Polypharmacy is defined as "the use of multiple drugs administered to the same patient, most commonly seen in elderly patients. It includes also the administration of excessive medication."[1] Polypharmacy hinders patient compliance with medications and may increase drug-related side effects and adverse reactionss[2].
Taking 4 or more prescriptions daily is more common among low income patients according to one survey.[3] This occurs in 32% of patients with household income below $25,000; whereas this occurs in 12% of those with household income above $75,000.
Using 11 or more chronic medications is a risk factor for drug toxicity.[4]
Combining multiple medications into a single 'polypill' may help patients.[5]
However, taking "three drugs at half standard dose in combination" may be better than one drug at standard dose according to a systematic review.[6]
Reducing polypharmacy
Matching patients' medical problems and their medicines may identify unneeded or low priority drugs that can be discontinued.[7]
Delaying antibiotics for 48 hours while waiting on improvement of respiratory tract infections[8][9] or cystitis[10] may reduce antibiotic usage and reconsultation; however, this strategy may reduce patient satisfaction.
