Drug Interactions

Minor
Norvasc + Lisinopril

The following applies to the ingredients: Amlodipine (found in Norvasc) and Lisinopril

Calcium channel blockers and angiotensin converting enzyme (ACE) inhibitors may have additive hypotensive effects. While these drugs are often safely used together, careful monitoring of the systemic blood pressure is recommended during coadministration, especially during the first one to three weeks of therapy.

Drug and Food Interactions

Moderate
Lisinopril + Food

The following applies to the ingredients: Lisinopril

GENERALLY AVOID: Moderate-to-high dietary intake of potassium can cause hyperkalemia in some patients who are using angiotensin converting enzyme (ACE) inhibitors. In some cases, affected patients were using a potassium-rich salt substitute. ACE inhibitors can promote hyperkalemia through inhibition of the renin-aldosterone-angiotensin (RAA) system.

MANAGEMENT: It is recommended that patients who are taking ACE inhibitors be advised to avoid moderately high or high potassium dietary intake. Particular attention should be paid to the potassium content of salt substitutes.

The following applies to the ingredients: Lisinopril

MONITOR: Many psychotherapeutic and CNS-active agents (e.g., anxiolytics, sedatives, hypnotics, antidepressants, antipsychotics, opioids, alcohol, muscle relaxants) exhibit hypotensive effects, especially during initiation of therapy and dose escalation. Coadministration with antihypertensives and other hypotensive agents, in particular vasodilators and alpha-blockers, may result in additive effects on blood pressure and orthostasis.

MANAGEMENT: Caution and close monitoring for development of hypotension is advised during coadministration of these agents. Some authorities recommend avoiding alcohol in patients receiving vasodilating antihypertensive drugs. Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia.

MONITOR: Calcium-containing products may decrease the effectiveness of calcium channel blockers by saturating calcium channels with calcium. Calcium chloride has been used to manage acute severe verapamil toxicity.

MANAGEMENT: Management consists of monitoring the effectiveness of calcium channel blocker therapy during coadministration with calcium products.

Minor
Norvasc + Food

The following applies to the ingredients: Amlodipine (found in Norvasc)

The consumption of grapefruit juice may slightly increase plasma concentrations of amlodipine. The mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. Data have been conflicting and the clinical significance is unknown. Monitoring for calcium channel blocker adverse effects (e.g., headache, hypotension, syncope, tachycardia, edema) is recommended.

Drug and Pregnancy Interactions

The following applies to the ingredients: Amlodipine (found in Norvasc)

This drug should be used during pregnancy only if the benefit outweighs the risk to the fetus (AU, US)
Use is contraindicated (UK)

AU TGA pregnancy category: C
US FDA pregnancy category: C

Comments:
-Use of adequate methods of contraception should be encouraged.
-If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential harm to the fetus.

Animal studies have shown significantly decreased litter size, increased intrauterine deaths and prolongation of gestation and duration of labor when this drug was given before mating, throughout mating, and during gestation. There are no controlled data in human pregnancy.

Reversible biochemical changes in the head of spermatozoa occurred in some patients treated with calcium channel blockers. There are no controlled data for this drug, but animal models have shown adverse effects on male fertility.

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.

The following applies to the ingredients: Lisinopril

AU: Use is contraindicated.
UK: Use is not recommended during the first trimester and use is contraindicated during the second and third trimesters.
US: This drug should not be used during pregnancy unless there are no alternatives and the benefit outweighs the risk to the fetus.

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

Risk Summary: Use of drugs that act on the renin angiotensin system (RAS) during the second and third trimesters of pregnancy increases fetal and neonatal morbidity and death.

Comments:
-Adequate methods of contraception should be encouraged.
-Advise pregnant women and females of reproductive potential of the potential risk to a fetus.

Animal studies have revealed evidence of fetotoxicity. In humans, exposure to angiotensin-converting enzyme (ACE) inhibitors during the second and third trimesters has revealed evidence of fetal and neonatal toxicity and fetolethality. There are no controlled data in human pregnancy.

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.
