What is Fioricet Pharmacokinetics and Fioricet Side Effects ?

This combination drug product is intended as a treatment for tension headache.

It consists of a fixed combination of butalbital, acetaminophen and caffeine. The role each component plays in the relief of the complex of symptoms known as tension headache is incompletely understood.

Pharmacokinetics

The behavior of the individual components is described below.

Butalbital

Butalbital is well absorbed from the gastrointestinal tract and is expected to distribute to most tissues in the body. Barbiturates in general may appear in breast milk and readily cross the placental barrier. They are bound to plasma and tissue proteins to a varying degree and binding increases directly as a function of lipid solubility.

Elimination of butalbital is primarily via the kidney (59% to 88% of the dose) as unchanged drug or metabolites. The plasma half-life is about 35 hours. Urinary excretion products include parent drug (about 3.6% of the dose), 5-isobutyl-5-(2,3-dihydroxypropyl) barbituric acid (about 24% of the dose), 5-allyl-5 (3-hydroxy-2-methyl-1-propyl) barbituric acid (about 4.8% of the dose), products with the barbituric acid ring hydrolyzed with excretion of urea (about 14% of the dose), as well as unidentified materials. Of the material excreted in the urine, 32% is conjugated.

The in vitro plasma protein binding of butalbital is 45% over the concentration range of 0.5 to 20 mcg/mL. This falls within the range of plasma protein binding (20% to 45%) reported with other barbiturates such as phenobarbital, pentobarbital, and secobarbital sodium. The plasma-to-blood concentration ratio was almost unity, indicating that there is no preferential distribution of butalbital into either plasma or blood cells (See OVERDOSAGE for toxicity information).

Acetaminophen

Acetaminophen is rapidly absorbed from the gastrointestinal tract and is distributed throughout most body tissues. The plasma half-life is 1.25 to 3 hours, but may be increased by liver damage and following overdosage. Elimination of acetaminophen is principally by liver metabolism (conjugation) and subsequent renal excretion of metabolites. Approximately 85% of an oral dose appears in the urine within 24 hours of administration, most as the glucuronide conjugate, with small amounts of other conjugates and unchanged drug.

Caffeine

Like most xanthines, caffeine is rapidly absorbed and distributed in all body tissues and fluids, including the CNS, fetal tissues, and breast milk.

Caffeine is cleared through metabolism and excretion in the urine. The plasma half-life is about 3 hours. Hepatic biotransformation prior to excretion, results in about equal amounts of 1-methylxanthine and 1-methyluric acid. Of the 70% of the dose that is recovered in the urine, only 3% is unchanged drug.

Drug Abuse And Dependence

Abuse And Dependee

Butalbital

Barbiturates may be habit-forming: Tolerance, psychological dependence, and physical dependence may occur especially following prolonged use of high doses of barbiturates. The average daily dose for the barbiturate addict is usually about 1500 mg. As tolerance to barbiturates develops, the amount needed to maintain the same level of intoxication increases; tolerance to a fatal dosage, however, does not increase more than two-fold. As this occurs, the margin between an intoxication dosage and fatal dosage becomes smaller. The lethal dose of a barbiturate is far less if alcohol is also ingested. Major withdrawal symptoms (convulsions and delirium) may occur within 16 hours and last up to 5 days after abrupt cessation of these drugs. Intensity of withdrawal symptoms gradually declines over a period of approximately 15 days. Treatment of barbiturate dependence consists of cautious and gradual withdrawal of the drug. Barbiturate-dependent patients can be withdrawn by using a number of different withdrawal regimens. One method involves initiating treatment at the patient’s regular dosage level and gradually decreasing the daily dosage as tolerated by the patient.

Fioricet Warnings and The Fioricet ‘High’ and Abuse

Fioricet is a prescription medication used to relieve tension headaches. It works by relaxing muscle contractions that can result in mild to moderate head pain.

The Food and Drug Administration (FDA) approved Fioricet in 1984. Novartis Pharmaceuticals was the original manufacturer. In 2003, Watson Pharmaceuticals bought the rights to Fioricet (Watson is now known as Actavis).

Fioricet is currently available from many manufacturers as a generic.

The original formulation of Fioricet included 50 milligrams (mg) of butalbital, 40 mg of caffeine, and 325 mg of acetaminophen.

However, in 2011 the FDA asked makers of prescription combination drugs with acetaminophen to limit the amount of that drug to no more than 325 mg in each tablet by 2014. This action was taken to protect consumers from severe liver damage, a risk linked with taking too much acetaminophen.

Today Fioricet includes 320 mg of acetaminophen, though some versions of the product sold online still have 325 mg.

The Fioricet ‘High’ and Abuse

The butalbital in Fioricet belongs to a class of drugs called barbiturates, a central nervous system depressant. Like other barbiturates, it has the potential to cause physical and psychological dependence, which can lead to abuse.

Those who use too much Fioricet may report feeling so relaxed and stress-free that they seek out the drug as a way to get high. Some describe it as feeling intoxicated. However, users can feel depressed and “crash” once the effects wear off.

Fioricet with Codeine

Another formula, Fioricet with codeine, is also made by Actavis to treat tension headaches. It contains 30 mg of codeine in addition to the other three drugs, and has an increased acetaminophen dose of 325 mg.

Fioricet with codeine carries a black-box warning about liver toxicity, and about the risk of respiratory problems and death in children caused by codeine.

Fioricet Warnings

Fioricet carries a black-box warning cautioning users about the link of acetaminophen to acute liver failure. In some cases, users of Fioricet have needed a liver transplant; in other cases, use of Fioricet has proven fatal.

Most problems have occurred with an acetaminophen dose of more than 4,000 mg a day. Those affected are often taking more than one product containing acetaminophen at the same time or have underlying liver disease.

Another caution concerns butalbital, which may be habit-forming and therefore has the potential to be abused.

Those with a condition known as porphyria, a rare hereditary blood disorder, should not use Fioricet.

Fioricet Withdrawal and Pain Pills?

Fioricet Withdrawal and discomfort Pills?
I have been getting Fioricet with codeine for the past year or so for my every day Migraines/Headaches.

My doctor reduce me off from the medication all of a sudden. I went through the particular withdrawal symptoms that I have been reading about. I did not want to call my Dr . about it, because I did not want him to get me personally back on it to try and taper off of it. I thought that I got that much without tapering off and I wanted to be off of all of them and never take them again. we wasn’t taking a lot of the particular medicine. Maybe 2-3 per day, if needed (I has been reading about people who get about 30 per day.. ) I was vomiting and using the bathroom a lot, I guess so the medication can get out of my program.

I got so dehydrated, we went to Urgent Care and they gave me an IV and some Tylenol 3 and Percocets for the Migraine pain I was having during the withdrawals. we took a percocet when I got home and I has been finally able to fall asleep.. I am wondering if I was getting withdrawals from the Butalbital or the Codeine in the Firoicet?? we stopped taking the Fioricet over a week ago.

I am sensation better. I took two Tylenol 3s a few days back for a bad headache. we haven’t had any given that.

I feel okay, no withdrawals at all. I am thinking it was the Butalbital I was depending on, and not the codeine….? furthermore, I just went through all of this…. I just found out that I need nose Surgery in about a 30 days and a half. Now, I know that they will be giving me discomfort pills for the recovery (probably Percocets or Vicodin), we don’t want to fall back into what I just went through.

we doubt I will, because these discomfort Pills are different ingredients compared to what I taking for over a year (Fioricet). Is the Butalbital more difficult to withdrawal from than the Codeine that is in Fioricet?

Addiction is a disease that impacts your behavior because your brain is pushing you toward continuing to use the drug that triggered the reward response again and again.

Addiction to opioids is difficult to escape from, and it can lead to overdose and death. Another element of the use of opioids is tolerance and dependence. While these aren’t the same as addiction, these scenarios often go hand in hand with one another.

An opioid tolerance means that your body has become somewhat immune to the effects of these drugs so that you require higher doses to feel anything. A physical dependence means that in many ways the presence of opioids has become your new normal.

If you suddenly stop using opioids when you’re physically dependent on them, whether or not you’re addicted, you may experience very uncomfortable symptoms which are categorized as withdrawal. Some of the symptoms of opiate withdrawal can include nausea, vomiting, goose bumps, cramping, diarrhea, agitation, anxiety, insomnia, and yawning. Withdrawal from opioids can range from annoying to very painful. During a medically-supervised opioid detox, doctors can prescribe certain medicines that can help keep the person more comfortable and help them be more successful at stopping their use of the drugs.

Some of the medicines that may be given to patients during opiate withdrawal include methadone, buprenorphine, clonidine, and naltrexone. These drugs do everything from providing a maintenance system for opioid addicts, to helping with the actual symptoms such as muscle aches and anxiety.

Some people may attempt to manage their own withdrawal from opioids, and not only can this be dangerous, but it is also often ineffective.

Codeine will be worse. I take Vicodin 2 & 4 a day depending on how i feel. Percocet and Vicodin are both drugs. I started on seven. /500 then went to 10/500 mg. Oh yea them great ole withdraws. Take Care.

What should I avoid while taking Fioricet?

This medication can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.

Avoid drinking alcohol. It may increase your risk of liver damage while taking acetaminophen.

Ask a doctor or pharmacist before using any other cold, allergy, pain, or sleep medication. Acetaminophen (sometimes abbreviated as APAP) is contained in many combination medicines. Taking certain products together can cause you to get too much acetaminophen which can lead to a fatal overdose. Check the label to see if a medicine contains acetaminophen or APAP.

While you are taking this medication, avoid taking diet pills, caffeine pills, or other stimulants (such as ADHD medications) without your doctor’s advice.
