Pharmacy - viagra


Expert: Eric Brandt - 5/1/2009

Question
my husband found some old samples - dated 5/08, are these safe to take?  How long can you keep these and have them safe?

Answer
Hi Karen,
These pills are not going to be as effective as when they were within date. They do not break down to dangerous chemicals. At the expiry date the manufacturer does not guaranee potency greater than 90% of label claim. How fast they deteriorate beyond the expiry date is an unknown.
Thank you for using Allexperts
Sincrerely,
Eric Brandt, B.Sc. Pharm
