Insulin pens
These are available just like any oversized ink pen that can be carried in the pocket. They are available in two forms – temporary and permanent pens.
Temporary Pens: These are made of plastic with the insulin already filled in. However the pen needles have to be fitted separately. The pen has a colour-coded knob representing a particular type of insulin or a combination, e.g. yellow represents ‘short acting’ insulin. The pen has units marked on it denoting a particular dose level. The pen has to be adjusted to the recommended dose, and is then injected at the injection site. Once all the insulin is used up, the pen is to be discarded.
Permanent Pens: These are made of metal and are slightly heavier. The cartridges filled with insulin are separately available. The pen has to be fitted with these cartridges and used in the same manner as the temporary pen. Once a cartridge is fully used, new cartridges are fitted and the pen can be reused.
