Q: needle size for methotrexate injection

I have rheumatoid arthritis, and am needle phobic (yuk-yuk, wrong disease to have!).


I wonder if I can use 30 gauge "diabetic" needles to inject methotrexate weekly... or if there is a difference between the viscosity of insulin and methotrexate that prevents me from using the 30 gauge insulin needle for this purpose.

I am currently using BD 1ml 27G 1/2 latex free syringe to inject 25mg/1.0ml/100U methotrexate.

Hi, I have been using 27 and 30 gauge needles for my methotrexate injection without difficulty re the viscosity of the solution.  Speak with your pharmacist and I am sure they will advise you on this issue.

Thanks for your imput. I have checked with the pharmacist, and there seems to be some confusion regarding this. My doctor said to check with the pharmacist, and the pharmacist said to check with the doctor.

Do you find that 30 gauge is...less frightening? I know it's not easy for a non-needle-phobe to answer!
