Drug Interactions

Moderate
Ibuprofen + Fish Oil

The following applies to the ingredients: Ibuprofen and Omega-3 Polyunsaturated Fatty Acids (found in Fish Oil)

MONITOR: Omega-3 fatty acids (e.g., fish oil) may potentiate the pharmacologic effects of anticoagulants and other drugs that affect hemostasis such as platelet inhibitors, thrombin inhibitors, thrombolytic agents, dextran, and nonsteroidal anti-inflammatory drugs (NSAIDs). The exact mechanism of interaction is unknown. Omega-3 fatty acids may possess mild antiplatelet and hypocoagulant activities. In some studies, these substances have been shown to reduce thrombin generation and plasma levels of fibrinogen, prothrombin, and coagulation factors V, VII, and X. Prolongation of bleeding time has been demonstrated, although it did not exceed normal limits and did not produce clinically significant bleeding. The interaction was suspected in a case report of a 67-year-old woman treated with warfarin for 1.5 years who exhibited an increase in INR from 2.8 the previous month to 4.3 approximately one week after doubling her fish oil dosage from 1000 to 2000 mg/day. Prior to the increase, her INR had been stable and therapeutic for 5 months on warfarin 1.5 mg/day. The patient was advised to reduce her fish oil consumption to 1000 mg/day, while her warfarin dose was withheld for one day and then reduced to 1 mg alternating with 1.5 mg per day. Eight days later, her INR was subtherapeutic at 1.6, so the warfarin dosage was increased back to 1.5 mg/day. The patient's INR subsequently returned to therapeutic range.

MANAGEMENT: In general, patients should consult a healthcare provider before taking any herbal or nutritional supplements. Patients using omega-3 fatty acids in combination with anticoagulants or other drugs that affect hemostasis should be advised of the potential for increased risk of bleeding complications.

Drug and Food Interactions

Moderate
Ibuprofen + Food

The following applies to the ingredients: Ibuprofen

GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.

MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.

Drug and Pregnancy Interactions

The following applies to the ingredients: Ibuprofen

Contraindicated last trimester of pregnancy
NSAIDs should be avoided at 20 weeks gestation and later

AU TGA pregnancy category C
US FDA pregnancy category: Not assigned

Risk Summary: Nonsteroidal anti-inflammatory drugs (NSAIDs) use in pregnant women at 30 weeks gestation and later may cause premature closure of the fetal ductus arteriosus; NSAID use at 20 weeks gestation or later may cause fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment.

Comments:
-NSAID use in pregnancy prior to 20 weeks gestation should be based on a benefit-risk assessment; some authorities recommend avoiding NSAIDs throughout pregnancy whenever possible.
-If NSAID use is necessary between 20- and 30-weeks' gestation, limit use to the lowest effective dose for the shortest duration possible; ultrasound monitoring of amniotic fluid should be considered if NSAID use extends beyond 48 hours; if oligohydramnios occurs, discontinue NSAID and treat appropriately.
-NSAID use is not recommended in women attempting to conceive as it may impair female fertility.

Published reports have not shown clear developmental effects in animal studies with dosing up to 0.4 (rabbits) and 0.5 (rats) times the maximum recommended human dose (MRHD) throughout gestation. In rats, dosed at 0.8 times the MRHD on gestation days 9 and 10, an increase in membranous ventricular septal defects was reported; maternal toxicity was also reported. Animal data has shown that prostaglandins play an important role in endometrial vascular permeability, blastocyst implantation, and decidualization; administration of prostaglandin synthesis inhibitors such as this drug, has been shown to result in increased pre-and post-implantation loss. Data from epidemiological studies suggest an increased risk of miscarriage and of cardiac malformation and gastroschisis after use of a prostaglandin synthesis inhibitor in early pregnancy. The absolute risk for cardiovascular malformation was increased from less than 1%, up to approximately 1.5 %. The risk is believed to increase with dose and duration of therapy. There are no controlled data in human pregnancy.

US FDA Drug Safety Communication (10-2020): The FDA is requiring a new warning be added to NSAID labeling describing the risk of fetal kidney problems that may result in low amniotic fluid. The FDA is recommending pregnant women avoid NSAID use at 20 weeks gestation or later. Through 2017, the FDA has received 35 reports of low amniotic fluid levels or kidney problems in mothers who took NSAIDs while pregnant. Five newborns died; 2 had kidney failure and confirmed low amniotic fluid, 3 had kidney failure without confirmed low amniotic fluid. The low amniotic fluid started as early as 20 weeks of pregnancy. There were 11 reports of low amniotic fluid levels during pregnancy and the fluid volume returned to normal after the NSAID was stopped. The medical literature has reported low amniotic fluid levels with use of NSAIDs for varying amounts of time, ranging from 48 hours to multiple weeks. Complications of prolonged oligohydramnios may include limb contractures and delayed lung maturation. In some postmarketing cases of impaired neonatal renal function, invasive procedures such as exchange transfusion or dialysis were required. In other cases, the condition was reversible within 3 to 6 days of stopping the NSAID and in these cases reappeared when the same NSAID was restarted.

Administration during labor and delivery is not recommended; onset of labor may be delayed, and duration increased with greater bleeding tendency in mother and child.

NSAIDs may impair female fertility; withdrawal of NSAID therapy should be considered in women with difficulties conceiving or who are undergoing investigation of infertility.

AU TGA pregnancy category C: Drugs which, owing to their pharmacological effects, have caused or may be suspected of causing, harmful effects on the human fetus or neonate without causing malformations. These effects may be reversible. Accompanying texts should be consulted for further details.

US FDA pregnancy category Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D, and X are being phased out.

The following applies to the ingredients: Omega-3 Polyunsaturated Fatty Acids (found in Fish Oil)

Use is recommended only if clearly needed.

AU TGA pregnancy category: B1
US FDA pregnancy category: Not assigned

Comments:
-There is insufficient data on use in pregnancy to identify drug-associate risks for major birth defects, miscarriage, or adverse fetal or maternal outcomes.
-Animal studies of dams given oral omega-3-acid ethyl esters from mating through lactation did not show adverse reproductive or developmental effects at 5 times the maximum recommended human dose (MRHD).
-Animal studies of oral dosing at clinically relevant doses during organogenesis did not show teratogenicity.
-There is no official RDA for omega-3 fatty acids during pregnancy, but the US Institute of Medicine and the Food and Nutrition Board suggest that 1400 mg per day should be adequate during lactation.
-Pregnant women may not consume adequate amounts of omega-3 fatty acids from their diet due to recommendations to limit fish consumption to no more than twice weekly (due to mercury content of fish).

Animal studies of oral administration from 2 weeks prior to mating through lactation showed no adverse effects at 5 times the recommended human dose (MRHD). A dose ranging study of oral administration from 2 weeks prior to mating to postpartum day 7 showed a 20% reduction in live births and a 40% reduction in pup survival to postnatal day 4 at or above 3000 mg/kg/day (7 times the MRHD). Oral doses up to 14 times the MRHD (a maternotoxic dose) administered during organogenesis showed no fetal adverse effects. Animals given oral doses up to 5 times the MRHD from gestation day 14 through lactation day 21 showed no adverse effects. Skeletal malformations and reduced fetal growth were seen at maternally toxic doses (4 times the MRHD) and embryolethality occurred at 7 times the MRHD in rabbits. There are no controlled data in human pregnancy. Adequate omega-3 fatty acid intake during pregnancy may reduce preterm birth, increase birth length, weight, and head circumference, improve cognitive and visual development, and reduce risk of allergies. The background birth defect and miscarriage risk for the indicated population is not known. In the US general population, the estimated major birth defect risk is 2 to 4% and the miscarriage risk is 15 to 20%.


AU TGA pregnancy category B1: Drugs which have been taken by only a limited number of pregnant women and women of childbearing age, without an increase in the frequency of malformation or other direct or indirect harmful effects on the human fetus having been observed. Studies in animals have not shown evidence of an increased occurrence of fetal damage.

US FDA pregnancy category Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D, and X are being phased out.

Drug and Breastfeeding Interactions

The following applies to the ingredients: Ibuprofen

Benefit should outweigh risk

Excreted into human milk: Yes (small amounts)

Comments: Adverse effects on the breastfed infant and effects on milk production have not been reported.

This drug is a preferred choice as an analgesic/anti-inflammatory agent in nursing mothers because of the very low levels in breastmilk and demonstrated safety with therapeutic administration to infants at doses much higher than those excreted in breast milk. Limited published reports indicate that following oral administration, this drug is present in human milk at relative infant doses of 0.06% to 0.6% of the maternal weight-adjusted daily dose. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for this drug and any potential adverse effects to the breastfed infant from the drug or from the underlying maternal condition.
