It is also important to disclose whether you have been prescribed any medication in the past 21 days especially MAO inhibitor like phenelzine, Selegiline, furazolidone or tranylcrypromine, rasagiline, isocarboxazid.
In case it is an emergency and there is no time to explain all of the above mentioned, it is good to let your doctor know afterwards. If a woman is pregnant or breast feeding she should tell the doctor about it immediately.

- Any history of blood clot
- Sulfite allergy.
It is also relevant to say whether you have ever used MAO inhibitor in the last 21 days like tranylcypromine (Parnate), salegiline (Zelapar, Emsam, Elderpryl), Phenelzine (Nardil) Isocarboxazid (Marplan) or Furazolidone (furoxone).
How is Dopamine Given?

What is the Recommended Dosage for Dopamine?
Normal Adult Dosage of Dopamine for Non-Obstructive Oliguria:
Usual dosage of dopamine: 1-5mcg/kilogram per minute using IV infusion continuously.
A doctor may titrate up to the response of the patient.
Administration rates: more than 50 mcg/kilogram per every minute is applied in very serious situations.
Normal Adult Dose of Dopamine for Shock:
Initial dose 1 to 5 mcg/kg/min using IV infusion continuously
Titration up to the response of the patient.
Administration at rates more than 50mcg per min is used in serious situation.
Usual Pediatric Dose for Non-Obstructive Oliguria:
Less than 1 month: 1 to 20 mcg/kg/min using IV infusion continuously and should be titrated up to the response of the patient.
1 month or more: 1 to 20mcg/kg/min using IV infusion continuously, the dose should be titrated up to the response of the patient. Not more than of 50mcg/kg/min.
There are hemodynamic effects caused by dopamine which occur due to the following situations:
- Low dosage: 1 to 5mcg/kg/min may urine output and renal blood flow.
- Intermediate dose: 5 to 15 mcg/kg/min it increases blood pressure, cardiac output, heart rate, cardiac contractility and renal blood flow.
- High dose: more than 15mcg/kg/min brings about alpha-adrenergic effects which begin to vasoconstriction, predominate and increase blood pressure.
Usual Pediatric Dose for Shock:
Less than 1 month: 1 to 20 mcg/kg/minute using IV infusion continuously, titration can be done to desired response.
1 month or more: 1 to 20 mcg/kg/minute using IV infusion continuously, titration May be done to desired response and not more than 50 mcg/kg/minute.
Hemodynamic effects of dopamine occur according to the dose taken:
- Low dosage: 1 to 5 mcg/kg/minute, increases urine output and renal blood flow.
- Intermediate dosage: 5 to 15 mcg/kg/min, increases blood pressure, cardiac output, cardiac contractility, heart rate and renal blood flow
- High dose: more than 15 mcg/kg/min brings about alpha- adrenergic effects that causes high blood pressure, vasoconstriction and predominate.
