Our Vidalista 100mg tablet contains the best of all possible quality ingredients at a fraction of the cost of Viagra. Our Vidalista 100mg is an all-in-one tablet that provides the best of all possible benefits for your overall health. It contains Vardenafil as its active ingredient, which works by relaxing the muscles in the walls of blood vessels, allowing for better blood flow to the penis, especially during sexual arousal. When combined with sexual stimulation, Vidalista 100mg enhances the function of the penis by allowing for an erection.
Both Phuket’s Vidalista 100mg and Viagra Connect have the same active ingredient, Vardenafil. This means that they work similarly, allowing you to achieve and sustain an erection when sexually stimulated. Vardenafil provides an extended duration of action, allowing for more spontaneous sexual activity compared to Viagra Connect.
On the other hand, Vidalista contains more sildenafil, which enhances blood flow to the penis, promoting a stronger and longer-lasting erection. This makes it a popular choice among users of Viagra and its similar alternatives like Cialis.

As with any new medication, there are potential side effects. It’s important to note that these are not all the same. It’s also important to consult with a healthcare professional before starting any medication. They can assess your medical history, current health status, and any underlying health conditions. They can also determine if Viagra is the right medication for you.
Understanding Viagra: What It Is and How It Works
Viagra, or sildenafil, is a medication that is primarily used to treat erectile dysfunction (ED) in men. It works by increasing the blood flow to the penis, allowing men to achieve and maintain an erection when sexually stimulated. Viagra also helps reduce stress and anxiety related to sexual encounters. It’s important to note that Viagra isn’t a magic pill. It works differently than other ED medications.
When taken orally, Viagra can work by increasing blood flow to the penis to help men achieve and maintain an erection. It’s important to follow the dosage instructions provided by your healthcare professional and only take Viagra if it’s deemed medically necessary. When you take Viagra, you will experience increased blood flow to the penis. This can lead to increased erections and improved sexual performance.
It’s also important to understand that Viagra does not work for everyone. Men with certain medical conditions or taking other medications can have side effects that may occur. Additionally, Viagra can interact with other medications, so it’s important to inform your healthcare provider about any existing medical conditions or medications you are taking to avoid potential interactions.
How Viagra Works in the Body
Viagra belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. This class of medications works by blocking the PDE5 enzyme, which is responsible for breaking down the drug in the body. By inhibiting this enzyme, Viagra can help relax the blood vessels in the penis, allowing for increased blood flow and resulting in an erection. Viagra is often prescribed for individuals with conditions like pulmonary arterial hypertension (PAH) or high blood pressure.
PDE5 inhibitors like Viagra work by blocking PDE5 to prevent degradation of the drug in the body. This allows the medication to work effectively and is a common side effect.
Viagra is available in tablet form and is available in several strengths, including 25mg, 50mg, and 100mg. The recommended starting dose is 50mg, but it can be increased to 100mg based on individual response and tolerability. Viagra is typically taken about 30 minutes to an hour before sexual activity.
If you have underlying health conditions, such as heart disease or liver or kidney problems, Viagra may not be suitable for you. It’s important to discuss any pre-existing medical conditions and medications you’re taking with your healthcare provider to determine if Viagra is the right medication for you. They will also evaluate your overall health to determine if Viagra is an appropriate option for you.
Common Side Effects and Risks
Like any medication, Viagra can have potential side effects. Common side effects include headache, flushing, upset stomach, nasal congestion, and indigestion.
