This product is intended for use in combination with an oestrogen product. The prescribing information for the oestrogen product should be consulted for additional precautions and warnings.
Assessment of each woman before taking hormone replacement therapy (and at regular intervals thereafter) should include a personal and family medical history. Physical examination should be guided by this and a knowledge of the contraindications and precautions and warnings for use of the product. Clinical examination of the breasts and pelvic examination should be performed where clinically indicated rather than as a routine procedure. Patients should be encouraged to report any changes in their breasts to their doctor or nurse. Investigations including mammography should be carried out in accordance with currently accepted screening practices, modified according to the clinical needs of the individual.
Discontinue treatment and initiate appropriate diagnostic and therapeutic measure in the event of any deterioration in vision, proptosis, migraine, diplopia, papilloedema or retinal vascular lesions.
Pregnancy and Lactation
Contraindicated during pregnancy.
Exclude pregnancy prior to initiating therapy with progesterone.
Discontinue immediately if pregnancy occurs during treatment.
Development alterations in the psychosexual performance of boys have been attributed to exposure to estradiol and progestogen in the womb. Males who have been exposed to estradiol and progestogen have demonstrated a trend to have less heterosexual characteristics and fewer masculine interests than males which have not been exposed to these hormones prenatally.
The use of all medication in pregnancy should be avoided whenever possible; particularly in the first trimester. Non-drug treatments should also be considered. When essential, a medication with the best safety record over time should be chosen, employing the lowest effective dose for the shortest possible time. Polypharmacy should be avoided. Teratogens taken in the pre-embryonic period, often quoted as lasting until 14-17 days post-conception, are believed to have an all-or-nothing effect. Where drugs have a short half-life, and when the date of conception is certain, this may allow women to be reassured where drug exposure has occurred within this time frame. Further advice may be available from the UK National Teratology Information Service (NTIS) and through ToxBase, available via password on the internet ( www.toxbase.org ) or if this is unavailable at the backup site ( www.toxbasebackup.org ).
Not indicated for use in breastfeeding women.
Progesterone is secreted in breast milk.
Neonates, infants born prematurely, those with low birth weight, those with an unstable gastrointestinal function or who have serious illnesses may require special consideration. For any infant, if a drug is prescribed to the nursing mother, it should be at the lowest practical dose and for the shortest time. When drug administration is unavoidable and breastfeeding is to continue, minimisation of exposure of the infant to the drug may sometimes be achieved by timing the maternal doses to just after a feeding episode. Infants exposed to drugs via breast milk should be monitored for unusual signs or symptoms. Interactions between the drug received by the infant from the mother's milk and medication prescribed for the infant should also be considered, for example, when the drug given to the infant may prevent metabolism of the drug received via breast milk.
