What this interaction means in plain words
Potassium and Sparsentan can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

What to do
Avoid unneeded potassium supplements or salt substitutes. If necessary, monitor serum potassium frequently and adjust therapy.
