What are Viagra Tablets
Viagra tablets are a medication used to treat erectile dysfunction in men. They contain the active ingredient sildenafil citrate, which helps increase blood flow to the penis, facilitating and maintaining an erection. Viagra tablets are usually taken orally and have proven to be effective in restoring sexual function for many individuals.

How does it work?
Viagra tablets work by inhibiting an enzyme called phosphodiesterase type 5 (PDE5). This enzyme is responsible for breaking down a chemical called cyclic guanosine monophosphate (cGMP), which plays a crucial role in relaxing the smooth muscles of the penis and increasing blood flow to it. By inhibiting PDE5, Viagra allows cGMP to accumulate, promoting and sustaining an erection when sexual stimulation occurs. It should be noted that Viagra only works in the presence of sexual arousal and does not increase sexual desire.
Viagra tablets are available in various dosages, including 25 mg, 50 mg, and 100 mg. The recommended starting dose is typically 50 mg, which can be adjusted based on individual response and tolerability. It is generally recommended to take Viagra approximately 30 minutes to 1 hour before sexual activity, with a maximum frequency of once per day. However, it is important to consult with a healthcare professional for personalized dosage instructions, as they can provide guidance based on individual needs and medical history.
Viagra tablets may cause some side effects, although not everyone experiences them. Common side effects include headache, facial flushing, indigestion, nasal congestion, dizziness, and visual disturbances (such as blurred vision or changes in color perception). These side effects are usually mild and temporary.
In rare cases, more serious side effects can occur, such as priapism (a prolonged and painful erection lasting more than 4 hours), sudden vision loss, or hearing loss. If any of these severe side effects occur, immediate medical attention should be sought.
It's important to note that Viagra should not be taken with certain medications, particularly those containing nitrates (commonly prescribed for chest pain), as this combination can cause a dangerous drop in blood pressure. Therefore, it is crucial to inform your healthcare provider about any medications you are taking to ensure their compatibility with Viagra.
It is always recommended to consult with a healthcare professional for a comprehensive understanding of potential side effects and individual risk factors before starting any medication.
Before taking Viagra tablets, it is important to consider certain precautions:
Consult a healthcare professional: Speak with a doctor or pharmacist to determine if Viagra is suitable for you, especially if you have any underlying medical conditions or take other medications.
Inform about medical history: Provide your healthcare provider with a comprehensive medical history, including any heart conditions, liver or kidney problems, blood disorders, or previous instances of priapism.
Avoid certain medications: Do not take Viagra if you are currently using nitrates (such as nitroglycerin) for chest pain or if you are taking medications known as alpha-blockers, as they can interact with Viagra and cause a significant drop in blood pressure.
Allergic reactions: Inform your healthcare provider about any known allergies, especially to sildenafil or any other ingredients in Viagra tablets.
Alcohol and grapefruit juice: Limit or avoid alcohol consumption while taking Viagra, as it may increase the likelihood of certain side effects. Grapefruit juice may also interact with the medication, so it is best to avoid consuming it.
Priapism: Seek immediate medical attention if you experience a prolonged and painful erection lasting more than 4 hours (priapism), as it can damage the penis if left untreated.
Remember, these are general precautions, and it is essential to consult with a healthcare professional for personalized advice based on your specific health circumstances.
