Neurological Medications 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 Neurological Medications (Neurological Medications). Many supplements are inert or harmless, but a small number — particularly herbal extracts and high-dose vitamins — can affect how Gabapentin, Lamotrigine, Topiramate works at 25mg, 50mg, 100mg, 200mg, 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 Neurological Medications 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 Gabapentin, Lamotrigine, Topiramate, the medication list reviewed by the pharmacist should always include supplements. Most multivitamins at standard doses do not interact meaningfully with Neurological Medications at 25mg, 50mg, 100mg, 200mg, 300mg, but anything herbal, anything single-ingredient at high dose, and anything new started recently is worth flagging.
Frequently asked questions
