I use Mucinex LA 600 mg twice a day - it is guaifenesin extended release. I use the plain version without decongestants or anything else added. If you look in the stores, it is quite expensive, so I order mine on-line, often from e-Bay (where it comes in the factory-sealed boxes, often for 1/4 the price of the drug store) Most of the generic brands are not time-release, so don't be fooled by the lower price - you have to take it 4 times a day, and the action is not the same.

It effectively thins all the secretions - nose, ears, lungs... I have used it for over 30 years without any bad effects. My husband uses it too. I use the singulair and during bad allergy season a non-steroid saline spray. Years ago I was cautioned that incorrect use of nasal lavage can force germs deeper into my sinuses, so I don't use it - don't really need it with the Mucinex keeping things moving.
