Drug interactions

Major drug interactions

Major:

indinavir flibanserin

Applies to: indinavir and flibanserin

Using flibanserin together with indinavir is not recommended.

Combining these medications can significantly increase the blood levels of flibanserin, which may cause excessive drowsiness and decreases in blood pressure that can lead to:

  • dizziness
  • lightheadedness
  • fainting
  • accidental injury

You should take flibanserin at bedtime to minimize the risk of these effects.

Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact.

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.

Moderate food/lifestyle interactions

Moderate:

indinavir Food/Lifestyle

Applies to: indinavir

Large amounts of food decreases the levels of indinavir in your body.

Indinavir should be taken on an empty stomach, at least 1 hour before or 2 hours after a meal. This will make it easier for your body to absorb the medication.

Take indinavir with a full glass (8 ounces) of water or skim milk. You may also drink juice, coffee, or tea with this medication.

Drink at least 6 glasses of water each day to prevent kidney stones while you are taking indinavir.

If you prefer to take the medication with food, eat only a light meal, such as dry toast with jelly, or corn flakes with skim milk and sugar. Avoid eating a high-fat meal.

Disease interactions

10 potential interactions Applies to: 9 conditions, including Hypotension, Nephrolithiasis, Diabetes Mellitus, Syncope, and Liver Disease.

Abnormal Glucose Tolerance

Moderate:

indinavir

Indinavir has a moderate potential interaction with Abnormal Glucose Tolerance.

New onset diabetes mellitus, exacerbation of preexisting diabetes mellitus, hyperglycemia, and some cases of diabetic ketoacidosis have been reported during postmarketing surveillance in HIV-infected patients treated with protease inhibitors. Some patients required either initiation or dosage adjustments of insulin or oral hypoglycemic agents for treatment of these events. In some cases, hyperglycemia persisted despite discontinuation of protease inhibitor therapy. A causal relationship has not been established between protease inhibitor therapy and these events. Monitoring patients for hyperglycemia, new onset diabetes mellitus, or exacerbation of diabetes mellitus should be considered during protease inhibitor therapy.

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.

Dehydration

Major:

indinavir

Indinavir has a major potential interaction with Dehydration.

Crystalluria and nephrolithiasis may occur during treatment with indinavir. The cumulative frequency of nephrolithiasis is substantially higher in pediatric patients (29%) than in adult patients (12.4%; range 4.7% to 34.4% across individual trials) and increases with duration of exposure to indinavir; however, the risk over time remains relatively constant. The incidence is also higher when indinavir is used in combination with ritonavir than when used alone at 800 mg three times a day. In some cases, nephrolithiasis/urolithiasis has been associated with renal insufficiency or acute renal failure and pyelonephritis with or without bacteremia. Therapy with indinavir should be administered cautiously in patients with a current or past history of nephrolithiasis. It is crucial that patients receive adequate hydration. Generally, at least 1.5 L (approximately 48 oz) of fluid per day is recommended for adults during indinavir therapy. Those who are dehydrated may be at increased risk and should be encouraged to consume additional amounts of liquid or given intravenous fluid if necessary. All patients receiving indinavir should be instructed to seek medical attention if they experience potential signs and symptoms of nephrolithiasis/urolithiasis such as flank pain, hematuria, dysuria, anuria, and urinary urgency. A brief interruption (e.g., 1 to 3 days) or discontinuation of therapy may be required.

Diabetes Mellitus

Moderate:

indinavir

Indinavir has a moderate potential interaction with Diabetes Mellitus.

New onset diabetes mellitus, exacerbation of preexisting diabetes mellitus, hyperglycemia, and some cases of diabetic ketoacidosis have been reported during postmarketing surveillance in HIV-infected patients treated with protease inhibitors. Some patients required either initiation or dosage adjustments of insulin or oral hypoglycemic agents for treatment of these events. In some cases, hyperglycemia persisted despite discontinuation of protease inhibitor therapy. A causal relationship has not been established between protease inhibitor therapy and these events. Monitoring patients for hyperglycemia, new onset diabetes mellitus, or exacerbation of diabetes mellitus should be considered during protease inhibitor therapy.

History, Nephrolithiasis

Major:

indinavir

Indinavir has a major potential interaction with History, Nephrolithiasis.

Crystalluria and nephrolithiasis may occur during treatment with indinavir. The cumulative frequency of nephrolithiasis is substantially higher in pediatric patients (29%) than in adult patients (12.4%; range 4.7% to 34.4% across individual trials) and increases with duration of exposure to indinavir; however, the risk over time remains relatively constant.

A brief interruption (e.g., 1 to 3 days) or discontinuation of therapy may be required.

Hypotension

Major:

flibanserin

Flibanserin has a major potential interaction with Hypotension.

The use of flibanserin can cause hypotension and syncope. The benefits and risks of therapy should be considered in patients with preexisting conditions that predispose to hypotension. Flibanserin should be used with caution in these patients.

Liver Disease

Major:

flibanserin

Flibanserin has a major potential interaction with Liver Disease.

Flibanserin may accumulate in patients with hepatic impairment. Therapy with flibanserin is contraindicated in patients with compromised hepatic function.

Moderate:

indinavir

Indinavir has a moderate potential interaction with Liver Disease.

Indinavir is primarily metabolized by the liver. Patients with liver disease may be at greater risk for adverse effects from indinavir due to decreased drug clearance. Therapy with indinavir should be administered cautiously in patients with liver disease. A dosage reduction to 600 mg three times a day is recommended for patients with mild to moderate hepatic insufficiency due to cirrhosis.

Nephrolithiasis

Major:

indinavir

Indinavir has a major potential interaction with Nephrolithiasis.

Crystalluria and nephrolithiasis may occur during treatment with indinavir. The cumulative frequency of nephrolithiasis is substantially higher in pediatric patients (29%) than in adult patients (12.4%; range 4.7% to 34.4% across individual trials) and increases with duration of exposure to indinavir; however, the risk over time remains relatively constant.
