Are fluoxetine and priadel are suitable for vegans/vegetarians?

Fluoxetine is an: antidepressant and priadel (lithium) is a mood stabilizer. Being a vegan/vegetarian should have no impact. You will need to have some salt intake with lithium. Ensure intake of protein (legumes, lentils, nuts, seeds, whole grains, and soy but take it easy on amount of soy), omega-3 fatty acids, B12, calcium, vitamin D, zinc, and iron sources within your diet. Avoid junk. Best regards!

Sure: Not sure if you're asking whether the manufacturers include ingredients to which a vegan might object. The health benefits of appropriately prescribed meds for the conditions these meds treat far outweigh any health benefits you might derive from being a vegan.
