It is important to differentiate between "khamr" and "alcohol".
The substance called "alcohol" is of three types:
1) That which is deadly, if you consume it you will die or become seriously ill. This is considered "summ" (poison) and it is permissible to buy, sell, transport, or use it, but not consume it. (You can use it in mouthwash, perfume, bug spray, etc, but not in foods or drinks)
2) That which intoxicates when consumed, a little of it or a lot, then it considered khamr (intoxicant), and it is not permissible to buy, sell, transport, use, or consume. The fataawaa mentioned above all refer to this category: khamr.
3) That which does not intoxicate no matter how much of it is consumed, then it is not a khamr, and it is halaal, like the small amounts of alcohol found in many foods and drinks that we eat every day. This type is permissible to buy, sell, transport, use, and consume.
So if the type of alcohol used in your medicine is type #3, then you may use it. If it is #1 or #2, then no.
And Allaah knows best.
