Pregnancy and Lactation
Tapentadol is contraindicated in pregnancy.
At the time of writing there is limited published information regarding use during pregnancy. The manufacturer recommends using tapentadol only when the potential benefit to the mother outweighs the risk to the foetus. Animal studies have not shown any teratogenic effect, however, delayed development and embryotoxicity were observed.
The effect of tapentadol in labour and delivery in humans is unknown, therefore tapentadol is not recommended for use in women during or immediately before labour or delivery. Due to the opioid activity of tapentadol, newborn infants whose mothers have been taking tapentadol should be monitored for respiratory depression.
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 ).
Tapentadol is contraindicated in breastfeeding.
At the time of writing there is limited published information regarding use during breastfeeding.
There is no information on the excretion of tapentadol in human milk. Studies in animals have shown that tapentadol is excreted in breast milk therefore a risk to the child can not be excluded. Schaefer (2015) states that a single dose does not require any breastfeeding limitation, but repeated use is not recommended.
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.
