Is it safe to take Cymbalta if I take Fioricet(Butalbital APAP Caffeine)?

I take Fioricet(Butalbital APAP Caffeine) sometimes 3 to 4 tablets a day for migraines. I was prescribed Cymbalta for fibromyalgia. Is it safe to take these on the same day? I took one dose of Cymbalta at night and the next day was very dizzy while driving. I had taken the Fioricet(Butalbital APAP Caffeine) in the morning.

But, just phone a 24 hour pharmacy, like shoppers drug mart, and they will tell you definitively right away. It is very important your prescribing physician knows about all medications you take, even if they are herbal remedies.

Don’t forget you just started this med. So it will probably take 2-3 weeks for side effects to subside. Dizziness is a noted side effect.

I just looked up fioricet and it is a combination of a barbiturate, caffeine and acetaminophen.

You can note that Cymbalta puts a certain strain on the Liver, so the addition of other things that add a certain strain on the liver (i.e. fioricet) will make your liver work a bit. So, whether or not your liver is healthy or not and can handle this load, would have to be determined by your doctor. Hepatoxicity is the concern.

Here is an excerpt pertinent to you (specifically the barbiturate, which is a CNS depressant):
“CNS Acting medications — Given the primary CNS effects of Cymbalta, it should be used with caution when it is taken in combination with or substituted for other centrally acting drugs, including those with a similar mechanism of action [see Warnings and Precautions (5.11) and medication Interactions (7.17)].”

Excerpt pertinent to Caffeine:
“In vitro drug interaction studies demonstrate that duloxetine does not induce CYP1A2 activity. Therefore, an increase in the metabolism of CYP1A2 substrates (e.g., theophylline, caffeine) resulting from induction is not anticipated, although clinical studies of induction have not been performed. Duloxetine is an inhibitor of the CYP1A2 isoform in in vitro studies, and in two clinical studies the average (90% confidence interval) increase in theophylline AUC was 7% (1%-15%) and 20% (13%-27%) when co-administered with duloxetine (60 mg twice daily).”

In general:
5.11 Clinically Important medication Interactions
Both CYP1A2 and CYP2D6 are responsible for duloxetine metabolism.
Potential for Other medications to Affect Cymbalta
CYP1A2 Inhibitors — Co-administration of Cymbalta with potent CYP1A2 inhibitors should be avoided [see medication
Interactions (7.1)].
CYP2D6 Inhibitors — Since CYP2D6 is involved in duloxetine metabolism, concomitant use of duloxetine with
potent inhibitors of CYP2D6 would be expected to, and does, result in higher concentrations (on average of 60%) of duloxetine [see medication Interactions (7.2)].”

Another Excerpt:
“7.18 medications Highly Bound to Plasma Protein
Because duloxetine is highly bound to plasma protein, administration of Cymbalta to a patient taking another drug that is highly protein bound may cause increased free concentrations of the other drug, potentially resulting in adverse reactions. However, co-administration of duloxetine (60 or 120 mg) with warfarin (2-9 mg), a highly protein-bound drug, did not result in significant changes in INR and in the pharmacokinetics of either total S-or total R-warfarin (protein bound plus free drug) [see medication Interactions (7.4)].”

Is it safe to take fioricet while on oxycodone?

Is it safe to take fioricet while on oxycodone?
I just got my wisdom teeth out yesterday and they were bothering me so I took 3 of the 5mg oxycodones that I was prescribed. I have a migraine though and I cannot sleep. Would it be safe for me to take fioricet to help with the migraine?

Answer by John Doe
I do sometimes myself, but I wouldnt take more then one of each due to the amount of Acetaminophen.
Fioricet has 325mg of acetaminophen, and it depends on what type of oxycodone drug your on, some contain 325mg, and some have 650mg’s, or if it’s oxycontin it wont have any acetaminophen at all, just try not to ecceed more then 650 mg of acetaminophen in a 3 hour period.
