Mastering Common ICU Drips: A Nurse’s Guide to Lifesaving Medications

One of the most intimidating skills to learn as a new ICU nurse is confidently managing common ICU drips. In this guide, we break down meds (like Levophed, Dopamine, Propofol, etc.), what they do, how to titrate them, and key nursing tips. So you can feel safe, prepared, and confident.

These are powerful medications delivered directly into the patient’s circulatory system that often elicit immediate effects. While the physician decides when the medication is necessary and orders it, the nurse is the one who physically gives it to the patient, monitors its effects, and adjusts the dose as needed. It’s quite the responsibility to safely give all of these common ICU drips – but completely doable!

Your Guide to Common ICU Drips

In this comprehensive guide, we’ll delve into the trade names, generic names, starting doses, titration guidelines, potential complications, and essential nursing considerations for these vital infusions. All of these medications will be given through an infusion pump, which we discuss more in-depth in this blog post on common ICU equipment.

Important safety notes: This article is for general nursing education only and is not a medication-administration or titration protocol. Do not use the doses, ranges, or titration examples in this article independently to make patient-care decisions. Appropriate dosing and monitoring vary by indication, patient condition, medication concentration, vascular access, and institutional practice. Administer and titrate these high-alert medications only under an authorized patient-specific order or approved protocol. Always verify the medication, concentration, dose, titration parameters, monitoring requirements, compatibility, and route against your current institutional policy, pharmacy-approved drug reference, and product labeling. If this article conflicts with an order, protocol, pharmacist, prescriber, or institutional policy, stop and clarify before administering or changing the infusion. This article addresses general considerations for adult patients only. Pediatric, neonatal, obstetric, and other specialized populations require different guidance.

Nursing Tips for Common ICU Drips

Before we get into the meds themselves, here are some general tips on common ICU drips:

• Know what your goal is (a MAP over 65, for example).
• Ensure your bedside monitor’s alarms are set to go off if the patient’s vitals are out of range and require your action
• Label your IV lines close to the insertion site.
• If a blood pressure is extremely different from the previous readings, double-check it before titrating your drip
• If your blood pressure cuff is set to go off every 5, 10, 15, or more minutes, glance at it whenever you walk in the room to ensure it has not been accidentally turned off.
• Do not delay an urgently needed vasopressor solely while awaiting central access. When permitted by institutional policy, short-term peripheral administration should use a well-functioning IV in an appropriate proximal vein, with frequent site assessment and an established extravasation-response protocol. Avoid placing a blood pressure cuff on the same extremity when feasible. Transition to central access when clinically indicated; a large-bore catheter alone does not eliminate extravasation risk.
• All of these meds are serious and can cause major complications. We do not want them infusing any longer than necessary. Continually reevaluate the purpose of the med; if we’ve met our goal and if it is clinically appropriate/ordered, look to wean down the drip as the patient response dictates.
• Before combining any drips into a single line, ensure you check compatibility.
• If the patient is receiving a drip to increase their blood pressure, reevaluate all other meds (in particular scheduled oral meds) and clarify any meds that would decrease blood pressure. Many patients take oral blood pressure meds at home and they are often ordered on patients. Don’t blindly give them!

Ok, now that we’ve discussed some high-level considerations, let’s talk about some common ICU drips.

Specific ICU Medications

Dopamine (Intropin)

Generic Name: Dopamine

Possible Starting Dose: 5-10 mcg/kg/min

Possible Titration: Increase by 2-5 mcg/kg/min increments

Complications: Monitor for tachycardia, hypertension, extravasation, and ischemia. Be vigilant for signs of extravasation, which can lead to tissue necrosis.

Nursing Considerations: Assess blood pressure and heart rate frequently. Ensure a large-bore IV for administration to prevent extravasation.

This medication is given more often in a cardiac ICU than your standard ICU, but it is still one to know well. Extravasation is a big complication to watch out for, and it is most easily prevented by administering this medication into a central line rather than a peripheral IV.

Low-dose (“renal-dose”) dopamine should not be used to prevent or treat AKI. Although it may transiently change renal blood flow or urine output, it does not improve kidney recovery, reduce dialysis, or improve clinical outcomes and may cause tachyarrhythmias or myocardial ischemia.

Norepinephrine (Levophed)

Generic Name: Norepinephrine

Possible Starting Dose: 0.01-0.1 mcg/kg/min

Possible Titration: Increase by 0.01-0.1 mcg/kg/min increments

Complications: Watch for hypertension, tachycardia, extravasation, and decreased peripheral perfusion.

Nursing Considerations: Monitor blood pressure, heart rate, and peripheral perfusion closely. Administer through a central line to minimize extravasation risk.

You may hear this referred to as “Levo” on the nursing unit. Norepinephrine is the recommended first-line vasopressor for septic shock. Vasopressor selection in other shock states depends on the cause and hemodynamic profile. Assess and address hypovolemia promptly, while avoiding unnecessary delay in vasopressor initiation when shock persists. You will likely see this given for hypotension related to sepsis not responding to fluids.

Its half-life is very short, only 2.5 minutes, so if you have a patient on it and that is the only thing keeping their blood pressure up, make sure there are no interruptions to that drip! This means paying attention to when the bag is running low, replacing it promptly, and keeping your IV pump charged.

As an ICU nurse, you will likely give this medication every single shift; it is the most common ICU drip. Here’s a great free article that explains all of the intricacies of this medication. I highly recommend learning what you can about it, and paying close attention at the bedside when your preceptors, or more experienced colleagues, are discussing it.

Epinephrine (Adrenaline)

Generic Name: Epinephrine

Possible Starting Dose: 0.01-0.1 mcg/kg/min

Possible Titration: Increase by 0.01-0.1 mcg/kg/min increments

Complications: Be alert for tachycardia, hypertension, arrhythmias, and extravasation.

Nursing Considerations: Continuous ECG monitoring is essential. Administer through a central line whenever possible.

This is often referred to as “epi”. As an ICU nurse, you’ll give this most often in a code situation. The dosing during a code are intermittent IV push doses, rather than an actual drip. If a patient does not already have a central line in place prior to the code, it is appropriate to give epi in a peripheral IV. If the patient stabilizes but will require an epi drip, then you will want to get a central line. The intermittent emergency dosing is often non-weight-based, while the drip is often given based upon the patient’s weight in kilograms.

Watch out for an increased lactate level and renal issues. This med causes vasoconstriction to the kidneys. Likely, if your patient needs an epi drip, you’re monitoring BUN/Creatinine labs at least daily. Pay attention to urine output!

Vasopressin

Generic Name: Vasopressin

Possible Starting Dose: 0.01-0.04 units/min

Possible Titration: Adjust to achieve target blood pressure, but avoid exceeding 0.04 units/min (not always titrated; may be at a set rate)

Complications: Monitor for hypertension, decreased cardiac output, and hyponatremia.

Nursing Considerations: Frequent blood pressure monitoring is crucial. Watch for signs of fluid overload or hyponatremia.

This medication is often given to patients who are on increasing doses of norepinephrine that are unresponsive. It can help actually reduce the amount of norepinephrine needed. Adding vasopressin is a common aspect of a sepsis protocol.

You will likely see this as a set infusion rate, rather than a medication that you titrate when given for sepsis. It is currently recommended to infuse continuously at 0.03 units/min when added to norepinephrine, with an acceptable range of 0.01 – 0.04 units/min, but not to exceed 0.04 units/min.

Major clinical tip! If you are about to discontinue the vasopressin on a patient who is also on norepinephrine, it is now recommended to taper it slowly off, as clinically significant hypotension can occur. UpToDate currently recommends slowly tapering by 0.01 units/min every 30-60 minutes and watching MAP closely. (If they’re on 0.03 units/min, it won’t take more than three hours, at most, if they respond well.)

Remember: Always follow your institution’s dosing guidelines.

Insulin

Generic Name: Regular Insulin

Starting Dose: Start and titrate IV regular insulin only according to a validated, diagnosis-specific institutional protocol. The initial rate, glucose target, monitoring frequency, and whether a bolus is used vary by indication.

Titration: Adjust based on blood glucose levels, following a prescribed protocol.

Complications: Hypoglycemia is a significant risk. Monitor blood glucose closely.

Nursing Considerations: Check blood glucose levels at regular intervals. Administer through a dedicated line to prevent mixing with other infusions.

While this is a common ICU drip, it is based on a blood glucose reading rather than vital sign changes. The frequency of the blood sugar checks depends on the stability of their levels. During continuous IV insulin therapy, glucose is generally checked every 30 minutes to 2 hours according to a validated institutional protocol. Monitoring may need to be more frequent during initiation, rapid glucose changes, nutrition changes, interruptions, or hypoglycemia.

To see a very basic example of an ICU insulin infusion protocol, click here. This example is from 2008, but you can see how it is structured. Physicians select different algorithms. These vary based on how aggressive the physician wants to be in managing glucose, as patients can have very different goals and needs.

Any patient receiving insulin should have a hypoglycemia order set on their chart. This enables you to address and treat any episodes of hypoglycemia autonomously. To see a sample hypoglycemia protocol, click here. Note: This protocol is over a decade old and is only an example.

For critically ill patients, the current recommendation is to maintain a blood glucose level of 140-180 mg/dL. There is considerable variation, and there may be rationale for a more stringent approach rather than a more moderate one. Your ICU will likely have an established protocol.

Neosynephrine (Phenylephrine)

Generic Name: Phenylephrine

Possible Starting Dose: 20-100 mcg/min

Possible Titration: Increase by 20-50 mcg/min increments as needed

Complications: Be vigilant for hypertension, reflex bradycardia, and decreased cardiac output.

Nursing Considerations: Monitor blood pressure and heart rate closely. Administer through a central line to reduce the risk of extravasation.

This med is a treatment for hypotension, but it’s not first-line. (Remember which one is? Levophed!) It gets utilized most in the operating room for blood pressure management during general anesthesia. Severe bradycardia is a major complication to watch out for. This can reduce cardiac output, which is the exact opposite of what we want with a hypotensive patient. Because of this, if your patient has a history of heart failure, cardiogenic shock, severe coronary artery disease, heart block, or myocardial disease, it likely will not be used.

I personally saw this med used much more frequently in the neuro ICU rather than the cardiovascular ICU, as the patients in a neuro ICU are there for a brain issue and not a heart issue.

Fun fact: It is also available over the counter to treat nasal decongestion!

Propofol (Diprivan)

Generic Name: Propofol

Starting Dose: For continuous ICU sedation of intubated, mechanically ventilated adults, propofol is typically started at 5 mcg/kg/min and titrated slowly according to the medication order, institutional protocol, and patient response.

Titration: Adjust to the prescribed sedation goal, commonly using a validated scale such as the Richmond Agitation-Sedation Scale (RASS). Use the lowest effective dose and reassess the need for sedation regularly.

Complications: Hypotension, bradycardia, delirium, respiratory depression or apnea, hypertriglyceridemia, and infection related to improper handling. Propofol provides sedation and amnesia but does not provide analgesia, so pain must be assessed and treated separately.

Propofol infusion syndrome is a rare but potentially fatal complication, particularly with prolonged or high-dose infusions. Concerning findings include otherwise unexplained metabolic acidosis, hyperkalemia, rhabdomyolysis, acute kidney injury, ECG changes, bradyarrhythmias, or cardiac failure. Notify the appropriate clinician immediately and follow institutional protocols if these findings develop.

Nursing Considerations: Continuously monitor oxygenation, ventilation, blood pressure, heart rhythm, sedation depth, and overall clinical response. Because propofol can rapidly cause apnea and cardiovascular instability, airway-management and resuscitation capabilities must be immediately available. Continuous propofol infusion for ICU sedation is generally used in intubated, mechanically ventilated patients; propofol may also be used for procedural sedation under appropriately qualified supervision and monitoring.

Propofol is supplied in a lipid emulsion that supports microbial growth. Use strict aseptic technique, minimize line manipulations, and follow the specific product labeling and institutional policy for container and tubing changes. For Diprivan, discard the vial or container, unused medication, and dedicated administration tubing after 12 hours during ICU sedation. Do not extend use to 24 hours unless the exact product labeling and institutional policy explicitly permit it.

Monitor triglycerides during prolonged infusions according to institutional policy. Account for calories provided by the lipid emulsion when evaluating enteral or parenteral nutrition. Never abruptly interrupt an infusion when doing so could leave the patient inadequately sedated; anticipate bag and tubing changes and coordinate any interruption safely.

Common ICU Drips: Final Thoughts

ICU drips can feel intimidating at first, but you do not need to memorize everything overnight. With repetition, a reliable safety routine, and a clear understanding of what each medication is intended to accomplish, managing these infusions will gradually become a normal part of your workflow.

Remember ➡️ The possibility of harm in the absence of diligence is profound in the ICU. Develop a consistent routine and double-check every infusion when you assume care of a patient. I always verify the medication, concentration, dose, patient weight, infusion site, tubing, pump settings, remaining volume, and ordered goal, even when I trust the nurse giving me report.

Drip management, however, is only one part of becoming a confident ICU nurse. You are also learning how to assess critically ill patients, recognize subtle changes, understand ventilators and equipment, respond to emergencies, prioritize competing needs, and communicate effectively with the interdisciplinary team. Those skills do not exist in isolation; they work together every time you care for an unstable patient.

That is exactly why I created Breakthrough ICU.

It takes you beyond individual medications and helps you understand the bigger picture of critical care, so you can connect what you see at the bedside with what you need to do next.
