Does Accutane contraindicate topical antibiotics or steroids (specifically, ear drops for otitis externa)?
There is no contraindication for the use of topical antibiotics or steroids with Accutane. They may be used as necessary according to the advice of the prescribing physician.
Why aren't there olive oil drops on the shelf for the ears?
People have been using ordinary olive oil as eardrops for ages, and it is not considered to be a drug, so cheap.
Packaging and selling it as a drug would involve too much costs to have it researched first, then registered, packaged, with a not to use after date, a lot of bureaucracy, all costing a lot of money, etc. etc. making the olive oil ear drops on the shelf unbearably expensive.
