Tirzepatide, a novel GLP-1 receptor agonist and GIP receptor agonist, is not currently available in compounded formulations. This means that a pharmacist cannot mix or prepare different strengths of tirzepatide. The dosages available are only those approved and manufactured by the pharmaceutical company, Eli Lilly and Company. Therefore, there's no such thing as a "compounded tirzepatide dosage in units." Any attempt to obtain a compounded version should be approached with extreme caution due to potential safety risks and the lack of quality control.
However, the question of "units" often arises because patients are familiar with insulin dosing in units. It's crucial to understand that tirzepatide is measured in milligrams (mg), not units. While both are used to measure medications, they are distinct units of measurement referring to different properties of the drugs. Insulin's potency varies across types and manufacturers, making units a relevant measure of activity. Tirzepatide, however, has a consistent potency, therefore mg is the appropriate and only clinically relevant unit of measurement.
What are the Available Dosages of Tirzepatide?
Eli Lilly and Company offers tirzepatide under the brand name Mounjaro in several pre-determined dosages:
- 2.5 mg
- 5 mg
- 7.5 mg
- 10 mg
- 15 mg
These dosages are administered via subcutaneous injection once weekly. Your doctor will determine the appropriate starting dosage and titration schedule based on your individual needs and response to the medication.
Why is Compounding Tirzepatide Risky?
Attempting to compound tirzepatide carries significant risks:
- Lack of Quality Control: Compounded medications aren't subject to the same rigorous manufacturing and quality control standards as FDA-approved medications. This increases the risk of inconsistencies in potency, purity, and sterility.
- Incorrect Dosage: Improper compounding could lead to inaccurate dosages, potentially resulting in under- or over-treatment. This can affect treatment efficacy and safety.
- Potential Contamination: Compounding processes, if not conducted under sterile conditions, can introduce contaminants that lead to infections or other adverse reactions.
- Legal and Ethical Concerns: Compounded medications are not regulated in the same manner as FDA-approved drugs. Using a compounded version may violate legal guidelines and may not be covered by insurance.
How is Tirzepatide Dosage Determined?
Your doctor will carefully consider several factors when determining your tirzepatide dosage:
- Your medical history: This includes existing conditions, previous treatments, and potential drug interactions.
- Your weight and BMI: Dosage adjustments may be made based on body weight.
- Your response to the medication: Your doctor will monitor your blood sugar levels and overall health to optimize your dosage. They may increase the dosage gradually as needed.
- Potential Side Effects: Side effects, such as nausea and diarrhea, may influence dosage adjustments.
What if I have Questions About My Tirzepatide Dosage?
Always discuss your treatment plan, including dosage and potential side effects, with your doctor or a qualified healthcare professional. They can answer your questions and address any concerns you may have regarding your specific situation. Do not attempt to adjust your dosage or obtain compounded tirzepatide without their explicit guidance.
