Product information

What is Tadalafil?

Tadalafil is an Erectile Dysfunction treatment that inhibits the enzyme called PDE5, which is usually responsible for the inability of achieving or maintaining an erection. Once the production of this enzyme is hindered or retained to a normal level, stronger bloodflow into the erectile tissue leads to dilation of blood vessels. This results in a firm erection and enables the user to engage in sexual intercourse.

Tadalafil is an unbranded, or generic, version of Cialis tablets – a well-known medication for Erectile Dysfunction. Tadalafil increases the blood flow to the penis, helping to achieve and maintain a healthy erection. Take up to one pill per day, with or without food, at least half an hour before sexual activity. Tadalafil is the main active ingredient in Cialis and as a generic medication, is less expensive than Cialis.

When are Tadalafil tablets used?

Tadalafil tablets are used when Erectile Dysfunction has been diagnosed. ED is only diagnosed if a man has difficulty getting or keeping a firm enough erection to be able to have sex on a regular basis. An occasional difficulty is considered to be in the realm of normal and does not warrant treatment.

How does Tadalafil work?

Tadalafil helps to increase the blood flow to the penis by preventing the chemical Phosphodiesterase type 5 from acting within the human body. The medicine keeps blood vessels dilated for some time, which makes it easier for blood to reach the penis. As a result, a man will get and maintain a healthy erection for some time.

Tadalafil takes effect within 30-60 minutes of being taken and is effective for up to 36 hours. It is important to remember that Tadalafil tablets will not provide any effect without sexual stimulation. In order to get and maintain an erection, a man has to be stimulated sexually. This is because Tadalafil enhances the chemical processes responsible for erection, but it can’t fully replace these processes.

How long does the effect of Tadalafil last?

Tadalafil is effective for up to 36 hours. The effectiveness varies slightly for each man, so you may feel the effectiveness for slightly longer or slightly less time.

What is the difference between Tadalafil vs. Cialis?

When comparing Tadalafil vs. Cialis, it is important to note that Tadalafil is the active ingredient in Cialis. Since Tadalafil is a generic version, its price is not controlled by a single manufacturer and it is less expensive to buy. Tadalafil is tested and proven to have the same overall effectiveness as its counterpart.

What is a generic medicine?

A generic medicine has the same dosage, intended use, effects, side effects, route of administration, risks, safety, and strength as the original branded version. Generic versions are less expensive because the company that produces them doesn’t have the added costs of development and marketing. Tadalafil generic medicine has the same pharmacological effects as the brand-name version Cialis.

Can I buy Tadalafil without a prescription?

There are criteria for using Tadalafil and men with certain medical conditions should not use it. That’s why you can only buy original Tadalafil with a prescription. When you use the DoktorABC service to order Tadalafil online, a doctor examines your medical history and prescribes the medication if you meet the criteria.

What Tadalafil dosage can I buy?

Tadalafil dosage is 10mg, 20mg and 5mg.

  • Tadalafil 10mg:

Tadalafil 10mg is generally the first dosage prescribed for Erectile Dysfunction. For patients with severe renal impairment, 10mg is the maximum recommended dose.

  • Tadalafil 20mg:

When Tadalafil 10mg does not produce an adequate effect, a doctor can prescribe Tadalafil 20mg.

  • Tadalafil 5mg:

This dose is intended for regular daily intake and suited for those who would like to be ready at any time. In addition to the treatment of Erectile Dysfunction, Tadalafil 5 mg is used for treatment of the signs and symptoms of benign prostatic hyperplasia in adult men.

How to take Tadalafil?

Take one pill of Tadalafil per day – and no more than one. Within a 36-hour period, do not take any other medications for ED. You can take a Tadalafil tablet with or without food. A tablet should be taken orally with a glass of water and swallowed whole.

Can I take Tadalafil daily?

The maximum Tadalafil dosage is one per day. The recommended dose is as needed, prior to anticipated sexual activity. Only the Tadalafil 5mg is taken regularly. For prostatic hyperplasia, it should be taken daily at approximately the same time of day without regard for anticipated sexual activity.

Does Tadalafil lose its effectiveness when taken regularly?

Tadalafil tablets do not lose their effectiveness over time, except in rare cases. Decreased effectiveness may be a sign of underlying medical issues, such as high blood pressure, high cholesterol, poor control of diabetes and weight gain.

Our doctors at DoktorABC will advise the proper dosage for you, after you complete the short questionnaire under START ORDER and the medication is found suiting for you. The medication for your treatment gets sent to your chosen addres the following day. If you want to find out more about the treatments, consult our doctors free of charge via chat.

What are the side effects of Tadalafil?
