Discover the differences between Viagra and Cialis to determine which medication may be more suitable for your needs. Learn about their effectiveness, side effects, and how they work to help you make an educated decision.
Viagra vs Cialis: Which One is Better?
Viagra and Cialis are both popular medications used to treat erectile dysfunction (ED). They belong to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors, which work by increasing blood flow to the penis. While both medications are effective, there are some differences that may make one more suitable for certain individuals than the other.
Viagra, also known by its generic name sildenafil, was the first oral medication approved by the US Food and Drug Administration (FDA) for the treatment of ED. It is typically taken 30 minutes to an hour before sexual activity and can last up to four hours. Cialis, on the other hand, contains the active ingredient tadalafil and is available in two different dosages – one for daily use and another for as-needed use. The daily dose of Cialis can be taken regardless of sexual activity and lasts throughout the day, while the as-needed dose is taken 30 minutes before sexual activity and can last up to 36 hours.

- Less affected by food and alcohol: Unlike Viagra, Cialis can be taken with or without food, and moderate alcohol consumption does not significantly affect its effectiveness.
- Lower dose options: Cialis is available in lower doses that can be taken daily, allowing for a more spontaneous and natural approach to sexual activity.
Cons of Cialis:
- Slower onset: Cialis may take longer to start working compared to Viagra, typically requiring about 2 hours before experiencing its full effects.

Ultimately, the choice between Viagra and Cialis depends on individual preferences, lifestyle, and specific needs. It is important to consult with a healthcare provider to determine the most suitable option based on factors such as overall health, medication interactions, and personal preferences.
Key differences between Viagra and Cialis
Viagra and Cialis are both prescription medications used to treat erectile dysfunction (ED), but they have some key differences in terms of how they work, how long they last, and their potential side effects.
Here are some of the main differences between Viagra and Cialis:
- Mechanism of action: Viagra contains the active ingredient sildenafil, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. It works by inhibiting the enzyme that regulates blood flow to the penis, allowing for increased blood flow and a firmer erection. Cialis, on the other hand, contains the active ingredient tadalafil, which also belongs to the PDE5 inhibitor class. However, Cialis has a longer duration of action compared to Viagra.
- Duration of action: Viagra typically lasts for about 4-5 hours, whereas Cialis can last for up to 36 hours. This means that Cialis is often referred to as the “weekend pill” because it can provide erectile function for an extended period of time.
- Onset of action: Viagra usually starts working within 30-60 minutes after taking the medication, while Cialis may take 1-2 hours to start working. This difference in onset time should be considered when planning sexual activity.
- Dosage: Viagra is available in doses of 25mg, 50mg, and 100mg, while Cialis comes in doses of 2.5mg, 5mg, 10mg, and 20mg. The appropriate dosage for an individual depends on factors such as their overall health, other medications they may be taking, and their response to the medication.
- Food and alcohol interaction: Viagra can be taken with or without food, but it may take longer to work if taken with a high-fat meal. On the other hand, Cialis can be taken with or without food and does not have any known interactions with alcohol.
- Side effects: The side effects of Viagra and Cialis are generally similar and may include headache, flushing, stomach upset, and dizziness. However, Cialis has been reported to have a lower incidence of side effects compared to Viagra.
It is important to note that both Viagra and Cialis should only be taken under the guidance of a healthcare professional, as they may interact with other medications and have potential risks in certain individuals.
How Viagra works
Viagra, also known by its generic name sildenafil, is a medication used to treat erectile dysfunction (ED) in men. It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Viagra works by increasing blood flow to the penis, which helps to achieve and maintain an erection.
When a man is sexually aroused, the arteries in the penis relax and widen, allowing more blood to flow into the erectile tissue. At the same time, the veins that normally carry blood away from the penis constrict, trapping the blood inside the erectile tissue. This combination of increased blood flow and reduced blood outflow results in an erection.
Mechanism of action
Viagra works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which is responsible for breaking down a substance called cyclic guanosine monophosphate (cGMP). cGMP is a molecule that helps relax the smooth muscles and dilate the blood vessels in the penis, allowing blood to flow in and produce an erection.
By inhibiting PDE5, Viagra increases the levels of cGMP in the penis, enhancing the natural mechanism of erection. However, sexual stimulation is still needed to activate the release of nitric oxide, which is required for the production of cGMP. Without sexual arousal, Viagra will not cause an erection.
Duration of action
The effects of Viagra typically last for about 4 to 5 hours. During this time, a man may experience improved erectile function and be able to achieve and maintain an erection when sexually aroused. However, the duration of action can vary depending on individual factors such as metabolism, dosage, and overall health.
It’s important to note that Viagra is not a cure for ED. It is a temporary solution that helps to improve erectile function while the medication is active in the body. To treat ED in the long term, underlying causes such as cardiovascular disease or hormonal imbalances may need to be addressed.
How Cialis works
Cialis, also known by its generic name tadalafil, is a medication commonly used to treat erectile dysfunction (ED) in men. It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Cialis works by increasing blood flow to the penis, which helps achieve and maintain an erection.
When a man is sexually stimulated, the arteries in the penis relax and widen, allowing more blood to flow into the erectile tissues. At the same time, the veins that normally carry blood away from the penis become compressed, restricting the outflow of blood. This combination of increased inflow and decreased outflow results in an erection.
Cialis helps facilitate this process by inhibiting the enzyme PDE5, which is responsible for breaking down a chemical called cyclic guanosine monophosphate (cGMP). cGMP is important for the relaxation of smooth muscles and the dilation of blood vessels in the penis. By inhibiting PDE5, Cialis allows cGMP to accumulate and enhance its effects on blood flow.
The recommended starting dose of Cialis for most men is 10 mg, taken before sexual activity. However, the dose may be adjusted based on individual response and tolerability. Cialis can be taken with or without food, and its effects can last up to 36 hours, earning it the nickname “the weekend pill.”
It’s important to note that Cialis does not cause an erection on its own. Sexual stimulation is still required for the medication to work. Additionally, Cialis is not a cure for ED, but rather a treatment that can help improve sexual function while the drug is active in the body.

Viagra contains the active ingredient sildenafil, which works by increasing blood flow to the penis. Cialis, on the other hand, contains the active ingredient tadalafil, which also increases blood flow to the penis but has a longer duration of action. This means that Cialis can be taken as a daily medication, while Viagra is usually taken on an as-needed basis.
Which one works faster, Viagra or Cialis?
Viagra typically works faster than Cialis. It usually starts working within 30 minutes to an hour after taking the medication. Cialis, on the other hand, may take up to 2 hours to start working.
