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:

efavirenz Food/Lifestyle

Applies to: Atripla (efavirenz / emtricitabine / tenofovir disoproxil)

Taking efavirenz with food increases the amount of medicine in your body, which may increase the frequency of side effects.

You should take efavirenz once a day on an empty stomach, preferably at bedtime.

Taking it at bedtime may make some side effects such as dizziness, trouble sleeping, drowsiness, trouble concentrating, and/or unusual dreams less bothersome. However, these symptoms may be more severe if efavirenz is used with alcohol or mood-altering (street) drugs.

You should avoid driving or operating hazardous machinery until you know how the medication affects you.

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:

tenofovir Food/Lifestyle

Applies to: Atripla (efavirenz / emtricitabine / tenofovir disoproxil)

Food may affect the absorption of tenofovir.

You should take tenofovir alafenamide products with food. Tenofovir disoproxil fumarate tablets may be taken with or without food, although some authorities recommend taking them with food. If you are using tenofovir disoproxil fumarate oral powder or granules, mix tenofovir with soft food and take it with food.

Follow the directions on your prescription label and talk to your doctor or pharmacist if you have questions about how to take tenofovir.

Take tenofovir regularly and avoid missing doses, since missed doses may make the medication less effective and may lead to drug resistance.

Disease interactions

21 potential interactions Applies to: 15 conditions, including Depression, Vitamin D Deficiency, Osteoporosis, Seizures, and Hypotension.

Alcoholism

Major:

Atripla

The tenofovir in Atripla has a major potential interaction with Alcoholism.

Hepatotoxicity including lactic acidosis, severe hepatomegaly with steatosis, fulminant hepatitis, and hepatic failure has been associated with the use of some nucleoside reverse transcriptase inhibitors (NRTIs) alone or in combination with other antiretroviral agents. Therapy with NRTIs should be administered cautiously in patients with preexisting liver disease, a history of alcohol abuse, or hepatitis. Therapy should be suspended if clinical or laboratory findings suggestive of lactic acidosis or pronounced hepatotoxicity occur. The use of abacavir is contraindicated in patients with moderate to severe liver dysfunction as its safety and efficacy have not been established in these patients.

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.

Moderate:

Atripla

The efavirenz in Atripla has a moderate potential interaction with Alcoholism.

During clinical trials, efavirenz was associated with an increase in the occurrence of serious psychiatric events, including severe depression, suicidal ideation, nonfatal suicide attempts, aggressive behavior, paranoid reactions, and manic reactions. Other factors associated with an increased occurrence of these psychiatric symptoms were history of injectable drug use, psychiatric history, or use of psychiatric medications at study entry; similar associations were observed in the efavirenz and control groups. Therapy with efavirenz should be administered cautiously in patients with current/history of psychiatric illness, emotional instability, or substance abuse. Patients with serious psychiatric adverse reactions should receive prompt medical evaluation to assess the possibility that symptoms are related to efavirenz use, and if so, to determine whether the risks of continued therapy outweigh the benefits.

Depression

Moderate:

Atripla

The efavirenz in Atripla has a moderate potential interaction with Depression.

During clinical trials, efavirenz was associated with an increase in the occurrence of serious psychiatric events, including severe depression, suicidal ideation, nonfatal suicide attempts, aggressive behavior, paranoid reactions, and manic reactions. Other factors associated with an increased occurrence of these psychiatric symptoms were history of injectable drug use, psychiatric history, or use of psychiatric medications at study entry; similar associations were observed in the efavirenz and control groups. Therapy with efavirenz should be administered cautiously in patients with current/history of psychiatric illness, emotional instability, or substance abuse. Patients with serious psychiatric adverse reactions should receive prompt medical evaluation to assess the possibility that symptoms are related to efavirenz use, and if so, to determine whether the risks of continued therapy outweigh the benefits.

Drug Dependence

Moderate:

Atripla

The efavirenz in Atripla has a moderate potential interaction with Drug Dependence.

During clinical trials, efavirenz was associated with an increase in the occurrence of serious psychiatric events, including severe depression, suicidal ideation, nonfatal suicide attempts, aggressive behavior, paranoid reactions, and manic reactions. Other factors associated with an increased occurrence of these psychiatric symptoms were history of injectable drug use, psychiatric history, or use of psychiatric medications at study entry; similar associations were observed in the efavirenz and control groups. Therapy with efavirenz should be administered cautiously in patients with current/history of psychiatric illness, emotional instability, or substance abuse. Patients with serious psychiatric adverse reactions should receive prompt medical evaluation to assess the possibility that symptoms are related to efavirenz use, and if so, to determine whether the risks of continued therapy outweigh the benefits.

Hemodialysis

Moderate:

Atripla

The emtricitabine in Atripla has a moderate potential interaction with Hemodialysis.

Emtricitabine is removed by hemodialysis. When started within 1.5 hours of emtricitabine dosing, about 30% of the dose was removed over a 3-hour hemodialysis session (blood flow rate of 400 mL/min and a dialysate flow rate of 600 mL/min). If dosing on day of hemodialysis, emtricitabine should be administered after hemodialysis.

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.

Infectious Hepatitis

Major:

Atripla

The emtricitabine and tenofovir in Atripla both have a major potential interaction with Infectious Hepatitis.

Severe acute exacerbations of HBV have been reported in HIV-1/HBV-coinfected patients who have discontinued products containing emtricitabine, lamivudine, and/or tenofovir disoproxil fumarate (DF) and may occur with discontinuation of tenofovir alafenamide-containing products. It is recommended that all patients with HIV-1 infection be tested for the presence of HBV before or when initiating products containing emtricitabine, lamivudine, tenofovir DF, or tenofovir alafenamide. Hepatic function should be monitored closely with both clinical and laboratory follow-up for at least several months in HIV-1/HBV-coinfected patients who discontinue products (including fixed-dose combination products) that contain emtricitabine, lamivudine, tenofovir DF, or tenofovir alafenamide. If appropriate, initiation or resumption of antihepatitis B therapy may be warranted, especially in patients with advanced liver disease or cirrhosis since posttreatment exacerbation of hepatitis may lead to hepatic decompensation and liver failure.

Liver Disease

Major:

Atripla

The tenofovir in Atripla has a major potential interaction with Liver Disease.

Hepatotoxicity including lactic acidosis, severe hepatomegaly with steatosis, fulminant hepatitis, and hepatic failure has been associated with the use of some nucleoside reverse transcriptase inhibitors (NRTIs) alone or in combination with other antiretroviral agents. Therapy with NRTIs should be administered cautiously in patients with preexisting liver disease, a history of alcohol abuse, or hepatitis. Therapy should be suspended if clinical or laboratory findings suggestive of lactic acidosis or pronounced hepatotoxicity occur. The use of abacavir is contraindicated in patients with moderate to severe liver dysfunction as its safety and efficacy have not been established in these patients.

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:

Atripla

The efavirenz in Atripla has a moderate potential interaction with Liver Disease.

Efavirenz is not recommended for patients with moderate or severe liver dysfunction; insufficient data are available to determine whether dose adjustment is needed. Patients with mild liver dysfunction may receive efavirenz without dose adjustment. Due to extensive CYP450-mediated metabolism and limited clinical experience in patients with liver dysfunction, therapy with efavirenz should be administered cautiously in patients with mild liver dysfunction; careful monitoring is recommended for these patients. In addition, postmarketing cases of hepatitis (including fulminant hepatitis progressing to liver failure requiring transplantation or resulting in death) have occurred during therapy with efavirenz; reports have included patients with underlying liver disease (including coinfection with hepatitis B or C). Monitoring of liver enzymes before and during therapy is recommended for all patients.

Moderate:

Atripla

The tenofovir in Atripla has a moderate potential interaction with Liver Disease.

Tenofovir alafenamide (as a single ingredient product) is not recommended in patients with decompensated liver dysfunction (Child-Pugh B or C); safety and efficacy have not been established in these patients. No dose adjustment of tenofovir alafenamide is required in patients with mild liver dysfunction (Child-Pugh A).
-Combination products containing tenofovir alafenamide have not been studied in patients with severe liver dysfunction; some of these products are not recommended for use in such patients. No dose adjustment of tenofovir alafenamide-containing products is required in patients with mild or moderate liver dysfunction (Child-Pugh A or B).

The pharmacokinetics of tenofovir after a single 300 mg dose of tenofovir disoproxil fumarate (DF) have been studied in non-HIV infected subjects with moderate to severe liver dysfunction. There were no significant changes in tenofovir pharmacokinetics in subjects with liver dysfunction compared to those with normal liver function. No adjustment in tenofovir DF dosing is required in patients with liver dysfunction.

Long QT Syndrome

Moderate:

Atripla

The efavirenz in Atripla has a moderate potential interaction with Long QT Syndrome.

QTc prolongation has been observed with the use of efavirenz. Alternatives to efavirenz should be considered when administered to patients at higher risk of torsade de pointes or when coadministered with a medication with known risk of torsade de pointes.

Osteoporosis

Moderate:

Atripla

The tenofovir in Atripla has a moderate potential interaction with Osteoporosis.

In clinical trials, tenofovir disoproxil fumarate (DF) was associated with slightly greater reductions in bone mineral density (BMD) and increases in biochemical markers of bone metabolism, suggesting increased bone turnover relative to comparators. The effects of tenofovir DF-associated changes in BMD and biochemical markers on long-term bone health and future fracture risk have not been established. Calcium and vitamin D supplementation may be beneficial; however, the effect of such supplementation was not studied. Assessment of BMD should be considered for patients with history of pathologic bone fracture or other risk factors for osteoporosis or bone loss. If bone abnormalities are suspected, appropriate consultation should be obtained.

Psychiatric Disorders

Moderate:

Atripla

The efavirenz in Atripla has a moderate potential interaction with Psychiatric Disorders.

During clinical trials, efavirenz was associated with an increase in the occurrence of serious psychiatric events, including severe depression, suicidal ideation, nonfatal suicide attempts, aggressive behavior, paranoid reactions, and manic reactions. Other factors associated with an increased occurrence of these psychiatric symptoms were history of injectable drug use, psychiatric history, or use of psychiatric medications at study entry; similar associations were observed in the efavirenz and control groups. Therapy with efavirenz should be administered cautiously in patients with current/history of psychiatric illness, emotional instability, or substance abuse. Patients with serious psychiatric adverse reactions should receive prompt medical evaluation to assess the possibility that symptoms are related to efavirenz use, and if so, to determine whether the risks of continued therapy outweigh the benefits.

Psychosis

Moderate:

Atripla

The efavirenz in Atripla has a moderate potential interaction with Psychosis.

During clinical trials, efavirenz was associated with an increase in the occurrence of serious psychiatric events, including severe depression, suicidal ideation, nonfatal suicide attempts, aggressive behavior, paranoid reactions, and manic reactions. Other factors associated with an increased occurrence of these psychiatric symptoms were history of injectable drug use, psychiatric history, or use of psychiatric medications at study entry; similar associations were observed in the efavirenz and control groups. Therapy with efavirenz should be administered cautiously in patients with current/history of psychiatric illness, emotional instability, or substance abuse. Patients with serious psychiatric adverse reactions should receive prompt medical evaluation to assess the possibility that symptoms are related to efavirenz use, and if so, to determine whether the risks of continued therapy outweigh the benefits.

Renal Dysfunction

Moderate:

Atripla

The tenofovir in Atripla has a moderate potential interaction with Renal Dysfunction.

Tenofovir is primarily eliminated by the kidneys via glomerular filtration and active tubular secretion. Serum creatinine, estimated CrCl, urine glucose, and urine protein should be assessed in all patients before/when starting tenofovir (alafenamide or disoproxil fumarate [DF]) and during therapy when clinically appropriate. Serum phosphorus should also be assessed in patients with chronic kidney disease.

Postmarketing cases of renal impairment (including acute renal failure, proximal renal tubulopathy, and Fanconi syndrome) have been reported with tenofovir alafenamide-containing products; most cases had potential confounders that may have contributed to the reported renal events and may have predisposed patients to tenofovir-related side effects. Tenofovir alafenamide should be discontinued in patients who develop clinically significant decreases in renal function or evidence of Fanconi syndrome.

Renal impairment (including acute renal failure and Fanconi syndrome) has been reported with tenofovir DF. Close monitoring of renal function and dosing interval adjustment are recommended for all patients with CrCl less than 50 mL/min. Creatinine clearance should be calculated in all patients before starting tenofovir treatment and during treatment when clinically appropriate. Routine monitoring of serum creatinine and phosphorus is recommended for patients at risk of or with a history of renal dysfunction. Safety and efficacy have not been evaluated in patients with renal dysfunction using dose adjustments; therefore, the benefit of tenofovir DF treatment should be weighed against the risk of renal toxicity. Renal function should be evaluated in patients at risk of renal dysfunction who have persistent or worsening bone pain, pain in extremities, fractures, and/or muscular pain or weakness (may be indicators of proximal renal tubulopathy).

Moderate:

Atripla

The emtricitabine in Atripla has a moderate potential interaction with Renal Dysfunction.

Emtricitabine is primarily eliminated by the kidney. Dosage adjustment of emtricitabine is recommended for patients with CrCl below 50 mL/min or in patients with ESRD requiring dialysis, in accordance with the manufacturer product information. Clinical response to treatment and renal function should be closely monitored.

Seizures

Moderate:

Atripla

The efavirenz in Atripla has a moderate potential interaction with Seizures.

Convulsions have been observed in adult and pediatric patients receiving efavirenz, generally in the presence of known medical history of seizures. Caution should be taken with any patient with history of seizures. Anticonvulsant medications primarily metabolized by the liver (e.g., phenytoin, phenobarbital) may require periodic monitoring of plasma levels.

Syncope

Major:

flibanserin

Flibanserin has a major potential interaction with Syncope.

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.

Vitamin D Deficiency

Moderate:

Atripla

The tenofovir in Atripla has a moderate potential interaction with Vitamin D Deficiency.

In clinical trials, tenofovir disoproxil fumarate (DF) was associated with slightly greater reductions in bone mineral density (BMD) and increases in biochemical markers of bone metabolism, suggesting increased bone turnover relative to comparators. The effects of tenofovir DF-associated changes in BMD and biochemical markers on long-term bone health and future fracture risk have not been established. Calcium and vitamin D supplementation may be beneficial; however, the effect of such supplementation was not studied. Assessment of BMD should be considered for patients with history of pathologic bone fracture or other risk factors for osteoporosis or bone loss. If bone abnormalities are suspected, appropriate consultation should be obtained.
