The Portugal Health Declaration Form is an easy document to be filled out and sent to various pharmacies, physicians and hospitals in Portugal so as to receive a health prescription for specific medical treatments. The majority of the time, one fills out the statement form only once at the time of getting a health diagnosis that's when the doctors give you a wellness prescription. If however, you need to complete the declaration form more than once, then it is recommended that you take action every time you receive a medical diagnosis. This would save you the trouble and cost incurred for repeating the exact same procedure.
