This includes special formulations of tadalafil and sildenafil, called Adcirca and Revatio, that are approved to treat pulmonary arterial hypertension (high blood pressure in the lungs). In addition to the daily or "on-demand" use, Cialis and yellow viagra pill Viagra have also been given different approvals by the U.S. Food and Drug Administration (FDA): With Cialis, in addition to ED, the drug can also be taken as a 5-mg daily dose to treat an enlarged prostate, also known as benign prostatic hyperplasia (BPH).

Comparing Which Lasts Longer

At the time of approval, the FDA argued that Addyi’s interaction with alcohol hadn’t yet been adequately studied. In 2019 and after additional research was conducted, the FDA modified its original alcohol viagra click and collect warning for Addyi and removed the test requirement for doctors and pharmacists. In December of 2025, the FDA approved the drug for postmenopausal women, expanding access to more patients. Advocates say a drug to treat women’s sexual dysfunction is a start to addressing health inequity. Lee adds that recent bigger picture events, though, like the overturn of Roe v.

Are Cialis and Viagra safe to use while pregnant and breastfeeding?

Wade and rollbacks on birth control access, have changed what health care looks like for women today. The approval and acceptance of Addyi is part of a much larger and ongoing conversation about women’s health and regulatory policy currently. “The past five to 10 years really calls into question where the state of women’s health is going,” Lee said. The Pink Pill: Sex, Drugs & Who Has Control is streaming on Paramount+ in Canada and the U.S. as of March 6, 2026. With Viagra, the drug is only licensed for the treatment of ED.

• Cialis and Viagra are often compared for their onset of action and duration, relevant to women's sexual needs.
• While Viagra increases blood flow, its impact on female libido remains largely anecdotal without conclusive evidence.
• Cialis in women is under investigation; some small studies suggest it may help with blood flow issues affecting arousal.
• Both medications are contraindicated for women with cardiovascular issues or those taking certain medications.
• Women should be aware that these drugs are not approved specifically for female sexual dysfunction in many countries.
• Psychological health plays a critical role in female sexual desire, beyond what medications can address.
• There are alternative treatments for women, including hormonal therapy, that may be more effective than Cialis or Viagra.
• Patients should report any adverse effects or unusual symptoms to their healthcare professional promptly.

• Cialis contains tadalafil, which has a longer duration of action than Viagra but limited proof of benefit for women.
• Evidence suggests that some women may experience improved sexual function with these medications, but results vary widely.

However, each has different side effects, dosage schedules, and other factors.

• Testosterone therapy, not PDE5 inhibitors, is more commonly studied for low libido in surgically menopausal women.
• This highlights desire versus arousal as different targets for medication.
• Hormone replacement therapy is a complex consideration on its own.

Here, we look at how they stack up. Viagra and Cialis are oral medications used to treat erectile dysfunction (ED). You may also know them by their generic names: sildenafil (Viagra) and tadalafil (Cialis).

About 30 million men in the United States occasionally have a problem with getting or keeping an erection, according to the Urology Care Foundation.

Side effects

Cialis lasts up to 36 hours, making it a long-acting option. Viagra works faster, with effects in 30 minutes, but lasts only about four hours. Cialis is also approved for treating an enlarged prostate and has fewer food restrictions. Cialis and Viagra both work to treat erectile dysfunction, but they differ significantly in how long they last and when they start working. While Cialis can last up to 36 hours, Viagra offers a quicker onset within 30 minutes.

Onset Time

Cialis (tadalafil) and Viagra (sildenafil) are both phosphodiesterase type 5 (PDE5) inhibitors used to treat erectile dysfunction (ED). They increase blood flow to the penis, which helps produce an erection suitable for sex. A key difference between Cialis and Viagra is their duration of action, largely determined by their biological half-life. This refers to the time it takes for drug levels in the bloodstream to drop by half. Cialis has a longer half-life than Viagra, leading to a longer duration of action: Cialis: Works up to 36 hours (giving it the nickname "the weekend pill") Viagra: Works up to around four hours, with the strongest effects seen in the first two hours PDE5 inhibitors prevent the breakdown of cyclic guanosine monophosphate (cGMP), which relaxes blood vessels and increases blood flow to the penis for stronger erections. When ED becomes a problem, many turn to these oral ED medications to help address the issue.

How They Work

A more recent study found that about half of women taking Addyi reported benefit to their sex life. Advocates for women’s health criticized the FDA’s early rejections and claimed gender bias, especially because Viagra was approved under an expedited priority review process, taking less than a year to achieve approval. Though the purposes of Addyi and Viagra are similar, Addyi corrects chemical imbalances of certain neurotransmitters in the brain that are responsible for sexual desire or excitement, which makes the drug approval process more complex. “Erectile dysfunction was seen as an unmet physical ailment,” said Lee. Because of that, Viagra was evaluated as treatment to address a physical need.

Increased genital blood flow

HSDD was not considered an unmet physical ailment in the eyes of the FDA but rather an unmet psychological ailment, which “immediately triggers a higher standard of review and additional safety measures,” Lee adds. While the drugs had to be evaluated differently, supporters of Addyi claimed that stigma and overly cautious FDA warnings deterred patient use even after it was approved. For example, doctors and pharmacists had to take a test, known as a Risk Evaluation and Mitigation Strategy assessment, to prescribe and administer Addyi. The assessment included an online slide presentation followed by a comprehension test that proved the medical professionals knew and understood the drug’s risks of potential low blood pressure and fainting when combined with alcohol. Even further, patients had to sign a paper vowing not to drink while on the medication even though Cialis--another medication used to treat erectile dysfunction in men--creates similar interactions with alcohol but comes with no more than an advisement to moderate alcohol use. However, they also have some key differences, such as when you take them, how long they work, and what their side effects are.

Comparing Drug Interactions

With Viagra, the drug is only used in anticipation of sex. Due to its short half-life, it is unsuitable for daily use. Cialis and Viagra vary in their effectiveness when taken with food: With Cialis, you can take a dose, even a small 2.5-mg dose, with or without food. The rate and degree of absorption of the drug are unaffected by food. With Viagra, taking a dose with food, especially high-fat foods, reduces its absorption and can make it less effective. We break it down further for you below.

Cost and Availability of Generics

In other words, women and minority groups often don’t have a similar, positive experience. “FDA decisions are not just scientific determinations, but structural choices that shape access, risk, and who benefits from innovation,” said Lee. The FDA declined approval for Addyi in 2010 and 2013, with some critics referring to the treatment as “an ineffective drug for a nonexistent problem.” However, data from the University of Colorado Anschutz Department of Obstetrics and Gynecology shows that 10% of women across all age groups suffer from HSDD, which can “cause significant levels of personal distress.” To put it into perspective, HSDD is just as common as autoimmune disorders like rheumatoid arthritis, and in the U.S. alone there are nearly a million patients taking oral medication to treat their autoimmune condition. Though HSDD is not a threat to physical wellbeing, both conditions can have significant impact on a person’s life.

Key takeaways

Like most medications, Addyi doesn’t work for everyone, but its availability gives women struggling with HSDD an option that otherwise doesn’t exist. Still, early research didn’t quite satisfy the FDA. “When the data first went up for review in 2010, the FDA did not feel that there was enough data to support Addyi’s effectiveness,” said Lee. The drug was originally tested in a clinical trial with over 2,000 premenopausal women either taking Addyi or a placebo pill. Participants taking Addyi were 10% more likely to report an increase in satisfying sexual events. The main differences between Viagra and Cialis, aside from their chemical makeup, are how long it lasts in your system and the dosage.

Does one make you harder than the other?

The onset of action, or how quickly Cialis and Viagra work, depends on their peak plasma concentration—the point when the drug reaches its highest level in the blood after liver metabolism. With Cialis, the peak plasma concentration is reached in around two hours, translating to an onset of action of roughly one hour. With Viagra, the peak plasma concentration is reached in around one hour, translating to an onset of action of 30 minutes or less. Cialis and Viagra share mechanisms of action but differ in side effects. According to pre-market trials, potential side effects include the following.

*Based on the recommended "on-demand" dose Cialis comes in oral tablets of 2.5 mg, 5 mg, 10 mg, and 20 mg. For immediate ED treatment, you typically start with 10 mg and adjust based on tolerability or effectiveness. Viagra is also available in oral tablets of 25 mg, 50 mg, and 100 mg. It's typically used at 50 viagra over the counter mg once daily, but can be increased to 100 mg if needed. In terms of dosage, there is one big difference between Cialis and Viagra: With Cialis, you can take it "on demand" for the immediate treatment of ED or as a daily dose to achieve sustained relief of ED in a lower 2.5- or 5-mg dose. Keep in mind, though, that the effects for each pill vary by person and other medications you take. While Viagra and sildenafil have a life span of 4 to 6 hours, Cialis (and generic tadalafil) can stay in your system for up to 36 hours.

Side Effect	Severity	Notes
Headache	Mild	Common in many users
Flushing	Mild	Usually temporary
Vision Changes	Rare	Possible blue tint or blurred vision

It also takes Cialis and tadalafil anywhere from 30 minutes to 6 hours to take effect. Whereas you can feel the effects of Viagra anywhere between 30 and 60 minutes. Each medication has its own dosage meter. Viagra doses are 25 milligrams (mg), 50 mg, and 100 mg.

Alternatives to Low Libido Medications

Doing so also increases the risks of stomach upset and nausea. That said, all PDE5 inhibitors are about 70% effective at helping people have better erections. None is considered superior to the other in this respect. That means seven out of 10 people who take a drug like Cialis or Viagra will have more frequent or longer-lasting erections. PDE5 inhibitors are sometimes used to treat other conditions besides ED. Cialis and tadalafil doses are 5 mg, 10 mg, and 20 mg. Cialis also has a lower dose of 2.5 mg that you can take daily. The reasoning behind this is that over time, Cialis stays in your system and can help you get an erection as opposed to taking a pill a certain time before sexual activity.
