Q

Diphenhydramine Education-

A

breastfeeding moms can pass through breast milk, fetus can be susceptible to the side effects. Children are more sensitive to Benadryl which causes paradoxical effect (extreme opposite effect). Older adults watch for sensitivity bc hard time excreting- desired effects can be prolonged and cns depressive effect worred about become too sedated. Complaining about dry mouth- use ice chips, sugar free gum, and candy to increase saliva production

67
Q

Nasal Decongestants Education-

A

if MAOI taken= increased risk of HTN. Proper use of nasal med- do not use more than 7 days. Going past that there can be rebound effect. Antibiotic use proper- if drainage is still clear does not need it. Read the label of medications esp. when at pharmacy getting their own. Cold meds have more than one ingredient- acetaminophen or NSAID do not double up on meds. Take single ingredient medications to dry secretions (antihistamine). Increase fluid intake esp. with expectorant to thin mucous. Sit up right and deep breathing coughing for secretion excretion
