Dr Boling's Clinical Pearls: Prescribing Drugs for the Elderly

Consider adverse drug reactions with any new symptom, especially if it's nonspecific; remember dry mouth, constipation, urinary retention, sedation—we all know these but keep forgetting them.
Learn the pharmacology specific to geriatric patients.
Lower the dose of most drugs you prescribe.
Adjust the dose for potential clearance, liver, and hepatic problems.
Check for drug interactions using your palm pilot.
Get to know pharmacists; they are useful resources.
Teach your patients; remember, "doctor" means "teacher" in the original Latin.
Become familiar with updated medication lists.
Prescribe medications according to indications, not off-label.
Limit use of anticholinergic drugs.
Use generic drugs when you can.
Your patients are your best source for their own preferences; take time to ask about their preferences.
