Use of NSAIAs during pregnancy at about >=30 weeks' gestation can cause premature closure of the fetal ductus arteriosus, and use at about >=20 weeks' gestation has been associated with fetal renal dysfunction resulting in oligohydramnios and, in some cases, neonatal renal impairment. Because of these risks, use of NSAIAs should be avoided in pregnant women at about >=30 weeks' of gestation; if NSAIA therapy is necessary between about 20-30 weeks' gestation, the lowest effective dosage and shortest possible duration of treatment should be used. Monitoring of amniotic fluid volume via ultrasound examination should be considered if the duration of NSAIA treatment exceeds 48 hours; if oligohydramnios occurs, the drug should be discontinued and follow-up instituted according to clinical practice.

Pregnant women should be advised to avoid use of NSAIAs beginning at 20 weeks' gestation unless otherwise advised by a clinician; they should be informed that NSAIAs should be avoided beginning at 30 weeks' gestation because of the risk of premature closure of the fetal ductus arteriosus and that monitoring for oligohydramnios may be necessary if NSAIA therapy is required for longer than 48 hours' duration between about 20-30 weeks of gestation. Fetal renal dysfunction resulting in oligohydramnios and, in some cases, neonatal renal impairment has been observed, on average, following days to weeks of maternal NSAIA use, although oligohydramnios has been observed infrequently as early as 48 hours after initiation of NSAIA therapy. Oligohydramnios is often, but not always, reversible following discontinuance of NSAIA therapy.

Complications of prolonged oligohydramnios may include limb contracture and delayed lung maturation. A limited number of case reports have described maternal NSAIA use and neonatal renal dysfunction, in some cases irreversible, without oligohydramnios. Some cases of neonatal renal dysfunction have required treatment with invasive procedures such as exchange transfusion or dialysis.

Methodologic limitations of these postmarketing studies and case reports include lack of a control group; limited information regarding dosage, duration, and timing of drug exposure; and concomitant use of other drugs. These limitations preclude establishing a reliable estimate of the risk of adverse fetal and neonatal outcomes with maternal NSAIA use. Available data on neonatal outcomes generally involved preterm infants, and the extent to which certain reported risks can be generalized to full-term infants is uncertain.

There are no studies evaluating the effects of diclofenac on labor and delivery in humans. In animal studies, NSAIAs, including diclofenac, inhibit prostaglandin synthesis, delay parturition, and increase the incidence of stillbirth. Diclofenac sodium in fixed combination with misoprostol is contraindicated in women who are pregnant because misoprostol exhibits abortifacient activity and can cause serious fetal harm. In addition, it is recommended that diclofenac in fixed combination with misoprostol be used in women of reproductive potential only if they require NSAIA therapy and are considered at high risk of complications resulting from NSAIA-induced gastric or duodenal ulceration or at high risk of developing gastric or duodenal ulceration.

Diclofenac may be distributed into human milk. While diclofenac was not detectable in breast milk in 12 women who received diclofenac 100 mg orally daily for 7 days or a single 50-mg IM dose administered in the immediate postpartum period, the drug was detected in breast milk at a concentration of 100 mcg/L (equivalent to an infant dose of about 0.03 mg/kg daily) in one woman receiving a diclofenac salt at a dosage of 150 mg daily. The developmental and health benefits of breast-feeding should be considered along with the mother's clinical need for diclofenac and any potential adverse effects on the breast-fed infant from the drug or from the underlying maternal condition.

Geriatric patients are at increased risk for NSAIA-associated serious adverse cardiovascular, GI, and renal effects. The risk of these adverse effects may be increased in geriatric patients with renal impairment or receiving concomitant ACE inhibitor or angiotensin II receptor antagonist therapy. Many of the spontaneous reports of fatal adverse GI effects in patients receiving NSAIAs involve geriatric individuals.

If the anticipated benefits of diclofenac therapy outweigh the potential risks, diclofenac should be initiated at the lower end of the dosing range and patients should be monitored for adverse effects. Diclofenac sodium in fixed combination with misoprostol should be avoided in geriatric patients with cardiovascular and/or renal risk factors. In clinical trials of diclofenac sodium in fixed combination with misoprostol, 25.5%

of patients were >=65 years of age. No overall differences in efficacy were observed between geriatric patients and younger adults. Other clinical experience has not identified differences in response compared to younger adults, although a greater sensitivity to the drug cannot be ruled out in older individuals.

No clinically meaningful differences in diclofenac and misoprostol pharmacokinetics were observed in geriatric patients compared to younger adults. In phase 3 clinical trials of diclofenac sodium 1.5% topical solution, 49% of patients receiving the drug were >=65 years of age.

In an open-label, long-term safety study, 42% of patients receiving diclofenac sodium 1.5% topical solution were >=65 years of age, while 13% were >=75 years of age. No age-related differences in the incidence of adverse effects were observed in these studies.

Clinical trials of diclofenac epolamine transdermal system or diclofenac potassium oral solution did not include sufficient numbers of patients >=65 years of age to determine whether they respond differently than younger adults. Other clinical experience has not identified differences in response between geriatric and younger patients. Diclofenac is substantially excreted by the kidneys, and the risk of toxicity may be greater in patients with renal impairment. Because geriatric patients are more likely to have decreased renal function, diclofenac should be used with caution; it may be useful to monitor renal function in such patients.
