Guaifenesin treats congestion, cold, flu, bronchitis, sinus infections, and may increase chances of pregnancy (obviously not the case for males).
Guaifenesin, available in many OTC cough syrups (tussin) is also available in tablets (mucinex) or available in generic form from many online pharmacies or health-food stores. The suggested dose is 400 - 1200 mg no more than twice daily. Guaifenesin is an expectorant -- so, take it with PLENTY of water. It thins the mucous membranes in the body -- NOT just the lungs or throat, but the ENTIRE (ENTIRE) body. you'll probably cough a bit more than usual for the first couple days -- that's GOOD -- you're getting rid of all the extra CRAP that shouldn't be there, in the first place. I have Asthma and Allergies (as well as a chronic sinus infection) I take loratadine, advair, singulair, benadryl, and albuterol. They work -- a little -- all together . . . but if I miss my guaifenesin -- I can definitely tell. It's rumored that it's also a useful remedy for CFS. Be careful, though -- guaifenesin can cause an increase in blood pressure -- so take it with PLENTY ( I cannot stress that enough ) PLENTY!!! of water!
