Drug interactions
Moderate drug interactions
Moderate:
indinavir taurursodiol
Applies to: indinavir and sodium phenylbutyrate / taurursodiol
Taurursodiol may increase the blood levels and effects of indinavir. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. 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
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.
Moderate:
sodium phenylbutyrate Food/Lifestyle
Applies to: sodium phenylbutyrate / taurursodiol
Food may affect the absorption of sodium phenylbutyrate. A high-fat, high-calorie meal (approximately 800 to 1000 calories; 500 to 600 calories from fat, 250 calories from carbohydrate, 150 calories from protein) has been shown to reduce the absorption of sodium phenylbutyrate, although it is unknown what impact this may have on the overall effectiveness of the medication. The manufacturer recommends taking sodium phenylbutyrate before a meal or snack. This is especially important if you weigh less than 70 kg (approximately 154 pounds). Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medication without first talking to your doctor.
Disease interactions
17 potential interactions Applies to: 15 conditions, including Heart Failure, Peripheral Neuropathy, Nephrolithiasis, Diabetes Mellitus, and Gallbladder 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.
Biliary Obstruction
Moderate:
sodium phenylbutyrate / taurursodiol
The taurursodiol in sodium phenylbutyrate / taurursodiol has a moderate potential interaction with Biliary Obstruction.
Sodium phenylbutyrate-taurursodiol contains taurursodiol, a bile acid. In patients with disorders that interfere with bile acid circulation, there may be an increased risk for diarrhea and patients should be monitored appropriately. Other conditions such as pancreatic insufficiency, intestinal malabsorption, or intestinal diseases that may alter the concentration of bile acids, may also lead to decreased absorption of this drug and its components. Consider consulting with a GI specialists with experience managing these GI disorders. Patients with disorders of enterohepatic circulation (e.g., biliary infection, active cholecystitis, etc.), severe pancreatic disorders (e.g., pancreatitis), and intestinal disorders that may alter concentrations of bile acids (e.g., ileal resection, regional ileitis, etc.) were excluded from clinical studies and there is no experience in patients with these conditions. Caution is advised.
Central Nervous System Disorders
Moderate:
sodium phenylbutyrate / taurursodiol
The sodium phenylbutyrate in sodium phenylbutyrate / taurursodiol has a moderate potential interaction with Central Nervous System Disorders.
Sodium phenylbutyrate is a pro-drug and is rapidly metabolized to the active, phenylacetate. Neurotoxicity, including exacerbation of a preexisting neuropathy, has been reported with the use of intravenous phenylacetate. The acute onset and reversibility when the phenylacetate infusion was discontinued suggested a drug effect. Care should be exercised when prescribing sodium phenylbutyrate to patients at risk for neurotoxicity.
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.
Fluid Retention
Major:

The sodium phenylbutyrate in sodium phenylbutyrate / taurursodiol has a major potential interaction with Fluid Retention.
The use of sodium phenylbutyrate may cause fluid retention in patients with congestive heart failure, renal dysfunction, or sodium retention with edema. Sodium phenylbutyrate is primarily excreted by the kidney and these patients may exhibit reduced excretion. Therapy with sodium phenylbutyrate should be administered cautiously in these patients. Monitoring plasma levels of ammonia, arginine, branched-chain amino acids and serum proteins to maintain within normal limits and glutamine to less than 1000 mcmol/L is recommended.
