Chinese Restaurant Syndrome

Alternate Names : CRS, MSG Allergy, MSG Symptom Complex

What are the treatments for the disease?

With symptoms so similar to an allergic reaction, treatment is sometimes given before the diagnosis is made. Antihistamines are the most frequently used medication. However, if CRS is diagnosed, the symptoms will usually go away without treatment within 2 to 3 hours.

What are the side effects of the treatments?

Some antihistamines cause drowsiness.

What happens after treatment for the disease?

After the symptoms resolve, a person with CRS often feels weak and tired for a day or two. Afterward, their activity level and appetite return to normal.

How is the disease monitored?

Avoid foods containing high levels of MSG. However, MSG is in many foods other than Chinese foods, and it would be difficult to avoid it completely. Because the symptoms are related to the amount of MSG ingested, very mild symptoms are often more of a nuisance than an illness. A person should read food labels and order Chinese food prepared without MSG.
