Male vs Female Viagra: Side Effects & Benefits

Viagra is a well-known name in the world of sexual health, primarily associated with treating erectile dysfunction (ED) in men. However, in recent years, interest has grown around a so-called “female Viagra” — drugs designed to address sexual dysfunction in women. Though both aim to improve sexual function, male and female versions of Viagra differ significantly in their mechanisms, applications, side effects, and benefits. This blog explores the differences between male and female Viagra, shedding light on their respective roles, effects, and considerations.

What Is Male Viagra?

Male Viagra is the brand name for sildenafil citrate, a prescription medication used to treat erectile dysfunction (ED) in men. Approved by the FDA in 1998, Viagra works by increasing blood flow to the penis, making it easier to achieve and maintain an erection when sexually stimulated.

How It Works:

Sildenafil belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. It relaxes the muscles in the blood vessel walls, particularly in the penis, enhancing blood flow during sexual arousal.

Benefits of Male Viagra:

• Effective ED treatment: Most users report improved ability to get and sustain erections.
• Quick onset: Effects typically begin within 30 to 60 minutes.
• Long track record: Years of clinical use and studies have established its safety and efficacy.

Common Side Effects of Male Viagra:

• Headache
• Flushing
• Nasal congestion
• Indigestion
• Dizziness
• Vision changes (e.g., a blue tint)

Serious but Rare Side Effects:

• Priapism (prolonged erection)
• Sudden hearing or vision loss
• Heart-related complications in predisposed individuals

What Is Female Viagra?

The term “female Viagra” is somewhat misleading. It doesn’t refer to a direct equivalent of sildenafil for women. Instead, it typically refers to flibanserin (Addyi) or bremelanotide (Vyleesi)—two FDA-approved drugs aimed at treating hypoactive sexual desire disorder (HSDD) in premenopausal women.

1. Flibanserin (Addyi):

• A daily oral medication
• Works on serotonin and dopamine receptors in the brain
• Designed to increase sexual desire over time

2. Bremelanotide (Vyleesi):

• An injectable drug taken as needed before sexual activity
• Works on the melanocortin receptors involved in sexual motivation

How Female Viagra Works:

Unlike male Viagra, female sexual dysfunction is often not due to blood flow issues. Instead, it tends to involve brain chemistry, hormones, and emotional factors. Female Viagra targets these aspects by modulating neurotransmitters that influence sexual desire.

Benefits of Female Viagra:

• Improves sexual desire in women with HSDD
• Psychological boost in confidence and intimacy
• Option for women with no obvious physical cause for low libido

Common Side Effects of Female Viagra:

For Flibanserin (Addyi):

• Dizziness
• Nausea
• Fatigue
• Low blood pressure
• Sleepiness

For Bremelanotide (Vyleesi):

• Nausea (very common)
• Flushing
• Injection site reactions
• Headache
• Temporary increase in blood pressure

Important Considerations:

• Alcohol interaction: Addyi should not be used with alcohol due to risk of severe hypotension and fainting.
• Timing: Addyi must be taken daily, while Vyleesi is used as needed.
• Effectiveness varies: Some women report modest improvements, while others may see little change.

Male vs Female Viagra: Key Differences

Aspect	Male Viagra (Sildenafil)	Female Viagra (Flibanserin/Vyleesi)
Target Condition	Erectile Dysfunction (ED)	Hypoactive Sexual Desire Disorder (HSDD)
Mechanism	Increases blood flow to the penis	Alters brain chemicals that affect desire
Onset Time	30–60 minutes (as needed)	Daily (Addyi) or as needed (Vyleesi)
Target Gender	Men	Women
Effect	Facilitates erections	Increases sexual desire
Side Effects	Vision changes, flushing, headache	Nausea, dizziness, fatigue, injection site pain
Alcohol Warning	Mild interaction	Strong contraindication (especially with Addyi)

Do They Work the Same Way?

Absolutely not. Male Viagra addresses the physical side of sexual function by improving blood flow, while female Viagra addresses the mental and emotional components of sexual desire. This fundamental difference means that what works for men may not necessarily work for women, and vice versa.

Are There Female Versions of Sildenafil?

There have been off-label uses of sildenafil in women, especially to increase blood flow to the genital area. However, clinical trials have not shown consistent results in improving sexual satisfaction or desire in women. For this reason, sildenafil is not FDA-approved for female sexual dysfunction.

That said, some researchers continue to explore sildenafil’s potential for certain conditions like female sexual arousal disorder (FSAD) or sexual dysfunction post-menopause, but more conclusive evidence is needed.

Risks and Warnings

Both male and female Viagra medications have potential risks and should not be used without medical consultation.

Men should avoid sildenafil if:

• They take nitrates for heart disease
• Have severe cardiovascular issues
• Are allergic to sildenafil or similar drugs

Women should avoid flibanserin or bremelanotide if:

• They are pregnant or breastfeeding
• Have liver impairment
• Use alcohol (particularly with Addyi)

Who Should Use These Medications?

Ideal Candidates for Male Viagra:

• Men with ED due to physical, psychological, or mixed causes
• Those who do not have contraindicated heart conditions or take nitrates

Ideal Candidates for Female Viagra:

• Women diagnosed with HSDD
• Pre-menopausal women experiencing persistent low libido not caused by another medical condition, medication, or relationship issue

It’s important to understand that these drugs are not aphrodisiacs. They do not create desire or arousal on their own but work in specific biological contexts. Emotional, psychological, and relationship factors also play major roles in sexual health.

Final Thoughts

While male and female Viagra may share a nickname, they are very different in how they work, what they treat, and their side effect profiles. Male Viagra (sildenafil) is well-established for erectile dysfunction, offering fast-acting results with a clear physical target. Female Viagra (flibanserin and bremelanotide), on the other hand, targets low sexual desire in women through brain chemistry rather than blood flow.
