Hello,
Thank you for choosing DoctorSpring.
Since you have not mentioned the Indication, I am assuming that the Oxytocin was self administered without medical guidance. Oxytocin is generally administered as an infusion (slow dosages, not a rapid injection).
I would say it was not a smart move from your side. Luckily this is rather a safe medication. So unless the symptoms are persisting you should be okay. Cytotoxic can lead on to arrhythmias and blood pressure changes. So if you still have symptoms and/or if there is feeling like irregular beat, skipped heart beats, syncope, weakness or any unusual symptoms you should get medical help urgently
Hope this helps
Feel free to ask followups.
Thank you
