Can Magnesium Glycinate Be Taken With Veozah (Fezolinetant)?
Yes, magnesium glycinate can be taken with Veozah without separating doses, as there are no documented drug interactions between these medications.
Key Points
The FDA-approved prescribing information for Veozah does not list magnesium supplements as contraindicated or requiring dose separation 1. Veozah is contraindicated only with CYP1A2 inhibitors, in patients with cirrhosis, and in those with severe renal impairment 1.
Dosing Recommendations
Veozah Administration
- Dose: 45 mg tablet once daily
- Timing: Take at approximately the same time each day
- Food: Can be taken with or without food
- Administration: Swallow whole with liquids; do not cut, crush, or chew 1
Magnesium Glycinate Considerations
While no specific interaction exists with Veozah, general magnesium supplementation guidance suggests:
- Start at recommended daily allowance (350 mg for women, 420 mg for men)
- Increase gradually according to tolerance 2
- Liquid or dissolvable forms are better tolerated than pills 2
- Watch for gastrointestinal side effects (diarrhea, nausea) with higher doses 2
Critical Monitoring Requirements for Veozah
Mandatory hepatic monitoring is required 1:
- Baseline: ALT, AST, alkaline phosphatase, total and direct bilirubin before starting
- Do not start if ALT or AST ≥2× ULN or total bilirubin ≥2× ULN
- Follow-up testing: Monthly for first 3 months, then at 6 and 9 months
- Discontinue immediately if signs of liver injury develop (fatigue, decreased appetite, nausea, vomiting, jaundice, dark urine, pale stools, abdominal pain)
Additional Monitoring
Regular monitoring of serum calcium, electrolytes, phosphate, magnesium, and hemoglobin/hematocrit is recommended when using medications that affect mineral metabolism, though specific intervals are not evidence-based 3.
Important Caveats
- Renal function: If the patient has renal impairment, magnesium supplementation requires caution as magnesium is renally excreted. Avoid in severe renal impairment (creatinine clearance <20 mL/dL) 4
- Veozah contraindication: Veozah itself is contraindicated in severe renal impairment or end-stage renal disease 1
- No dose separation needed: Unlike some medications that require separation from magnesium (certain antibiotics, bisphosphonates), Veozah has no such requirement
Note on Medication Confusion
The question mentions "budesonide/formoterol (Veozah)" which appears to be an error. Veozah is fezolinetant, a neurokinin 3 receptor antagonist for menopausal vasomotor symptoms 1. Budesonide/formoterol is a completely different medication—an inhaled corticosteroid/long-acting beta-agonist combination used for asthma and COPD 5, 6, 7. If the patient is actually taking budesonide/formoterol, there are similarly no documented interactions with magnesium glycinate requiring dose separation.
