With both of these drugs, however, patients must realize that they do not have 100% success and that the success rate has a lot to do with the severity of ed. Also, patients must understand that it is normal to have to increase one’s dose as the problem of ED progresses and that nearly all patients who had initial success with ED pills will eventually lose that degree of success and may need other help. Both drugs take approximately 30 to 60 minutes to begin working and allow patients to achieve the erection they expect.

In addition to the daily or "on-demand" use, Cialis and 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 viagra connect form enlarged prostate, also known as benign prostatic hyperplasia (BPH). With Viagra, the drug is only licensed for the treatment of ED. Cialis and Viagra are also sometimes used off-label to treat Raynaud's syndrome, a condition in which your fingers turn numb and blue when exposed to cold. When patients come to us looking for relief from their erectile dysfunction, they are faced with a preliminary decision of which medication, tadalafil or sildenafil, is better.
The Bottom Line
Back in the day, when these medications were still on patent AND named Cialis and Viagra, respectively, they were very costly. These were the days of fighting with and often losing to insurance companies. Now that generics are available, so many more people can take advantage of these great, highly effective drugs. We often suggest that patients taking ED medications for the first time try both separately to see which works best for them with the fewest side effects. Ultimately, with prices as low as they are, there’s little financial risk in seeing which is best for our patient’s unique circumstances. Peak concentration in the blood is reached after two hours for tadalafil and about one hour for sildenafil.

As such, we always suggest taking medication about an hour or two before sexual activity.
How Long Do ED Medications Work?
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. Cialis (tadalafil) and Viagra (sildenafil) are both phosphodiesterase type 5 (PDE5) inhibitors used to treat erectile dysfunction (ED).
How much Viagra should I take the first time?
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. 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.
Casual sex and Viagra
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. The time it takes for the drug to function will vary between patients, so use prior experience as a guide. Of note, sildenafil, a generic Viagra, can be somewhat inhibited after eating a large meal containing fatty foods, and this is not a concern with tadalafil (generic Cialis). We often suggest sildenafil for married couples or long-term partners with a more predictable sex life.

Cialis may be more appropriate for patients who are dating, as the big meals often associated with early dating can cause sildenafil to be less effective. Regarding which medication allows an erection to last longer, the clear winner is tadalafil. Sildenafil remains effective for four to six hours, while tadalafil will enable patients to achieve erections up to 36 hours after ingestion, an effect usually seen in younger patients or lesser degrees of ED. In both cases, the drug does not increase desire, instead allowing for a better erection when the desire is present.

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 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. 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. Doing so also increases the risks of stomach upset and nausea.
Patient resources
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. 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). As with any medication, side effects are associated with both sildenafil and tadalafil.
| Side Effect | Common Symptoms | When to Seek Medical Help |
|---|---|---|
| Headache | Mild to severe | Severe or persistent headaches |
| Visual disturbances | Blurred vision, color changes | Immediately consult a doctor |
| Chest pain | Discomfort, pressure | Emergency situation |
| Prolonged erection (Priapism) | Lasts over 4 hours | Urgent medical attention needed |
| Dizziness | Lightheadedness | Stop activity and rest |
Generally, however, both drugs are well tolerated and have few severe side effects.
What Factors Impact the Effectiveness of Viagra?
That’s why it has the nickname, the “weekend pill”. Tadalafil provides a wider window of opportunity. So, if you and your partner are looking for a bit more spontaneity, this option might be a better fit. Tadalafil is another PDE-5 inhibitor, meaning that it is affected by similar external factors as Sildenafil. However, Tadalafil is not so much affected by food.
How to take Viagra safely
How long Viagra takes to kick in will always depend to some extent on your own body and how it reacts to the drug. However, most men can expect to achieve an erection that is firm enough for sex about 30-60 minutes after taking the tablet. Viagra’s active ingredient, Sildenafil, typically stays active in your body for up to 4 hours — so sex will take some planning! If you prefer greater spontaneity in your sex life, Tadalafil is an effective, longer-lasting alternative to consider. ED shouldn’t stop you from enjoying yourself.

Regarding how sildenafil and tadalafil work, they are very similar in that they are both PDE-5 inhibitors. This means they slow or stop the action of the phosphodiesterase type five enzyme in the body. This mechanism increases blood flow to the penis when a man is aroused. It’s worth noting, however, that these medications do not increase sexual desire. Instead, they allow the penis to better fill with blood and achieve a satisfactory erection. Patients may also develop a blue hue to their vision. Most of these side effects are transient and will disappear after stopping the drug.

| Advertising regulations | Must not imply permanent or guaranteed results | Ethical marketing practices |
Loss of vision is a potentially severe side effect of sildenafil in certain very rare clinical situations, and you should stop the drug and get medical help immediately if this occurs, as this can, in very rare cases, lead to permanent blindness. Patients with certain eye problems, cardiovascular and metabolic diseases (high cholesterol, high blood pressure, and type 2 diabetes), and smokers may be at higher risk. Patients taking tadalafil have a slightly different side effect profile.

Like sildenafil, tadalafil can cause headaches, indigestion, and nasal congestion. However, tadalafil can also cause unique symptoms like back pain, cough, and upper respiratory tract infections. Interestingly, while both drugs have side effects, recent studies have shown that they may reduce the risk of early death from heart disease by up to 25%. This does not make them a treatment for heart disease, nor does it replace any therapies you may currently be taking for cardiovascular issues. Both drugs have a relatively mild risk profile. It is worth noting that any side effects experienced from tadalafil will typically last longer because the drug remains in the bloodstream significantly longer than sildenafil.
