Dolo-Neurobion vs. Neurobion: What's in Each and How They Differ
Share
Dolo-Neurobion and Neurobion share a name, but they're very different products. One is an over-the-counter pain reliever and the other is a line of B-vitamin supplements. On top of that, the Dolo-Neurobion sold in the US has a different active ingredient than the one sold in Mexico. Here's how they compare.
What's in Dolo-Neurobion in the US
Dolo-Neurobion Extra Strength in the US is an over-the-counter (OTC) drug with one active ingredient:
- Acetaminophen 500 mg per tablet (also known as paracetamol).
- Purpose, per its Drug Facts label: pain reliever and fever reducer.
Its label says it temporarily relieves minor aches and pains due to headache, muscular aches, backache, toothache, minor arthritis pain, the common cold, and menstrual cramps, and temporarily reduces fever.
There's also Dolo-Neurobion Max, with 650 mg of acetaminophen per extended-release caplet.
Dolo-Neurobion from Mexico has a different ingredient
In Mexico, Dolo-Neurobion is a prescription drug from another company that combines diclofenac (a nonsteroidal anti-inflammatory drug) with vitamins B1, B6, and B12. So when someone searches "what's in Dolo-Neurobion" or "Dolo-Neurobion 500 mg," the answer depends on where the box came from.
| Dolo-Neurobion (US) | Dolo-Neurobion (Mexico) | |
|---|---|---|
| Active ingredient | Acetaminophen | Diclofenac + B vitamins |
| Type | OTC drug | Prescription drug |
| Brand owner | OTC Pharmaceutical Products | A different pharmaceutical company |
Is Dolo-Neurobion a painkiller?
Yes. The US version is a pain reliever and fever reducer made with acetaminophen. It doesn't contain B vitamins. If you're after a B-vitamin supplement, you want a product from the Neurobion line, like Neurobion Classic or Neurobion B12 Forte.
Key acetaminophen warnings
Dolo-Neurobion's Drug Facts label includes a liver warning: severe liver damage may occur if you take more than 4,000 mg of acetaminophen in 24 hours, take it with other drugs containing acetaminophen, or have 3 or more alcoholic drinks every day while using it. Also:
- Check whether your other medications (cold and flu products, cough syrups, nighttime pain relievers) also contain acetaminophen.
- Ask a doctor before use if you have liver disease.
- Ask a doctor or pharmacist if you take the blood thinner warfarin.
- Stop use and ask a doctor if pain gets worse or lasts more than 10 days.
- Always read and follow the label.
Neurobion: the vitamin line
In the US, the Neurobion line is made up of B-complex dietary supplements in tablets, syrup, and drinkable vials. The most searched ones are:
- Neurobion Classic: B1, B6, and B12 in tablets.
- Neurobion B12 Forte: 3,000 mcg of B12 (methylcobalamin) in vials.
- Neurobion B12 Complex liquid: citrus-flavored B-complex syrup.
