Dihydrocodeine products which can be purchased over the counter in many European and Pacific Rim countries generally contain from 2 to 20&nbsp;mg of dihydrocodeine per dosing unit combined with one or more other active ingredients such as paracetamol (acetaminophen), aspirin, ibuprofen, antihistamines, decongestants, vitamins, medicinal herb preparations, and other such ingredients.  In a subset of these countries and foreign possessions, 30&nbsp;mg tablets and 60&nbsp;mg controlled-release tablets are available over the counter and chemists may very well be able to dispense the 90 and 120&nbsp;mg strengths at their discretion.

In the United States, the most common analgesic brands with dihydrocodeine are: DHC Plus (16 and 32&nbsp;mg), Panlor SS (32&nbsp;mg), ZerLor (32&nbsp;mg), Panlor DC (16&nbsp;mg) and Synalgos DC (16&nbsp;mg).  These combination products also include paracetamol (acetaminophen) and [[caffeine]].  Aspirin is used in the case of Synalgos DC.

Dihydrocodeine is sometimes marketed in combination preparations with paracetamol as [[co-dydramol]] ([[British Approved Name|BAN]]) to provide greater pain relief than either agent used singly (see [[Synergy#Drug synergy|Synergy § Drug synergy]]).

In the UK and other countries, 30&nbsp;mg tablets containing only dihydrocodeine as the active ingredient are available, also a 40&nbsp;mg Dihydrocodeine tablet is available in the UK as DF-118 Forte.

The original dihydrocodeine product, Paracodin, is an elixir of dihydrocodeine hydroiodide also available as a Tussionex-style suspension in many European countries.

In many European countries and elsewhere in the world, the most commonly found dihydrocodeine preparations are extended-release tablets made by encasing granules of the ingredient mixture, almost always using the bitartrate salt of dihydrocodeine, of four different sizes in a wax-based binder.  The usual strengths are 60, 90, and 120&nbsp;mg.  Common trade names for the extended-release tablets are Didor Continus, Codidol, Codi-Contin, Dicodin (made in France and the major product containing the tartrate salt), Contugesic, DHC, and DHC Continus.

Dihydrocodeine is available in Japan as tablets which contain 2.5&nbsp;mg of dihydrocodeine phosphate and caffeine, the decongestant [[N-Methylephedrine|d,l-methylephedrine HCl]], and the antihistamine [[chlorpheniramine]], and packets of granules which effervesce like Alka-Seltzer with 10&nbsp;mg of dihydrocodeine with [[lysozyme]] and chlorpheniramine, marketed for OTC sale as New Bron Solution-ACE.  These two formulations may have once contained [[phenyltoloxamine]] citrate as the antihistamine component.

Elsewhere in the Pacific Rim, Dicogesic in analogous to Glaxo/Smith-Kline's DF-118.
