Levofloxacin (Levaquin) and Ketamine Therapy | Tovani Health
Levaquin (Levofloxacin) — Fluoroquinolone antibiotic
Verdict at Tovani Health
Fully compatible; same logic as ciprofloxacin.
Levofloxacin and ketamine have no clinically significant interaction. Same compatibility profile as ciprofloxacin. The fluoroquinolone-specific cautions (QT prolongation, tendon rupture, peripheral neuropathy in rare cases) are intrinsic to the drug class and independent of KAP; ketamine itself is not a meaningful QT-prolonging drug at psychiatric doses.
If you take Levaquin regularly and are considering at-home ketamine therapy, the combination is generally safe at therapeutic doses. This page covers the brief pharmacologic context and what we do at intake.
How Levaquin interacts with ketamine

What we do at intake
Continue your course as prescribed.
Bottom line
Levofloxacin and ketamine have no clinically significant interaction. Same compatibility profile as ciprofloxacin. The fluoroquinolone-specific cautions (QT prolongation, tendon rupture, peripheral neuropathy in rare cases) are intrinsic to the drug class and independent of KAP; ketamine itself is not a meaningful QT-prolonging drug at psychiatric doses.
