What Is Cymbalta (Duloxetine)?
Cymbalta (Duloxetine) is an antidepressant medication of the pharmacological class of serotonin and norepinephrine reuptake inhibitors (SNRIs) that elevates serotonin and norepinephrine in the brain.1 Although its chemical structure differs from other antidepressants, it is widely used as an initial treatment option. It has side effects that are normally well tolerated by many users, so speak to your physician to see if treatment with duloxetine may be viable for you.

Duloxetine is safe and well-tolerated in older adults with recurrent major depressive disorder and relieves anxiety, depression, and pain. It is known that duloxetine can cause liver damage in people who already have liver disease or who often drink alcohol. Duloxetine, however, can also cause liver damage in people without these risk conditions. Clinical investigations showed no evidence that people taking duloxetine had an increased risk of renal failure.

Cymbalta Dosing Considerations
Certain people need special dosing considerations and modifications with duloxetine. Share your medical history with your doctor to determine that it is safe for you, particularly if you: have ever had an allergic reaction to duloxetine or any other medication, have kidney or liver issues, have a heart condition, are currently taking or have recently taken other depression medications, have glaucoma, have ever experienced a seizure or fit, have manic episodes or bipolar disorder, bruise easily; are trying to become pregnant, are already pregnant, or are breastfeeding.
Conditions that require special Cymbalta dosing considerations include:
- Liver problems: Duloxetine medication has been connected to a few cases of clinically obvious acute liver injury and transitory asymptomatic rises in blood aminotransferase levels.
- Kidney problems: Renal impairment can influence a drug’s absorption, distribution, protein binding, renal excretion, or nonrenal clearance, all of which can impact pharmacokinetics.
- Glaucoma: Your eye pressure may rise if you use duloxetine.
What to Expect When Increasing Cymbalta Dosage
The side effects of Cymbalta are typically minimal.5 These side effects of frequently include nausea, headaches, exhaustion, vertigo, and vomiting. Since they frequently subside a few weeks after the initial dosage, these reactions typically do not necessitate medical treatment.
Age, general health, and how Cymbalta interacts with the body are some variables that affect how someone may respond to the medication. After starting a Cymbalta prescription, symptoms may improve after two to four weeks. Even if you do not feel better, you should not stop taking Cymbalta abruptly because recovery may take longer.
What if I Miss a Dose of Cymbalta?
Take duloxetine exactly as directed until you talk to your doctor about changing your prescription. It is advised to take the missed dose as soon as you remember or to omit it if it is almost time for your next dose of the medication.
When they feel better, some patients think about stopping their medications before the end date. If the medicine is stopped too soon, there is a higher possibility that depression or anxiety may return. If patients want to stop taking their medicine gradually, they should talk to their doctor about a tapering dose. Due to the possibility of antidepressant discontinuation syndrome, it is not recommended to discontinue taking duloxetine right away.6 Signs of antidepressant discontinuation syndrome might be flu-like symptoms, nausea, and vomiting.
Can You Overdose on Cymbalta?
Cymbalta overdose can happen and is harmful. This frequently happens when the drug is mixed with other substances. Duloxetine usage, when combined with other drugs, might result in serious consequences. Serotonin syndrome, irregular heartbeat, and convulsions are all possible side effects of duloxetine overdose. If you believe that you or someone else has overdosed on duloxetine, it is advised that you phone 9-1-1 or go to the closest emergency room.
What Should You Do If You Take Too Much Cymbalta?

Questions to Ask Your Health Team About Cymbalta Dosage
