The recommended dosage is 150 mg of Andalan every three months by deep intramuscular injection. In order to ensure that the acceptor is not pregnant, the first, injection is administered during the first 5 days of normal menstrual period or before the 6th week postpartum. Andalan does not interfere with lactation. Even though Medroxyprogesterone Acetate is secreted in breast milk in very small amounts, as of present, there have not been any side effects reported on a baby's growth. It is suggested that the physician or others directly responsible for the patient informs the patient that at the beginning of treatment, that there will be changes to the menstrual cycle and unpredictable bleeding or spotting may occur. The symptoms will decrease if the usage of Andalan is continued, without the need of additional treatments. Excessive or prolonged bleeding which becomes troublesome to the acceptor can be controlled by giving estrogen with the dosage equal to 0.05-0.1 mg ethinyl estradiol daily for 7-12 days, orally or parenterally. This treatment can be continued for 1-2 cycles but is not suggested for long term usage.
