1. What is Tadilecto and what is it used for
Tadilecto is a medicine used for adult men with erectile dysfunction. This is a condition where a man cannot achieve or maintain an erection sufficient for satisfactory sexual performance. Tadilecto has been shown to significantly improve the ability to achieve an erection sufficient for satisfactory sexual performance. Tadilecto contains the active substance tadalafil, which belongs to a group of medicines called phosphodiesterase type 5 inhibitors. After sexual stimulation, Tadilecto helps to relax the blood vessels in the penis, allowing blood to flow into the penis. As a result, the erection is improved. Tadilecto does not help patients who do not have erectile dysfunction. It is important to note that Tadilecto does not work without sexual stimulation.
2. Important information before taking Tadilecto
When not to take Tadilecto
- if you are allergic to tadalafil or any of the other ingredients of this medicine (listed in section 6),
- if you are taking organic nitrates or other nitric oxide donors, such as amyl nitrite. This is a group of medicines ("nitrates") used to treat angina pectoris (chest pain). Tadalafil has been shown to increase the effects of these medicines. If you are taking nitrates in any form or are unsure, you should tell your doctor.
- if you have severe heart disease or have had a heart attack in the last 90 days,
- if you have had a stroke in the last 6 months,
- if you have low blood pressure or uncontrolled high blood pressure,
- if you have ever had loss of vision due to non-arteritic anterior ischemic optic neuropathy (NAION), also known as "stroke of the eye",
- if you are taking riociguat. This is a medicine used to treat pulmonary hypertension (i.e., high blood pressure in the lungs) and chronic thromboembolic pulmonary hypertension (i.e., high blood pressure in the lungs caused by blood clots). It has been shown that phosphodiesterase type 5 inhibitors, such as tadalafil, increase the effects of this medicine. If you are taking riociguat or are unsure, you should tell your doctor.

3. How to take Tadilecto
This medicine should always be taken exactly as your doctor or pharmacist has told you. If you are not sure, you should ask your doctor or pharmacist. Tadilecto tablets are for oral use only, for men. The tablets should be swallowed whole with a small amount of water. The tablets can be taken with or without food.

You should not take Tadilecto more than once a day.
Taking Tadilecto once a day may be beneficial for men who intend to have sexual activity twice a week or more frequently.

You should arrange foreplay, just as you would if you were not taking erectile dysfunction medicines.
Drinking alcohol may affect your ability to achieve an erection and may temporarily lower your blood pressure. If you have taken Tadilecto or plan to take it, you should not drink large amounts of alcohol (blood alcohol level of 0.08% or higher), as this may increase the risk of dizziness when standing up.
If you take more Tadilecto than you should

If you forget to take Tadilecto
You should take the dose as soon as you remember, but do not take a double dose to make up for a forgotten tablet.
