It looks like your message is incomplete. If you mean “Never use magnesium if you are taking any of the following medications…”, please send the rest of the list or the full text, and I can help explain it.
In general, magnesium supplements can interact with some medicines by reducing absorption or changing effects. Common examples that may require spacing doses or medical advice include:
- Certain antibiotics (especially tetracyclines and fluoroquinolones)
- Thyroid hormone replacement (such as levothyroxine)
- Some osteoporosis medicines (bisphosphonates)
- Certain diuretics or heart/kidney-related medicines (depending on the situation)
The exact advice depends on the type of magnesium, dose, and the specific medication(s) involved.
