Subcutaneous injection problem!

Hi, I know this is weird.
Nplate must be delivered through a subcutaneous injection, right?
I inject my self. This time, unlike any other time before, after I was drawing out the needle from my skin (after I had injected the required amount) It started bleeding a bit. It was very little tbh and ceased very quickly (within a minute). But the problem is that, is it possible that some amount of drug might have come out with the blood?! So I might possibly be underdosed and face the complications?
By the way, after I checked the injection site, it was swollen as usual (due to the fact that there's the solution under it) so visually, it was as swollen as previous times. But I'm still worried. Has anyone had ever had the same issue? I inject my belly all the time.
I usually keep the syringe for a week. I know that in the condition I hold the reconstituted drug, It will lose efficiency within 24 hrs. I have never used this remnant. But the question is: Should I be worried? Should I use the remnant within next 24 hours because I might have been underdosed?
Thanks!

Yes, subq.

Don't worry about the bleeding or if you see some of the medication come out of the injection site. You will be okay. Both have happened to me multiple times. However, I don't think your injection site should be swollen. Is that okay with your hemo?

Please don't keep your syringes. After use put them in a medical waste container. Do not ever re-use.

OMG - do not reuse a syringe!! Why are you doing that??
We had to give our cat sub-Q fluid and there is no way I would have reused a syringe on her!!

Thanks. About the swelling, I think it's the drug. In fact, I inject 0.7 ml and I think it's quite natural for it to accumulate under the skin. It vanishes within an hour or two. I think it gets absorbed? I also sanitize the injection site and try to follow all guidelines. But next time I visited my doctor I'll ask him.

MeIA!!
I said I have never reused a syringe. The fact that I keep the drug is that I'm afraid that at day 1 of injection, I might show symptoms and I think then I'd shoot my self again. But it's only a hypothetical scenario!!
It is written in Nplate leaflet:
"Storage of Reconstituted Solution
Reconstituted product with Sterile Water for Injection, USP that has not been further diluted can remain in the
original vial at room temperature 25°C (77°F) or be refrigerated at 2°C to 8°C (36°F to 46°F) for up to 24 hours
following reconstitution. Reconstituted product with Sterile Water for Injection, USP may be held in a syringe at
room temperature 25°C (77°F) for a maximum of 4 hours following reconstitution. Protect the product from light. Do
not shake."
About discarding, I don't have any special waster container. I simply throw it to the garbage can.

That is outrageously poor practice. You should have been supplied with a sharps container.
Needles should never be discarded in the trash can.

Yes, you are right. I know the risks.
I'll try to keep the syringes with my self and don't throw it out unless I find a safe way.

Sorry but from what you said it sounded to me that you reuse the syringe - I beg your pardon.
However a sharps container isn't expensive and one will hold gobs of used syringes!!

Lman, the pharmacy that gives you nplate should also ask you about supplies you may need. You should be able to ask them for sterile water, syringes, alcohol pads and a sharps container. They should all be free.

Use the alcohol pads on the sterile water and nplate vial before you inject the syringe into either. Continue using the alcohol on the injection site as well. After you inject the nplate, cover the syringe and drop it in the sharps container. When the sharps container is full you can empty or drop it off at the pharmacy or if you go for labs, they usually take will take as well.

Don't worry about missing out on a drop or two of nplate. You are doing okay.
