Cyclogest is not indicated in threatened miscarriage. Treatment should be discontinued in the event of a missed miscarriage.
Cyclogest should be discontinued if any of the following conditions are suspected:
myocardial infarction, cerebrovascular disorders, arterial or venous thromboembolism (venous thromboembolism or pulmonary embolism), thrombophlebitis or retinal thrombosis.
Although risk of thromboembolism has been associated with estrogens, a link with progestins remains questionable. Therefore, in women with generally recognised risk factors for thromboembolic events, such as personal or family history, treatment with Cyclogest may further increase the risk. In these women, the benefits of Cyclogest administration need to be weighed against the risks. It should be noted however, that pregnancy itself carries an increased risk of thrombo-embolic events.
Patients with a history of depression need to be closely observed. Consider discontinuation if symptoms worsen.
Because progesterone may cause some degree of fluid retention, conditions that might be influenced by this factor (e.g. epilepsy, migraine, asthma, cardiac or renal dysfunction) require careful observation.
A decrease in glucose tolerance has been observed in a small number of patients on estrogen- progestin combination drugs. The mechanism of this decrease is not known. For this reason, diabetic patients should be carefully observed while receiving progestin therapy.
Progesterone is metabolised in the liver and should be used with caution in patients with hepatic dysfunction.
Cyclogest contains the hormone progesterone which is present in significant concentrations in women during the second half of the menstrual cycle and during pregnancy. This should be borne in mind when treating patients with conditions that may be hormone-sensitive.
Abrupt discontinuation of progesterone dosing may cause increased anxiety, moodiness, and increased sensibility to seizures.
Use rectally if barrier methods of contraception are used.
Use rectally if patients suffer from vaginal infection (especially moniliasis) or recurrent cystitis or have recently given birth.
Use vaginally if patients suffer from colitis or faecal incontinence.
