Mixing Ketamine and SSRIs

Mixing Ketamine and SSRIs is relatively low-risk, with roughly additive effects — TripSit rates this combination “Low Risk & No Synergy.” Low risk never means safe.

Ketamine (also known as K, special K) and SSRIs (also known as most antidepressants).

What to do

• Even for lower-risk pairs, the safest choice is not to mix — and never to use alone.
• Start with much less than usual and go slow — you can always take more, never less.
• Never use alone. If you do, call 1-800-484-3731 (Never Use Alone) so someone can send help if you stop responding.
