Due to possible impairment of absorption, OZOVIT™ and the following drugs should generally be taken 1 to 2 hours apart from each other: iron, tetracyclines, sodium fluoride, isoniazid, chlorpromazine, and digoxin.
As with other laxatives, prolonged use of OZOVIT™ may be associated with increased loss of water, potassium, and other salts. This may cause disorders of heart function and muscle weakness.
Therefore this product should not be used for longer than a week.
