Rapid onset-fast acting insulin
Rapid onset-fast acting insulin always looks clear. It is fast acting and starts to work within one to 20 minutes. It peaks about one hour later and lasts from three to five hours. When you use this type of insulin, you must eat immediately after you inject.
The two rapid onset-fast acting insulin types currently available are:
1. NovoRapid (Insulin Aspart)
2. Humalog (Lispro).
Short acting insulin
Short acting insulins always look clear. They begin to lower blood glucose levels within half an hour, so you need to have your injection half an hour before eating.
Short acting insulin has a peak effect at two to four hours, and lasts for between six and eight hours. Short acting insulin types currently available include:
1. Actrapid
2. Humulin
3. Hypurin Neutral (bovine – highly purified beef insulin).
Intermediate acting insulin
Intermediate acting insulins always look cloudy. They have either protamine or zinc added to delay their action. These insulins begin to work about 90 minutes after you inject, peak at four to 12 hours, and last for 16 to 24...
