What is Dopamine
Dopamine is a type of medicine made from a substance found naturally in the human body. It helps improve the efficiency of pumping in the heart and increases the flow of blood to the kidneys. Dopamine injection (Intropin) is used to treat certain ailments that occur when you're experiencing shock. This can result from cardiac arrest, trauma, surgery, heart failure, kidney failure, and various other serious medical conditions. Dopamine can also be employed for other purposes that are not covered in this guideline for medication.
Inform your healthcare providers whether you have aortic calcification or circulation issues, diabetes, frostbite, Buerger's asthma, sulfite allergy, or the presence of blood clots in your history. Inform your physician about the prescription and over-the-counter medicines you take, particularly when you've used an MAO inhibitor such as furazolidone (Furoxone), isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam, Zelapar), or tranylcypromine (Parnate) within the past 21 days. In an emergency, it is not always possible to inform your healthcare providers about any health issues. Be sure that any physician caring for you in the future knows that you've received this medication.

Dopamine injections are administered by a doctor in a medical environment, so it is unlikely that you will not take the dose.
What happens if I overdose?

Details on dosage
Adult Dopamine Dose for Nonobstructive Oliguria:
Initial dose: 1–5 mg/kg/min in a continuously administered IV injection.
Titrate until you get the desired level of response. The administration of more than 50 mg per kilogram per minute is used without risk in severe situations.
Usual Adult Dose of Dopamine for Shock: Initial dose: 1–5 mg/kg/min with constant IV infusion
Titrate according to the desired level of response. Dosage rates of greater than 50 mg per kilogram per minute are used without risk in severe situations.
Usual Pediatric Dose for Nonobstructive Oliguria: less than one month less than 1 month: 1 to 20 mg/kg/min via continuous IV infusion, gradually increasing to achieve the desired level of response.
1 month and older 1 month or older: 1 to 20 mg/kg/min through continuous IV infusions, gradually increasing to achieve the desired level of response. Maximum of 50 mg/kg/min.
The effects of dopamine on hemodynamics are dependent on the dose.
Low dose 1 to 5 mcg/kg/minute Increased renal blood flow and output of urine
Intermediate dosage: 5 to 15 mg/kg/minute increases renal blood flow, heart rate, cardiac output, cardiac contractility, and blood pressure.
High dose: more than 15 mcg/kg/minute. Alpha-adrenergic effects begin to take over vasoconstriction and blood pressure.
Usual Pediatric Dose for Shock: less than one month via continuous IV infusion adjusted to the desired level of response.
1 month and older 1 month and older: 1 to 20 mcg/kg/min through continuous IV infusions, adjusted to the desired level of response. Maximum of 50 mg/kg/min.
Dopamine's hemodynamic effects depend on the dose.
Low dose 1 to 5 mg/kg/minute Increased renal blood flow and output of urine
Intermediate dosage 5 to 15 mcg/kg/minute, increasing renal blood flow as well as heart rate and cardiac contractility, the output of the heart, and blood pressure.
The highest dose is greater than 15 mg/kg/minute. Alpha-adrenergic effects start to dominate vasoconstriction and blood pressure.
