Q. How do they make Flu shots in advance for next season? They says every year Flu viruses are different so we need different updated Flu shots too, But that always makes me wonder how do they make Flu shots in well advance before actual Flu season starts and it's able to prevent people from getting Flu? Anyone know?

A. Good question ? , every year or so the influenza virus take a “drift”. That means he is changed a bit. So they go to the other side of the planet (where it’s winter when we have summer) and take 30 most common influenza viruses and make vaccines.

Q. Regarding Seasonal Nasal allergy. My father is suffering from seasonal nasal allergies. He took a 24-hour loratadine pill, 5 hours ago. His nose is still running just like it was. Can I take a benedryl, or is it dangerous to mix loratadine and benedryl? What else can I do to stop my nose?

A. except well known drug interactions- most Dr. check it out with a computer program they have. you need to ask a Dr. or a pharmacist about it. but i can tell you that if you wait 4 times the T1/2 - that is enough to consider the drug out of the system.
