Byetta is increasingly popular among the prescribers ever since it is listed under PBS.
It is important to know how to use the Byetta pen.
The differences between byetta and normal insulin
1. Byetta must be kept in the fridge after each use. Insulin pen can be kept at room temperature for 28 days.
2. Byetta pen comes with a fixed dose/instruction. It is available in 5mcg or 10 mcg, to be injected twice daily within 1 hour before breakfast and dinner. Insulin dose varies according to individual's need.
3. Byetta MUST NOT be injected after a meal.
4. Byetta can be injected around abdominal area, arm and thigh. In the case of insulin, arm and thigh are less commonly used as site of injection.
SLOWS GASTRIC EMPTYING!!
Byetta slows gastric emptying and therefore potential interact with oral administrated drug.
1. oral medications that require rapid gastrointestinal absorption or medications associated with local gastrointestinal irritation, e.g. bisphosphonates or tetracyclines.
2. Gastroresistant formulations containing substances sensitive to degradation in the stomach, e.g. proton pump inhibitors, should be taken at least one hour before or more than four hours after exenatide injection.
3. For oral medications that are particularly dependent on threshold concentrations for efficacy, e.g. contraceptives and antibiotics, patients should be advised to take those medicines at least one hour before exenatide injection.
