Tramadol vs Lortab: Differences, Strength and Risks
How tramadol and Lortab compare as opioid painkillers, their strength, risks, addiction potential, and what to know about using either safely.
Clinically reviewed by Dr. Ponlawat Pitsuwan, Physician and Addiction Medicine Specialist, Phuket Island Rehab.
Tramadol and Lortab are both prescription opioid painkillers, but they differ in strength and how they work. Lortab combines hydrocodone with acetaminophen and is a Schedule II drug used for moderate to moderately severe pain; it is closely related to Norco. Tramadol is a weaker, Schedule IV opioid that also affects serotonin and norepinephrine, and is used for moderate pain. Lortab is generally stronger and has higher abuse and dependence potential, while tramadol carries its own risks, including seizures and serotonin syndrome, especially in combination with other medications. Both can cause tolerance, physical dependence, and addiction when misused, and both should only be taken exactly as prescribed by a doctor.
What each drug is
Lortab is a combination medication containing hydrocodone, a strong opioid, and acetaminophen. It is used to treat moderate to moderately severe pain and is closely related to other hydrocodone products such as Norco and Vicodin. Tramadol is a separate opioid that is generally considered weaker; in addition to acting on opioid receptors in the brain, it affects serotonin and norepinephrine, giving it a dual mechanism.
Both are prescription opioids, so both carry a genuine risk of tolerance, dependence, and addiction, but they are not equivalent drugs and their differences matter for safety.
Strength and scheduling
In the United States, Lortab is a Schedule II controlled substance, reflecting its high potential for abuse and dependence. Tramadol is Schedule IV, meaning a lower, though still real, abuse potential. In practical terms, the hydrocodone in Lortab is a stronger opioid than tramadol at usual doses, which is why Lortab is used for more severe pain.
| Feature | Tramadol | Lortab (hydrocodone/acetaminophen) |
|---|---|---|
| Opioid strength | Weaker opioid | Stronger opioid |
| DEA schedule | Schedule IV | Schedule II |
| Used for | Moderate pain | Moderate to moderately severe pain |
| Extra mechanism | Affects serotonin and norepinephrine | Contains acetaminophen |
| Notable risks | Seizures, serotonin syndrome | Liver harm from acetaminophen, higher dependence |
Risks and side effects
Both drugs share the typical opioid side effects: drowsiness, constipation, nausea, dizziness, and, at high doses, dangerously slowed breathing. Lortab’s acetaminophen can damage the liver at high doses, so exceeding the prescribed amount is doubly dangerous. Tramadol has distinctive risks: it can lower the seizure threshold and, because it affects serotonin, it can cause serotonin syndrome, particularly in combination with antidepressants or other serotonergic medications.
Addiction and dependence potential
People sometimes assume tramadol is safe because it is weaker and lower-scheduled, but this is a misconception, tramadol is still an opioid and can cause dependence and addiction. Lortab, being stronger, has a higher abuse and dependence potential. With either drug, taking more than prescribed, taking it for longer than needed, or using it to feel good rather than to treat pain are warning signs that use is becoming a problem.
Treatment for tramadol or Lortab addiction
Addiction to either opioid is treatable. Treatment usually begins with medically supervised detox to manage withdrawal, followed by therapy to address the reasons for use, and medication-assisted treatment where appropriate. Because both are opioids, the same evidence-based approaches apply, tailored to the patient’s history and needs.
The bottom line
Lortab (hydrocodone and acetaminophen) is generally the stronger opioid with higher abuse potential, while tramadol is weaker but carries its own risks of seizures and serotonin syndrome. Both are genuine opioids that can lead to dependence and addiction, and both must be used only as prescribed and under medical supervision.
