What is Prozac?
Prozac is part of the selective serotonin reuptake inhibitors (SSRIs) family of medications.
It has multiple treatment uses, including: depression, bulimia, and Obsessive-Compulsive Disorder (OCD).
For more resources, including a full list of the risks and benefits of Prozac, please review the product monograph.
How does Prozac work?
Although the exact mechanism of Prozac’s function is still being explored, it’s believed that it works by increasing the levels of serotonin in the brain.
In turn, this helps reduce the symptoms associated with mental health conditions like depression, bulimia, and OCD.
What is Prozac used to treat?
Prozac currently has three conditions that it’s indicated for use as a treatment. These are:
1. Depression
2. Bulimia
3. Obsessive-Compulsive Disorder (OCD)
Prozac has been shown to reduce the severity of symptoms that are associated with these conditions.
How do you take Prozac?
Prozac is to be taken orally, with or without food. It’s important to note that the capsules should not be opened or chewed, they’re to be swallowed whole.
Dosages may vary depending on your individual needs, and the recommendations made by your healthcare practitioner.
It’s vital that you follow your dosing instructions exactly as instructed by your practitioner. If you miss a dose, the recommendation is to take the missed dose as soon as you remember, and then take the next one at its regularly scheduled time.
Don’t stop taking Prozac without first consulting with your healthcare practitioner, because stopping the medication suddenly can cause negative side effects (i.e., headache, numbness, insomnia, etc.).
It may take weeks to start and notice changes from the medication, so it’s important to maintain regular dosages. Otherwise, it may not function as effectively as possible. Keep taking your Prozac until your doctor tells you to stop.
Remember: this medicine has been prescribed only for you. Do not give it to anybody else, as they may experience undesirable effects that can be serious.
