Most medicines are "over the counter" here.
If you go to the pharmacy with your existing (UK) tablets etc. with the prescription label on (with your name etc.), the pharmacist will look up the prescription and sell you/order for you the Spanish equivalent.
This has worked well for my wife, but she uses commonly prescribed drugs. If you need something unusual/risky etc., the process might be different.
We have private health insurance in Spain, but didn't bother the doctor until something new came up. When we eventually went to the doctor, she asked us what meds were were on and why. She also asked the usual questions ... what issues do you have/what surgery have you had etc. that was it.
