Furosemide
+ Food
The following applies to the ingredients: Furosemide
Furosemide and ethanol may have additive effects in lowering your blood pressure. You may experience headache, dizziness, lightheadedness, fainting, and/or changes in pulse or heart rate. These side effects are most likely to be seen at the beginning of treatment, following a dose increase, or when treatment is restarted after an interruption. Let your doctor know if you develop these symptoms and they do not go away after a few days or they become troublesome. Avoid driving or operating hazardous machinery until you know how the medications affect you, and use caution when getting up from a sitting or lying position. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Drug and Pregnancy Interactions
Major
Furosemide
+ Pregnancy
The following applies to the ingredients: Furosemide
Professional Content
This drug should not be used during pregnancy unless the benefit outweighs the risk to the fetus; use is contraindicated according to some authorities.
AU TGA pregnancy category: C
US FDA pregnancy category: C
Comments: Use of this drug during pregnancy requires monitoring of electrolytes, hematocrit, and fetal growth.
Animal studies have revealed evidence of fetolethality. There are no controlled data in human pregnancy.
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 C: Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.

Spiriva
+ Pregnancy
The following applies to the ingredients: Tiotropium (found in Spiriva)
Professional Content
The manufacturer makes no recommendation regarding use during pregnancy.
AU TGA pregnancy category: B1
US FDA pregnancy category: Not assigned
Comments:
-The limited data available on use in pregnant women are insufficient to know this drugs risks, including the risk of fetal harm or reproductive effects.
-Poorly controlled asthma during pregnancy increases the risk of preeclampsia, premature birth, low birth weight, and small for gestational age.
-Closely monitor asthma control during pregnancy and adjust therapy as needed for optimal control.
Animal studies showed no structural abnormalities when doses 8 and 790 times the maximum recommended human dose were administered during organogenesis; animal models showed increased fetal resorption, litter loss, and decreased numbers of live pups and pup weights, as well as a delay in pup sexual maturation at doses 40 times and 430 times the maximum recommended human dose, as well as maternal toxicity. There are no controlled data in human pregnancy. The limited human data are insufficient to inform a drug-associated risk of adverse pregnancy outcomes. 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.

The manufacturer makes no recommendation regarding use during lactation.
Excreted into human milk: Unknown
Excreted into animal milk: Yes
Comments:
-There is no information regarding this drug on the presence in human milk, the effects on a breastfed infant, or effects on milk production.
-Consider the developmental and health benefits of breastfeeding along with the mother's clinical need for this drug against any potential adverse events on the child from this drug or the mother's underlying condition.
-Lactating rats given 10 mg/kg tiotropium IV had higher concentrations of tiotropium and/or its metabolites in milk than in plasma; due to species specific differences in lactation physiology, the clinical relevance of this is unclear.
