MX
- oral/buccal/IV prochlorperazine
Wax obstruction
Management?
1st: give olive oil drops/almond oil/ Nacl drops/ sodium bicarbonate 5% drops for 3-5 days.
2nd: Irrigation
If unsuccessful > continue drops for 3-5 days more then try irrigation again.
Instill water, wait 15 mins and then irrigate.
refer to ENT.
Some patients go to private clinics for micro suction (much safer than irrigation)
