Any medication taken will have certain side effects, some people may develop side effect and majorly people don’t appear to develop any.
For any medication there is always a risk to benefit ratio that needs to be assessed.
Prozac is an SSRI, if you are responding to it and all the symptoms have been remitted, no need to restart it until recurrence of symptoms.
Binge eating or stress eating shows lack of impulse control when seen through brain functional circuits. This can be manifested in many forms like skin excoriating, anger outbursts, self harming behaviour, purging behaviour etc.
Further there are likely chances of developing anxiety or depressive features which needs to be watched.
Next Steps
As you aren’t on any medication, despite the long half life of Prozac, 1 month duration is sufficient to wash off all its effect. No issues in conceiving. Even if you keep on taking it while you are
pregnant, nothing much to worry, very less teratogenic effect noted in research. Thus benefit outweighs the risk.
Health Tips
Pregnancy itself is can precipitate psychiatric symptoms. Thus keep a close watch for any symptoms that develops and don’t hesitate to consult a psychiatrist for it.
