There are many health centres spread around the island and another one in Porto Santo. Some are equipped with emergency service facilities. Some of the private clinics have also emergency services but in case of an emergency most tourists will visit the Hospital 'Cruz de Carvalho'.
Medical insurance is strongly advised, even though EU citizens can obtain a refund of most medical costs by using the form E111 (available at health offices in your country).
There are many English-speaking doctors and dentists. Your hotel will always be able to recommend one.
The local chemists (farmácia), recognisable by a green cross sign, will have just about anything you may require and there is always one open after hours in each area. The location of the duty chemist is displayed on every chemists entrance door.
