Hi Frig,
Welcome to Healthcare Magic!
You can take these medicines but if you are a bit hypertensive also then you should measure the BP regularly because Nafarin can cause a shooting up in BP.
Augmentin is of the same group as Sumapen and is more potent antibiotic so you can avoid sumapen till you are on Augmentin.
Also sleep in a posture with the blocked ear up.
I hope the advise would be helpful for you.
