A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
PRISTIQ is an antidepressant which belongs to a group of drugs called selective serotonin and norepinephrine reuptake inhibitors (SNRIs). This medication is used to treat depression in adults. The cause of depression is unknown, but many experts believe that it results when certain chemicals in the brain are out of balance. These chemicals, called neurotransmitters, relay messages from one brain cell to another that may become unbalanced and cause depression. PRISTIQ works by affecting the levels of two of these neurotransmitters: serotonin and norepinephrine.
It may also be used to treat other conditions as determined by your doctor.
Take PRISTIQ exactly as prescribed by your doctor. Your doctor may occasionally change your dose to obtain optimal results. Keep using this medication as directed. Tell your doctor if your symptoms do not improve after 4 weeks of treatment. Do not stop using PRISTIQ suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to stop using this medication.
PRISTIQ can be taken with or without food. Try to take the medicine at the same time each day. Swallow it whole. Breaking or opening the pill may cause too much of the drug to be released at one time.
Chemical Name DESVENLAFAXINE (des-VEN-la-FAX-een)
