Duloxetine is known as a serotonin-norepinephrine reuptake inhibitor (SNRI). This medication works by helping to restore the balance of certain natural substances (serotonin and norepinephrine) in the brain. Additionally, the benefit of up-titration in non-responders to CYMBALTA at 60 mg/day was evaluated in a separate trial (Study FM-3). Adult patients were initially treated with CYMBALTA 60 mg once daily for eight weeks in open-label fashion. Subsequently, completers of this phase were randomized to double-blind treatment with CYMBALTA at either 60 mg once daily or 120 mg once daily.
Response and effectiveness
The safety and effectiveness of CYMBALTA for the treatment of fibromyalgia in patients less than 13 years of age have not been established. However, fetal weights were decreased at this dose, with a no-effect dose of 10 mg/kg/day (approximately equal to the MRHD in rats and 2 times the MRHD in rabbits). Advise patients that hyponatremia has been reported as a result of treatment with SNRIs and SSRIs, including CYMBALTA. Advise patients of the signs and symptoms of hyponatremia [see WARNINGS AND PRECAUTIONS]. Advise patients to inform their healthcare provider if they have a history of seizure disorder [see WARNINGS AND PRECAUTIONS]. Caution patients that CYMBALTA may cause serious skin reactions.
- People taking Cymbalta should avoid drinking excessive amounts of alcohol.
- Depending on the amount of alcohol you consume, they may decide to have you try a different medication for your condition.
- For more information on the possible side effects of Cymbalta, talk with your doctor or pharmacist.
- In drug dependence studies, duloxetine did not demonstrate dependence-producing potential in rats.
What Are Warnings and Precautions for Duloxetine?
This means your doctor will need to get approval from your insurance company before your insurance company will pay for the prescription. You should not need a new prescription for this medication to be refilled. Your doctor will write the number of refills authorized on your prescription. General information about the safe and effective use of Cymbalta. People who take Cymbalta close in time to an MAOI may have a serious problem called Serotonin Syndrome (see “What are the possible side effects of Cymbalta?”).
General information about the safe and effective use of Cymbalta
Consideration should be given to dose reduction or discontinuation of CYMBALTA in patients who experience symptomatic orthostatic hypotension, falls and/or syncope during CYMBALTA therapy. In some cases, a patient already receiving CYMBALTA therapy may require urgent treatment with linezolid or intravenous methylene blue. alcohol intervention The patient should be monitored for symptoms of serotonin syndrome for 5 days or until 24 hours after the last dose of linezolid or intravenous methylene blue, whichever comes first. Therapy with CYMBALTA may be resumed 24 hours after the last dose of linezolid or intravenous methylene blue [see WARNINGS AND PRECAUTIONS].
Duloxetine comprises about 3% of the total radiolabeled material in the plasma, indicating that it undergoes extensive metabolism to numerous metabolites. The major biotransformation pathways for duloxetine involve oxidation of the naphthyl ring followed by conjugation and further oxidation. Both CYP1A2 and CYP2D6 catalyze the oxidation of the naphthyl ring in vitro. Metabolites found in plasma include 4-hydroxy duloxetine glucuronide and 5hydroxy, 6-methoxy duloxetine sulfate. Food does not affect the Cmax of duloxetine, but delays the time to reach peak concentration from 6 to 10 hours and it marginally decreases the extent of absorption (AUC) by about 10%. Duloxetine has an elimination half-life of about 12 hours (range 8 to 17 hours) and its pharmacokinetics are dose proportional over the therapeutic range.
Is duloxetine an SNRI, SSRI, or narcotic?
Examples include cimetidine, fluvoxamine, viloxazine, certain quinolone antibiotics (such as ciprofloxacin, enoxacin), among others. Take this medication by mouth with or without food as directed by your doctor, usually 1 or 2 times a day. You may swallow this medication whole, or you may open the capsule and sprinkle the alcohol and rage what you need to know contents on a tablespoonful of applesauce. Ask your healthcare provider for a list of these medicines if you are not sure. Examples include cimetidine, viloxazine, certain quinolone antibiotics (such as ciprofloxacin, enoxacin), among others. During pregnancy, this medication should be used only when clearly needed.
Monitor all patients taking CYMBALTA for the emergence of serotonin syndrome. Discontinue treatment with CYMBALTA and any concomitant serotonergic agents immediately if the above symptoms occur, and initiate supportive symptomatic treatment. If concomitant use of CYMBALTA with other serotonergic drugs is clinically warranted, inform patients of the increased risk for serotonin syndrome and monitor for symptoms. Table 6 provides the incidence of adverse reactions in MDD and GAD pediatric placebo-controlled trials that occurred in greater than 2% of patients treated with CYMBALTA and with an incidence greater than patients treated with placebo.
A specific caution involves patients who overdose with CYMBALTA and tricyclic antidepressants. There is no specific antidote to a CYMBALTA overdosage, but if serotonin syndrome ensues, specific treatment (such as with cyproheptadine and/or temperature control) may be considered. Patients with clinically evident hepatic impairment have decreased duloxetine metabolism and elimination. Although Cmax was similar to normals in the cirrhotic patients, the half-life was about 3 times longer [see DOSAGE AND ADMINISTRATION and WARNINGS AND PRECAUTIONS]. Neonates exposed to CYMBALTA and other SNRIs or SSRIs late in the third trimester have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding.
Lexapro belongs to a class of medications called selective serotonin reuptake inhibitors (SSRIs). SNRIs and SSRIs work in similar ways but do have differences. The recommended Cymbalta dosage for treating fibromyalgia in adults is 60 mg once per day. After a week, your doctor may increase your dosage to 60 mg once daily. Doses above 60 mg are not recommended for treating this condition.
Babies born to mothers who have used this drug during the last 3 months of pregnancy may rarely develop withdrawal symptoms such as feeding/breathing difficulties, seizures, muscle stiffness, or constant crying. If you notice early signs of liver damage from alcohol: how to tell what to know any of these symptoms in your newborn, tell the doctor promptly. When discontinuing treatment with duloxetine, the manufacturer recommends a gradual reduction in the dose, rather than abrupt cessation, whenever possible.
If you experience sleep issues while taking Cymbalta, talk with your doctor. Or they may have you try a different medication to treat your condition. While taking Cymbalta, your child’s doctor will monitor their weight to make sure it stays in a healthy range for their age.
Subsequently, over the 4-to 6-month uncontrolled extension periods, CYMBALTA-treated patients on average trended toward recovery to their expected baseline weight percentile based on population data from age-and sex-matched peers. Following is a list of adverse reactions reported by patients treated with CYMBALTA in clinical adult trials. In clinical trials of all approved adult populations, 34,756 patients were treated with CYMBALTA. Of these, 27% (9337) took CYMBALTA for at least 6 months, and 12% (4317) took CYMBALTA for at least one year.
