Flibanserin
Flibanserin, sold as Addyi in the US, is a once-a-day bedtime tablet for women with persistent low sexual desire. It works on desire itself, not on blood flow.
Flibanserin is one of the few medicines made for low sexual desire in women. Sprout Pharmaceuticals sells it in the US as Addyi, where it is approved for women under 65 with acquired, generalised hypoactive sexual desire disorder (HSDD): low desire that causes real distress and is not explained by another condition, relationship problems or a medicine. Women choose it because it works on desire itself, which blood-flow medicines such as sildenafil do not.
Flibanserin at a glance
- Made by: Sprout Pharmaceuticals, as Addyi in the US. Our partner store lists a generic flibanserin 100 mg tablet.
- What is inside: flibanserin 100 mg, a medicine that acts on serotonin in the brain, not a PDE5 inhibitor like sildenafil.
- The format: a tablet. Addyi itself is a pink, oval 100 mg tablet.
- Preparation: A daily bedtime medicine under the Addyi label, rather than an on-demand tablet.
- Compare with: Lovegra.
The Flibanserin format
Flibanserin is a daily routine rather than a pill for the moment: one tablet at bedtime, every night. The label sets bedtime because taking it while awake raises the risk of low blood pressure, fainting and sleepiness. It also advises waiting at least six hours after a dose, and until you know how it affects you, before driving. If you miss a dose, take the next one at bedtime the following day; do not double up.
It is a medicine you give time. In the approval trials, the average improvement was modest, and the label says to stop after 8 weeks if there is no improvement. The most common side effects were dizziness, sleepiness, nausea and tiredness.
Flibanserin or Lovegra?
| Flibanserin (Addyi) | Lovegra (sildenafil) | |
|---|---|---|
| Active ingredient | Flibanserin 100 mg | Sildenafil 100 mg |
| Works on | Low sexual desire | Blood flow during arousal |
| How it is taken | Every day, at bedtime | Before sex, as needed |
| US regulatory status | FDA-approved for HSDD in women under 65 | Not FDA-approved for women |
| Best for | Persistent low desire that causes distress | Questions about the physical side of arousal |
The two are often both called “female Viagra”, but they answer different questions: flibanserin is about desire, Lovegra about the body’s response.

Flibanserin questions
How do you take flibanserin?
A daily bedtime medicine under the Addyi label, rather than an on-demand tablet. See the strength section above for the medicine context.
Is flibanserin female Viagra?
No. Viagra and Lovegra contain sildenafil, which works on blood flow before sex. Flibanserin is a daily medicine that works on desire.
Can I drink alcohol while taking it?
Not freely. The label asks you to wait at least two hours after one or two drinks before the bedtime dose, to skip the dose after three or more, and to avoid alcohol after taking it until the next day.
How long before I know if it helps?
Give it time. The FDA label says to stop after 8 weeks if there is no improvement.
Is it available in Singapore?
Check the exact product in HSA’s public register. A US approval or an overseas listing does not mean it is registered in Singapore.
Start with the symptom, not the product name
Desire and physical arousal are different things. Compare what each medicine is made for and pick the one that fits your question.
