Oh no.... checked this guaifenesin and warns against my use as I have narrow angle Glaucoma and it can raise eye pressure... BUT doesn't say if "could happen" by putting in ears? This has been a problem for me since diagnosis of narrow angle Glaucoma, dant use this, cant use that...especially steroids, some anti-depressants and seems now this! ugh It seems its a chance to take many of the meds they list as problematic but it has meant I cannot take many helpful drugs for many issues in case affect my vision...J.
