Drug interactions

Moderate drug interactions

Moderate:

cyclobenzaprine flibanserin

Applies to: Amrix (cyclobenzaprine) and flibanserin

Using flibanserin together with cyclobenzaprine may increase side effects such as:

  • dizziness
  • drowsiness
  • fatigue
  • difficulty concentrating

You should avoid the use of alcohol while being treated with these medications. Also avoid activities requiring mental alertness such as driving or operating hazardous machinery for at least 6 hours after taking flibanserin and until you know how the medications affect you.

Talk to your doctor if you have any questions or concerns. 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.

Food/lifestyle interactions

Major food/lifestyle interactions

Major:

flibanserin Food/Lifestyle

Applies to: flibanserin

Do not use alcohol too close to the dosing time of flibanserin. Doing so can cause excessive drowsiness and decreases in blood pressure, which may lead to:

  • dizziness
  • lightheadedness
  • fainting
  • accidental injury

What to do: Take flibanserin at bedtime to minimize the risk of these effects. It is recommended that you stop drinking alcohol at least two hours before taking flibanserin; otherwise, you should just skip the flibanserin dose that evening. Alcohol should not be consumed until at least the morning after taking flibanserin at bedtime.

Because grapefruit juice can significantly increase the blood levels of flibanserin, you should also avoid the consumption of grapefruit and grapefruit juice during treatment.

Talk to your healthcare provider if you have any questions or concerns. 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.

  • drowsiness
  • difficulty concentrating

Some people may also experience impairment in thinking and judgment.

You should avoid or limit the use of alcohol while being treated with cyclobenzaprine.

Do not use more than the recommended dose of cyclobenzaprine, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you.

Disease interactions

15 potential interactions Applies to: 14 conditions, including Heart Failure, Hypotension, Hyperthyroidism, Syncope, and Urinary Retention.

Alcoholism

Major:

flibanserin

Flibanserin has a major potential interaction with Alcoholism.

The use of flibanserin is contraindicated along with the ingestion of alcohol, as it increases the risk of hypotension and syncope. It is important to assess the likelihood of the patient abstaining from alcohol, taking into account the current and past drinking behavior.

Cardiovascular Conditions and Disorders

Major:

Amrix

The cyclobenzaprine in Amrix has a major potential interaction with Cardiovascular Conditions and Disorders.

The manufacturers consider the use of cyclobenzaprine to be contraindicated in the acute recovery phase following myocardial infarction and in patients with hyperthyroidism, congestive heart failure, arrhythmias, heart block, and/or conduction disturbances. Cyclobenzaprine is structurally related to the tricyclic antidepressants, which have been reported to cause tachycardia, arrhythmias, heart block, hypertension, hypotension (particularly orthostatic hypotension), thrombosis, thrombophlebitis, myocardial infarction, strokes, congestive heart failure, and ECG abnormalities such as PR and QT interval prolongation. Therapy with cyclobenzaprine should be administered cautiously in patients with a history of cardiovascular or cerebrovascular disease or a predisposition to hypotension, particularly if the intended dosage exceeds those normally used for musculoskeletal conditions. Tachycardia, arrhythmia, palpitation, and hypotension have been reported with the use of cyclobenzaprine in less than 1% of patients.
