What is Cymbalta

Cymbalta is used to treat major depressive disorder in adults. It is also used to treat general anxiety disorder in adults and children who are at least 7 years old.

Cymbalta is also used in adults to treat fibromyalgia (a chronic pain disorder), or chronic muscle or joint pain (such as low back pain and osteoarthritis pain).

Cymbalta is also used to treat pain caused by nerve damage in adults with diabetes (diabetic neuropathy).

Duloxetine is used to treat depression and anxiety. Duloxetine may improve your mood, sleep, appetite, and energy level, and decrease nervousness. It can also decrease pain due to certain medical conditions. 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.

In addition, duloxetine is used to help relieve nerve pain (peripheral neuropathy) in people with diabetes or ongoing pain due to medical conditions such as arthritis, chronic back pain, or fibromyalgia (a condition that causes widespread pain).

Duloxetine hydrochloride is a white to slightly brownish white solid, which is slightly soluble in water.

Cymbalta (Duloxetine) is a selective serotonin and norepinephrine reuptake inhibitor antidepressant (SSNRI). Duloxetine affects chemicals in the brain that may be unbalanced in people with depression.

How to use Cymbalta

Read the Medication Guide and, if possible, the Patient Information Leaflet provided by your pharmacist before you start using duloxetine and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth as directed by your doctor, usually 1 or 2 times a day with or without food. If you have nausea, it may help to take this drug with food. Swallow the capsule whole. Do not crush or chew the capsule or mix the contents with food or liquid. Doing so can release all of the drug at once, increasing the risk of side effects.

The dosage is based on your age, medical situation and response to treatment. To reduce your risk of side effects, your doctor may direct you to start this medication at a low dose and gradually increase your dose. Follow your doctor's instructions carefully. Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day.

Tell your doctor if your condition persists or gets worse.

Swallow CYMBALTA whole. Do not chew or crush. Do not open the capsule and sprinkle its contents on food or mix with liquids. All of these might affect the enteric coating. CYMBALTA can be given without regard to meals. If a dose of CYMBALTA is missed, take the missed dose as soon as it is remembered. If it is almost time for the next dose, skip the missed dose and take the next dose at the regular time. Do not take two doses of CYMBALTA at the same time.

Take Cymbalta exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

It may take 1 to 4 weeks before your symptoms improve. Keep using the medication as directed. Do not stop using Cymbalta without first talking to your doctor. You may have unpleasant side effects if you stop taking this medicine suddenly.

Store Cymbalta at room temperature away from moisture and heat.

Dosage of Cymbalta

Dosage for Treatment of Major Depressive Disorder

Administer CYMBALTA at a total dose of 40 mg/day (given as 20 mg twice daily) to 60 mg/day (given either once daily or as 30 mg twice daily). For some patients, it may be desirable to start at 30 mg once daily for 1 week, to allow patients to adjust to the medication before increasing to 60 mg once daily. While a 120 mg/day dose was shown to be effective, there is no evidence that doses greater than 60 mg/day confer any additional benefits. The safety of doses above 120 mg/day has not been adequately evaluated. Periodically reassess to determine the need for maintenance treatment and the appropriate dose for such treatment.

Side effects of Cymbalta

Nausea, dry mouth, constipation, loss of appetite, tiredness, drowsiness, or increased sweating may occur. If any of these effects persist or worsen, tell your doctor promptly.

Dizziness or lightheadedness may occur, especially when you first start or increase your dose of this drug. To reduce the risk of dizziness, lightheadedness, or falling, get up slowly when rising from a sitting or lying position.

This medication may raise your blood pressure. Check your blood pressure regularly and tell your doctor if the results are not normal.

Tell your doctor right away if any of these serious side effects occur: confusion, easy bruising/bleeding, decreased interest in sex, changes in sexual ability, muscle cramps/weakness, shaking (tremor), difficulty urinating, signs of liver problems (such as stomach/abdominal pain, persistent nausea, vomiting, yellowing eyes/skin, dark urine).

Drugs that may interact to Cymbalta

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's confirmation.

Some products that may interact with this drug include: other drugs that can cause bleeding/bruising (including antiplatelet drugs such as clopidogrel, NSAIDs such as ibuprofen, "blood thinners" such as warfarin).

Other medications can affect the removal of duloxetine from your body, which may affect how duloxetine works. Examples include cimetidine, certain quinolone antibiotics (such as ciprofloxacin, enoxacin), among others.

This medication can slow down the removal of other medications from your body, which may affect how they work. Examples of affected drugs include antiarrhythmic drugs (such as propafenone, flecainide, quinidine), antipsychotics (such as thioridazine), tricyclic antidepressants (such as desipramine, imipramine), among others.

The risk of serotonin syndrome/toxicity increases if you are also taking other drugs that increase serotonin. Examples include street drugs such as MDMA/"ecstasy," St. John's wort, certain antidepressants (including SSRIs such as fluoxetine/paroxetine, other SNRIs such as desvenlafaxine/venlafaxine), tryptophan, among others. The risk of serotonin syndrome/toxicity may be more likely when you start or increase the dose of these drugs.

Tell your doctor if you are taking other products that cause drowsiness including alcohol, marijuana, antihistamines (such as cetirizine, diphenhydramine), drugs for sleep or anxiety (such as alprazolam, diazepam, zolpidem), muscle relaxants, and narcotic pain relievers (such as codeine). Check the labels on all your medicines (such as allergy or cough-and-cold products) because they may contain ingredients that cause drowsiness. Ask your pharmacist about using those products safely.

Aspirin can increase the risk of bleeding when used with this medication. However, if your doctor has directed you to take low-dose aspirin for heart attack or stroke prevention (usually at dosages of 81-325 milligrams a day), you should continue taking it unless your doctor instructs you otherwise.

Many drugs can interact with duloxetine. Not all possible interactions are listed here. Tell your doctor about all your current medicines and any you start or stop using, especially:

any other antidepressant;

theophylline;

tryptophan (sometimes called L-tryptophan);

an amphetamine - Adderall, Focalin, Vyvanse, Ritalin, Concerta, Strattera, and others;

an antibiotic - ciprofloxacin, enoxacin;

a blood thinner - warfarin, Coumadin, Jantoven;

heart rhythm medication - flecainide, propafenone, quinidine, and others;

opioid medicine - fentanyl, tramadol;

medicine to treat mood disorders, thought disorders, or mental illness - buspirone, lithium, thioridazine, and many others; or

migraine headache medicine - sumatriptan, rizatriptan, zolmitriptan, and others.

For whom Cymbalta might not be safe

Older adults may be more sensitive to the side effects of this drug, especially bleeding, dizziness, lightheadedness, or loss of coordination. Older adults may also be more likely to develop a type of salt imbalance (hyponatremia), especially if they are taking "water pills" (diuretics). Dizziness, lightheadedness, or loss of coordination can increase the risk of falling.

Children may be more sensitive to the side effects of this drug, especially loss of appetite and weight loss. Monitor weight and height in children who are taking this drug. See also Warning.

Can you use Cymbalta while pregnancy?

In animal studies, duloxetine did not demonstrate barbiturate-like (depressant) abuse potential.

While CYMBALTA has not been systematically studied in humans for its potential for abuse, there was no indication of drug-seeking behavior in the clinical trials. However, it is not possible to predict on the basis of premarketing experience the extent to which a CNS active drug will be misused, diverted, and/or abused once marketed. Consequently, physicians should carefully evaluate patients for a history of drug abuse and follow such patients closely, observing them for signs of misuse or abuse of CYMBALTA (e.g., development of tolerance, incrementation of dose, drug-seeking behavior).

Warnings of Cymbalta

Patients with major depressive disorder (MDD), both adult and pediatric, may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking antidepressant medications, and this risk may persist until significant remission occurs. Suicide is a known risk of depression and certain other psychiatric disorders, and these disorders themselves are the strongest predictors of suicide. There has been a long-standing concern, however, that antidepressants may have a role in inducing worsening of depression and the emergence of suicidality in certain patients during the early phases of treatment.

Pooled analyses of short-term placebo-controlled trials of antidepressant drugs (SSRIs and others) showed that these drugs increase the risk of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults (ages 18-24) with major depressive disorder (MDD) and other psychiatric disorders. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction with antidepressants compared to placebo in adults aged 65 and older.
