You will be fine with that close of an exp date. You have to remember with most pharmaceutical products the exp date carries a buffer. This is to ensure product quality. Just like most food products.
Most commonly on pharmaceutical products is 30/60 days for over the counter. Of course the the product will deteriorate over time as the ingredients begin to break down over time and dissolve.
So to answer you question. Yes you can use it as its a resent exp date. Will it be as affective as when you first bought it, probably not 100% but close enough to be effective with in the expiration date window.
