You receive your prescription after completing a questionnaire which you access under START CONSULTATION. A doctor evaluates and prescribes the treatment, if he finds it is right for you.

Product information

What is Sildenafil?

Sildenafil is used to treat erectile dysfunction in men. It is the active substance used in Viagra, the well-known ED medicine, which has been sold for over 20 years by the US-based manufacturer Pfizer. The medicine was originally developed to treat narrowing of the coronary arteries but proved to be significantly more effective in treating erection problems. Since 2013, this medication, under the name of its active ingredient (Sildenafil) has also been offered by numerous other manufacturers.

When is Sildenafil used?

Sildenafil falls into the category of the so-called PDE-5 inhibitors, which are used as remedies to treat erectile dysfunction.

If a doctor diagnoses erectile dysfunction, there is usually a malfunction of the enzyme PDE-5. This can occur in both older and younger men, but becomes more likely with age. The reasons for this malfunction differ from patient to patient and should be discussed individually with your doctor.

How does Sildenafil work?

During an erection, more blood flows into the penis than out. The enzyme phosphodiesterase-5 (PDE-5) rebalances this blood flow, ensuring the regression of the erection. In erectile dysfunction, PDE-5 suppresses the erection process from the beginning. Sildenafil is referred to as a PDE-5 inhibitor because it inhibits the effect of this enzyme. Circulation in the penis is preserved, ensuring a stable erection.However, keep in mind that Sildenafil is not a pleasure-enhancing medicine that triggers an erection on its own. The libido must first be stimulated to trigger an erection. Sildenafil then helps maintain the effect.

After ingestion, it takes 30-60 minutes, for the medicine Sildenafil to take effect. The effect usually lasts for about 4 hours , although the duration may vary slightly from user to user. During this time, with appropriate stimulation, men can achieve multiple erections and, accordingly, multiple ejaculations.

Which men can take Sildenafil in the UK?

Sildenafil is suitable for men of all ages and types in the UK, if erectile dysfunction has been diagnosed. Erectile dysfunction in different age groups has different causes. While impotence is often due to physical reasons in older men, it is caused by psychological reasons in young men. Sildenafil is effective in all of these cases.

Can Sildenafil be taken daily?

Only take Sildenafil if you plan on having sexual intercourse. Without sexual arousal, the treatment is ineffective. Since the effect occurs after about half an hour, it is not advisable to take Sildenafil prophylactically.

Sildenafil may also cause side effects and interact with other medicines. You should therefore consult with a doctor regarding how often you can take it.

What is the difference between Sildenafil and Viagra?

Sildenafil is the active ingredient in Pfizer's well-known erection treatment, Viagra. Since the medical patent for Viagra expired in 2013, other manufacturers can sell similar medicines with the same active ingredient. These duplicates are called generics and are usually named after the active ingredient: Sildenafil.

There are also alternatives to Sildenafil, which rely on different PDE-5 inhibitors. The medicines Cialis (based on the PDE-5 inhibitor Tadalafil), Levitra (with the active ingredient Vardenafil) and Spedra (with Avanafil) also treat erectile dysfunction and differ only slightly from medicines containing Sildenafil. Needless to say you can’t purchase Sildenafil over the counter.

What are generic medicines?

A generic medicine is a pharmaceutical product which is based on the same active ingredient as an existing medication. Generics may not be sold until the medical patent for the original product has expired. This takes 15 years. Generic medicines are subjected to the same strict controls as the original medicine. They may only differ from the model in terms of the excipients and the method of production. Manufacturers must prove that the generic has the same effect as the original.

Since 2013, generic versions of Viagra have entered the market. The advantage of generic medicines is that they are often less expensive than the original medicine. There are no research costs to develop these medicines which are passed onto the consumer.

Can you buy Sildenafil over the counter?

Sildenafil, the active ingredient found in these ED medicines, is not available over the counter. This type of medication can only be purchased with a prescription. A doctor’s consultation is therefore always necessary. This legal regulation serves primarily to protect the consumer. Taking Sildenafil may cause unwanted side effects that may pose a health hazard. In addition, always check which other medications you take in order to rule out dangerous interactions with other medications. Your doctor will check your overall health and decide if Sildenafil therapy is appropriate to treat erectile dysfunction without compromising your health.

Nevertheless, many cheap Sildenafil-based duplicate medicines are sold on the Internet without a prescription. These medicines are not subject to supervision and may therefore be very dangerous to your health. Buying and selling these medicines is illegal. With a doctor's prescription, you can be sure that the product you buy is legal and safe medicine.

If it is too time-consuming or uncomfortable for you to visit a doctor or to go to an inpatient pharmacy to buy erectile dysfunction tablets, then you are in the right place with DoktorABC. You can obtain the doctor's prescription via an online consultation. The issued medicine will then be sent to you conveniently via express shipping in discreet packaging.

How is Sildenafil dosed?

Sildenafil can be purchased from various manufacturers in 25 mg, 50 mg and 100 mg doses. Many men are recommended by their doctors to start with a dose of Sildenafil 50 mg. This way, the dose can be later adjusted (increased or decreased), if the 50 mg dose does not achieve the desired effect.

A dose of Sildenafil 25 mg is usually sufficient for younger men. Erection problems in this age group are often psychological, and even a low dose is sufficient to boost the sense of security, correcting the erectile dysfunction problems. Men over 70 should also take Sildenafil 25 mg to minimize the risk of unpleasant side effects.

In any case, never take more than Sildenafil 100 mg daily as the risk of side effects increases significantly.

Should I buy Sildenafil 25 mg, Sildenafil 50 mg or Sildenafil 100 mg?

The optimal level of Sildenafil dose depends on many factors, such as the degree of erectile dysfunction, age and weight. Ask your doctor which Sildenafil dosage is right for you. If the prescribed dose does not produce the desired effect, you can adjust your dosage at any time. Many men start with a Sildenafil 50mg dose and may later switch to Sildenafil 100mg or Sildenafil 25 mg after consulting the doctor.

How do I take Sildenafil?

The medicine is best taken about an hour before the planned sexual intercourse. This can be done before, after, or during meals. It should be noted, however, that rich food can have a negative effect on Sildenafil’s effectiveness or on the duration of its action. Therefore, take light meals rather than fatty, heavy foods to ensure that Sildenafil has the best effect.

Take Sildenafil whole and with plenty of fluids. The simultaneous consumption of alcohol is not advisable. Alcohol can weaken or even eliminate the effects of Sildenafil as it dilutes the blood. In addition, the consumption of alcohol increases the risk of unwanted side effects.

How long does the effect of Sildenafil last?

Sildenafil usually begins taking effect about 30-60 minutes after ingestion and has a duration of approximately 4 hours, with the duration varying from patient to patient.

Can Sildenafil be taken daily?

There are different opinions about whether Sildenafil should be taken daily. Some scientists believe that taking Sildenafil regularly helps fight erectile dysfunction. However, other studies indicate that daily intake of Sildenafil can cause unpleasant and harmful side effects.

Our doctors do not recommend taking this medicine daily. Various other ED medications, based on the active ingredient Tadalafil, have been developed for daily use. Medicines such as Cialis Daily from Lilly Pharma are available in low doses. These medications have been developed with the purpose of providing a solution for daily use.

Please consult a doctor to determine the dosage appropriate for you. Please also read the package insert for possible side effects and to rule out any interaction with other medications. You will find them on the respective product page.

What are Sildenafil's possible side effects?

Like most medicines, taking Sildenafil can cause unwanted side effects. This happens especially if the dose is too high or if Sildenafil is taken together with alcohol. In most cases, the side effects are mild and short-lived.

Very common (may affect more than 1 in 10 people):

  • Headache

Common (may affect up to 1 in 10 people):

  • Nausea
  • Flushing of face
  • Indigestion
  • Visual disturbances
  • Disruptions in color perception
  • Blurred vision
  • Light sensitivity
  • Hot flashes (with discomfort such as a sudden feeling of warmth in the upper body)
  • Nasal congestion and dizziness

When should I avoid taking Sildenafil?

Do not take Sildenafil in the following cases:

  • if you are allergic to Sildenafil, soy, peanuts, or any of the ingredients in the medicine
  • if you have had a heart attack or stroke, or if you have low blood pressure
  • if you are taking medicines for high blood pressure, nitrates or nitric oxide donors
  • if you have severe heart or liver disease
  • if you have certain rare eye diseases, such as retinitis pigmentosa, or have already had loss of vision due to arteritic anterior ischemic optic neuropathy (NAION)
  • if you take other medicines for erectile dysfunction simultaneously

It is important to become familiar with all sorts of side effects and interactions. For details, see the package insert. The package insert also explains in which cases a medical consultation is absolutely necessary. Contact our doctor or a local medical specialist.

Is Sildenafil effective when taken in combination with alcohol or on a full stomach?

Alcohol consumption negatively affects the ability to get an erection. For this reason, doctors recommend against taking Sildenafil together with alcohol. In addition, alcohol increases the medicine's side effects. In other words, the strength of your erection may be reduced and you may also encounter unpleasant side effects.

Fatty meals have the same effect. Medically speaking, light meals are preferable during treatment with Sildenafil, being healthier and more pleasant for the person ingesting the medicine.
