Magnesium and SSRI: interaction risk (minor)
Severity minor. Generally fine with an SSRI; space about 2 hours apart. No credible harm signal in the sources we track — this is a "no known interaction" record, not a proven-safe verdict.
Severity: minor
- minorMagnesium + SSRI: Generally fine with an SSRI; space about 2 hours apart.
How serious is this?
Severity minor means: weak or theoretical signal; case reports and pharmacokinetic reasoning suggest a small risk that most people will not experience.
Mechanism
Interaction type: neutral. Mechanism-specific detail is thin in the source data — treat as a signal to consult a pharmacist rather than a fully-characterised interaction.
Does this apply to other selective serotonin reuptake inhibitor drugs?
No other selective serotonin reuptake inhibitor drugs modeled yet. When mechanism is receptor- or enzyme-based, treat class members as probably-similar until data proves otherwise.
Spacing & timing
Studied separation: ~2h. Applies when the mechanism is chelation- or absorption-based.
Why "no known" is not the same as "safe"
We searched the interaction corpus for Magnesium with SSRI. Depth of evidence: case-report level and below. This page is the honest record of what has and has not been reported — a calm baseline, not a green light. Update triggers: new FDA/EMA communications, new pharmacokinetic studies, credible case reports.

Frequently asked
Can I take Magnesium and SSRI together?
Severity is the shorthand; the mechanism and studied evidence matter. Read the severity block and the mechanism block — combined they answer this in a way a single yes/no can't.
What if I already took Magnesium with SSRI?
If symptoms appeared, contact your pharmacist or Poison Control. If nothing happened and severity is low, note it and avoid habitual co-use without a pharmacist's OK.
How far apart should I space Magnesium and SSRI?
Only meaningful when the interaction is chelation- or absorption-based and studied. If the mechanism is pharmacodynamic (additive sedation, serotonergic load), spacing does not fix it.
Does the Magnesium + SSRI interaction apply to other drugs in the same class?
Interactions are usually class-wide when the mechanism is at the receptor/enzyme, not the specific molecule. The mechanism block above tells you which case this is.
Should I tell my doctor I take Magnesium?
Yes — pharmacists especially. The single most useful thing you can do about supplement interactions is put them on your medication list.
