etodolac in pregnancy
Etodolac should not be used in the last trimester of pregnancy. From week 20 it may affect the baby's kidneys, amniotic-fluid volume and ductus arteriosus, so it should be avoided unless a clinician considers it necessary. Exposure over several days may require antenatal monitoring. Discuss pregnancy or plans to conceive with the prescriber because NSAIDs may impair female fertility.
etodolac while breastfeeding
Evidence specific to etodolac during breastfeeding is limited, and the selected product information advises avoiding it where possible. UK specialist guidance prefers ibuprofen or diclofenac when an NSAID is needed for a full-term, healthy breastfed infant. Ask the prescriber to review treatment.
etodolac interactions
Check prescribed, over-the-counter and herbal products with a pharmacist or prescriber. Important interactions include:
Other NSAIDs, including ibuprofen, naproxen and aspirin
Combining NSAIDs increases gastrointestinal and other adverse effects and should be avoided unless specifically directed.
Warfarin and other anticoagulants
Etodolac can enhance anticoagulant effects and increase bleeding risk.
Antiplatelets, SSRIs and corticosteroids
These combinations increase the risk of gastrointestinal ulceration or bleeding.
