Lortab vs Vicodin: What Is the Difference?
How Lortab and Vicodin compare, why both are hydrocodone and acetaminophen, the differences between them, and the shared risks of side effects, addiction, and overdose.
Clinically reviewed by Dr. Ponlawat Pitsuwan, Physician and Addiction Medicine Specialist, Phuket Island Rehab.
Lortab and Vicodin are two brand names for essentially the same medication: a combination of the opioid hydrocodone and the pain reliever acetaminophen, used to treat moderate to moderately severe pain. Because they contain the same two active ingredients, Lortab and Vicodin work the same way and carry the same effects and risks; the main differences are the brand and the specific dosage combinations each has been available in, which can vary the ratio of hydrocodone to acetaminophen. Norco is another brand of the same hydrocodone and acetaminophen combination. As prescription opioids, all of these carry the same important risks: common side effects such as drowsiness, constipation, nausea, and dizziness; the danger of dependence and addiction with an opioid; the risk of dangerous breathing problems and overdose, especially at high doses or combined with alcohol or other sedatives; and the risk of liver damage from the acetaminophen if too much is taken. Lortab and Vicodin should be taken only as prescribed, never combined with alcohol or other sedatives without medical advice, and the total acetaminophen intake kept within safe limits. If use of either has become hard to control, that is a signal to seek help, and opioid addiction is treatable.
Lortab vs Vicodin: are they the same?
Lortab and Vicodin are, for practical purposes, the same medication sold under two different brand names. Both are a combination of two ingredients: hydrocodone, an opioid pain reliever, and acetaminophen (also known as paracetamol), a non-opioid pain reliever and fever reducer. This hydrocodone and acetaminophen combination is used to treat moderate to moderately severe pain, with the two ingredients working together, the opioid acting on the brain and nervous system to reduce the perception of pain, and the acetaminophen adding further pain relief. Because Lortab and Vicodin contain the same active ingredients, they work in the same way, produce the same effects, and carry the same risks. Norco is yet another brand name for the same hydrocodone and acetaminophen combination.
This article explains how Lortab and Vicodin compare, why they are essentially the same drug, what differences do exist between them, and the important risks they share as prescription opioid medications. The key point is that anyone comparing Lortab and Vicodin is really comparing two brands of one combination medication, so the choice between them is rarely about meaningful differences in effect and more about brand, availability, and the specific dosage strengths a doctor prescribes. Most importantly, because both contain an opioid and acetaminophen, they share the same serious risks, addiction, overdose, dangerous breathing problems, and liver damage from too much acetaminophen, which anyone taking either medication needs to understand and respect.
Why they are essentially the same
Lortab and Vicodin are essentially the same because they contain the same two active ingredients in the same kind of combination: hydrocodone and acetaminophen. The hydrocodone is the opioid component, responsible for the strong pain relief and also for the medication’s potential to cause euphoria, dependence, and addiction, while the acetaminophen adds pain relief and is the component that can damage the liver if too much is taken. Since both brands deliver this same hydrocodone and acetaminophen combination, they have the same mechanism, the same therapeutic effect on pain, the same side effects, and the same risks. A person taking an equivalent dose of either would experience essentially the same thing.
The differences that do exist are mostly about branding and formulation details rather than how the drug works. Over the years, Lortab and Vicodin have been available in various dosage combinations, differing in the amount of hydrocodone and acetaminophen per tablet, and these specific strengths have changed over time, including reductions in the maximum acetaminophen content for safety. So a particular Lortab tablet and a particular Vicodin tablet might contain slightly different amounts of the ingredients, which is why the exact dosage prescribed matters more than the brand name. There can also be differences in inactive ingredients and available forms (for example, tablets versus liquid). But none of these change the fundamental fact that Lortab, Vicodin, and Norco are brands of the same opioid-acetaminophen combination, with the same effects and the same risks.

| Used for | Moderate to moderately severe pain | Moderate to moderately severe pain |
| How it works | Same | Same |

Shared side effects
Because Lortab and Vicodin are the same combination medication, they share the same side effects, which are those typical of opioids plus the considerations of acetaminophen. Common side effects include drowsiness, dizziness, lightheadedness, nausea, vomiting, and constipation, which is a very common and often persistent opioid effect. Some people experience dry mouth, itching, or a feeling of being foggy or sedated. Many of these effects are most noticeable when starting the medication or after a dose increase and may ease over time, though constipation often persists and may need managing. As with any opioid, these side effects mean a person should be cautious about driving or operating machinery until they know how the medication affects them.
More serious side effects are possible and require prompt medical attention. The most important is respiratory depression, slowed or difficult breathing, which is the main danger of opioids and can be life-threatening, particularly at high doses or when the medication is combined with alcohol, benzodiazepines, or other sedatives. Other serious effects include serious allergic reactions, very low blood pressure and fainting, and, from the acetaminophen component, liver damage if too much is taken. Because both Lortab and Vicodin contain acetaminophen, it is important not to exceed the safe daily limit of acetaminophen and to be careful not to take other products that also contain it, since accidental overdose of acetaminophen can cause severe, even fatal, liver injury. These shared serious risks apply equally to both brands.
Shared risks: addiction and overdose
As prescription opioids, both Lortab and Vicodin carry a real risk of dependence and addiction because of their hydrocodone content. With regular use, the body becomes physically dependent, so that stopping suddenly causes withdrawal symptoms such as anxiety, restlessness, sweating, muscle aches, and trouble sleeping, which is why these medications should be tapered rather than stopped abruptly after prolonged use. Beyond physical dependence, the opioid can produce euphoria, which gives these medications a potential for misuse and addiction: taking more than prescribed, taking them to get high, or using them without a prescription is misuse and can lead to a substance use disorder. Anyone taking Lortab or Vicodin should use them exactly as prescribed and be alert to signs that use is becoming hard to control.
The most serious shared risk is overdose. Taking too much hydrocodone can dangerously suppress breathing, which can be fatal, and this risk is greatly increased when the medication is combined with alcohol, benzodiazepines, or other sedatives, which is one of the most common causes of opioid overdose deaths. Separately, the acetaminophen component poses a risk of severe liver damage in overdose. A suspected opioid overdose, with very slow or stopped breathing, severe drowsiness, or unresponsiveness, is a medical emergency requiring immediate help and naloxone if available. The reassuring message is that opioid addiction is treatable, with medication-assisted treatment, counselling, and support. If your use of Lortab, Vicodin, or any opioid has become hard to control, or you find yourself taking more than prescribed, that is a signal to seek help, and effective treatment is available.
Summary
Lortab and Vicodin are two brand names for essentially the same medication: a combination of the opioid hydrocodone and the pain reliever acetaminophen, used to treat moderate to moderately severe pain. Because they contain the same two active ingredients, Lortab and Vicodin work the same way and carry the same effects and risks; the main differences are the brand and the specific dosage combinations each has been available in, which can vary the ratio of hydrocodone to acetaminophen. Norco is another brand of the same combination. As prescription opioids, all of these carry the same important risks: common side effects such as drowsiness, constipation, nausea, and dizziness; the danger of dependence and addiction; the risk of dangerous breathing problems and overdose, especially at high doses or combined with alcohol or other sedatives; and the risk of liver damage from the acetaminophen if too much is taken. Lortab and Vicodin should be taken only as prescribed, never combined with alcohol or other sedatives without medical advice, and the total acetaminophen intake kept within safe limits. If use of either has become hard to control, that is a signal to seek help, and opioid addiction is treatable.
As Dr. Ponlawat Pitsuwan, addiction medicine specialist at Phuket Island Rehab, puts it, “Patients sometimes ask me whether Lortab or Vicodin is stronger or safer, and I have to explain that they are really the same medicine, hydrocodone and acetaminophen, just different brands, like Norco. So the comparison that matters is not Lortab versus Vicodin, it is understanding that both are opioids with all the risks that brings: addiction, dangerous breathing problems if mixed with alcohol or sedatives, and liver harm from the acetaminophen if you take too much. Take them exactly as prescribed, and if you find your use creeping beyond that, come and talk to us, because opioid addiction is very treatable.”
Frequently asked questions
What is the difference between Lortab and Vicodin?
There is very little meaningful difference: Lortab and Vicodin are two brand names for the same combination medication, hydrocodone (an opioid) plus acetaminophen (a non-opioid pain reliever), used for moderate to moderately severe pain. Because they contain the same active ingredients, they work the same way and carry the same effects and risks. The differences are mainly the brand name and the specific dosage strengths each has been available in, meaning the exact amounts of hydrocodone and acetaminophen per tablet can vary between products, which is why the prescribed dosage matters more than the brand. There can also be differences in inactive ingredients and available forms. Norco is another brand of the same combination. So when comparing Lortab and Vicodin, the practical answer is that they are essentially the same drug, and what matters most is the dose and the shared opioid risks.
Is Lortab or Vicodin stronger?
Neither is inherently stronger, because they are the same combination of hydrocodone and acetaminophen. Any difference in strength comes not from the brand but from the specific dosage of a given tablet, that is, how much hydrocodone and acetaminophen it contains. A Lortab and a Vicodin tablet with the same amounts of hydrocodone and acetaminophen are equally strong and have the same effect. Over the years both have been available in various strengths, so it is possible for a particular Lortab tablet to contain more or less hydrocodone than a particular Vicodin tablet, but this is about the specific product prescribed, not the brand being stronger overall. This is why the dose written on the prescription is what matters. If you have questions about the strength of your medication, your doctor or pharmacist can tell you exactly how much of each ingredient your specific tablets contain.
Are Lortab and Vicodin addictive?
Yes, both Lortab and Vicodin are potentially addictive because they contain the opioid hydrocodone. With regular use, the body becomes physically dependent, so stopping suddenly causes withdrawal symptoms such as anxiety, restlessness, sweating, muscle aches, and trouble sleeping, which is why they should be tapered rather than stopped abruptly after prolonged use. Beyond physical dependence, the opioid can produce euphoria, giving these medications a potential for misuse and addiction: taking more than prescribed, using them to get high, or taking them without a prescription is misuse and can lead to a substance use disorder. Taken exactly as prescribed for a genuine need and monitored by a doctor, the risk is lower, but it is never zero with an opioid. Signs of a problem include taking more than intended, craving the medication, and continuing despite harm. Opioid addiction is treatable, so anyone whose use has become hard to control should seek help.
Why is the acetaminophen in Lortab and Vicodin a concern?
The acetaminophen (paracetamol) in Lortab and Vicodin is a concern because, while it adds pain relief, taking too much of it can cause severe liver damage, which can be fatal. There is a safe daily limit for acetaminophen, and because each Lortab or Vicodin tablet contains acetaminophen, taking more tablets than prescribed, or taking other medicines that also contain acetaminophen at the same time, can push the total over the safe limit and harm the liver. This is a particular risk when someone misuses the medication by taking extra tablets to get more of the opioid effect, because they also take a dangerous amount of acetaminophen. To stay safe, take only the prescribed dose, avoid alcohol (which adds to liver risk), and check whether other medicines you take contain acetaminophen. If you suspect an acetaminophen overdose, seek medical help immediately, as early treatment is important.
What is the overdose risk with Lortab and Vicodin?
Both Lortab and Vicodin carry a serious overdose risk because of their opioid (hydrocodone) and acetaminophen content. Taking too much hydrocodone can dangerously suppress breathing, which can be fatal, and this risk is greatly increased when the medication is combined with alcohol, benzodiazepines, or other sedatives, a combination involved in many opioid overdose deaths. Separately, too much acetaminophen can cause severe liver damage. A suspected opioid overdose, with very slow or stopped breathing, severe drowsiness, or unresponsiveness, is a medical emergency requiring immediate help and naloxone if available. To reduce the risk, take these medications exactly as prescribed, never combine them with alcohol or other sedatives without medical advice, do not exceed the dose or the safe acetaminophen limit, and store them safely away from others, especially children. Understanding the overdose risk is essential to using these opioid medications safely.
How is addiction to Lortab or Vicodin treated?
Addiction to Lortab or Vicodin is treated as opioid addiction, because the addictive component is the opioid hydrocodone. Treatment often includes medication-assisted treatment with medications such as buprenorphine (as in Suboxone) or methadone, which relieve cravings and withdrawal and dramatically reduce the risk of relapse and overdose, alongside counselling and behavioural therapy that address the patterns and underlying issues driving the use. Because stopping an opioid abruptly causes withdrawal, coming off is managed with a taper or with maintenance medication rather than going cold turkey. For many people, a structured treatment program, outpatient or residential, provides the best foundation by combining medical support, therapy, and a stable environment, with ongoing support afterwards to maintain recovery. The encouraging message is that opioid addiction is very treatable, and effective help is available. If your use of Lortab, Vicodin, or any opioid has become hard to control, seeking help is the first step.
