In males receiving LHRH agonists a reduction in glucose tolerance has been observed. This may present itself as diabetes or loss of glycaemic control in those with pre-existing diabetes. Consideration should be given to monitoring blood glucose in patients receiving bicalutamide in combination with LHRH agonists.
Pregnancy and Lactation
Bicalutamide is contraindicated in women.
There are no data available on the use of bicalutamide during pregnancy, as bicalutamide is only indicated for use in men. Bicalutamide must not be given to pregnant women.
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 to 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 ).
Bicalutamide is contraindicated in women.
There are no data available on the use of bicalutamide during breastfeeding, as bicalutamide is only indicated for use in men. Bicalutamide must not be given to women during breastfeeding.
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.
