Geri-Finals - Poly Pharmacy Flashcards
Prevent Toxicity
For Geriatric, initially Give 1/2 of normal adult dose because they are prone to adverse side effects.
Teach Med administration
Teach geriatric patient hoe to administer their meds, and make sure you receive a return explanation or demonstration so you know they understood you.
** A lot of times, elderly take their meds wrong; educating them will make it correct.
Medication reconciliation
- to check drug-drug interaction and drug-food interaction
- Ex. Vit K interacts with coumadin, so patient is not taking vit. K. But, patient eats food rich in Vit K such as green leafy vegetables. == It means that those food if they are not eating it regularly will interact also with Coumadin.
- Gingkgo Biloba, garlic, St John’s worth also interacts wth Coumadin.
- Tell patient to bring the brown bag and not just “give me the list” (bec they might not list everything esp the OTC meds.
- Aloe Vera is also a blood thinner – so do not take too much.
- Teach also the side effects and possible adverse effects of the drugs they are on and when they need to call the PCP is the adverse effects occur.
Monetary Matter and Pharmacy
- Assess if the patient are able to afford or have the resource to get/buy the meds prescribed to them.
- You may refer the patient to the social worker to make sure that patient gets the therapy he/she needs.
Toxicity in the elderly
