Armodavinil vs Artvigil: Which 150 mg Armodafinil Should You Pick?

Written by Dr. Marcus Bennett · Medically reviewed by Dr. Elena Marquez, MD · Fact-checked November 2026 · How we review

Armodavinil and Artvigil sit next to each other in a lot of online carts. Both are 150 mg armodafinil tablets made in India, both are sold by export vendors such as Afinil, and both are marketed as cheaper versions of Nuvigil. If you're trying to decide between them, the real differences are the maker, the price per tablet, how much buyer feedback exists and how carefully each product page is written.

Where our numbers come from: we read Afinil's listings for both tablets on October 31, 2026 and checked them against the FDA prescribing information for Nuvigil. Nobody on our team swallowed, tested or sent either product to a lab, so treat this as a buyer's comparison rather than a clinical one. Nothing here replaces your prescriber, who should be the one deciding whether armodafinil is right for you and how much to take. Buying through our Afinil links can earn us a commission; your price stays the same.

Armodavinil vs Artvigil at a glance

• Same drug, same strength: both pages list 150 mg armodafinil per tablet, with Nuvigil named as the reference brand.
• Different makers: Centurion Laboratories for Armodavinil and HAB Pharma for Artvigil, according to Afinil.
• Cost: HAB's tablet undercut Centurion's on every option in the dropdown: a quarter less on the smallest pack, roughly 15% less on 100 and close to 38% less on 500.
• Pack sizes: both run from 10 to 1,000 tablets.
• Feedback: 15 reviews for Artvigil (4.7 out of 5) against 5 for Armodavinil (4.8 out of 5).

Short version: Artvigil wins on value for most people, and Armodavinil only makes sense if Centurion's tablet specifically appeals to you.

Who makes each tablet

Armodavinil 150 mg is listed by Afinil as a Centurion Laboratories product. Centurion also makes Modavinil (modafinil) and Vilafinil, and Afinil sells Modavinil and Armodavinil together in a Centurion combo pack. Afinil presents Armodavinil as a newer brand that it says was introduced to replace Waklert, which the page claims "will no longer be available in the USA and other countries due to legal issues". We couldn't confirm that claim, and Afinil still sells Waklert. Our Armodavinil 150 mg review covers what we could and couldn't verify about the brand itself.

Artvigil 150 mg comes from HAB Pharma, which Afinil says has made generic and specialty drugs since 1980. It's one of the best-known armodafinil names on the export market, usually mentioned alongside Modvigil, HAB's modafinil. For a closer look at the company, see our HAB Pharmaceuticals review; for the tablet on its own, see our Artvigil 150 review.

You won't find either brand at a US pharmacy counter. The armodafinil the FDA has approved is Nuvigil plus the US generics made under that approval; Armodavinil and Artvigil are Indian export brands outside that system.

Price per tablet, pack by pack

Below is each tablet's unit price from Afinil's quantity dropdown on October 31, 2026. Vendors adjust prices often, so confirm the figure in your cart before paying.

What that means in dollars

Multiplying those unit prices out (no shipping, no crypto discount) gives these order totals:

• 30 tablets: Armodavinil about $90, Artvigil about $78. Difference: about $12.
• 100 tablets: Armodavinil about $199, Artvigil about $169. Difference: about $30.
• 500 tablets: Armodavinil about $795, Artvigil about $495. Difference: about $300.
• 1,000 tablets: Armodavinil about $1,090, Artvigil about $890. Difference: about $200.

One odd detail stands out. Armodavinil's 1,000-tablet price ($1.09 each) is far below its 500-tablet price ($1.59), so its biggest pack closes much of the gap with Artvigil. At every other size the difference is meaningful, and on a 500-tablet order it's the largest.

Both tablets come from the same shop, so delivery terms match. Afinil's site-wide banner promises free shipping above $130, and the Artvigil listing mentions free Express Mail Service from $180 with an estimate of 7 to 12 business days. Small orders, such as 30 tablets of either brand, sit below both lines, so factor in postage. The store's 24% Bitcoin discount applies to both brands equally and doesn't change the ranking.

Reviews and track record

Artvigil's listing carried 15 ratings averaging 4.7 stars; Armodavinil's had just 5, averaging 4.8. Neither number is large enough to mean much, and both sit on the seller's own site. Afinil credits Yotpo with verifying them, which helps confirm a purchase happened but says nothing about whether your batch will suit you.

Track record is where Artvigil has a clear edge. It has been sold online for years and there's a lot of independent discussion about it. Armodavinil is newer and far less discussed. That doesn't make it worse; it just means there's less outside experience to go on if you want to know what to expect.

Claims on the product pages that don't hold up

Both product pages contain lines a careful buyer should read with skepticism. We've listed the ones that matter most.

1. "This drug has approval from the Food and Drug Administration." The Artvigil page says this. It isn't accurate for Artvigil. The FDA approved armodafinil as a drug, under the Nuvigil brand and its US generics. Artvigil itself is not an FDA-approved product.
2. Effects lasting "about 71.5 hours (close to 3 days)." The Armodavinil page says this while also giving a half-life of about 13 hours. The two statements don't fit together. The Nuvigil label gives a half-life of about 15 hours, and the drug is meant to be taken once a day in the morning or before a shift.
3. "No prescription? No problem!" The Armodavinil page ends its sales pitch with this. In the US that's simply wrong: armodafinil is a Schedule IV controlled substance that requires a valid prescription.
4. Weight loss as a benefit. The Artvigil page presents weight loss as a plus for overweight users. Decreased appetite is a listed side effect of armodafinil, not an approved use, and it isn't a reason to take the drug.
5. Productivity marketing. Both listings sell the tablets as tools for students, entrepreneurs and long workdays. That's off-label. The only uses on the US Nuvigil label are for adults who are excessively sleepy because of narcolepsy, obstructive sleep apnea or shift work disorder.

None of this tells you the tablets themselves are bad. It does tell you to treat the marketing text as marketing, and to rely on the label for how the drug actually works.

What the Nuvigil label says about armodafinil

Because both brands contain the same drug at the same dose, the label facts apply equally to each:

• What it's approved for: keeping adults awake when narcolepsy, obstructive sleep apnea or shift work disorder causes excessive sleepiness.
• Usual dose: 150 mg or 250 mg once a day in the morning for sleep apnea and narcolepsy; 150 mg about an hour before the shift for shift work disorder. The label notes that doses above 150 mg haven't shown consistent extra benefit in sleep apnea.
• Timing: peak blood levels about 2 hours after a fasting dose. Taking it with food can delay the peak by 2 to 4 hours.
• Half-life: about 15 hours. Steady state is reached in about 7 days of daily use.

This is why we don't expect either brand to "last longer" or "kick in faster" than the other. If you notice a difference after switching, it's more likely to come from sleep, food, timing or expectation than from the brand name. If it's a big difference, talk to your prescriber rather than adjusting the dose yourself. Our guide on how long armodafinil lasts goes into the timing in more detail.

Which one should you pick?

Pick Artvigil 150 if:

• You want the lower unit price, which HAB offered on every quantity.
• Three times the ratings and years of outside discussion reassure you.
• You're buying a mid-size pack (100 to 500 tablets), where the savings are largest.

Pick Armodavinil 150 if:

• You already take Centurion's Modavinil and want armodafinil from the same maker.
• You'd like to try a maker other than HAB, for example because you didn't get on with Artvigil's fillers or coating.
• You're buying the 1,000-tablet pack, where the price gap narrows to $0.20 a tablet.

If you're comparing more than two armodafinil brands, our ArmodaXL vs Armodavinil and Artvigil vs Waklert comparisons cover the other common options, and our best armodafinil brand roundup ranks them side by side.

If you also use modafinil

Plenty of buyers keep both drugs on hand, so it helps to know how each brand fits into a maker "family".

• Centurion family: Armodavinil pairs with Modavinil 200 mg, Centurion's modafinil. Afinil sells the two together as a premium combo pack, so check whether the bundle price actually beats buying each strip on its own before you add it to your cart.
• HAB family: Artvigil pairs with Modvigil 200 mg, HAB's modafinil. Afinil's budget combo puts them in one order, and our Modvigil and Artvigil budget combo review walks through what you get.

Sticking with one maker for both drugs isn't medically necessary, but some buyers like it because the packaging, strips and batch labels look the same and are easier to keep track of. On price, the HAB pairing was the cheaper of the two at the time we checked, which matches the single-brand comparison above.

Keep in mind that modafinil and armodafinil are closely related drugs and are not meant to be taken together. If your prescriber has you on one, don't add the other on your own.

What to check when the order arrives

Whichever brand you choose, a few quick checks are worth the minute they take:

1. Read the strip. The maker's name and the batch number should be printed on the foil. Check it matches the brand you ordered.
2. Check the expiry date. Make sure it's well in the future, especially if you bought a large pack.
3. Keep tablets in their original foil. That keeps them away from moisture and lets you trace the batch later if something seems off.
4. Note anything unusual. Broken tablets, damaged strips or a different-looking product are worth raising with the seller before you take anything.

Switching between the two

Because the molecule and the milligrams stay the same, prescribers generally see a move between these two brands as a straight swap. If yours is on board, these habits keep it simple:

1. Take it at your normal time and at your normal dose.
2. Don't mix brands on the same day.
3. Watch how you sleep during the first week. Armodafinil can affect sleep if taken late.
4. Keep a short note of how you feel so you can tell your prescriber whether the change made a difference.

Legal notes for US buyers

Under US law armodafinil is a Schedule IV drug, so you need a valid prescription from a licensed prescriber, and that prescription can be refilled no more than five times within six months. Armodavinil and Artvigil are manufactured in India and have never been approved by the FDA. Ordering a controlled drug from abroad without a prescription is not a lawful workaround, and customs officers can hold or destroy the parcel. Phrases like "OTC" or "no prescription needed" on a vendor's page carry no legal weight here.

With a prescription in hand, any US pharmacy can dispense FDA-approved generic armodafinil; see our armodafinil price guide for typical costs and our explainer on whether buying modafinil is legal, whose rules cover armodafinil as well.

Armodafinil can cause side effects, including headache, nausea, dizziness and trouble sleeping, and rare but serious skin and allergic reactions. It isn't right for everyone. Talk to a licensed doctor or pharmacist before starting, switching or stopping it.

Verdict

Chemically these are the same product: 150 mg of armodafinil. What separates them is cost, manufacturer and the depth of buyer history. On Afinil's October 31, 2026 prices, HAB's Artvigil saved roughly $30 per 100 tablets and $300 per 500, and it had three times the ratings, so it's our default recommendation. Centurion's Armodavinil is reasonable if you want that maker in particular, and at the 1,000-pack its premium shrinks to 20 cents a tablet. Either way, ignore the sales copy, check the foil when the parcel lands, and keep in mind that a US prescription is required.

FAQ

Is Armodavinil the same as Artvigil?

Both are listed as 150 mg armodafinil tablets, the same active drug and strength as generic Nuvigil, so they are meant to work the same way. They come from different makers: Afinil names Centurion Laboratories for Armodavinil and HAB Pharma for Artvigil. Fillers, coating and batch history can differ.

Which is cheaper, Armodavinil or Artvigil?

Artvigil, at every pack size we checked on October 31, 2026. At 100 tablets Afinil listed Armodavinil at $1.99 each and Artvigil at $1.69; at 500 tablets it was $1.59 vs $0.99; at 1,000 tablets $1.09 vs $0.89.

Is Armodavinil stronger than Artvigil?

There's no evidence of that. Both are labelled 150 mg armodafinil, and we found no study comparing the two brands. Reports that one feels stronger usually come down to sleep, timing, food, expectations or batch.

Is Artvigil FDA-approved?

No. Afinil's Artvigil page says the drug "has approval from the FDA", but that's misleading. The FDA approved Nuvigil and its US generics. Artvigil is an Indian brand that isn't FDA-approved and isn't sold in US pharmacies. The same is true of Armodavinil.

Does Armodavinil last close to three days?

No. Afinil's Armodavinil page says its effects can last about 71.5 hours, but the US Nuvigil label puts armodafinil's half-life at about 15 hours, with peak levels about 2 hours after a dose. Most people feel it through the day, not for three days.

Can I switch from Artvigil to Armodavinil?

They contain the same drug at the same strength, so many people treat them as interchangeable. Still, tell your prescriber and pharmacist about any brand change and pay attention to how you feel on the new one, especially your sleep.

Do I need a prescription for either brand in the US?

Yes. Armodafinil is a Schedule IV controlled substance and needs a valid prescription. Neither brand is FDA-approved, and the "no prescription" wording on vendor pages doesn't change US law.

Which one should I buy?

If price and review history matter most, Artvigil is the clear value pick. Armodavinil makes sense if you specifically want a Centurion tablet, for example because Modavinil already suits you or you didn't get on with HAB's tablets.
