Interaction Effect
Slowing of the heart rate or atrioventricular conduction, which may result in severe bradycardia or heart block
Interaction Summary
The concomitant use of fingolimod and metoprolol may cause an additional decrease in heart rate and atrioventricular conduction and may result in severe bradycardia and heart block. Evaluate the possibility of switching from metoprolol to a drug that does not lower heart rate or slow atrioventricular conduction prior to fingolimod initiation. If treatment with metoprolol is necessary, extended monitoring is recommended, including continuous overnight ECG monitoring after the first fingolimod dose .

Metoprolol Overview
-
Metoprolol is used alone or in combination with other medications to treat high blood pressure. It also is used to treat chronic (long-term) angina (chest pain). Metoprolol is also used to improve survival after a heart attack. Metoprolol also is used in combination with other medications to treat heart failure. Metoprolol is in a class of medications called beta blockers. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure.
-
High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.
Fingolimod Overview
-
Fingolimod is used to prevent episodes of symptoms and slow the worsening of disability in adults and children 10 years of age and older with relapsing-remitting forms (course of disease where symptoms flare up from time to time) of multiple sclerosis (MS; a disease in which the nerves do not function properly and people may experience weakness, numbness, loss of muscle coordination, and problems with vision, speech, and bladder control). Fingolimod is in a class of medications called sphingosine l-phosphate receptor modulators. It works by decreasing the action of immune cells that may cause nerve damage.

Definitions
Severity Categories
Contraindicated
These drugs, generally, should not be used together simultaneously due to the high risk of severe adverse effects. Combining these medications can lead to dangerous health outcomes and should be strictly avoided unless otherwise instructed by your provider.
Major
This interaction could result in very serious and potentially life-threatening consequences. If you are taking this drug combination, it is very important to be under close medical supervision to minimize severe side effects and ensure your safety. It may be necessary to change a medication or dosage to prevent harm.
Moderate
This interaction has the potential to worsen your medical condition or alter the effectiveness of your treatment. It's important that you are monitored closely and you potentially may need to make adjustments in your treatment plan or drug dosage to maintain optimal health.
Minor
While this interaction is unlikely to cause significant problems, it could intensify side effects or reduce the effectiveness of one or both medications. Monitoring for changes in symptoms and your condition is recommended, and adjustments may be made if needed to manage any increased or more pronounced side effects.
Onset
Rapid: Onset of drug interaction typically occurs within 24 hours of co-administration.
Delayed: Onset of drug interaction typically occurs more than 24 hours after co-administration.
Evidence
Level of documentation of the interaction.
Established: The interaction is documented and substantiated in peer-reviewed medical literature.
Theoretical: This interaction is not fully supported by current medical evidence or well-documented sources, but it is based on known drug mechanisms, drug effects, and other relevant information.
