The swine flu vaccine isn't the only medicine in short supply.

Tamiflu, used to treat swine and seasonal flu, is on the short list as well. Specifically there seems to be a shortage of liquid Tamiflu the kid-friendly version.

It's prescribed to children who have trouble swallowing pills, and the shortage is causing a big problem for pediatricians and parents.

The last 234-thousand doses of liquid Tamiflu were released from the government stockpile last week.

"You are probably going to end up running out and having greater shortages as the weeks go on as we continue to see the flu, especially the h1n1 which is what we mostly see right now," said Muriel Desimone, a pediatrician in Las Vegas.

There are no current plans by the government to intervene with the shortage.

Instead, they're urging pharmacists to use "compounding" which is a process to convert adult doses of Tamiflu into the liquid form for children.
