Brief overview of Cialis and Viagra
Cialis and Viagra are two medications commonly used to treat erectile dysfunction (ED) in men. Cialis, also known as tadalafil, was first approved by the Food and Drug Administration (FDA) in 2003 and Viagra, also known as sildenafil citrate, was first approved by the FDA in 1998. Both medications work by increasing blood flow to the penis, which helps a man achieve and maintain an erection. However, there are some key differences between the two drugs, including their active ingredient, dosage, duration of effect, and side effects.
Difference Between Cialis and Viagra
Active Ingredient
The active ingredient in Cialis is tadalafil, while the active ingredient in Viagra is sildenafil citrate. Both medications belong to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors, which work by relaxing the blood vessels in the penis, allowing more blood to flow into the area and helping a man achieve and maintain an erection. However, the chemical structures of tadalafil and sildenafil citrate are different and thus may have slight differences in how they work.
Tadalafil has a longer half-life compared to sildenafil citrate, meaning it stays in the body for a longer period of time. This can result in Cialis having a longer duration of effect, up to 36 hours. On the other hand, the effects of sildenafil citrate typically last for 4-6 hours.
It’s important to note that these medications should only be taken under the prescription and guidance of a licensed healthcare provider, as they may interact with other medications or have contraindications with certain medical conditions.
Dosage
The recommended dosage for Cialis and Viagra can vary depending on the individual and the condition being treated.
For Cialis, the recommended starting dosage for treating ED is 10 mg, taken before sexual activity. The dosage can be increased to 20 mg or decreased to 5 mg, depending on the individual’s response and tolerance. The maximum recommended dosage is 20 mg.
For Viagra, the recommended starting dosage for treating ED is 50 mg, taken about one hour before sexual activity. The dosage can be increased to 100 mg or decreased to 25 mg, depending on the individual’s response and tolerance. The maximum recommended dosage is 100 mg.
It’s important to note that these medications should only be taken under the prescription and guidance of a licensed healthcare provider, as they may interact with other medications or have contraindications with certain medical conditions.
Duration of Effect
The duration of effect for Cialis and Viagra can vary, with Cialis generally having a longer duration of effect than Viagra.
The active ingredient in Cialis, tadalafil, has a longer half-life compared to the active ingredient in Viagra, sildenafil citrate. This means that tadalafil stays in the body for a longer period of time, resulting in Cialis having a longer duration of effect. The effects of Cialis can last for up to 36 hours.
On the other hand, the effects of Viagra typically last for 4-6 hours. However, it’s worth noting that the duration of effect can vary depending on the individual and may be affected by factors such as diet, alcohol consumption, and overall health.
It’s important to note that these medications should only be taken under the prescription and guidance of a licensed healthcare provider, as they may interact with other medications or have contraindications with certain medical conditions.

Common side effects associated with Viagra include:
- Headache

- Visual changes (such as changes in color perception, increased sensitivity to light)
- Dizziness
- Blue-tinted vision
- Blurred vision
- Light sensitivity
It’s important to note that these are only the most common side effects and that the list is not exhaustive. If you experience any severe side effects, you should seek medical attention immediately.
It’s important to keep in mind that these medications should only be taken under the prescription and guidance of a licensed healthcare provider, as they may interact with other medications or have contraindications with certain medical conditions.
Uses
Cialis and Viagra are both FDA-approved medications for the treatment of erectile dysfunction (ED) in men. Both medications work by increasing blood flow to the penis, which helps a man achieve and maintain an erection.
Cialis is also FDA-approved for the treatment of benign prostatic hyperplasia (BPH), also known as an enlarged prostate. Tadalafil, the active ingredient in Cialis, can help relax the muscles in the prostate and bladder, which can improve symptoms of BPH such as difficulty starting urination, weak stream, and the need to urinate frequently.
In addition, Cialis is also FDA-approved for the treatment of pulmonary arterial hypertension (PAH), a rare lung disorder that can cause high blood pressure in the lungs and make it difficult to breathe. Tadalafil can help relax the blood vessels in the lungs and improve blood flow.
Viagra is not FDA-approved for any other condition other than erectile dysfunction.
It’s important to note that these medications should only be taken under the prescription and guidance of a licensed healthcare provider, as they may interact with other medications or have contraindications with certain medical conditions.
Conclusion
