Sildenafil (Generic Viagra) Tablets

Sildenafil is an effective treatment for ED, but this does not mean it works every time. It usually takes an hour to work, so you should take it an hour before sex. It does not cure ED, but it can help you to get and keep an erection. You may need to take it a few times before you see the best effect.

Sildenafil is just as effective as Viagra because sildenafil and Viagra both contain the same active ingredient (sildenafil) and work the same way. Viagra is the brand name version of sildenafil, and they both have the same amount of sildenafil in each tablet and work for the same amount of time.

Sildenafil lasts for around 4 hours after you take it. You can have more than 1 erection during this time, but only if you are sexually aroused.

If you think sildenafil is not working, you can speak to your doctor about increasing your dose. You should also follow the instructions on this page to make sure you are taking sildenafil for the best effect. You may need a different ED treatment.

You cannot buy sildenafil without a prescription, but you can get it online with ZAVA. Sildenafil is available through the NHS. You’ll need to book an appointment with your doctor to get a prescription.

Viagra Connect (50mg sildenafil) is available without a prescription, as it is an over the counter version of Viagra that you can buy online or in a pharmacy.

Sildenafil cannot make you last longer in bed. When you are aroused, sildenafil can help you get and maintain an erection but it cannot stop you from ejaculating.

Premature ejaculation is when you ejaculate too early during sex. If you find you are ejaculating within the first few minutes of sex, there are other treatments you can try, such as Emla cream or Priligy tablets.

You can take sildenafil on an empty stomach but it is not always necessary. Taking sildenafil with food or after eating a meal may cause it to work more slowly.

Yes, sildenafil is safe as long as you follow your doctor’s instructions and take it properly once it has been prescribed to you. For example, you should not take more than the recommended dose or take sildenafil with another erectile dysfunction medication.

You should not take sildenafil if you:

• take medication for chest pain (nitrates)
• have ever had an allergic reaction to sildenafil or Viagra
• have low blood pressure
• have heart or kidney problems
• have recently had breast cancer or a stroke
• have a rare inherited eye disease

Additionally, speak to a doctor beforehand if you have:

• a stomach ulcer
• a bleeding disorder, like haemophilia
• sickle cell anaemia
• multiple myeloma
• any deformities in your penis, such as a significant bend or curve (Peyronie's disease)

When you request sildenafil through ZAVA, we will ask about these conditions so our doctors can check that sildenafil is safe and suitable for you.

You should always read the patient information leaflet included with any prescribed medication before taking it for the first time.

Yes, sildenafil and Viagra are the same. They both contain the same active ingredient, sildenafil, and work in the same way. Sildenafil is simply the generic, unbranded version of Viagra. Generic medications are typically less expensive than branded medications.

The other key difference between sildenafil and Viagra is their appearance. Viagra pills have a distinct blue, diamond shaped appearance while generic sildenafil pills are white and round.

Yes, you can take sildenafil daily but you must not take more than 1 pill a day.

You can cut or split a sildenafil pill in half, if you wish. For example, if you can’t swallow a whole pill or if you only want to take half a pill at a time.

However, you should:

• check this is safe to do with your doctor beforehand
• use a pill splitter or pill cutter device to do this properly and safely, instead of a knife or scissors
• split one pill at a time close before you plan to take it
• store any split pills in a sealed container away from sunlight

Please note, not all pills or tablets can be split or cut in half. This includes those that are scored and appear like they can be split.

You should not crush a sildenafil pill when taking it. Instead, swallow it whole without crushing or chewing it.

You should take sildenafil 1 hour before you plan to have sex.

The effects of sildenafil last 4 to 5 hours. For the best results, you should:

• take sildenafil on an empty stomach, or avoid fatty meals
• avoid drinking alcohol, or restrict yourself to 3 units of alcohol only that day
• avoid grapefruit juice

No, there is no way to make sildenafil work faster. This includes chewing a pill.

Yes, but you should limit yourself to 3 units of alcohol on any day you take sildenafil. Drinking large amounts of alcohol can make it difficult to get an erection, whether you take erectile dysfunction medication or not.

As a guide, 3 units of alcohol is equivalent to either:

• 3 single shots of gin, rum, vodka, whisky, tequila or sambuca (25ml, ABV 40% per shot)
• 1 pint of higher strength lager, beer or cider (ABV 5.2%)
• 1 large glass of red/white/rosé wine (250ml, ABV 12%)

Sildenafil can cause a small drop in blood pressure because it works by relaxing blood pressure in your arteries.

If you have low blood pressure (hypotension) or you take medication for chest pains (nitrates), it is not safe to take sildenafil. This is because your blood pressure can drop too low as a result.

A doctor will check that sildenafil is safe for you by asking you about any medical conditions you have or medications you’re taking before prescribing it to you. If you request sildenafil through ZAVA, one of our doctors will check this as part of your online consultation.
