Drug and Food Interactions
Moderate
Clonazepam
+ Food
The following applies to the ingredients: Clonazepam
GENERALLY AVOID: Acute ethanol ingestion may potentiate the CNS effects of many benzodiazepines. Tolerance may develop with chronic ethanol use. The mechanism may be decreased clearance of the benzodiazepines because of CYP450 hepatic enzyme inhibition. Also, it has been suggested that the cognitive deficits induced by benzodiazepines may be increased in patients who chronically consume large amounts of alcohol.
MANAGEMENT: Patients should be advised to avoid alcohol during benzodiazepine therapy.

Drug and Pregnancy Interactions
Major
Clonazepam
+ Pregnancy
The following applies to the ingredients: Clonazepam
This drug should be used during pregnancy only if clearly needed and the benefit outweighs the risk.
AU TGA pregnancy category: B3
US FDA pregnancy category: Not assigned.
Risk summary: There are inconclusive data available on use of this drug in pregnant women to inform a drug-related risk.
Comments:
-The child born to a mother taking benzodiazepines may be at risk for withdrawal symptoms.
-Supplementation with folic acid is recommended before conception and during pregnancy.
-Pregnancy itself, and discontinuation of treatment, may result in exacerbation of epilepsy.
-The patient should be warned of the potential risks to the fetus prior to initiation; patients who become pregnant should continue treatment, and monotherapy should be used at the lowest effective dose (if possible).
Animal studies have revealed evidence of decreased number of pregnancies, lower number of surviving offspring until weaning, malformations, decreased maternal weight gain, and reduced fetal growth. There have been reports of neonatal flaccidity, respiratory and feeding difficulties, irregular heart rate, and hypothermia in children born to mothers who have been taking benzodiazepines late in pregnancy. There are no controlled data in human pregnancy.
To monitor maternal-fetal outcome of pregnant women exposed to antiepileptic drugs, the North American Antiepileptic Drug (NAAED) Pregnancy Registry has been established. Healthcare providers are encouraged to prospectively register patients. For additional information: http://www.aedpregnancyregistry.org/
AU TGA pregnancy category B3: 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 shown evidence of an increased occurrence of fetal damage, the significance of which is considered uncertain in humans.
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.

Major
Fish Oil
+ Pregnancy
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
Major
Clonazepam
+ Breastfeeding
