Capsule shells and tablet coatings in Mirtazapine
The most common animal-derived component in any oral medication is gelatin, used in the shell of soft and hard capsules and extracted from bovine or porcine tissue. According to the Mirtazapine prescribing information, the available dosage forms are tablet — gelatin capsules should be assumed non-vegan unless the manufacturer specifies an HPMC (hypromellose, plant-derived) shell. Tablet film coatings are usually plant-based; enteric coatings on a small subset of products can use shellac, an insect-derived resin. Pharmacy staff can confirm which formulation of Mirtazapine at the 7.5mg, 15mg, 30mg, 45mg strengths uses gelatin and which does not.
Common excipients of animal origin
Beyond the capsule, several excipients have potential animal-origin variants. Lactose monohydrate, present in many tablets, is dairy-derived. Magnesium stearate and stearic acid can be sourced from animal or vegetable fat — modern pharmaceutical manufacturing typically uses vegetable, but the prescribing information rarely states the source. Cochineal (E120) is a possible colourant of insect origin. The full excipient list for Mirtazapine (Mirtazapine) is published with the Atypical antidepressant (NaSSA) class label; people following strict diets are encouraged to review it for each new prescription, as generic manufacturers can vary in their formulations and excipient choices.
