About sildenafil
Sildenafil belongs to a group of medicines called PDE5 inhibitors, which are used in erectile dysfunction treatment. It stops a specific enzyme in your body called phosphodiesterase type-5 (PDE5) from working too quickly. This makes it easier to get and keep an erection during sex. If you suffer from a disease of the heart or blood vessels, talk to your doctor before using this or related medicines.

How effective is sildenafil?
Sildenafil is helpful for patients with severe erectile dysfunction. It can also help improve your relationship with your sexual partner.
How much sildenafil should I take?
Your dose of sildenafil depends on what you want to gain. You may want to take one tablet daily. Instead, you may want or need a lower dose if you:
-
Have side effects
-
Are older
- Have underlying health issues
Whatever you need, different dosages are available to suit your own situation.
How does sildenafil work?
Sildenafil tablets stop the effects of the natural chemical PDE5. This relaxes the muscles in the veins that carry blood to the penis. As a result, this increases blood flow to the penis, helping you get an erection. However, the tablets don't cause erections without stimulation and don't affect your sexual desire. You must be sexually aroused to get an erection using sildenafil.
PDE5 inhibitors don't treat the underlying causes of erectile dysfunction. These causes can include:
-
Physical problems, such as diabetes and high blood pressure.
- Psychological issues, such as anxiety and depression.
To find out why you have erectile dysfunction, talk to a doctor.
Sildenafil ingredients
The active ingredient in sildenafil tablets is sildenafil citrate. It comes in doses of 25mg, 50mg or 100mg per tablet.
The inactive ingredients are:
-
Microcrystalline cellulose
-
Anhydrous dibasic calcium phosphate
-
Croscarmellose sodium
-
Magnesium stearate
-
Hypromellose
-
Titanium dioxide
-
Lactose monohydrate
-
Triacetin
Alternatives to sildenafil
Sildenafil is a common medicine used to treat erectile dysfunction. Other options include:
-
Tadalafil (Cialis)
This is a long-lasting erectile dysfunction medicine. Its effects can last for up to 36 hours.
-
Vardenafil (Levitra)
This is similar to sildenafil. However, it may work better for some men, especially after meals.
-
Avanafil (Spedra)
This is a newer erectile dysfunction drug that works faster. It may also have fewer side effects.
What is the difference between sildenafil and Viagra?
Sildenafil and Viagra are the same. In fact, sildenafil is the active ingredient in Viagra. This means sildenafil is generic Viagra. Both are sold in packs of 4 or 8 tablets and both come in strengths of 25mg, 50mg and 100mg.
Patient Information Leaflet
Always read the patient information leaflet before starting your treatment. The patient information can be found here.
What sildenafil dosage should I choose?
Sildenafil comes in tablet form. Never take more than one sildenafil tablet within 24 hours.
Sildenafil is available in three dosages: 25mg, 50mg and 100mg. The 100mg tablets can be more effective. However, the 25mg tablets can cause fewer side effects.
To learn more about how much sildenafil to take, speak to your doctor. You can also book a time to speak with one of our informed healthcare professionals at Click Pharmacy.
How should I take sildenafil?
Sildenafil usually works best when you take one tablet around an hour before sex. This is enough time for it to work. However, the tablets can be taken anywhere between 4 hours and 30 minutes before sex. For best results, take sildenafil tablets on an empty stomach and without alcohol. If you do eat before taking the tablets, a high-fat meal will reduce their effect. Sildenafil lasts between 4 and 6 hours.
Sildenafil side effects
As with all medicines, while taking sildenafil tablets, you may experience side effects. The most common include:
-
Headaches
-
Heartburn
-
Flushed skin
-
Stuffy nose
-
Nausea
-
Vomiting
- Diarrhoea
Never take sildenafil with nitrates. This can cause a serious and potentially fatal drop in blood pressure.
Taking too much sildenafil can be dangerous and will not increase the tablets' intended effect. Also, overdose can result in side effects, such as:
-
Chest pain
-
Irregular heart rate
-
Feeling sick
- An erection that will not go away
Without treatment, a long-lasting erection can lead to permanent damage and future problems achieving an erection. So, if your erection will not go away, seek medical help right away.
For further information, or if you're not happy with the effects of sildenafil, contact your GP or our specialists.
Sildenafil warnings
Before taking sildenafil, talk to your doctor or pharmacist if you have (or have had) any of these conditions:
-
Heart conditions, including a heart attack or stroke within the last 6 months.
-
High or low blood pressure.
-
Chest pain or irregular heart rhythms.
-
Liver or kidney issues.
-
Blood disorders, such as sickle cell anaemia, leukaemia or bone marrow cancer.
-
Deformity of the penis, such as Peyronie's disease.
-
Eye conditions, such as retinitis pigmentosa or other serious visual problems.
- Bleeding disorders or a history of stomach ulcers.
Also, talk to a doctor or pharmacist if you're taking medications such as nitrates (often used for chest pain) or nitric oxide donors. Taking these with sildenafil can dangerously lower your blood pressure.
Tell your doctor or pharmacist if you're taking other treatments for erectile dysfunction. In addition, tell them if you're taking medication for:
-
HIV
-
Blood pressure
- Prostate problems
Your doctor can assess whether sildenafil is safe for you. Sildenafil may cause blood pressure issues if you take the tablets with other medications.
Can I drink alcohol while taking sildenafil?
Avoid drinking alcohol while taking sildenafil. Both alcohol and sildenafil lower blood pressure, so this could make you feel dizzy and faint.
Why is sildenafil cheaper than Viagra?
Viagra lost its UK patent in 2013. After that, new, similar drugs were created, including sildenafil. Sildenafil contains the same active ingredient as Viagra and is a generic version. It is sold at a lower price.
How long do sildenafil tablets last?
Sildenafil typically lasts for 4 to 6 hours, giving you an erection when you are sexually aroused. Sometimes, it may work for longer. However, its effects usually decrease after a few hours. This depends on factors such as health, dosage and metabolism.
What if sildenafil doesn't work?
When you first take sildenafil 100mg, 50mg or 25mg, the tablet may not work as well as you expected. Doctors recommend taking sildenafil on 8 separate occasions before increasing the dose or trying a different erectile dysfunction tablet. Factors such as diet and mood can affect how well it works. If sildenafil still doesn't work, talk to your doctor or pharmacist about other treatments. These can include Cialis, Levitra or Spedra. Some men may respond better to different options.
Sildenafil vs. tadalafil: Which is better?
Sildenafil (Viagra) and tadalafil (Cialis) are both PDE5 inhibitors used in the treatment of erectile dysfunction. However, Cialis lasts longer, making it more flexible. Here's how they compare:
- Sildenafil (Viagra): Lasts 4–6 hours and works best on an empty stomach. This makes sildenafil ideal for planned use.
- Tadalafil (Cialis): Lasts up to 36 hours, so there's less need to plan ahead. Cialis can be taken with or without food and also comes in a daily low-dose version.
Which is better depends on your needs. For more flexibility, Cialis might be a better choice. While for planned use over short periods, you might prefer to take Viagra.
Is sildenafil safe?
Yes, sildenafil is safe when used as directed. It's approved for treating erectile dysfunction and has no known long-term side effects. However, talk to your doctor if you have medical conditions or are taking other medications. These tablets may interact with some other treatments. Avoid unlicensed alternatives, as they can be harmful. If you have any severe side effects, seek medical help straight away. Always read the patient information leaflet.
Can women take sildenafil?
Sildenafil is primarily used to treat erectile dysfunction in men. It is not approved for women. While the tablet may be prescribed for other conditions, its effects on women are not well-studied. It may cause side effects. Women should talk to a doctor before considering sildenafil.
How can I get the best results from sildenafil?
To get the best results from sildenafil, take the tablets on an empty stomach about one hour before sexual activity. Avoid large, high-fat meals, and take sildenafil without drinking alcohol. Both can affect how well the tablet works. Following these tips can improve your experience with the tablets.
Can I use sildenafil with other erectile dysfunction treatments?
No. Sildenafil cannot be combined with other erectile dysfunction treatments, as there is an increased risk of side effects. Wait at least 24 hours between doses. For safety, tell your doctor about all medications you are taking. Avoid unlicensed alternatives. Use our registered online pharmacy to make sure you're buying the real medicine.
