Depends on age: No. The usual dose is 600 mg of guaifenisn and sometimes up to 1200 as a sustained release formula for an adult.. Anyone can be sensitive to any medication so it may cause side effects in a sensitive individual. Rashes, hives, trouble breathing are all signs of an allergic reaction. www.drugs.com has great information on any drug.

Guaifenesin: Guaifenesin is an expectorant. It helps loosen congestion in your chest and throat, making it easier to cough out through your mouth. Its effects maybe more theoretical than practical. Drinking adequate fluids will produce the same effect. I hate to leave the decision for you to make for yourself but , honestly, i would rather have you push more fluids.
