose intolerance and because he loved dairy - especially skim milk, mac and cheese, ice cream - we decided to help him with the intolerance side effects of diarrhea, cramps, gas - and try the store brand of lactaid. The ingredients were identical to the brand name. the pills & worked great for about 3 weeks. This past week, he had horrible stomach pains, diarrhea again and nausea, so bad he had to miss school. He had an appetite, no fever, but was assaulted with the side effects from taking the lactaid pills. I thought I was helping him, yet only the reverse! I am grateful to have come across this web site and shared blogs. Now I know how to solve my son's problems that caused so much suffering. In addition to the stomach pains, diarrhea & nausea, he also complained of bad headaches. As a mom, my instincts are correct and I attribute all of this to taking the lactaid pills. Thankfully, my son will not have to endure the horrible episodes anymore. Lactaid pills are banned from our home!

I have severe lactose intolerance and Lactaid helped me immensely for about a month. I was able to eat anything I wanted and felt great afterwards. Well, recently I've been having episodes where I've been sick to my stomach, doubled over in pain, etc. I didn't know what the problem was. There was no vomiting but a very, very sore and sick stomach. Tonight, it clicked that it was the Lactaid. So I took it again with dinner and here I am right now, 7 hours later, sick to my stomach for the past 4 hours. I feel like I need to vomit and the feeling is taking forever to pass. It's terrible. I will never EVER take this stuff again.

I recently began giving my 11 yo lactaid (store brand) because we noticed he had a problem with gas and diarrhea after eating dairy. Tonight he had 2 tablets with dinner and about 2 hours later complained of his stomach hurting. He sat in misery for about another hour and a half until he finally vomited. He also had diarrhea. He seems fine otherwise (no fever, doesn't feel "sick") and after reading all of these stories after doing a search I'm thinking that this must be what it is. I feel terrible as a mom giving it to my child and making him feel so horrible!

Like many of the others who have posted to this site, I have been dealing with what I thought was IBS for the past 3 years or so. I'm healthy and mid-30s and couldn't figure out what was causing it. Colonoscopy and other tests showed that all was normal. I don't drink caffeine, coffee or alcohol. Healthy as can be. Finally discovered it was a dairy intolerance. Coming off dairy solved the diarrhea issue but really limited my diet. Shortly after I discovered Lactaid Fast Act supplements and started to take them at meals when I had dairy.

For the first three weeks, the pills worked great. I loved them. I could eat like normal again without diarrhea. But after that time, I started to feel a sharp pain in my stomach when I take them...like someone slugged me in the stomach. It always comes within 5 minutes of taking a pill. Since then, it has gotten worse. Gas, bloating, and a constant pain (gnawing feeling) in my stomach that nearly has me doubled up. I've never had an ulcer, but from what I've read, that's what it feels like. I decided to stop using the pills.

I just discovered this site and was amazed to see that others have had the same. I should have checked for side effects before I took it! I've not had the vomiting that many of the others have had, but I won't be taking it any longer and risking that!

Hoping there is some alternative solution out there. Hard to imagine the rest of my life without cheese or dairy in anything (bread, dressing, etc.).

I started drinking Lactaid milk this past Saturday - one bowl of cereal a day with milk on it. I have developed a rash on my upper body - chest and back. It does not itch just red little bumps. Has anyone else experienced this reaction?

After struggling with IBS for a few years, I finally found out I was lactose intolerant. My doctor told me to get Lactaid. It was the best thing in my life. I take it sparingly (half a pill if I am not eating much, and not daily). I also take a mild course of Acidophilus on a daily basis. I just wanted to post this so that those who are struggling with it can possibly find help.

I have just recently been diagnosed with Irritable Bowel Syndrome. My doctor thinks I may have a sensitivity to milk, so I have been trying to avoid it, drink Lactaid Milk and I also bought some Lactaid Ultra pills... Well the first box I took (over a period of a few weeks), turned out fine. I'd eat ice cream, cheese and be okay. Most recently, last week I had wanted ice cream, so I took one and within a couple hours I had the worse feeling of car sickness, and then vomited. It was complete with chills and being hot at the same time. I also had had chili for dinner so thought it was that...wrong, today I took a lactaid pill and ate nothing that would normally trigger my IBS and about 2 hours after taking it I felt like I was car sick and vomited.

Thank you all guys - I didn't know we were so many... I come from Europe (here and especially in my country, we are not that concerned with lactose intolerance - we generally try to avoid diary food) so on my last trip to US-I bought these pills hoping I can finally eat diary... The first week I didn't feel anything, but after taking a pill every second day approximately (I try not to eat diary as often) everything changed - I started vomiting a lot as if I had food poisoning! Something that irritates me the most is that I started doubting that something is really wrong with my stomach and even went to a doctor, but after I vomited few times in a row after taking the pill, I finally stopped taking the pills! I am very content I found this forum - now it's crystal clear what was wrong with me all these days... Thank you all!

I'm so glad to read all these posts. I'm not crazy after all!!!!!
I have also had all the above symptoms. I have labeled myself a scientific experiment and this weekend I'm going to try to cut a Lactaid fast act in half and see if a lesser dose works with no side effects.
Thanks!!!

I've been thinking that stress was causing all these symptoms but now I'm thinking differently. I only took Lactase Enzyme because I thought herbal was better. After taking it for a week I found I could eat a variety of foods I wasn't able to eat prior.
One morning I awoke and was bleeding profusely from the bowels. The bleeding went on for four days then stopped. The doctor booked with with a specialist who said it would be two months before he could see me so I figured I'd cure myself or bleed to death.
I started drinking cabbage juice and am taking 3 acidophiles daily.and that stopped the bleeding completely. Last night I had a craving for ice cream which turned out to be a bad mistake. The pain was excruciating although I don't vomit and didn't get diarrhea. It looks like the side effects of this super duper lactose cure is permanent because I haven't taken the enzyme for a month now.

Thank you so very much! I know that if I googled "side effects" lactaid pills I would find the answers! This is worse than how I would have felt without taking the pill. I had a latte with 3 shots of espresso and within minutes I began experiencing nausea, headache with a very sour stomach, so I took Zantac. I feel like vomiting (but it won't come) and I will need to leave work early I feel so bad. I am done with that and wish I had not invested in a HUGE supply!

lactaid milk for a NON lactose intolerant person! eating regular dairy all day long, lots of normal cheese and ice cream daily... bought the lactaid for my cat..but ended up making COFFEE with it..latte style.. a full 8-10 ounces...
for a month now... and ended up with an ammonia smell to my urine and underarms..skin in general.. afraid of kidney problems as I also developed TERRY's NAILS..or "half and half nails" WHITE nails!!! the ammonia smell and the white nails indicate kidney troubles... my tests came back normal for kidney and liver... I attribute this to the lactaid so I hope this helps someone who may read this!!! these symptoms 100% coincide with the lactaid, NOTHING else is different in my diet..maybe my body got confused having lactase enzyme..AND normal dairy at same time.? maybe its not for people who are NOT lactose intolerant or for people who will ALSO include some regular dairy in their day... (without use of tablets) from what ive read here, you people are mistakenly believing you are intolerant... when all you need is probably PROBIOTICS after a course of antibiotics..which killed your healthy bacterias..and rendered you ineffective at digestion. That happened to me. takes months to re-establish the bacterias..and can even be a YEAR or two even, AFTER you took antibiotics that your digestion finally gave up..your antibiotic use didn't have to be "recent"
Thank you

I can't even stand up because of my very very painful stomach cramps which I just realized must be from Lactaid. I've been taking it almost daily (just once a day) about a month and I've had no issues until last week when I got violently ill after eating (and taking a pill first). I didn't really think anything of it until today....I haven't even been able to eat because of the pain and decided to google lactaid and see if maybe that was causing it and came across this site...I definitely won't be touching Lactaid again.

Thank you! I have been experiencing the same problems you all have posted! My doctor said it was probably stress from the holidays and my recent move and prescribed me ulcer medication. After 2 weeks I started to feel better, but not completely normal yet. For a while I went without coffee because I thought I developed an acid reflux problem along with the vomiting and stomach cramps and diarrhea, and I was taking prilosec as suggested by my pharmacist. Things seem to be getting better, so I bought Lactaid Milk and the last few weeks have been experiencing gas again. I was beginning to think it was my low fat low calorie diet with artificial sweeteners. I stay away from Splenda, because that really gives me gas problems, but sweet in low is okay. Tonight my husband and I went and got frozen yogurt, I took a Lactaid Ultra with it and about 30 minutes later I was cramping and on the toilet with diarrhea and vomiting. After reading this site, I realized Lactaid has got to be the problem. For now I am going to stay away from as much dairy and non dairy stuff I can and never use the Lactaid again. Hopefully things will get better and I can have small amounts of dairy from time to time. I am only 28 and I feel like I am having all kinds of digestive changes. Is this normal? Thank you again for your comments!

i introduced my bf to lactaid about a month ago since we discovered he was lactose intolerant. i really thought it would help considering he still loved to eat cheese and other lactose containing foods. at first, the lactaid seemed to be helping but just last week he took 3 extra strength lactaid pills because we were having chicken cordon bleu for dinner, he woke up 1 hour later with severe stomach pains and he was vomiting over and over. this lasted about 1.5-2hrs. i'm not lactose intolerant and didn't see the connection to the lactaid pills. we thought it was just from chicken cordon bleu because he had it before without the lactaid pills and he got sick from it too. today he took 2 extra strength lactaid pills and again, about an hour later he was feeling ill and was vomiting and experiencing diarrhea. we can now conclude it was the lactaid pills causing him all this pain. i feel so guilty for introducing him to these pills because i thought they would work. never again would i want to see him go through that much pain.

i gave my 12 year old son a Lactaid fast Act last night with his ice cream. He has recently been diagnosed as lactose intolerant. This was the first time I had given him any lactase. This morning he woke up vomiting and has been sick all day vomiting and having diarrhea. Terrible stomach pains, nausea, diarrhea, vomiting.

Well, i haven't been vomiting..although i have been feeling nauseous... i figured it was because of the lactaid pill that i've been taking but i stopped taking it a while ago and yet i still experiencing these side effects...i have the same side effects as pocoloco's minus the vomiting......Also i've been getting constant headaches that come and go. Distracting me from my schoolwork..i don't know what to do i guess i have to stop taking these pills..im getting a blood test this week and we'll see how that goes.

My story is very similar to the others here. I had taken Lactaid a few times without any problems. I did take two a little over a week ago with dinner and about an hour later I was violently vomiting. I had never been that sick before. It continued for a couple of hours, and I finally went to sleep with terrible pains all over. It took a few days to feel like myself again. I thought originally it must have been food poisoning from the restaurant. Then the other day I took two more with breakfast and the same thing only worse happened. I vomited so hard I thought my back would break. Bed rest for the rest of the day with chills and pain. Now its my third day out and I'm still feeling nauseated and weak. Pepto Bismol is not helping either. I just want to feel better again. I got rid of all the Lactaid in the house as two of my children take it also, but there is no way I'm taking a chance with them. I felt like I was going to die from poisoning or something, I can't imagine a child going through this.

I take a Lactaid tablet in the morning before I drink my coffee or tea with milk in it. I get a sore stomach and feel nausea for about an hour or so, then it goes away. I get progressively better during the day.

When I take a tablet with milk for dinner, it doesn't happen. I am wondering if it is the combination of the Lactaid pill and the coffee and the tea that is doing it. By the way, both are decaf!!

So I am going to cut out the Lactaid and tea and/or coffee in the morning and see what happens.

Three years ago, I came to the conclusion that I was lactose intolerant. I switched to soy milk in my lattes. A couple of months ago, I learned about lactaid and decided to go back to regular milk. The product worked great but then after about 3 weeks I began to develop stomach pain after my visits to the coffee shop. I didn't know what was causing it. Had I become sensitive to the acid in the coffee? Was it the artificial sweetener I was using to make my scones? Maybe I wasn't taking enough lactaid to counter-act the effects of the milk. After a few 'tests' I decided that I needed to take more lactaid. So this morning I took two pills with my latte and within 20 minutes I was in so much pain I had to call my husband to come drive me home. As soon as I was feeling better, I got online and googled 'side effects of lactaid' and found this site. I will never take lactaid again. It's back to soy lattes for me!

I, too, am lactose intolerant and have been taking Lactaid. Just three days ago, I had another attack of severe abdominal pain, constipation, then diarrhea, and the feeling that I needed to vomit. The severe pain lasted for two hours. I still have some discomfort. I nearly called 911. This episode is the third that I have had. I was hospitalized for four days last May. That time and the one previous to it, I was diagnosed with ischemic colitis. No firm explanation was given for the cause other than constipation could cause it. However, the first time that I experienced ischemic colitis, I was not constipated. I now suspect that Lactaid may have brought on all three episodes and will stop taking it. I would much rather have the side effects of milk then those of ischemic colitis!

I have a lactose intolerance and was told to try taking lactaid supplements. I tried taking it once months ago but experienced severe abdominal troubles---pains, gas, bloating, vomiting and diarrhea.
Thinking it might just have been a coincidence at the time, I tried taking a tablet just yesterday. Within hours, had the same syndrome. Vomiting, pain, diarrhea. Lasted about 4 hrs at worst, but several more hours of pain.

Would never even think of trying to do it again.

THIS AM FOR THE FIRST TIME IN ABOUT 2 WEEKS I JUST TOOK 2 LACTAID CHEWABLES AND NOW I AM EXPERIENCING UPPER ABDOMINAL PAIN AGAIN! MAYBE IT WASN'T THE HERNIA @ ALL???

I am so glad I found this site with Lactaid experiences. Thank you. Since starting lactose enzymes (Walgreen's generic) this past month, I've experienced severe constipation and severe acid in throat (LPR reflux). I will be cutting this enzyme from my diet and see what happens. Will post my results later ... very interesting.

If it turns out to be the Lactaid after all, I can certainly deal with the gas from time to time much easier than the severe reflux, for sure.

Brought a box of lactaid ultra last week. I took a few pills Thursday and Friday, I was o.k. Starting on Sunday, my stomach started hurting so bad, I had to be rushed to the ER. They did X-Rays & Cat Scans, nothing found except my liver enzymes were a little high. II am about to go get some Kaopectate and never use the ultra lactaid tablets again. My stomach is still in pain every morning.

Just had a bowl of cereal, took two lactaid chewables just before and about two spoonfuls into my cereal I was running to the bathroom with violent vomiting. I had been using lactaid for about a year and lately I had been feeling kinda nauseas when I used it but had not pinpointed to the reason. Until today I can now surely say it was the two lactaid tablets I took. The reaction was almost immediately and violent to say the least. Does any one know whats going on with this type of reaction after you have been taking it just fine for some months and then this reaction to the product?

My 2 1/2 year old has been on Lactaid milk now for over a year. Just after her 1st birthday she began this mysterious vomiting all the time.
She did test positive for the rotavirus right around her 1st birthday but the vomiting and loose stools continued for nearly a year afterwards. So after numerous tests including a horrible one to test how much reflux she had (which came out as minimal) her docs said she must be lactose intolerant. We put her on Lactaid but the vomiting continued. It did get better but it didn't totally go away until just after her 2nd birthday. Then more than 8 months later with no throw up she came down with what I think was the 24 hour flu because she couldn't keep anything down for a full day. Took her to the docs and they said just keep her on liquids as much as possible to keep her hydrated since she also hadn't had a wet diaper in more than 12 hours. The next day she was better and finally had a wet diaper but now she complains of a tummy ache all the time after she drinks her Lactaid. At first I thought maybe it's a comfort thing since I held her so much when she had the flu but now I'm not so sure. She has been complaining now for over two weeks. The only other thing that is new for her is we are trying to potty train. She has woken up with a dry diaper for over 6 month now so we thought she would be ready. However, she is very reluctant and holds her pee for a hours after she wakes up dry. I do notice that she also has quite a bit of gas when she is complaining of her tummy hurting and her stools are firmer than they used to be. I thought maybe it was because I would buy generic Lactaid like one person mentioned but she complains even with the good stuff and even the new Organic Lactaid. She doesn't eat much dairy products other than milk. She doesn't like yogurt and rarely eats cheese and we don't give her ice-cream. So not sure what is going on?? That's why I was searching on the net and found this site. Hope someone has some suggestions for us.

I am so glad I found your comments regarding Lactaid. Although I haven't experienced the vomiting most of you have mentioned, I have suffered the last few weeks or so with diarrhea and nausea. I found drinking water has kept the thoughts of vomiting at bay. However,I have gone to bed in the fetal position spoken about and slept. When I began Lactaid, I purchased the "best" brand. It was working very well. After the first bottle, I bought one of the generic brands. Now, I realize the mistake I have made. At first I thought they weren't mixing well with the "hotflash" medication I take, but after elimination testing, that isn't the case. Reading your blogs have just verified my pain and my need to either go back to the "best" brand, or stop taking Lactaid altogether. Thank you and have a painless day!

I, too, experienced the violent vomiting from taking a Lactase enzyme tablet (it was the store-brand generic version of Lactaid), after having taken it just fine for months.

My mom was visiting my husband and I and we all went to breakfast. I took a tablet right before I started drinking the large glass of milk I ordered (I'm weak when it comes to dairy, oddly enough). Within an hour I was home, vomiting, and dealing with abdominal pains and bloating. I continued to vomit for a couple of hours until finally, I was able to sleep.

A week later, I was eating with my husband at a restaurant for lunch, and because I had sour cream and cheese on my tacos, I took a tablet. About two hours later, I was calling him to take me home because I was sweating and it dawned on me what was going on. I felt exactly how I did the last time. By 8 that night, I was done vomiting.

I will be avoiding this product, generic or name-brand, for good now.

Recently, I had an experience very similar to pocoloco's experience with Lactaid. The main difference is that pocoloco experience seems to have wained within hours, mine were much more severe and lasted for days.

On a Monday, I took some Lactaid before eating a salad, that had perhaps 2 tablespoons of Ranch dressing. The next morning I awoke with very painful stomach pains. Like pocoloco, I feel I have a high threshold for pain, but throughout the day, I was unable to concentrate on my work because the pain was so severe. I went to my doctor the following day as I had not made a connection between my pains and Lactaid. The doctor had bloodwork done and a sonogram performed. She thought that my pain may have been the result od some gallbladder trouble or a viral infection. She prescribed a strong antibiotic, pain medicine and ulcer medicine to attack it from multiple angles as I am a healthy 32 yr old.

Over the next several days, I was feeling better, but still in discomfort. On that Friday, I took a Lactaid pill with a bowl of cereal for dinner around 7-8 pm. By 11 pm I was vomiting violently and had extreme abdominal pain. Again, because I had feeling better, I thought that perhaps I had a bad reaction to the combination of antibiotics and pain medicine. I vomited over a period of 4 hours, and like pocoloco, was expelling yellow/green liquid (bile?) near the end of the experience (3-4 am).

Between Saturday and Tuesday, I was still in discomfort, but was 90% better by Tuesday. I decided on Mexican food for dinner. I took a Lactaid pill and had some Queso with chips for an appetizer. By 11 pm, I was vomiting more violently than the first time and had a strong bitter taste associated. I finished vomiting around 5 am this time and the following day was still nauseated and in very strong discomfort from stomach pains. This was all it took to finally connect the dots and realize that the effects were the result of Lactaid, not a viral infection or stomach flu.

I would say my experience was very similar to pocoloco's, except that my stomach pains lasted over several days and my vomiting was over 4-5 hours as opposed to his 1-2 hour experiences.

About eight to ten years ago i had a violent reaction to lactaid. I had taken it numerous time before with no problems and then I woke up one morning - had a bowl of cereal and a lactaid pill - within the hour I was experiencing severe stomach pain along with vomiting and diarrhea. I thought it might have been due to the fact that i had had very little to eat the day before and only a bowl of cereal that morning with the extra strength pill.

the following weekend i was brave enough to try it again with some ice cream at night (this time i had a full stomach from dinner). BIG mistake - this time it was worse - the stomach pain was out of this world (i have a high pain threshold but this had me in the fetal position) and i couldnt leave the toilet and trash can for a few hours. My girlfriend was scared and called one of those nurse hot lines. they told her to coat my stomach with some kaopectate - which seemed to help. I checked the bottle of lactaid - and the expiration date had passed - so i threw it away and swore off of lactaid pills. fortunately they came out with the lactaid milk!

Fast forward to now - never touched the stuff again. well the other day I was out of lactaid milk and my wife (yes the same girlfriend) had picked up some samples of lactaid pills at a trade show - so I guess with the passage of time - I forgot how painful and miserable the other experiences had been - so i took the pill. Nothing happened!

Last night i decide to take another one because i had a craving for ice cream (had been awhile!). I figured it was ok since i had no reaction a week ago. Well sure enough - within the hour I was on the floor in severe stomach pain - followed by vomiting and diarrhea. This time we had kaopectate in the house - so i started taking it - well i just threw it right back up.

This episode lasted about an hour and a half this time. There was a metallic taste in my mouth about the third time i vomited, and the fifth and final time, there was puddle of yellow liquid that came out at the end.
