I read one page that said 15% of people get nausea with Lexapro. I know that doesn't "help" but it's the #1 side effect so maybe a little calming to know you're not alone?

Too, another site said, "Patients taking LEXAPRO typically have mild to moderate side effects which tend to go away with continued treatment."

As to what to do: "Often, simple changes to your diet can help you to significantly reduce your symptoms of nausea. If you are feeling nauseated or have been vomiting, it is important to keep as hydrated as possible. If you lose too much liquid your body can lose important electrolytes that it needs to function. Drink only clear liquids for the first 12 hours after vomiting. Avoid caffeinated beverages and all dairy products.

"Certain foods that help nausea are also a good thing to try. Eating starchy foods, like crackers, helps to absorb excess stomach acids. Sucking on crystallized ginger can also help to reduce nausea. Avoid citrus fruits, juices, and other acidic foods, as this will increase your nausea. Gradually introduce solid foods after 12 hours, beginning with applesauce and working your way up to breads, cereals, and eventually, protein products."

Don't know about how well any of those will help. I'd ask your doctor, maybe your dose isn't right?
