Sildenafil 20mg

Sildenafil 20 mg is a medication primarily used to treat erectile dysfunction (ED) in men. It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. ED is a condition where a man has difficulty achieving or maintaining an erection sufficient for sexual activity. Sildenafil works by inhibiting the enzyme phosphodiesterase type 5, which plays a role in regulating blood flow to the penis. 

By blocking this enzyme, sildenafil helps increase blood flow to the penis, leading to an improved ability to achieve and sustain an erection when sexually aroused. Aside from treating ED, sildenafil is also used to manage certain pulmonary arterial hypertension conditions.

 It is commonly known by its brand name Viagra, which is one of the most well-known and widely prescribed medications for erectile dysfunction. It's important to note that sildenafil 20 mg should only be taken under the supervision of a healthcare professional, as it may have interactions with other medications and can cause side effects in some individuals.

Uses of Sildenafil 20mg?

20mg Sildenafil is a medication primarily used to treat erectile dysfunction (ED) in men. It belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. Here are some common uses of Sildenafil 20 mg:

Erectile Dysfunction (ED): The primary and most well-known use of Sildenafil 20mg is for the treatment of erectile dysfunction. It helps to relax the smooth muscles in the blood vessels of the penis, allowing increased blood flow. This results in improved erectile function, helping men achieve and maintain an erection.

Pulmonary Arterial Hypertension (PAH): Sildenafil 20 mg is also used to treat pulmonary arterial hypertension, a condition characterized by high blood pressure in the arteries that supply the lungs. In this case, Sildenafil helps to relax the blood vessels in the lungs, reducing the workload on the heart and improving symptoms associated with PAH.

Altitude Sickness: Some studies have explored the potential use of Sildenafil in preventing and treating altitude sickness. The medication may help improve blood flow and oxygen delivery, which can be beneficial at high altitudes where oxygen levels are lower.

How to take medicine?

When taking Sildenafil 20 mg, it's important to follow the prescribed dosage and guidelines provided by your healthcare provider. Here are general instructions on how to take 20mg of Sildenafil:

  • Prescription: Sildenafil is a prescription medication, and it should only be taken under the supervision of a healthcare professional. Your doctor will determine the appropriate dosage based on your specific health condition, medical history, and other factors.
  • Timing: Sildenafil 20mg is usually taken as needed, about 30 minutes to 1 hour before sexual activity. It's important to note that the medication works best on an empty stomach. However, it can be taken with or without food.
  • Dosage: The typical starting dose is 20mg of Sildenafil, but your doctor may adjust the dosage based on your response to the medication. Do not exceed the recommended dose without consulting your healthcare provider.
  • Administration: Swallow the tablet whole with a glass of water. Do not crush, chew, or break the tablet, as this may affect the way the medication is absorbed in the body.
  • Sexual Stimulation: Sildenafil requires sexual stimulation to be effective. It does not cause an automatic erection but enhances the body's natural response to sexual arousal.

How does Sildenafil 20mg work?

20mg Sildenafil works by inhibiting the action of the enzyme phosphodiesterase type 5 (PDE5). This inhibition increases the levels of cyclic guanosine monophosphate (cGMP), leading to relaxation of the smooth muscles in the blood vessels of the penis. This, in turn, enhances blood flow to the area, promoting an erection.

Side Effects of Sildenafil 20 mg?

Sildenafil 20 mg, like any medication, can have side effects. It's important to note that not everyone will experience these side effects, and some individuals may experience side effects that are not listed. Common side effects of 20mg sildenafil may include:

  • Headache: One of the most common side effects, reported by some users.
  • Flushing (warmth or redness in the face and neck): This is also relatively common.
  • Indigestion or upset stomach: Some people may experience digestive issues.
  • Nasal congestion: A stuffy or runny nose.
  • Dizziness or lightheadedness: This can occur, especially when standing up quickly.
  • Vision changes: Sildenafil 20mg may cause changes in color vision or blurred vision.
  • Back pain or muscle pain: Some individuals may experience discomfort in the back or muscles.

It's important to seek immediate medical attention if you experience more serious side effects, such as:

  • Priapism: An erection that lasts longer than four hours. This requires urgent medical attention to prevent long-term damage to the penis.
  • Sudden vision or hearing loss: Although rare, sudden loss of vision or hearing requires immediate medical attention.
  • Allergic reactions: Symptoms may include rash, itching, swelling, severe dizziness, or difficulty breathing.


Sildenafil 20 mg, commonly known as Viagra in its higher doses, is a medication used to treat erectile dysfunction. When storing Sildenafil 20mg or any medication, it's important to follow the manufacturer's instructions and consider factors that maintain its effectiveness. Here are some general guidelines for storing Sildenafil 20:

  • Temperature: Store Sildenafil at room temperature between 68°F to 77°F (20°C to 25°C). Avoid extreme temperatures, such as freezing or high heat, as they can affect the stability of the medication.
  • Moisture: Keep Sildenafil in a dry place. Avoid storing it in humid environments like bathrooms. Moisture can degrade the quality of the medication.
  • Light: Store Sildenafil in its original packaging to protect it from light. Exposure to light, especially sunlight, can break down the active ingredients in the medication.
  • Container: Keep Sildenafil in its original container, tightly closed, and out of reach of children. The original packaging is designed to protect the medication from external factors that could affect its stability.
  • Expiry Date: Check the expiry date on the packaging and do not use the medication if it has expired. Expired medication may not be as effective and could potentially be harmful.
  • Away from Other Medications: Store Sildenafil away from other medications, and follow any specific storage instructions provided by the pharmacist or healthcare provider.

How Long Does 20 mg of Sildenafil Last?

The duration of action for sildenafil 20 mg, including the 20 mg dosage, can vary among individuals. In general, the effects of sildenafil typically last for about 4 to 6 hours. However, the actual duration can be influenced by several factors:

  • Individual Response: People may respond differently to the medication. Some individuals may experience the effects for a shorter or longer duration than others.
  • Dosage: Higher dosages may extend the duration of action, but they also increase the risk of potential side effects.
  • Food Intake: Taking sildenafil 20mg with a high-fat meal may delay its absorption, potentially prolonging the time it takes to experience the full effects.
  • Overall Health: Individual health conditions, liver function, and kidney function can affect how the body processes and eliminates sildenafil.
