Are there any contraindications to using Cysta-Q?
There is a theoretical risk that use of Cysta-Q will interfere with the action of quinolone antibiotics (eg Cipro, Floxin, Levaquin). Therefore, don’t take these antibiotics with Cysta-Q. It is known that bioflavonoids cross the placenta and in fact are found in higher concentrations in the fetal blood than in the mother’s. Since antioxidants such as Cysta-Q can behave as pro-oxidants at very high doses, harm to the fetus is theoretically possible. Therefore, don’t take Cysta-Q if you are pregnant and use birth control while you are taking the product.
