How effective is Viagra?

Since its release, Viagra has proven effective for over 80% of men in improving their ability to achieve and maintain an erection. It has shown to be rapidly absorbed by the body, and in studies, men noted a significant positive physical response.

How does Viagra (Sildenafil) work?

Viagra inhibits an enzyme called PDE5. This acts on cGMP, a substance that regulates blood flow to the penis. The tablet relaxes the arteries that supply blood to the penis, allowing for increased blood flow to this body part resulting in getting and maintaining an erection. Contrary to widespread belief, the treatment does not promote spontaneous erections and requires you to be sexually aroused.

How long does it take Viagra to work?

Viagra (Sildenafil) quickly absorbs into the body. The effects are usually noticeable within 30 minutes and can last 4 to 5 hours. According to a study, 70% of the men achieved an erection in 30 minutes, and more than 80% achieved an erection in 45 minutes. So, it is better to take the medicine 1 hour before you want to have sex. Some factors may affect the length of time Viagra takes to work, including:

  • What food you have eaten
  • Amount of alcohol you have consumed
  • How aroused you are

Viagra alternatives

There are a number of drug-based erectile dysfunction treatments available. These include:

What dose of Viagra should I choose?

Viagra comes in tablet form. The normal dose for Viagra is 50mg. Your GP may recommend a lower dose of 25mg if you are 65 years or older.

You should never take more than one tablet within 24 hours. Do not exceed the maximum dose of 100mg, as it will increase the risk of side effects. You can contact your doctor or our pharmacist for more information.

How should I take Viagra (Sildenafil)?

Swallow a Viagra tablet whole with water or juice (do not use grapefruit juice) one hour before sex. The tablet works best when taken on an empty stomach. When consumed with a meal, it may take longer or decrease its effectiveness.

Side effects

As with any medication, there are a number of possible side effects to consider when taking Viagra which include the following: 

Common side effects:

  • Headaches
  • Muscle aches or pains
  • Flushing
  • Stomach upset
  • Dizziness
  • Hot flush
  • Indigestion
  • Feeling sick (Nausea)
  • Nasal congestion
  • Rash
  • Heartburn
  • Colour tinge to vision
  • Blurred vision
  • Visual disturbances

Severe side effects:

  • Priapism
  • Sudden decrease or loss of vision in one or both eyes
  • Serious skin reaction
  • Chest pains
  • Allergic reaction
  • Seizure or fits

In rare cases, Viagra can cause a potentially dangerous condition known as priapism, where an erection can last more than 4 hours and cause long-term damage if left untreated. This mostly occurs when you mix Viagra with certain medications or illegal drugs; if this happens, you must seek medical care immediately.

Though ED treatments are safe for the majority of men, patients suffering from cardiovascular disease should consult a physician before using them. You can learn more about possible side effects by speaking to your GP or contacting our pharmacist at Click Pharmacy.
