Does TheraLith XR interact with any prescription medications?
The list below includes some of the more common potential interactions. This is not meant to be a comprehensive list or take the place of advice from your healthcare provider. As with any dietary supplement, discuss with your pharmacist and/or healthcare team to determine whether TheraLith XR can be taken along with your medications.

Antibiotics: Taking magnesium with antibiotics can decrease their absorption and effectiveness. Depending on which antibiotic is prescribed, you may need to separate TheraLith XR from the antibiotic, as indicated below.

  • Quinolone antibiotics (Ciprofloxacin (Cipro), gemifloxacin (Factive), levofloxacin (Levaquin), Moxifloxacin (Avelox)): Separate by 6 hours.
