For many EMS providers, pain management is one of the most frequent — and most scrutinized — decisions made in the field.

The Sarasota County Fire Department recently updated its pain-management protocols, making intravenous acetaminophen the first-line medication for moderate-to-severe pain and removing opioids from front-line apparatus. Department officials said opioids would still be available under appropriate oversight when clinically necessary.

The announcement quickly sparked debate among EMS providers, with many questioning whether IV acetaminophen is effective enough for severe pain — and whether removing opioids from front-line units limits provider judgment.

Here’s what EMS1 readers had to say.

“Use it — but don’t take away clinical judgment”

Several readers said IV acetaminophen can be a valuable tool, but warned against rigid protocols that limit provider discretion.

“Glad to see them have acetaminophen as a choice for analgesia. But, to replace opiates and not to allow provider judgment to select the best med for the situation says that the system does not trust its people.”

“IV acetaminophen should be considered first, but not as an absolute. The situation/injury dictates whether an opioid should be used or not.”

“Not sure about replace as (IMHO) opioids still have their place but certainly a long overdue complement to opioid analgesia.”

Others echoed the need for flexibility paired with strong education.

“While I am including this in our agency protocols, I’m not restricting my clinicians’ ability to treat pain appropriately with ALL of their pharmaceutical resources, including opioids. But allowing your front-line providers, not just your supervisors, to be clinicians and to make those choices requires a significant amount of training that is often challenging for agencies to maintain.”

“Patients don’t always want opioids”

Some EMS professionals shared positive experiences using IV acetaminophen, particularly with patients who are opioid-averse.

“This could be a great option for those with opioid tolerance or fear of opioids. We have two state prisons within our run district. I cannot tell you how many patients, from those institutions, legitimately were appropriate for pain control, but became very fearful at the mention of fentanyl.”

“We use it in the observation department and it works great. Less opioid use for sure. Patients really seem to like it. So many patients don’t want opioids. Add Toradol and it’s even better.”

“As a paramedic in San Diego CA, I have had great success with IV Tylenol and just used it today!”

One reader pointed to data showing system-wide benefits.

“Our EMS system in the Chicagoland area implemented this change several months ago, and the results have been very positive. Data show no significant difference between pre- and post-administration pain scores when comparing acetaminophen to fentanyl. Additionally, the frequency of pain management interventions has increased since the change.”

“IV Tylenol is not enough for severe pain”

Other readers strongly disagreed with using IV acetaminophen as a replacement for opioids in serious cases, arguing it is insufficient for severe trauma and acute pain.

“This is terrible! Severe pain needs fast-acting opioids, not Tylenol.”

“I do not think Tylenol should be used in dire situations.”

“This is going to be like peeing on a brush fire for pain management. Pt will hate us.”

Several comments criticized the decision more harshly.

“No, this is ridiculous and borderline torture.”

“That is medical abuse. There is not a study that supports IV Tylenol is a better option to treat moderate to severe pain in any situation.”

One anesthesia provider weighed in with clinical experience from outside the prehospital environment.

“As an anesthesia provider, that has extensive use of IV acetaminophen, and have also been published for IV acetaminophen use in the OR setting, I can tell you it does not treat moderate to severe pain anywhere near what opioids like morphine and Dilaudid can do. This is not a good move.”

“Reduce opioids — don’t eliminate them”

A common theme across responses was compromise: reduce opioid use when appropriate, but don’t remove them entirely.

“If it works then yes. We have to remember morphine, as an example, is also given for side effects such as CHF and the venous pooling effects. Use of opioids should not be eliminated. Reduced yes but not eliminated.”

“I do believe that would be a great idea. Maybe even the AEMT could be written in their protocol as well.”

More EMS1 reader responses:

  • “The decision on which analgesic to use should be left up to the provider and be based on the patient’s approval and overall extent of their pain.”
  • “It was a great first choice and experienced firsthand that it can work as well as an opioid derivative. After weeks of excruciating headaches went to ER hoping for mri/scan. They wanted to give me an opiate; however, I refused as do not like or tolerate the mind-altering feelings it gives. Was able to get pain relief and still able to make clear decisions for self after finding small brain bleeds.”
  • “It has been in scope in New Mexico for several years. We have only recently started using it in our service. We still use opiates as well as IV Toradol and PO Ibuprofen and acetaminophen it is the providers discretion. As a winter and summer recreation destination we see a wide variety of pain calls. When removing ski gear internasal fentanyl is usually the best option then often followed up by IV Tylenol, But in most of our trauma calls opiates are much more effective than Tylenol. IV Tylenol has proven very effective in non-traumatic pain.”
  • “Should IV acetaminophen replace narcotic analgesics for moderate to severe pain? In my opinion, no. We added IV acetaminophen to our guidelines 8 years ago when it was under the brand name Ofirmev. While it is more effective than PO APAP, it does not provide the same level of analgesia as narcotics for moderate to severe pain. In my experience, IV acetaminophen is very effective for mild pain. However, for moderate to severe pain, it is best utilized as part of a multimodal approach rather than as a replacement for narcotics. When administered with fentanyl or ketamine, it can reduce the total amount of narcotics required and improve overall pain control. As with any pain management strategy, every patient is unique. Effective pain control requires flexibility and a variety of therapeutic options to ensure we are meeting individual patient needs safely and appropriately.”
  • “I see what the problem is. The use of IV acetaminophen, Ofirmev, requires training, experience and the acceptance by medical directors that paramedics do practice medicine in the field and require options rather than edicts. Given the state of liability and resistance in the medical community to acknowledge reality, it’s no wonder there’s a knee-jerk response on both sides of the debate. With more than a century experience covering every aspect of EMS, I say IV Tylenol has its place, is a valuable addition to the prehospital war chest but will never replace opioid. Quantitative pre-hospital studies are required to settle the debate; the faster, the better.”
  • “My service has just implemented the use of IV acetaminophen for pain, but we still have the option to use opioid medications if we deem there is a need for it. A lot of our older population refuse pain medications due to the fear of addiction. In those cases, the IV acetaminophen helps ease their mind but not always their pain. I think this is a great initial strategy but keep the opioids for the real pain for our patient’s sake.”
  • “Let the paramedics use their clinical judgment! IV Acetaminophen is a great tool to have, but don’t take the opioids away. A burn victim for instance can’t get enough relief from some opioids so Tylenol would be inappropriate. Leave it up to the medic!”
  • “Let’s add it!”
  • “It’s been my experience that opioids are a necessary protocol for acute pain especially if you have a patient that has been on an opioid regimen for prolonged acute pain management. IV acetaminophen would have the same effect as IV saline on these patients. As a first protocol it’s a non starter for the vast majority of acute pain patients.”
  • “I think IV acetaminophen is a good addition to our choices of pain relievers. But eliminating opioids all together is not a good choice. Acetaminophen would work fine for minor to moderate pain. But for severe pain MS or something similar should still be available. A well-trained paramedic should be able to make the choice. I think we need more studies with it to determine how often it really does work.”
