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 are modeled. This record is not generalized to unreviewed class members.
Spacing & timing
Studied separation: ~2h. Applies when the mechanism is chelation- or absorption-based.
Why "no known" is not the same as "safe"
No adjudicated interaction edge is recorded for Magnesium with SSRI in the current modeled set. That is an unassessed coverage state, not proof that a comprehensive literature search found no risk.

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.
