[|Human|] Please describe the process of using a hypodermic needle to inject liquid methotrexate. I have done it once with instruction but I need a reminder on all the steps for preparing the needle for putting in the little bottle of methotrexate. Plus I need a shot of 8mg and the medication is 1 litre? I can get two full shots from the bottle. Can I do a 4mg with one bottle and move to a second bottle for the second 4mg and still maintain the sterile injection? Or do I have to do 2 shots of 4mg with separate needles?
[|AI|]  If you need just 8 mg Methotrexate shot, it is recommended that you get yourself vials of Methotrexate with lower amount (weight in MGS) e.g. 15 mg. However, if you are having one with is 1 liter it would help to see the strength in terms of mg/liter. You have to be careful that you calculate and take the exact strength. While it is always recommended that you get the shot from a trained medical personnel to avoid any mistake, you can try to take it yourself under SUPERVISION. You need to ensure sterility and hence it is NOT recommended that you use the same syringe to take medicine from two separate vials.
