Drug interactions between Fiorinal and Norco
Interactions between your drugs
butalbital ↔ hydrocodone
Applies to:Fiorinal (aspirin/butalbital/caffeine) and Norco (acetaminophen/hydrocodone)
Using HYDROcodone 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 HYDROcodone in some cases, which may make the medication less effective in treating your condition. If you have been receiving treatment with HYDROcodone, 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 HYDROcodone, 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.
acetaminophen ↔ butalbital
Applies to:Norco (acetaminophen/hydrocodone) and Fiorinal (aspirin/butalbital/caffeine)
Using acetaminophen together with butalbital may alter the effects of acetaminophen and cause serious side effects that may affect your liver. Call your doctor immediately if you experience a fever, chills, joint pain or swelling, excessive tiredness or weakness, unusual bleeding or bruising, skin rash or itching, loss of appetite, nausea, vomiting, or yellowing of the skin or the whites of your eyes. If your doctor does prescribe these medications together, you may need a dose adjustment or special tests to safely take both medications. 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.
