Thank you for contacting Holy Hydrogen. Unfortunately, we are not physicians and cannot provide you any medical advice. Please consult with your doctor. However, molecular hydrogen researches suggest that if the hydrogen water is not electrolyzed and pH neutral, and uses no chemical reaction, it should not affect the medication. The important thing to keep in mind is that molecular hydrogen appears to work very well on certain conditions and medication needs to be adjusted accordingly. Again, Please consult with your doctor.
