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

Ubiquinone, also called coenzyme Q10, is a fat-soluble compound the body makes on its own and uses inside mitochondria, where it carries electrons along the respiratory chain that produces cellular energy. It also acts as an antioxidant in cell membranes. It is sold over the counter and is commonly taken for general energy support and as an adjunct in heart failure.
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.
Because the molecule is fat-soluble, it is absorbed poorly on an empty stomach and is taken with a meal that contains some fat. It can interact with warfarin, a vitamin K antagonist: ubiquinone is structurally related to vitamin K and may blunt the anticoagulant effect, so INR is worth watching closely if the two are combined. Anyone on warfarin is best served by telling the doctor or pharmacist before starting it rather than adding it quietly.
Bleeding, unusual bruising, or an INR that drifts out of range after ubiquinone is added calls for a doctor's review. Worsening breathlessness or swelling in heart failure is a matter for the treating physician, not for a supplement adjustment.
