Drug interactions between Fioricet and Percocet

Results for the following 2 drugs:
Fioricet (acetaminophen/butalbital/caffeine)
Percocet (acetaminophen/oxycodone)

Interactions between your drugs

Major

oxyCODONE butalbital

Applies to: Percocet (acetaminophen / oxycodone) and Fioricet (acetaminophen / butalbital / caffeine)

Using oxyCODONE together with other medications that cause central nervous system depression such as butalbital can lead to serious side effects including respiratory distress, coma, and even death. Additionally, butalbital may reduce the blood levels of oxyCODONE in some cases, which may make the medication less effective in treating your condition. If you have been receiving treatment with oxyCODONE, adding butalbital may cause you to experience unpleasant withdrawal symptoms such as watery eyes, runny nose, sneezing, yawning, excessive sweating, goose bumps, fever, chills, flushing, restlessness, irritability, anxiety, depression, pupil dilation, tremor, rapid heart beat, body aches, involuntary twitching and kicking, abdominal cramping, loss of appetite, nausea, vomiting, diarrhea, and weight loss. On the other hand, if you have been receiving both medications, discontinuing butalbital may increase the blood levels of oxyCODONE, which could lead to an overdose. 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. Do not drink alcohol or self-medicate with these medications without your doctor's approval, and do not exceed the doses or frequency and duration of use prescribed by your doctor. Also, you should avoid driving or operating hazardous machinery until you know how these medications affect 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.

Drug and food interactions

Major

oxyCODONE food

Applies to: Percocet (acetaminophen / 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.

Therapeutic duplication warnings

Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition. This can be intentional in cases where drugs with similar actions are used together for demonstrated therapeutic benefit. It can also be unintentional in cases where a patient has been treated by more than one doctor, or had prescriptions filled at more than one pharmacy, and can have potentially adverse consequences.
