Is it possible to break the dose of Trulicity 1.5 mg into two smaller ones, i.e. 0.75 mg?

Trulicity is available in semi-automatic pens. They only allow you to give a specific dose of the medicine - such as is written on the packaging and pen. To the best of my knowledge, there is no way to give half the dose of 1.5 mg, or 0.75 mg, with a 1.5 mg pen - that is, it is not possible to use one pen twice. If you have to use a dose of 0.75 mg, the only way out is to buy it at the patient's request in a pharmacy with a prescription for a drug with a dose of 0.75 mg or with a higher dose. According to the current rules of prescription, the pharmacist can dispense the drug written on the prescription in a smaller dose (2 pens of 0.75 mg instead of 1.5 mg), i.e. he can dispense the drug at a dose of 0.75 mg if a pen at a dose of 1.5 mg is written on the prescription. Of course, these are general rules, the decision is made by the pharmacist dispensing the drug. If the prescription has already been fulfilled, then the drug is not subject to exchange and it remains to visit the doctor to obtain a prescription for the correct dose of the drug.

How about injecting the dose into an insulin syringe. Inject the half dose then refrigerate the other half for the next week.
