As an addition, in The Netherlands, family doctors have something called "phone-appointments". Half an hour at lunch time, they are on the phone, so you can call them for things you don't need to make an appointment for. Questions you have, what the best over the counter medication is for your kids cold, that kind of thing, the minimal things. If he thinks he can't do it over the phone, he will tell you to come in to see him.
You can also ask for a refill of your prescription, which will be sent to the pharmacy, and you can pick it up the next day. And yes, they will figure out whether you can still use it safely.
