Your individual dosage of Azasan will be calculated based on factors like your weight, other medications you are taking, and the reason you are taking this drug. Azasan comes as a tablet and is taken either once or twice a day. If you have poor kidney function, you may need a lower dosage of this medication or may need to switch to a different medicine.
An Introduction to Your Dosage of AzasanThe dose of Azasan® (azathioprine) your healthcare provider recommends will vary, depending on a number of factors, including:
- The medical condition being treated
- Your weight
- How your body responds to Azasan (some people do not clear the drug from the body as well as others)
- Other medications you are taking
- Other medical conditions you may have.
As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so. People with poor kidney function may need lower Azasan dosages. Also, a test can be done to see if you have low levels of thiopurine S-methyltransferase (TPMT), an enzyme that helps clear the drug from the body. If you have low TPMT levels, you will need a lower amount (or a different medication altogether) to prevent serious side effects.
