Summary
Cobicistat inhibits CYP2D6 and CYP3A4, both involved in clomipramine metabolism, so clomipramine and its active metabolite levels may rise. This can increase the risk of anticholinergic effects, seizures, serotonergic effects and QT prolongation.
What this interaction means in plain words
Clomipramine and Elvitegravir / cobicistat / emtricitabine / tenofovir df can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Inhibition of CYP2D6 and CYP3A4 by cobicistat reduces clearance of clomipramine.
What to do
Start clomipramine at a low dose and titrate according to response and tolerability. Monitor for toxicity and consider an ECG or plasma levels in high-risk patients.
