Lactaid and abdominal pains

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.
