What is Prozac

Generic name: fluoxetine

Fluoxetine is a drug used primarily to treat depression. This drug is a group of drugs that use selective serotonin reuptake inhibitors (SSRIs), including citalopram (Celexa), paroxetine (Paxil) and sertraline (Zoloft). Fluoxetine affects neurotransmitters, the chemicals used in the nervous system to communicate with one another. Neuronal transducers are produced and distributed by the nerves and then travel and connect to the nerves. Therefore, neurotransmitters can be considered as a brain communication system. Serotonin is a neurotransmitter released by the nerves of the brain. The serotonin moves through the space between the nerves and approaches the receptors of the nerve surface, or reaches the nerves of the receptors of the nerve surface that produces it, and is released again (a process called re-admitting). Many Experts believe that imbalance among the nerves causes depression.

Fluoxetine has been released by nerve cells after blocking the absorption of a neurotransmitter, serotonin. Since absorption is an important mechanism for eliminating the released neurotransmitters and ending their actions in adjacent nerves, the absorption reduced by fluoxetine increases free serotonin, which stimulates the neural cells in the brain.

Prozac while Pregnancy

Animal studies have failed to reveal evidence of fetal harm. There are no controlled data in human pregnancy.

Results of several epidemiological studies assessing the risk of exposure of this drug in early pregnancy have been inconsistent and not provided conclusive evidence of an increased risk of congenital malformations. Some epidemiological studies suggest an increased risk of cardiovascular malformations; however, the mechanism is unknown. Overall, data suggest that the risk of having an infant with a cardiovascular defect following maternal exposure is approximately 2 in 100 compared with 1 in 100 for the general population.

Epidemiological data have suggested that the use of SSRIs, particularly in late pregnancy, may increase the risk of persistent pulmonary hypertension in the new-borns. Data are not available for SNRIs.

The results of a cohort study indicated that 30% of neonates who had prolonged exposure to SSRIs in utero experienced symptoms, in a dose- response manner, of a neonatal abstinence syndrome (e.g., tremor, gastrointestinal or sleep disturbances, hypertonicity, high-pitched cry) after birth. The authors suggest that infants exposed to SSRIs should be closely monitored for a minimum of 48 hours after birth.

Data from animal studies has shown that fluoxetine may affect sperm quality. Human case reports from some SSRIs have shown this effect to be reversible. As yet, the impact of this on human fertility has not been observed.

This drug should be used only if the potential benefit justifies the risk to the fetus, taking into account the risks of untreated depression.

Drugs that may interact with Prozac

Fluoxetine can remain in your body for several weeks after your last dose and may interact with many other medications. Before taking any medicine, tell your doctor or pharmacist if you have taken fluoxetine for 5 days.

Some of the products that may interact with this medication are: drugs that are used by some liver enzymes such as Winblastein, antiarrhythmic such as propofenone / fluconid, three-ring antidepressants such as dizapamine / imipramine, other drugs that bleed / Bruises, including anti-thrombolytic drugs clopidogrel, NSAIDs such as ibuprofen, "blood donors" such as warfarin.

The use of mono-oxidant inhibitors with drugs may be a serious (potentially fatal) supplement. Avoid taking MAO inhibitors (Isocarboccide, Linzolide, Methylene blue, Mclubbide, Phenzelin, Prokarycine, Razgally, Safin Omid, Selegiline, Tranylcypromine) during treatment with this medicine. Most MAO inhibitors should not be used for 2 weeks before and at least 5 weeks after treatment. Ask your doctor when to start or stop this medicine.

Many medicines in addition to fluoxetine may affect the rhythm of the heart (prolonged QT), including pimozide and thioridazine, among others.

Aspirin can increase the risk of bleeding when used with this drug. However, if your doctor instructed you to inject aspirin for heart attack or stroke prevention (usually at doses ranging from 81 to 325 mg per day), you should continue to use it unless your doctor tells you Instructions.

The risk of serotonin / toxicity syndrome increases if you also take other medications that increase serotonin. These include street drugs such as MDMA / ecstasy, Santoure tablets, certain antidepressants (including other SSRIs such as citalopram / popcastein, SNRIs such as doulocetine / venlafaxine), tryptophan, and the like. The risk of serotonin / toxicity syndrome may be higher when starting or increasing the dose of these drugs.

If you use other drugs that cause drowsiness including alcohol, marijuana, antihistamines (such as cytosine, diphenhydramine), sleep or anxiety drugs (such as alprazolam, diazepam, zolpidem), muscle relaxants and pain medications (such as codeine) . Check the labels for all your medications (such as allergies or coughs and colds) as they may contain ingredients that cause drowsiness. Ask your pharmacist how to use medicines properly.

This drug may encounter some medical / laboratory tests (including a brain scan for Parkinson's disease), which may produce false test results. Make sure your laboratory personnel and all your doctors know that you are using this medication.

These studies show an increased risk of suicidal ideation and behaviour through the use of antidepressants in patients over the age of 24; there is a reduction in the risk of developing antidepressants in patients aged 65 and over (as warnings and precautions, respectively).

Be careful about the deterioration and emergence of suicidal thoughts and behaviors in patients of all ages who start with anti-depressant therapy. Recommendations from families and carers about the need for careful observation and communication with the supervisor (respectively, possible warnings and actions).
