Patient/caregiver was educated on contraindications for using Guaifenesin as follows:
- Do not take Guaifenesin, if you ever manifested any allergic response to intake of Guaifenesin. Discuss your history of allergic response to this medication with your physician, without fail.
- In the event of any current manifestations of any allergic response with this medication, report it to your physician or other health care personnel immediately, to check regarding your safety with continuing on intake of this medication.
- Guaifenesin is extensively metabolized in the kidneys, to inactive metabolites that are excreted in the urine. If renal function is deficient, the metabolism of Guaifenesin can be compromised. This can lead to increased blood levels of the medication for longer periods of time, resulting in increased risk for side-effects with Guaifenesin. So, Guaifenesin must be used cautiously in individuals with history of compromised renal function, with close watch maintained for development of any severe headache, dizziness, drowsiness, and episodes of confusion.
