Can i take advil (ibuprofen) with lithium?

Carefully: Advil (ibuprofen) may increase lithium blood levels by reducing the excretion of lithium by the kidneys. This could lead to lithium toxicity. One study that tested high-dose (1800 mg/day) Ibuprofen said "lithium dosage may need to be reduced in some patients following initiation of Ibuprofen therapy." the effect may be less at low doses or if advil is used rarely. Consult with your prescriber.

Advil/Lithium: If excess advil, (ibuprofen) can raise lithium level. Use with caution & only as needed.
