Cymbalta – Duloxetine uses, dose and side effects

}

30 mg, 60 mg hard enteric capsules 
Duloxetine (as hydrochloride)

1. What Cymbalta is and what it is used for

Cymbalta contains the active substance duloxetine. Cymbalta increases the amount of serotonin and norepinephrine in the nervous system.

Cymbalta is used in adults to treat:

  • Depression
  • generalized anxiety disorder (constant feeling of anxiety or worry)
  • painful diabetic neuropathy (usually described as burning, stinging, stinging, stabbing, or aching pain or as an electric shock. Pain can be caused by touch, heat, cold, or pressure but the affected area can also be completely numb).

In most people with depression or anxiety, Cymbalta starts working within two weeks of starting treatment, but it may take 2-4 weeks before you feel better. Talk to your doctor if you do not start to feel better after this time. Your doctor may continue to give you Cymbalta even when you are feeling better to prevent recurrence of depression or anxiety.

For most people who have painful diabetic neuropathy, it can take a few weeks before they feel better. Talk to your doctor if you do not feel better after 2 months.

If you suffer from any of the following, Cymbalta may not be right for you. Talk to your doctor before taking Cymbalta if you:

  • taking other medicines for depression (see “Other medicines and CymbaltaALTA”)

  • while being treated with another medicine that may cause liver damage
  • take other medicines that contain duloxetine (see “Other medicines and Cymbalta”).

Cymbalta can cause a feeling of restlessness and difficulty sitting or standing still. If this happens, tell your doctor.

Drugs such as Cymbalta (so-called SSRIs / SNRIs) can cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms persist after discontinuation of treatment.

If you start to feel worse and have thoughts of harming yourself

You who are depressed and/or suffer from worry/anxiety may sometimes have thoughts of harming yourself or committing suicide. These symptoms may worsen when you start using antidepressants, as it takes time for this type of medicine to take effect, usually about 2 weeks, sometimes longer.

These thoughts may be common if you:

– have previously had thoughts of harming yourself or committing suicide,

– is younger than 25 years. Studies have shown that young adults (younger than 25 years) with mental illness who are treated with antidepressant drugs have an increased risk of suicidal thoughts and thoughts of harming themselves.

Drugs such as Cymbalta (so-called SSRIs / SNRIs) can cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms persist after discontinuation of treatment.

Contact a doctor as soon as possible or see the nearest hospital if you have thoughts of injuring yourself or committing suicide.

It may be helpful to tell a relative or close friend that you are depressed and/or suffering from anxiety. Feel free to ask them to read this leaflet. You can also ask them to tell you if they think you are feeling worse or if they think your behavior is changing.

Children and young people under 18 years of age

Cymbalta should not normally be used in the treatment of children and adolescents under 18 years of age. The risk of side effects such as suicide attempts, suicidal thoughts, and hostility (mainly aggression, defiance, and anger) is greater in patients under 18 years of age when taking this type of drug. Nevertheless, Cymbalta can be prescribed by a doctor to patients under 18 years of age if the doctor deems it appropriate. If you are under 18 years of age and want to discuss why you were given this medicine, consult your doctor again. You should also tell your doctor if you notice any of the above symptoms or if they get worse. Also, the long-term effects on growth, maturity, and development of intellect and behavior have not yet been determined for this age group.

Cymbalta with food, drink, and alcohol

Cymbalta can be taken regardless of the meal. You should be careful with alcohol during treatment with Cymbalta.

Pregnancy and breastfeeding

  • If you are pregnant or breast-feeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
  • Tell your doctor if you become pregnant or plan to become pregnant during treatment with Cymbalta. You should only use Cymbalta after consulting your doctor regarding the possible benefits of the treatment and any possible risks to the fetus.
  • Tell your midwife or doctor that you are taking Cymbalta. When similar drugs ( SSRIs ) are used during pregnancy, the risk of a serious condition called persistent pulmonary hypertension in the newborn (PPHN) may increase. This condition causes the baby to breathe faster and look blue. The symptoms usually appear within 24 hours of the baby being born.
  • If this affects your baby, contact a midwife or doctor immediately. If you take Cymbalta at the end of your pregnancy, your baby may experience some postpartum symptoms. These symptoms usually occur at birth or within a few days after your baby is born. Symptoms may include weak muscles, tremors, tremors, difficulty feeding, breathing problems, and seizures. If your newborn baby has any of these symptoms, or if you are concerned about your baby’s health, you should contact your doctor or midwife for advice.
  • If you take Cymbalta at the end of your pregnancy, there is an increased risk of severe vaginal bleeding shortly after delivery, especially if you have previously had bleeding disorders. Your doctor or midwife should tell you to take duloxetine so that they can give you advice.
  • Available data from the use of Cymbalta during the first three months of pregnancy do not indicate a generally increased risk of birth defects in the baby. If Cymbalta is taken during the second half of pregnancy, there may be an increased risk of the baby being born prematurely (6 extra premature babies per 100 women taking Cymbalta during the second half of pregnancy), usually between weeks 35 and 36 of the pregnancy.
  • Tell your doctor if you are breast-feeding. The use of Cymbalta during breast-feeding is not recommended. Consult your doctor or pharmacist.
