Please do not go to your medical/health centre/hospital unless you absolutely have to.
If you are able, please sign up for the app Salud Responde. This app will allow you to request a telephone appointment with your GP. You can also request repeat prescriptions. Many regions have already said that if you have a continual prescription, it will automatically be renewed for 6 months. Many town have published a “banda” detailing who to contact, when and how as well as their procedures for blood tests etc
You can also call Salud Responde on 955 54 50 60
There is also a Coronavirus pre-diagnosis triage section on the app.
