Alternatives to Cialis (Tadalafil)

If you think Cialis may not be the right treatment option, then you can switch to Viagra (sildenafil), Levitra (vardenafil), or Spedra, which are approved alternative medications available in the UK for treating erectile problems. Before switching to other ED medications, you must consult a healthcare professional to see if they are suitable for you and to avoid side effects.

Who cannot take Cialis?

Cialis tablets are usually prescribed for men who are above 18 years of age and are suffering from erectile dysfunction. However, for some people, it may not be suitable for the following reasons:

  • An allergic reaction to any of the ingredients present in Cialis.
  • Taking medicines that contain nitrates.
  • Suffering from low blood pressure or high blood pressure, stroke, heart attack, leukaemia, multiple myeloma, Peyronie’s disease, chest pain, or serious heart and liver conditions.

How effective is Cialis (Tadalafil)?

Cialis (Tadalafil) can be effective for up to 36 hours, which is significantly longer than other ED medications. It is best to take Tadalafil on an empty stomach and avoid taking it with high-fat meals, as these can interfere with the absorption of the medication. Also, make sure you take one tablet at least 30 minutes before planning for sex.

What is the difference between Cialis and Tadalafil?

Tadalafil is the generic version, and Cialis is the branded version, both containing the same active ingredient. The effectiveness and side effects of both medications are the same. However, the price of Tadalafil is lower due to increased competition, as it is a generic drug which can be produced by many pharmaceutical companies.

What is Cialis?

Cialis (Tadalafil) is indicated for the treatment of erectile dysfunction in adult men. This occurs when a man cannot obtain or maintain a firm erection, suitable for satisfactory sexual activity. Tadalafil has shown a significant improvement in the ability to obtain a long-lasting penile erection suitable for sexual activity.

Cialis contains the active substance tadalafil, which belongs to a group of medicines called phosphodiesterase type 5 inhibitors. After sexual stimulation, tadalafil works by relaxing the blood vessels in your penis, allowing blood to flow into the penis. The result is an improvement in erectile function. Tadalafil will not help you if you do not have erectile dysfunction.

It is important to warn you that Cialis is not effective without sexual stimulation. Therefore, you and your partner should stimulate yourself in the same way that you would if you were not taking an erectile dysfunction medication.

How does it work?

Used to help with ED problems in men, the active ingredient in this ed treatment medication is Tadalafil. This is a phosphodiesterase type 5 (PDE5) inhibitor. After taking the impotence pill, the substance makes the blood flow through the penis. Ensures inhibition of the phosphodiesterase enzyme. During sexual arousal, the substance cyclic guanosine monophosphate (cGMP) is created. The muscle of the penis relaxes, and blood flows to the penis. An erection takes place. The phosphodiesterase enzyme breaks down substances that induce an erection. Cialis inhibits the effect of this enzyme while the substances that generate an erection remain active for that reason. This makes it easier to get an erection and maintain an erection for longer.

Furthermore, Cialis ensures the dilation of blood vessels. Also, blood flows easily into the penis. Tadalafil uses only work if there is sexual stimulation. Without this stimulation, the substance cannot generate an erection

What are the benefits of taking it?

Cialis, which contains the active substance Tadalafil, is a pill for erectile dysfunction. The treatment works in a similar way to Viagra or Levitra, but its effects remain active in the body for a much longer period of time; making Cialis a very popular choice for those men who are looking to enjoy sex spontaneously and thus avoid the need to take a pill in those intimate moments.

How do I use it and its dosage?

Always use this medicine exactly as your doctor or pharmacist has told you. If in doubt, consult your doctor or pharmacist again.

Cialis (Tadalafil) tablets are for oral administration only in men. Swallow the tablet whole with a little water. The tablets can be taken with or without food.

The recommended starting dose is one 10 mg tablet before sexual activity. If the effect of this dose is too weak your doctor may increase the dose to 20 mg. Tadalafil tablets are administered orally.

You can take the Cialis (Tadalafil) tablet at least 30 minutes before sexual activity.

Cialis (Tadalafil) can still be effective for up to 36 hours after taking the tablet.

You should not take Tadalafil more than once a day. Tadalafil 10 mg and 20 mg will be used before expected sexual activity and continued daily use is not recommended.

It is important to warn you that tadalafil is not effective without sexual stimulation. Therefore, you and your partner should stimulate yourself in the same way that you would if you were not taking an erectile dysfunction medication.

Drinking alcohol can temporarily lower your blood pressure. If you have taken or are planning to take tadalafil, avoid excessive alcohol consumption (blood alcohol level of 0.08% or higher), as it may increase the risk of dizziness when standing up.
