air bubble

why there is an air bubble in almost all pre filled syringes and pegasys also , is this to be expelled or to maintain the full dose it should be kept?

Yes since you aren't injecting the peg into a vein it really is no worry at all.  Just take the shot like you are supposed to and you are fine. I remember when they started me off on the redipens (hate them!) ...and every time a little tiny drop of meds would be on my leg afterward the injection no matter what I did and I would freak out SO bad thinking I wasn't getting all the meds......obsessive behavior of course it wasn't enough to do anything and I've been  SVR for three years.

there is no need to worry about an airr bubble- air bubbles are only of concern when injecting something into a vein!
better just to concentrate on where you inject and how you inject to avoid any unnecessary blemishes

By leaving the bubble and tapping it up to the pluger end - you are effectively giving a larger than prescribed dose. It would be irresponsible for me to reccommend this practice. Would't be prudent... not at this juncture.

Each syringe is slightly overfilled to compensate for this issue.  I asked this question also and spoke to a technician at Roche.  I am so sorry but I cannot recall exactly how much more is in the syringe but it is certainly enough to ensure you get the correct dosage.  For safety purposes it is best to get rid of the air bubble as instructed, however as you inject subcutaneously and not directly into a vein the air bubble is not likely to cause you a problem.

Don’t take the air out, you will lose some Peg.Inteferon.
The bubble are there because when you turn the needle down, the bubble goes to the top, and when you inj. you get all of the pegasys in your body without spoiling any of the drugs. An air bubble is not dangerous, but most of the air will be in the syringe, and you can also see when all of the drugs are out of the syringe.

I held up the syringe vertically, tapped gently so it became 'one air bubble' when it was a few bubbles, and pushed the air out until a drop of liquid was at the end of the needle.

It did seem to make it hard to measure exactly what dose I was taking once I got rid of the air.  I'm sure I lost a little on two shots when I got muddled up.  However, the nurse told me they were all premeasured.  

I'm sure the air bubble is there so that no pegasys gets lost in transit i.e. when we're preparing.   Just squeeze the bubble out gently before the shot.
