Spravato Side Effects: What's Common, What's Rare, and What to Watch For
Spravato side effects exist, and you deserve an honest accounting of them before you start. The good news is that the common ones are short-lived and predictable, the serious ones are rare, and almost every side effect of Spravato is something we monitor for in real time during your two-hour observation. Here's the full picture, broken down by frequency.
Most common side effects
The most commonly reported side effects in clinical trials and in practice are dissociation (a feeling of detachment), dizziness, nausea, sedation, and a temporary increase in blood pressure. Most of these peak in the first 40 minutes after dosing and resolve substantially by the time you leave the clinic. They are dose-related; they aren't dangerous.
Less common — blood pressure changes
Spravato causes a transient rise in blood pressure that typically peaks around 40 minutes after dosing and returns to baseline by 90 minutes. For most patients this is mild and inconsequential. For patients with uncontrolled hypertension or cardiovascular risk, we adjust the plan — sometimes that means optimizing BP control before starting, sometimes it means a different treatment path. This is one reason we check your vitals at every session.
Rare but serious — what to call about immediately
Severe blood pressure spikes that don't resolve, severe or persistent dissociation beyond a few hours after dosing, suicidal thoughts that worsen rather than improve, signs of an allergic reaction. These are uncommon but not zero. If you're unsure, call. We'd rather hear about a non-issue than miss a real one.
How long side effects typically last
The dissociation, dizziness, and sedation are almost always resolved within two hours — the reason your observation period exists. Nausea usually resolves by the time you leave. A vivid dream that night and slight fatigue the next morning are common; both pass.
How we manage side effects in clinic, in real time
Real-time management is the point of being in the clinic. We check your vitals every 30 minutes, we have anti-nausea medication on hand, we adjust lighting and music, and we can extend your observation if you need extra time. You are not toughing anything out alone.
Side effects you should NOT be told are normal
Worsening depression. New suicidal ideation. Confusion that doesn't clear in two hours. Hallucinations distinct from gentle visual patterns. Severe headache. A clinic dismissing these is not handling Spravato correctly. Bring them up. Push back.
