Schedule of Controlled Medications
Define the five DEA schedules of controlled medications and identify representative drugs in each.

The Five Schedules

The Drug Enforcement Administration classifies controlled substances into five schedules. Abuse potential decreases as the schedule number increases. Schedule I has the highest abuse potential and no accepted medical use. Schedule V has the lowest abuse potential and routine medical use.

ScheduleExamplesAbuse PotentialMedical UseDependence
Schedule IHeroin, LSD, marijuana, Ecstasy (MDMA)HighNone accepted; research, analysis, or instruction only
Schedule IIMorphine, meperidine (Demerol), fentanyl (Actiq), codeine, oxycodone, opium, amphetaminesHighAcceptedMay lead to severe physical and/or psychological dependence
Schedule IIIBuprenorphine (Suboxone), acetaminophen with codeine (Tylenol #3), ketamine (Ketalar), anabolic steroidsLess than Schedule I and IIAcceptedModerate or low physical dependence, or high psychological dependence
Schedule IVMidazolam (Versed), alprazolam (Xanax), zolpidem (Ambien)Lower than Schedule IIIAcceptedLimited physical or psychological dependence
Schedule VDiphenoxylate (Lomotil), guaifenesin and codeine (Robitussin AC)Lower than Schedule IVAcceptedLimited physical or psychological dependence
⚠ Common Confusion — Schedule of TCCC DrugsFentanyl is Schedule II. Ketamine is Schedule III. Midazolam is Schedule IV. These three appear together in pain control, but they sit in different schedules. The test will swap their schedules.
Caution with AviatorsAny aviator who receives controlled substances must be cleared by a flight surgeon before returning to flight status. Document medication administration carefully in the field.

TCCC Phases and Medication Categories
Identify the TCCC phases of care and the four categories of medications used in TFC and TACEVAC.

Phases of TCCC

1
Point of Injury — the moment trauma occurs.
2
Care Under Fire / Threat — treatment provided while still under hostile threat. Pharmacology is minimal here.
3
Tactical Field Care (TFC) — threat is reduced. This is where pharmacological treatment is initiated.
4
Tactical Evacuation Care (TACEVAC) — care during evacuation. Pharmacology is continued from TFC.

Four TFC / TACEVAC Medication Categories

CategoryPurpose
PainCombat Wound Medication Pack, fentanyl, ketamine
BleedingTranexamic acid (TXA); calcium gluconate or calcium chloride after blood products
InfectionCefazolin, metronidazole, moxifloxacin, ertapenem, ceftriaxone
OtherNaloxone, ondansetron, promethazine, midazolam, epinephrine, diphenhydramine, lidocaine
Initiate vs ContinuePharmacology is initiated in Tactical Field Care and continued in Tactical Evacuation Care. Care Under Fire does not include drug administration beyond what is absolutely required to stop massive bleeding.
3
JTS TCCC — Treating Pain (Three Options)
Identify the specific medications used in TFC / TACEVAC to treat pain under the JTS TCCC algorithm.

The Decision Tree

JTS TCCC triages pain treatment by two questions. First, how severe is the pain? Second, what is the casualty’s physiological status? The combination produces three options.

OptionPain LevelCasualty StatusTreatment
Option 1Mild to ModerateStill able to fightTCCC Combat Wound Medication Pack (CWMP)
Option 2Mild to ModerateNOT in shock or respiratory distress AND NOT at risk of developing eitherOral transmucosal fentanyl citrate, or fentanyl IN, or fentanyl IV
Option 3Moderate to SevereIS in shock or respiratory distress, OR at significant risk of developing eitherKetamine IN, IM, IV, or IO

Option 1 — Combat Wound Medication Pack (CWMP)

  • Acetaminophen (Tylenol) — 500 mg tablet, 2 PO every 8 hours.
  • Meloxicam (Mobic) — 15 mg PO once daily.

Option 2 — Fentanyl

  • Oral transmucosal fentanyl citrate (Actiq) — 800 micrograms.
  • Fentanyl (Sublimaze) intranasal — 100 micrograms.
  • Fentanyl (Sublimaze) intravenous — 50 micrograms, or 0.5 to 1 microgram per kilogram.

Directions for OTFC Lozenge

1
Place the lozenge between the cheek and the gum.
2
Tape the lozenge-on-a-stick to the casualty’s finger as a safety measure.
3
Add a second lozenge in the other cheek if necessary to control severe pain.
4
Do not chew the lozenge.
5
Reassess in 15 minutes.
6
Monitor for respiratory depression.

Option 3 — Ketamine

  • Ketamine (Ketaset) IN or IM — 50 to 100 mg, or 0.5 to 1 mg per kilogram.
  • Ketamine (Ketaset) slow IV or IO push — 20 to 30 mg, or 0.2 to 0.3 mg per kilogram.
Why Ketamine for Shock or Respiratory DistressOpioids like fentanyl cause respiratory depression and lower blood pressure. A casualty already in shock or struggling to breathe cannot tolerate that. Ketamine preserves respiratory drive and supports blood pressure, which is why it is the choice when the casualty is unstable.
4
2025 Ranger Medic Handbook — Treating Pain
Identify the medications used to treat pain under the 2025 RMHB algorithm using a 1–10 severity scale.

The Three Severity Tiers

The Ranger Medic Handbook uses a numeric pain scale rather than the binary mild-moderate / moderate-severe split used by JTS TCCC. The tiers are 1–3 (mild), 4–6 (moderate), and 7–10 (severe).

Mild Pain (1–3) — Casualty Still Able to Fight

Use the Combat Wound Pill Pack: Tylenol 1,000 mg PO single dose AND Mobic 15 mg PO single dose. Consider as alternatives:

  • Ibuprofen — 600 mg PO three times daily.
  • Naproxen — 250 to 500 mg twice daily.
  • Ketorolac — 30 mg IM, or 15 mg IV, twice daily.

Moderate Pain (4–6) — NOT in Shock or Respiratory Distress

Casualty is not at risk of developing shock or respiratory distress. Consider:

  • Fentanyl lozenge — 1600 micrograms PO as needed.
  • Ketamine — 0.1 to 0.3 mg per kilogram IV or IO, or 0.5 mg per kilogram IM or IN, every 30 minutes as needed.
  • Hydromorphone — 0.25 to 0.5 mg IV or IO every hour as needed.

Severe Pain (7–10) — IS in Shock or Respiratory Distress or At Risk

  • Ketamine — 0.1 to 0.3 mg per kilogram IV or IO, or 0.5 to 1 mg per kilogram IM or IN, every 30 minutes as needed.
  • Hydromorphone — 0.5 to 1 mg IV or IO every 30 minutes as needed; titrate to effect.
  • Fentanyl — 0.5 to 1 microgram per kilogram IV or IO every 30 minutes as needed.

Adjuncts (All Tiers)

  • Midazolam — 2 to 5 mg IV with ketamine or opioids for anxiolysis or sedation.
  • Ondansetron — 8 mg IV, IM, or sublingual every 8 hours as needed for nausea or vomiting.
  • Consider a nerve block for extended evacuation times and drug-limited environments.
  • Reassess pain and titrate dosage as needed.
⚠ TCCC vs RMHB Dosing DifferencesThe RMHB doses fentanyl by weight (0.5 to 1 microgram per kilogram IV) at the severe tier. TCCC gives a fixed 50 microgram IV dose at the moderate tier. Hydromorphone appears in RMHB but is not in the TCCC pain algorithm.
5
Analgesia and Sedation Rules
Identify the safety rules governing the use of opioids, ketamine, and benzodiazepines in TCCC.

Core Rules

  • Casualties must be disarmed after being given OTFC, intravenous fentanyl, ketamine, or midazolam.
  • The goal of analgesia is to reduce pain to a tolerable level while still protecting the airway and mentation.
  • The goal of sedation is to stop awareness of painful procedures. Sedation is Option 4 for pain control and is taught during Prolonged Field Care in Trauma 3.
  • Document a mental status exam using the AVPU method (Alert, Verbal, Painful, Unresponsive) before administering opioids or ketamine.
  • Use caution with these drugs in traumatic brain injury patients. They make it harder to perform a neurologic exam or detect decompensation.

If Respirations Drop

1
Reposition the casualty into a “sniffing position” to open the airway.
2
If that fails, provide ventilatory support with a bag-valve-mask or mouth-to-mask ventilations.
3
Naloxone (Narcan) — 0.4 mg IV, IM, or IN should be available whenever opioid analgesics are used.

Benzodiazepines — What Not to Do

  • The routine use of benzodiazepines such as midazolam (Versed) is NOT recommended for analgesia.
  • Benzodiazepines should not be used prophylactically.
  • They are not commonly needed when the correct pain or sedation dose of ketamine is used.
  • Polypharmacy is not recommended. Benzodiazepines should NOT be used in conjunction with opioid analgesia.

Monitoring

For all casualties given opioids, ketamine, or benzodiazepines, monitor airway, breathing, and circulation closely.

The Naloxone ReflexIf you give opioids, naloxone must be within arm’s reach. This is not optional. Respiratory depression from fentanyl can kill a casualty before evacuation lands.
6
Treating Bleeding — TXA and Calcium
Identify the indications, doses, and routes for tranexamic acid and calcium products in TCCC.

Indications for TXA

Administer tranexamic acid if a casualty meets either of the following criteria.

  • Will likely need a blood transfusion. Examples: hemorrhagic shock, elevated lactate, one or more major amputations, penetrating torso trauma, or evidence of severe bleeding.
  • Has signs or symptoms of significant traumatic brain injury, or has altered mental status associated with blast injury or blunt trauma.

Tranexamic Acid (TXA, Cyklokapron)

FieldDetail
Dose2 grams
RouteSlow IV or IO push
TimingAs soon as possible, but NOT later than 3 hours after injury

Calcium Gluconate

FieldDetail
IndicationFor use after blood product transfusions
RouteIV or IO
Dose1 gram = 30 mL of 10% solution

Calcium Chloride

FieldDetail
IndicationFor use after blood product transfusions
RouteIV or IO
Dose1 gram = 10 mL of 10% solution
Calcium Chloride CautionCalcium chloride has been associated with severe necrosis and skin sloughing when extravasation occurs during peripheral IV administration. Monitor the infusion closely. Use only if calcium gluconate is not available.
⚠ TXA Window is Three HoursIf injury occurred more than 3 hours ago, do NOT give TXA. After that window, TXA can increase mortality. The 3-hour cutoff is a hard limit.
7
Treating Infection — Antibiotic Selection by Injury Pattern
Identify the specific antibiotics used in TFC / TACEVAC to treat or prevent infection based on injury type.

Infection Control CPG Key Principles

  • Standard Precautions — hand hygiene and personal protective equipment.
  • Surgical Site Infection (SSI) Prevention — prophylactic antibiotics preoperatively, proper skin preparation, postoperative monitoring.
  • Open Wound Management — control bleeding, apply sterile dressings, ensure appropriate follow-up.

Cefazolin (Ancef) — The Default

Dose: 2 grams IV every 6 to 8 hours. Indicated for:

  • Penetrating brain injury
  • Open maxillofacial fractures
  • Maxillofacial fractures WITH foreign body or fixation device
  • Penetrating chest injury without esophageal disruption
  • Penetrating spinal cord injury
  • Skin and soft tissue, no open fractures
  • Skin and soft tissue, WITH open fractures, exposed bone, or open joints

Cefazolin AND Metronidazole — When Anaerobic Coverage Is Needed

Add metronidazole (Flagyl) 500 mg IV every 8 to 12 hours to cefazolin for:

  • Penetrating brain injury if gross contamination with organic debris
  • Penetrating chest injury with esophageal disruption
  • Penetrating spinal cord injury if the abdominal cavity is involved
  • Penetrating abdominal injury with suspected or known hollow viscus injury and soilage; rectal or perineal injuries

Expected Delay to Reach Surgical Care — Oral Option

DrugDoseRoute
Moxifloxacin (Avelox)400 mgPO x 1 dose

Use moxifloxacin PO if the casualty can tolerate oral medications and does NOT have penetrating abdominal injury or shock.

Expected Delay — IV/IM Options

ScenarioDrugDoseRoute
Penetrating abdominal injury, shock, or unable to tolerate POErtapenem (Invanz)1 gramIV or IM
Penetrating head injury, shock, or unable to tolerate POCeftriaxone (Rocephin)1 to 2 gramsIV or IM
⚠ Cefazolin vs CeftriaxoneBoth are cephalosporins. Cefazolin (Ancef) is the routine prophylactic. Ceftriaxone (Rocephin) is used specifically for penetrating head injury when oral antibiotics cannot be tolerated. Do not swap them.
8
Treating Other Conditions
Identify the medications used in TFC / TACEVAC for opioid reversal, nausea, sedation, anaphylaxis, and local anesthesia.

Opioid Reversal

DrugDoseRouteUse
Naloxone (Narcan)0.4 mgIV, IO, or IMReverse opioid-induced respiratory depression

Nausea and Vomiting

DrugDoseRoute
Ondansetron (Zofran)4 mgOral disintegrating tablet, IV, IO, or IM
Promethazine (Phenergan)12.5 to 25 mgPO, IV, or IM

Sedation / Anxiolysis

DrugRouteNote
Midazolam (Versed)IN, IO, IV, or IMNOT for analgesia. Used for sedation or seizure. Not given alongside opioids.

Anaphylaxis

DrugRouteRole
Epinephrine (Adrenalin)IMFirst-line. Reverses bronchospasm and hypotension.
Diphenhydramine (Benadryl)PO, IV, or IMAntihistamine adjunct. Does not replace epinephrine.

Local Anesthesia

DrugRoute
Lidocaine (Xylocaine)IV or IM
Anaphylaxis SequenceEpinephrine first, always. Diphenhydramine is an adjunct, not a substitute. Giving Benadryl without epinephrine in a true anaphylactic reaction can let a casualty die from airway swelling while you wait for it to work.

Highlights — What Changes from TCCC

  • MASCAL — PCC events often start with multiple casualties combined with lack of evacuation resources.
  • Nursing Care — not a traditional combat medic skill, but a vital component of PCC.
  • Communication — important in TCCC, even more important across larger times and distances and for ICU-level patients.
  • Logistics — almost always a problem. Requires contingency planning and creative thinking.

The 13 Steps of PCC

1
Initial TCCC management. Solid TCCC is the foundation of competent PCC.
2
Delineate roles and responsibilities. Combat is a team sport; so is PCC.
3
Perform comprehensive physical exam and detailed history with problem list and care plan. Get organized.
4
Record and trend vitals. This is a key task in PCC.
5
Perform teleconsultation. Needs a format and pre-coordinated contact info.
6
Create a nursing plan.
7
Implement a rest and chow plan.
8
Anticipate resupply and electrical issues. Logistics are always a problem.
9
Perform periodic mini rounds. Comprehensive reassessment based on trending vitals and patient condition.
10
Obtain and interpret lab studies. What would you like? What can you get? Who do you need to consult?
11
Perform necessary surgical procedures. Level of training, risk vs reward, logistical requirements.
12
Prepare for transport / evacuation. Am I going with the patient? How long is the transport? What do we need logistically (drugs, fluids, hypothermia protection)?
13
Prepare documentation for patient handover. Trending vitals, drugs, ins and outs.

Midazolam2 to 5 mg IV with ketamine or opioidsFor anxiolysis or to manage ketamine emergence; respiratory depression risk increases when combined

PCC Antibiotics — Alternative Selections by Injury

If transitioning from ertapenem (Invanz) to moxifloxacin, begin moxifloxacin immediately after the final dose of ertapenem for antibiotic overlap. If using moxifloxacin only, administer 400 mg PO daily for 10 days. If using ertapenem only, administer 1 gram IV or IO or IM daily for 10 days.

Other PCC Considerations

  • Oral care: toothbrush, tooth paste, chapstick.
  • Eye drops: intubated or sedated.
  • Multi-vitamins PO daily.
  • Animal bites: rabies vaccine and rabies immunoglobulin.
  • HIV prophylaxis: exposure from combat (civilians or enemy forces). Follow PEP guidance.
  • Regional medications: continuing prophylaxis (malaria, etc).
⚠ Antipyretic CautionUse caution with NSAIDs in urgent or priority patients. Ensure the patient can void normally (no impaired renal function) before giving meloxicam or ketorolac.
Regional Anesthesia NoteIn some cases, local anesthetics or even limited regional anesthesia is the best option for pain control. For more information, see the Military Analgesia Regional Anesthesia Guidelines. While side effects are real and toxic levels of these drugs must be understood and avoided, the benefit can often be achieved without sedation when appropriate for the tactical environment.
