Shortly: If it's your first time in Spain, once you have the 'tarjeta sanitaria' (health card), just ask for a meeting with your doctor and present him your major problems and medications.

In more details (Note: this is for the public health system):

1. You need an 'empadronamiento', which means to register to the local authority (usually town hall), with an official paper regarding your location (rental contract for instance). Could take some times (like up to 2 months).
2. Once you have it, you can ask for the health card. Again, could take some times (2 to 4 weeks).

So it's better to have no problems and enough medications in the meanwhile. There is an european health card but if you are in UK, I'n not sure you can get it.

On the 1st meeting, the doctor might recommend some exams but eventually, you will end with an electronic prescription. For instance, you have blood pressure, the doctor recommends pills for that, you go to a pharmacy and present your health card, and you get your pills. Usually once a month, and you have to renew the electronic prescription regularly - like every 3 months. You can do that by phone.

Your medications might be different in Spain so presenting the english ones might not help the doctor, go with the notice.

Hope it helps.

Good question. I would also like to know whether it is common to bring translated medical records from Germany when registering with a doctor in Spain.
