How long does Viagra take to work?

The effects of Viagra will vary from person to person. As a general rule, Viagra is thought to start working in most people from around 30 minutes after taking the drug.

It is important to understand that taking Viagra tablets alone will not cause an erection. Viagra must be taken in combination with some form of sexual stimulation (visual, tactile or otherwise) in order for an erection to occur.

There are some factors that affects how long Viagra lasts for?

The effectivity of Viagra, or how long Viagra will last for, depends on a number of things. These can include:

Age:- Men over 65 years of age will find that the tablet stays in their body for longer because the body’s metabolic system tends to slow down with age. Essentially, this means that Viagra’s effects can last longer the older you are.

Alcohol:- Drinking alcohol decreases the blood flow to the penis making it harder to get and keep an erection. A glass of wine or a single beer is usually fine, but more than 2 units of alcohol will increase the risk of negative side effects and will make it much more difficult to maintain an erection.

Health:- If you have liver or kidney problems, Viagra’s effects could last for longer. This is because the tablet will take longer to be broken down by your body, so you must always tell the doctor if you suffer from any of these.

Dosage:- Viagra comes in tablets ranging in dose from 25mg to 100mg. As a rule of thumb: the higher the dose, the more effective and long-lasting the effects will be, but your prescribing doctor will decide which dosage is appropriate in your situation.

Drug interactions:- Certain medicines can alter how long the effects of Viagra will last. This includes medicines such as the antibiotic rifampicin (used to treat tuberculosis). Always discuss your full medical history and any medicines you are currently taking with your prescribing doctor so that they can ensure it is safe for you to take Viagra.
