Drugs.com identifies the pill with the imprint "Pliva 648" as fluoxetine 20 milligrams, or Prozac. Fluoxetine is prescribed to treat depression, obsessive-compulsive disorder, certain eating disorders, panic attacks and premenstrual dysphoric disorder, states MedlinePlus. Occasionally, fluoxetine is used to treat alcoholism, attention deficit disorder, borderline personality disorder, sleep problems, headaches, post-traumatic stress disorder, Tourette syndrome, obesity, phobias and sexual problems.
MedlinePlus reveals that fluoxetine is classified as a selective serotonin reuptake inhibitor, or SSRI. Fluoxetine helps maintain mental balance in the brain by increasing the amounts of the natural substance serotonin.
Before starting fluoxetine, it is important for patients to inform their doctor of their current medications, vitamins and supplements so that drug interactions can be checked, according to MedlinePlus. Patients are also advised to tell their doctor if they are being treated with electroshock therapy or have medical conditions such as diabetes, glaucoma, liver disease or heart disease. Women should inform their doctor if they are pregnant, planning on becoming pregnant, or breastfeeding. When taken in the last months of pregnancy, fluoxetine sometimes causes problems in newborns after delivery. It is generally not recommended that adults over 65 years of age take fluoxetine on a daily basis, as other medicationsused to treat the same conditions are considered safer for these patients.
