Drug and Food Interactions
Moderate
Atorvastatin
+ Food
The following applies to the ingredients: Atorvastatin
Grapefruit juice can increase the blood levels of atorvastatin. This can increase the risk of side effects such as liver damage and a rare but serious condition called rhabdomyolysis that involves the breakdown of skeletal muscle tissue. In some cases, rhabdomyolysis can cause kidney damage and even death. You should limit your consumption of grapefruit juice to no more than 1 quart per day during treatment with atorvastatin. Let your doctor know immediately if you have unexplained muscle pain, tenderness, or weakness during treatment, especially if these symptoms are accompanied by fever or dark colored urine. You should also seek immediate medical attention if you develop fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, dark colored urine, and/or yellowing of the skin or eyes, as these may be signs and symptoms of liver damage. 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.
Moderate
Proair Hfa
+ Food
The following applies to the ingredients: Albuterol (found in Proair Hfa)
Both albuterol and caffeine can increase blood pressure and heart rate, and combining them may enhance these effects. Talk to your doctor before using these medications, especially if you have a history of high blood pressure or heart disease. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. 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
Proair Hfa
+ Pregnancy
The following applies to the ingredients: Albuterol (found in Proair Hfa)
Professional Content
The manufacturer makes no recommendation regarding use during pregnancy.
AU TGA pregnancy category: A
US FDA pregnancy category: Not assigned
Comments:
-There are no randomized clinical studies of albuterol use during pregnancy, but available information on pregnancy exposure by inhalation do not consistently show miscarriage or major birth defects.
-This drug is known to cross the placental barrier, as evidenced by increases in fetal heart rate.
-Beta-agonists, including this drug, may potentially interfere with uterine contractility.
-In women with poorly or moderately controlled asthma, there is an increased risk of preeclampsia in the mother and prematurity, low birth weight, and small for gestational age in the neonate. Pregnant women should be closely monitored and the dose adjusted as necessary to maintain optimal control.
-In some countries, intravenous injection presentations of this drug have been approved for delay pre-term labor (tocolytic agent) and should not be used in the management of uncomplicated premature labor.
Epidemiological studies and postmarketing case reports following inhaled administration of this drug do not consistently demonstrate a risk of major birth defects or miscarriage. In animal reproduction studies, subcutaneous administration to pregnant mice evidence of cleft palate at less than and up to 9 times the maximum recommended human daily inhalation dose (MRHDID). A study in pregnant rats demonstrated that drug-related material was transferred from the maternal circulation to the fetus. There are no controlled data in human pregnancy.
During worldwide marketing experience, various congenital anomalies, including cleft palate and limb defects, have been reported in the offspring of patients being treated with this drug. Some of the mothers were taking multiple medications during their pregnancies. A relationship between the use of this drug and congenital anomalies has not been established. Profuse uterine bleeding following spontaneous abortion has been reported after the use of this drug. Special care is required in pregnant diabetic women. 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%.
A pregnancy exposure registry monitors outcomes after exposure to asthma medications during pregnancy. For more information, contact the Mothers To Baby Pregnancy Studies conducted by the Organization of Teratology Information Specialists at http://mothertobaby.org/pregnancystudies/.
AU TGA pregnancy category A: Drugs which have been taken by a large number of pregnant women and women of childbearing age without any proven increase in the frequency of malformations or other direct or indirect harmful effects on the fetus having been observed.
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
Atorvastatin
+ Pregnancy
The following applies to the ingredients: Atorvastatin
Professional Content
According to some authorities: Use is contraindicated during pregnancy or in patients of childbearing potential not using contraception.
AU TGA pregnancy category: D
US FDA pregnancy category: Not assigned
Risk summary: Based on its mechanism of action, this drug may cause fetal harm when administered during pregnancy.
-Available data on the use of statins in pregnant women have not identified a drug-related risk of major congenital malformations and are insufficient to inform a drug-related risk of miscarriage.
Comments:
-If the patient becomes pregnant while taking this drug, therapy should be discontinued and the patient should be apprised of the potential harm to the fetus.
---According to some authorities: Alternatively, the ongoing needs of the individual patient should be considered.
-According to some authorities: Patients of childbearing potential should use effective contraception during therapy; this drug should be used in patients of childbearing potential only when they are highly unlikely to conceive and have been informed of the potential.
Animal studies have failed to reveal evidence of embryofetal toxicity or teratogenicity; however, at maternally toxic doses, increased postimplantation loss and decreased fetal body weights have been observed. No adverse developmental effects were observed in pregnant rats or rabbits administered oral doses that resulted in up to 30 and 20 times, respectively, the human exposure at the maximum recommended human dose (MRHD) of 80 mg (based on body surface area [mg/m2]); in rats administered this drug during gestation and lactation, decreased postnatal growth and development delay were observed at doses at least 6 times the MRHD. This drug crosses the rat placenta and reaches levels in the fetal liver equivalent to that of maternal plasma. A study of statin-exposed pregnant women compared to controls did not find a significant teratogenic effect from maternal use of statins in the first trimester, after adjusting for potential confounders. Rare cases of congenital anomalies after intrauterine exposure to HMG-CoA reductase inhibitors have been reported. There are no controlled data in human pregnancy.
Cholesterol and other products of cholesterol biosynthesis are essential components for fetal development (including synthesis of steroids and cell membranes). Because this drug decreases synthesis of cholesterol and possibly other biologically active substances derived from cholesterol, it may cause fetal harm when used during pregnancy.
Treatment of hyperlipidemia is not generally necessary during pregnancy. Since atherosclerosis is a chronic process, discontinuation of lipid-lowering drugs during pregnancy should have little impact on the outcome of long-term primary hypercholesterolemia therapy for most patients.
AU TGA pregnancy category D: Drugs which have caused, are suspected to have caused or may be expected to cause, an increased incidence of human fetal malformations or irreversible damage. These drugs may also have adverse pharmacological effects. 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.

Major
Atorvastatin
+ Breastfeeding
The following applies to the ingredients: Atorvastatin
Professional Content
Until more data are available, an alternate agent may be preferred, particularly while breastfeeding newborn or preterm infants.
-According to some authorities: Breastfeeding is not recommended during use of this drug.
-According to some authorities: Use is contraindicated.
Excreted into human milk: Unknown
Excreted into animal milk: Yes
Comments:
-Another drug in this class is excreted into human milk.
-Statins (including this drug) decrease synthesis of cholesterol and possibly other biologically active substances derived from cholesterol; they may cause harm to the breastfed infant.
-The effects in the nursing infant are unknown; based on the mechanism of action, there is the potential for serious adverse reactions in nursing infants.
Due to a concern over disruption of infant lipid metabolism, it is generally agreed that women taking a statin should not breastfeed; however, others have argued that children homozygous for familial hypercholesterolemia are treated with statins starting at 1 year of age, statins have low oral bioavailability, and risks to the breastfed infant are low. Some evidence indicates that this drug can be taken by nursing mothers with no obvious developmental problems in their infants.
In cases of patients with homozygous familial hypercholesterolemia, 6 patients breastfed 11 infants after restarting statin therapy postpartum; the specific statin was not reported, but most of the women on statin therapy were using this drug (40 or 80 mg/day). Normal early child development was reported for all offspring; children started school at the appropriate age with no learning difficulties reported.
