Norepinephrine-dopamine reuptake inhibitor (NDRI) antidepressant
Bupropion with vitamins, minerals and herbal supplements
Supplements are widely used and rarely disclosed to the prescriber, which makes them a common source of unrecognised interactions with Bupropion (Bupropion). Many supplements are inert or harmless, but a small number — particularly herbal extracts and high-dose vitamins — can affect how Bupropion works at 75mg, 100mg, 150mg, 300mg.
High-priority supplement interactions
St John's Wort is the herbal supplement most often flagged for interactions because it strongly induces CYP3A4 and reduces plasma levels of many medications including several Norepinephrine-dopamine reuptake inhibitor (NDRI) antidepressant agents. Grapefruit-extract supplements work in the opposite direction. High-dose vitamin K affects anticoagulants. Calcium and iron can chelate certain antibiotics.
Practical disclosure
According to the prescribing information for Bupropion, the medication list reviewed by the pharmacist should always include supplements. Most multivitamins at standard doses do not interact meaningfully with Bupropion at 75mg, 100mg, 150mg, 300mg, but anything herbal, anything single-ingredient at high dose, and anything new started recently is worth flagging.
Frequently asked questions
Are vitamins safe with Bupropion? ▾
Standard-dose multivitamins are usually fine with Bupropion at 75mg, 100mg, 150mg, 300mg. High-dose single vitamins (e.g. vitamin K, large doses of vitamin E) can interact with specific medication classes; the pharmacist confirms whether these matter for Bupropion.
Should I tell the pharmacist about herbal supplements? ▾
Yes — particularly St John's Wort, ginseng, ginkgo, garlic extract and any concentrated herbal formulation. Several of these have meaningful interactions with prescription medications including some agents in the Norepinephrine-dopamine reuptake inhibitor (NDRI) antidepressant class.
