Quick Takeaways
- Sarafem is a brand‑name fluoxetine made for PMDD; generic fluoxetine works the same but costs less.
- Other SSRIs (sertraline, paroxetine, escitalopram) are off‑label options with similar efficacy.
- Venlafaxine, a SNRI, can help when SSRIs cause too many side effects.
- Weekly cost in Australia ranges from under $10 for generics to $30+ for brand names.
- Choosing the right pill depends on how you react to side‑effects, insurance coverage, and personal preferences.
What is Sarafem?
When you see Sarafem is a brand‑name fluoxetine formulation approved by the FDA for premenstrual dysphoric disorder (PMDD), think of it as the same molecule you’d find in a cheap capsule, but marketed specifically for the menstrual‑cycle mood swings that affect about 5% of people who menstruate.
How Sarafem works for PMDD
Fluoxetine, the active ingredient, is a selective serotonin reuptake inhibitor (SSRI). It boosts serotonin levels in the brain, which smooths out the emotional roller‑coaster that peaks in the luteal phase of the cycle. Most users start with 20mg daily, taken continuously or only during the two weeks before menstruation, depending on the doctor’s advice.
Pros and cons of Sarafem
Pros
- Clinically proven for PMDD, so insurance often covers it under psychiatric benefits.
- Once‑daily dosing simplifies adherence.
- Extensive safety data from decades of fluoxetine use.
Cons
- Higher price than generic fluoxetine - a typical 30‑day pack costs AU$35‑45.
- Some people report more nausea or insomnia compared with other SSRIs.
- Limited to adult dosing; paediatric use is off‑label.
Top alternatives to Sarafem
Below are the most common alternatives, each with its own microdata definition.
Fluoxetine (generic) is a non‑brand version of the same active ingredient, usually sold in 10‑mg or 20‑mg tablets. It’s prescribed for depression, anxiety, and off‑label for PMDD. Cost per month hovers around AU$8‑12.
Sertraline is a different SSRI that many clinicians use off‑label for PMDD because it has a slightly lower sexual‑dysfunction profile. Typical dose: 50‑100mg daily. Weekly price about AU$15‑20.
Paroxetine is a SSRI known for a strong anxiolytic effect, sometimes chosen for severe mood swings. Dose ranges 10‑25mg daily; cost similar to sertraline.
Escitalopram is a highly selective SSRI praised for fewer side effects, especially nausea. Starts at 10mg daily; weekly cost about AU$18‑22.
Venlafaxine is a serotonin‑norepinephrine reuptake inhibitor (SNRI) that can be effective when SSRIs fall short. Typical dose 75‑150mg daily; price per week around AU$25‑30.
Premenstrual Dysphoric Disorder (PMDD) is a severe form of premenstrual syndrome characterized by mood swings, irritability, and physical symptoms that interfere with daily life. Diagnosis requires tracking symptoms across at least two menstrual cycles.
Side‑by‑side comparison
| Medication | FDA‑approved PMDD use? | Typical daily dose | Average weekly cost (AU$) | Common side effects |
|---|---|---|---|---|
| Sarafem (fluoxetine) | Yes | 20mg | 10‑12 | Nausea, insomnia, sexual dysfunction |
| Generic fluoxetine | Off‑label | 20mg | 2‑4 | Similar to Sarafem |
| Sertraline | Off‑label | 50‑100mg | 4‑6 | Diarrhea, dry mouth, dizziness |
| Paroxetine | Off‑label | 10‑25mg | 5‑7 | Weight gain, fatigue, sexual dysfunction |

| Venlafaxine | Off‑label | 75‑150mg | 8‑10 | Hypertension, sweating, constipation |
How to decide which medication fits you
Start with three questions:
- Do you need a medication that’s officially approved for PMDD? If insurance coverage is a priority, Sarafem or generic fluoxetine often win.
- How sensitive are you to sexual side effects? Escitalopram and sertraline tend to have a milder impact.
- Have you tried an SSRI before? If you experienced intolerable nausea, venlafaxine may be a useful backup.
Talk to your prescriber about these points, and ask for a trial period of 4‑6 weeks. Keep a symptom diary to see which drug eases mood swings without new problems.
Cost considerations in Australia
Most private health funds cover SSRIs under the “pharmaceutical benefits scheme” (PBS). However, brand‑name Sarafem is often listed at a higher co‑payment than generic fluoxetine. Retail prices (as of Oct2025) are:
- Sarafem 20mg - AU$35 for a 30‑day supply.
- Generic fluoxetine 20mg - AU$10 for the same quantity.
- Sertraline 100mg - AU$18.
- Paroxetine 20mg - AU$20.
- Escitalopram 10mg - AU$22.
- Venlafaxine 75mg - AU$24.
If cost is a blocker, ask the pharmacist for a PBS‑eligible brand‑generic substitution; the active ingredient will be identical.
Safety tips and common side‑effects
All the drugs listed affect serotonin pathways, so they share a few warnings:
- Don’t combine with monoamine‑oxidase inhibitors (MAOIs) - risk of serotonin syndrome.
- Watch for increased anxiety or agitation in the first two weeks; a short taper can help.
- Pregnancy? Fluoxetine and sertraline have the most safety data, but discuss with a OB‑GYN.
- Regular blood pressure checks if you’re on venlafaxine.
If any side‑effect becomes severe - like persistent suicidal thoughts or a rash - seek medical help right away.
Frequently Asked Questions
Is Sarafem the same as regular fluoxetine?
Yes, the only difference is the branding and dosage form. The active molecule is identical, so the therapeutic effect is the same.
Can I switch from Sarafem to generic fluoxetine without a doctor’s note?
You should always involve your prescriber. A gradual taper reduces withdrawal risk, and the doctor can confirm the same dosage is appropriate.
Which alternative has the lowest risk of sexual dysfunction?
Escitalopram and sertraline are generally reported to have milder effects on libido compared with fluoxetine or paroxetine.
Do I need to take the medication only during the luteal phase?
Both continuous daily dosing and intermittent “luteal‑phase only” regimens are used. Your doctor will decide based on symptom pattern and convenience.
Is venlafaxine a good backup if SSRIs don’t work?
Many clinicians turn to venlafaxine when SSRIs fail or cause intolerable side effects. It works on both serotonin and norepinephrine, which can help mood differently.
