I would just not have her take the MMS the same time as the med. Using DMSO with MMS: Would be good, the DMSO carries the activated MMS deeper into the tissues - helps break up blood clots. The MMS will also help clean out the arteries, which in effect (in my opinion) will thin the blood. If it was me, I would be sure that they are checking her blood, and maybe would need to reduce the blood thinner. As Jim say, she also should take Vit C to help protect and strengthen the blood vessel walls (take Vit C at least 2 hrs after dosing ends).
