When you first start using Saxenda, 1 3ml pre-filled pen will last for 17 days or a pack of 5 pens will last for your first 46 days of treatment.
This is assuming you stick to the recommended increasing dose schedule, see more details below.
In short, how long a Saxenda pen lasts depends on how far you are into your treatment.
When you start using Saxenda, you must slowly increase your daily dose by 0.6mg every 7 days. This is to allow your body to get used to the treatment and reduce the likelihood and severity of side effects.
On this increasing schedule, 1 pen will last 17 days, 2 pens 28 days, 3 pens 34 days, 4 pens 40 days and 5 pens will last for the first 46 days of treatment.
Occasionally there may be side effects that take a little longer to improve. If you move up to the next dose and find the side effects intolerable then you can reduce back down to the previous dose for a further week before trying again.
Once you have reached 3.0mg daily you should remain on this dose.
At 3.0mg daily, 1 pen will last 6 days, 3 pens will last 18 days and 5 pens will last for 30 days of treatment.
