Yes, you can use Pregabalin together with supplements such as Mastika, Milk Thistle, and vitamins A and D, as there are no direct interactions between Pregabalin and these preparations.

Milk thistle has hepatoprotective and anti-inflammatory effects, but it can affect the metabolism of some drugs, especially antidiabetic and anticoagulants, so it is worth being careful and informing your doctor about its use. Mastika is not listed as a substance that interacts with Pregabalin. Supplementation with vitamins A and D is usually safe, as long as it does not exceed the recommended doses. I encourage you to consult your doctor before starting concomitant supplementation to take into account individual health factors and avoid possible adverse effects.
