Collagen peptides
Prescription status is set country by country — the label where you live is the one that applies.

Collagen peptides are short chains of amino acids made by breaking down animal collagen into fragments small enough to be absorbed from the gut. Once absorbed, they enter the body's general amino acid pool and supply the building blocks, notably glycine and proline, that connective tissue draws on. They are taken as a food supplement in the context of joint and skin support.
A usual adult range, not a national label — the dose and the timing differ by country and by product.
Approved uses differ by country — some of these may be off-label or unapproved where you live.
Timing is flexible: the peptides can be taken with a meal or between meals, and no particular food is needed for absorption. The amino acid profile is unbalanced and low in the essential amino acids, so collagen does not count as a complete protein source and should not displace ordinary dietary protein. It is a supplement rather than a treatment, and any effect builds slowly over weeks rather than being felt immediately.
Joint pain that is new, worsening, one-sided, or comes with swelling, redness or fever is not something a supplement addresses, and warrants seeing a doctor rather than continuing to wait it out.
