Drug Interactions

Moderate
Trazodone + Ventolin Hfa

The following applies to the ingredients: Trazodone and Albuterol (found in Ventolin Hfa)

MONITOR: Beta-2 adrenergic agonists can cause dose-related prolongation of the QT interval and potassium loss. Theoretically, coadministration with other agents that can prolong the QT interval may result in additive effects and increased risk of ventricular arrhythmias including torsade de pointes and sudden death. In general, the risk of an individual agent or a combination of agents causing ventricular arrhythmia in association with QT prolongation is largely unpredictable but may be increased by certain underlying risk factors such as congenital long QT syndrome, cardiac disease, and electrolyte disturbances (e.g., hypokalemia, hypomagnesemia). In addition, the extent of drug-induced QT prolongation is dependent on the particular drug(s) involved and dosage(s) of the drug(s). Clinically significant prolongation of QT interval and hypokalemia occur infrequently when beta-2 agonists are inhaled at normally recommended dosages. However, these effects may be more common when the drugs are administered systemically or when recommended dosages are exceeded.

MANAGEMENT: Caution is recommended if beta-2 agonists are used in combination with other drugs that can prolong the QT interval. Patients should be advised to seek prompt medical attention if they experience symptoms that could indicate the occurrence of torsade de pointes such as dizziness, lightheadedness, fainting, palpitation, irregular heart rhythm, shortness of breath, or syncope.

Drug and Food Interactions

Moderate
Trazodone + Food

The following applies to the ingredients: Trazodone

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

Moderate
Ventolin Hfa + Food

The following applies to the ingredients: Albuterol (found in Ventolin Hfa)

MONITOR: Coadministration of two or more sympathomimetic agents may increase the risk of adverse effects such as nervousness, irritability, and increased heart rate. Central nervous system (CNS) stimulants, particularly amphetamines, can potentiate the adrenergic response to vasopressors and other sympathomimetic agents. Additive increases in blood pressure and heart rate may occur due to enhanced peripheral sympathetic activity.

MANAGEMENT: Caution is advised if two or more sympathomimetic agents are coadministered. Pulse and blood pressure should be closely monitored.

Drug and Pregnancy Interactions

The following applies to the ingredients: Trazodone

This drug should be used during pregnancy only if the benefit outweighs the risk to the fetus.
-Some experts recommend: Use with caution; use should be avoided during the first trimester of pregnancy.

US FDA pregnancy category: C

Comment: When this drug is used until delivery, newborns should be monitored for the occurrence of withdrawal symptoms.

Animal studies have revealed evidence of increased fetal resorption and congenital anomalies in adolescents. Other animal models have failed to reveal evidence of adverse effects on embryofetal development, parturition, or postnatal development when given at therapeutic doses. There are no controlled data in human pregnancy.

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.

The following applies to the ingredients: Albuterol (found in Ventolin Hfa)

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.
