Pharmacies in Portugal have reacted to the demand from the public for the two anti-viral treatments against swine flu by ordering more from manufacturers GlaxoSmithKline and Roche.
Relenza and Tamiflu have been identified as being effective against swine flu, which has led to the deaths of more than 100 people in Mexico, with many more people being infected around the world following a visit to the Latin American country.
According to Portuguese newspaper Correio da Manhã, people are showing reluctance to eating pork because of fears of the disease.
However, no evidence has been found to suggest that swine flu can be transmitted through eating meat from infected animals as long as it is cooked properly.
Swine flu symptoms are similar to those produced by ordinary seasonal flu; fever, cough, sore throat, body aches, chills and fatigue.
People who have flu symptoms and recently visited affected areas of Mexico are encouraged to seek medical advice as soon as possible.
No cases of swine flu had been reported in Portugal at the time the Algarve Resident went to press.
