Interactions between your drugs
ibuprofen deutivacaftor
Applies to: ibuprofen / oxycodone, deutivacaftor / tezacaftor / vanzacaftor
Consumer information for this interaction is not currently available.
MONITOR: Coadministration with ivacaftor or deutivacaftor may increase the plasma concentrations of drugs that are substrates of the CYP450 2C9 isoenzyme. The proposed mechanism, based on in vitro data, involves decreased metabolic clearance due to inhibition of CYP450 2C9 by ivacaftor and/or deutivacaftor. The clinical relevance is unknown.
MANAGEMENT: Caution is advised when ivacaftor or deutivacaftor containing medications are used concurrently with drugs that are known CYP450 2C9 substrates, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever ivacaftor or deutivacaftor are added to or withdrawn from therapy.
Drug and food interactions
oxyCODONE food
Applies to: ibuprofen / oxycodone
Do not use alcohol or medications that contain alcohol while you are receiving treatment with oxyCODONE. This may increase nervous system side effects such as drowsiness, dizziness, lightheadedness, difficulty concentrating, and impairment in thinking and judgment. In severe cases, low blood pressure, respiratory distress, fainting, coma, or even death may occur. You may also want to avoid or limit the consumption of grapefruit and grapefruit juice, which can significantly increase the blood levels of oxycodone in some people. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. Do not use more than the recommended dose of oxyCODONE, and avoid activities requiring mental alertness such as 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 medication without first talking to your doctor.
tezacaftor food
Applies to: deutivacaftor / tezacaftor / vanzacaftor
Consumer information for this interaction is not currently available.
GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of tezacaftor, deutivacaftor, and vanzacaftor. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. In general, the effect of grapefruit juice is concentration-, dose- and preparation- dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. The risk and/or severity of serious side effects such as liver damage may be increased.
ADJUST DOSING INTERVAL: Administration with fat-containing food may increase the oral bioavailability of vanzacaftor and deutivacaftor. Administration with a fat containing meal increased vanzacaftor systemic exposure (AUC) by 4- (low-fat meal) to 6- (high-fat meal) fold. While deutivacaftor AUC increased approximately 3- (low-fat meal) to 4- (high-fat meal) fold, relative to administration in a fasting state. Tezacaftor exposure is not significantly affected by administration of fat-containing foods.
MANAGEMENT: Patients treated with tezacaftor, deutivacaftor, vanzacaftor -containing medications should avoid consumption of grapefruit juice and any food that contains grapefruit. To improve absorption, patients should be advised to take vanzacaftor and/or deutivacaftor containing medications with fat-containing foods such as eggs, avocados, nuts, meat, butter, peanut butter, cheese pizza, and whole-milk dairy products at approximately the same time of the day. A typical cystic fibrosis diet will satisfy this requirement.

ibuprofen food
Applies to: ibuprofen / oxycodone
Ask your doctor before using ibuprofen together with ethanol (alcohol). Do not drink alcohol while taking ibuprofen. Alcohol can increase your risk of stomach bleeding caused by ibuprofen. Call your doctor at once if you have symptoms of bleeding in your stomach or intestines. This includes black, bloody, or tarry stools, or coughing up blood or vomit that looks like coffee grounds. 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.
