About Sildenafil tablets

Sildenafil (generic Viagra) temporarily increases blood flow to your penis when you're sexually aroused. When you feel sexually excited, a chemical called cGMP is released, relaxing the smooth muscles in the penis. This relaxation lets more blood flow in, leading to an erection.

Remember, It doesn't boost your sexual desire. If you're dealing with low libido, talk to your doctor or pharmacist for advice.

It contains Sildenafil citrate, the active ingredient grouped under phosphodiesterase 5 (PDE5) inhibitors. These medicines prevent an enzyme called phosphodiesterase type-5 from working too quickly, which helps to increase blood flow to the penis when you are sexually stimulated, resulting in a firmer and longer-lasting erection.

What should you remind before taking Sildenafil?

  • ⚠️ See a doctor before taking Sildenafil, especially if you have any underlying health conditions, including heart problems, high blood pressure, or liver or kidney disease.
  • ❌ Do not take Sildenafil with nitrates (medications for chest pain) as it can cause a dangerous drop in blood pressure.
  • ⚠️ Inform your doctor about all medications you take to avoid potential interactions.

is sildenafil viagra?

Yes, sildenafil is the active ingredient in Viagra. Viagra is a brand name for sildenafil citrate, a medication used to treat erectile dysfunction (ED) by increasing blood flow to the penis to help achieve and maintain an erection. It is also marketed under other brand names, such as Revatio, for the treatment of pulmonary arterial hypertension.

How to take Sildenafil 100mg/50mg/25mg?

How to take Sildenafil? Take one tablet around 25 mins. 1 hour before having sex. Heavy meal can affect Sildenafil absorption, so take it on an empty stomach or with a light meal for the best results.

Sildenafil is available in three strengths: 100mg, 50mg, and 25mg. However, a higher dose isn't necessarily better. The most effective dose depends on factors like age, health, severity of ED, and other medications.

Doctors typically prescribe a lower dose to reduce side effects and evaluate effectiveness. They only increase it if necessary and safe. Always stick to your doctor's advice.

They will determine the best dose for balancing effectiveness and safety based on your unique situation. For optimal results, follow these guidelines:

Dosage: Take one tablet approximately one hour before sexual activity.
Consumption: Swallow the tablet whole with water. Do not crush or split the tablet.
Timing: It can be taken with or without food, but high-fat meals may delay its onset.
Frequency: Do not take more than one tablet in a 24-hour period.
Alcohol: Limit alcohol consumption, as it can reduce the effectiveness of the medication.
Side Effects: Higher doses increase the likelihood of side effects.

Sildenafil effectiveness

Sildenafil Citrate, or cheap Viagra, people also called the blue pill in the UK, successfully treats ED in approximately two-thirds of cases. Still, its effectiveness may decrease if you have had a big meal or consumed more than 1-2 units of alcohol.

Study confirmed that 25 mg/50 mg and 100mg of Sildenafil tablets significantly enhanced erection quality and treatment satisfaction, reduced anxiety levels, and improved the overall sexual experience compared to the placebo.

Remember that Sildenafil may not be effective on the first try. Use it at least eight times before considering alternative ED medications.

If 50mg isn't effective, consider sildenafil 100mg for better results. If 50mg causes side effects, switch to 25 mg; it's still effective for treating erectile dysfunction.

How quickly does Sildenafil work?

sildenafil 100mg ukSildenafil tablets typically take 30 to 60 minutes to work, although it can take up to 2 hours for some people. The highest amount of sildenafil citrate in your bloodstream happens around 60 minutes after you take it. Still, you might begin feeling its effects in approximately 25-30 minutes.

But remember, it won't give you an auto erection on its own—you need to be sexually aroused for it to go into action. So, plan to take it about an hour before you want to have sex. The effects can last for around 4 to 6 hours, but it varies from person to person.

How long do Sildenafil effects last?

Commonly, the effects of Sildenafil last 2-6 hours. Very rarely, the effects may persist for up to 10 hours, giving you ample time to engage in sexual activity with improved erectile function.

It won't keep it up indefinitely after sex. The results of Sildenafil gradually fade over time and will be gone within a day.

What if Sildenafil 100mg/50mg/25mg doesn't work for me?

For some patient, it may take a few attempts to see the effects of Sildenafil tablets. If Sildenafil 100mg/50mg/25mg doesn't work for the first time, don't give up. Try at least 8 separate occasions. Sometimes, your body needs time to get used to the medication before it starts working effectively.

Alcohol consumption, meals, and mood can influence how well it works. So, consider trying Sildenafil in various situations to find what works best.

If you find that it's still not effective after attempting it eight times, it's advisable to consult with your doctor to consider adjusting your dosage strength or switching to alternative ed treatments.

Is Sildenafil safe?

Sildenafil is an FDA-approved and safe medication when used as directed. Still, it's important to note that it can interact with certain medicines.

Sometimes, these interactions can pose a risk and potentially harm health. However, there's no evidence of long-term side effects. However, if you have certain health conditions, please consult your doctor before taking it.

❌ Who shouldn't take Sildenafil?

Don't take Sildenafil if you have:

  • Certain anatomical penis deformities
  • Eye problems (excluding poor vision)
  • Sickle-cell anemia
  • Low blood pressure
  • An allergy to its ingredients
  • Recent heart issues like heart attack or stroke
  • Angina
  • Liver or kidney problems
  • Certain cancers or bleeding disorders
  • Stomach ulcers


  • Where can I buy Sildenafil?

    Online pharmacies, such as Ashcroft Pharmacy UK, offer Sildenafil following an online consultation. We stock various brands with no clinical differences among them.

  • How can I get the best results from Sildenafil?

    To get the best results from Sildenafil tablets, it's important to follow the directions carefully. This includes taking it on an empty stomach and not drinking too much alcohol. Sildenafil or Viagra works faster when taken on an empty stomach.

    Taking it after eating might take longer to work, especially if you've eaten a large, high-fat meal. This is because food can slow down the absorption of the medication into your bloodstream.

  • Which Sildenafil strength is recommended for first-time use?

    If you're using Viagra for the first time, starting with 50mg is usually recommended. This dose is adequate for most men and offers a good balance between desired effects and potential side effects.

    Depending on your health and any other medications you're taking, a doctor might suggest starting with 25mg in some cases.

  • Is sildenafil as good as Viagra?

    They're very similar, but Viagra costs more and Sildenafil at a lower cost.

  • If Sildenafil doesn't work?

    For the first attempt, whether it's sildenafil 100mg, 50mg, or 25mg, it may not be as effective as expected. It's not necessarily that the medication isn't working; various factors such as food and mood can affect its efficacy. Give it a chance by trying it at least eight times in different environments.

  • Should I use sildenafil with other ED medications for increased effectiveness?

    Sildenafil contains all the proven ingredients to address ED problems, so combining it with other ED treatments isn't necessary. It's advisable to wait 24 hours between doses. Why? It's not recommended to mix Sildenafil with other ED treatments due to several reasons:

    Firstly, both Sildenafil and other ED medications work similarly by affecting blood flow. When taken together, these effects can be amplified, leading to a higher risk of side effects such as headaches, dizziness, flushing, and indigestion.

    Additionally, there's a risk of potential interactions between Sildenafil and other ED meds, which can cause unforeseen complications.

    That's why it's important to let know your doctor about all current medications and supplements you're taking. Furthermore, using multiple medications for ED can result in confusion and difficulty managing dosages.

    This increases the risk of unintentionally taking too much medication, which can be dangerous.

  • How often can I take Sildenafil 100mg?

    DO NOT take more than one erectile dysfunction treatment within a 24-hour period, even though Sildenafil 25mg tablets can generally be used as needed for treating ED.

    Additionally, it's advised not to exceed 100mg per day and not to use Sildenafil for more than four days per week.

  • Can women take sildenafil?

    Sildenafil only treats ED, not libido. Don't use it if you're a woman, as it might cause unwanted effects.

  • Can I take 2 sildenafil tablets at once?

    No. The maximum sildenafil dose is 100mg; instead of taking two 50mg tablets, switching to the 100mg tablet is recommended and only taking one. Taking higher doses than the maximum dose will not help you achieve a better erection.

  • Can I take two 25mg tablets together while the maximum dosage is 100mg?

    It is generally not advisable to take two 25mg Sildenafil tablets together, even though the total (50mg) is under the maximum recommended dosage (100mg).

    Sildenafil 25mg is specifically intended for individuals aged 65 years or older, with the recommended treatment regimen being one tablet per day. Exceeding the prescribed amount may increase the risk of side effects.


  • Sildenafil vs. Tadalafil: Which is Better?

    Sildenafil (Viagra) and tadalafil (Cialis) are both phosphodiesterase type 5 (PDE5) inhibitors used to treat ED, but they have different characteristics that might make one more suitable for you than the other.

    Sildenafil (Viagra)

    • Duration: Lasts for about 4-6 hours.
    • Onset: Takes about 30-60 minutes to start working.
    • Usage: Best taken on an empty stomach for quicker onset.

    • Usage: Can be taken with or without food. Also available in a daily low-dose version.

    Which is Better?

    • Spontaneity: Tadalafil allows for more spontaneity due to its longer duration.
    • Side Effects: Both have similar side effects, but some users may tolerate one better than the other.
  • Can tadalafil/Cialis daily and sildenafil/Viagra be taken together?

    No, using them together is not advised, as they can interact with each other and cause unwanted side effects.

  • How can I naturally address erectile dysfunction (ED)?

    Tips include:

    • Diet changes, such as reducing alcohol and fat intake
    • Reducing stress levels
    • Quit smoking
    • Talk to your doctor about other health conditions, such as heart disease or high blood pressure.
