Prozac vs Fluoxetine: are they the same?
Prozac is a commercial brand whose active ingredient is exactly Fluoxetine. This page explains what that means in practice: where they differ (brand, manufacturer, price, available strengths), why they are clinically equivalent, and when the brand or an authorised generic is the better choice.
Are they the same?
Yes — Prozac contains Fluoxetine as its active ingredient. Talking about "Prozac" in clinical terms is the same as talking about Fluoxetine at the dose strengths 10mg, 20mg, 40mg. The differences from the authorised generic are brand, manufacturer (Eli Lilly), excipients, tablet appearance and price — not the active molecule itself.
When Prozac is used
프로작은 주요우울장애(성인 및 만 8세 이상 소아), 강박장애(만 7세 이상 소아), 신경성 폭식증, 공황장애, 월경전 불쾌장애에 승인되어 있습니다. 소아 우울증에서 강력한 근거 기반과 FDA 소아 승인을 보유한 유일한 SSRI입니다. 사라펨(Sarafem) 브랜드는 PMDD에 특화된 동일 분자를 판매합니다.
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: 플루옥세틴은 세로토닌 재흡수 수송체를 선택적으로 억제하여 시냅스 세로토닌 가용성을 증가시킵니다.
Brand or generic — which to choose?
For most patients, authorised generics of Fluoxetine are clinically equivalent substitutes for Prozac and typically cost substantially less. The practical differences are manufacturer, excipients (rarely matters except in specific sensitivities), tablet appearance and price. The brand is preferred by some patients for personal reasons or insurance coverage; the generic is the default when cost matters.
자주 묻는 질문
Is Prozac the same as Fluoxetine? ▾
Clinically yes — Prozac is the brand and Fluoxetine is its active ingredient. At equivalent doses (10mg, 20mg, 40mg) they produce the same effect. The difference is brand, manufacturer (Eli Lilly) and price.
Is generic Fluoxetine as effective as Prozac? ▾
Yes. Authorised generics of Fluoxetine must demonstrate bioequivalence to the brand. The active substance is the same; average effect is the same. Price is usually substantially lower.
Why does Prozac cost more than generic Fluoxetine? ▾
The price difference reflects originator development costs, brand recognition and competition among generic manufacturers. The molecule is identical; the cost is not.
