Rifampin + Sertraline

MODERATE — Monitor Closely

CAUTION — monitor for depression/anxiety breakthrough

Evidence level: MODERATE

What this interaction means

Rifampin may reduce the effectiveness of Zoloft, worsening depression or anxiety.

How it works (mechanism)

Rifampin induces CYP3A4 and CYP2C19. Sertraline is partially metabolized by these enzymes. May reduce sertraline levels.

Practical advice

Monitor mood closely during rifampin therapy. SSRI dose may need adjustment. Inform both prescribers.

Timing

Take Sertraline and Rifampin at their usual prescribed times. Some antibiotics (linezolid especially) have serotonergic properties and should never be combined with SSRIs — if you are on linezolid, confirm this combination with your prescriber. Standard antibiotics like amoxicillin or azithromycin are generally safe alongside SSRIs.

Risk factors

Active depression, recent dose stabilization

Symptoms to watch for

Worsening depression, anxiety, irritability, insomnia

What to tell your doctor

Inform both doctors. Monitor mood closely during TB treatment.

Safer alternatives

Discuss this combination with your prescriber. They may adjust timing, dosing, or switch to an alternative with fewer interaction risks. Never stop an antidepressant abruptly — taper under medical guidance.
