Adding topiramate to lithium.

Infobord.png General information
  • Lithium is eliminated by the kidney for about 95%. Changes in the rate of excretion can cause unwanted effects.
  • Topiramate induces CYP3A4 and is an inhibitor of CYP2C19.
  • This combination of drugs may have possible synergistic effects. However, this combination will also have additive side effects. Dose adaptation will be recommended for this combination.
Eenrichtingbord.png Start topiramate
  • Start topiramate according to the general dosing advice.
Letopbord.png Cave
  • Elevated and toxic lithium levels have been reported with higher (800 mg/d) doses of topiramate, but not with 500 mg/d. [2] [3]
  • Pharmacologic response and serum lithium levels should be monitored closely in particular after change of dosage or discontinuation of topiramate.[4]
