Tadalafil STADA – Tadalafil uses, dose and side effects


5 mg film-coated tablets

What Tadalafil STADA is and what it is used for

Tadalafil Stada contains the active substance tadalafil which belongs to a group of medicines called phosphodiesterase type 5 inhibitors.

Tadalafil Stada 5 mg is used to treat adult men with:

  • erectile dysfunction. This means that a man cannot get, or maintain, a hard and erect penis, sufficient for sexual intercourse. Tadalafil has been shown to significantly improve the ability to have a hard and erect penis, sufficient for sexual intercourse. Tadalafil Stada works during sexual stimulation by relaxing the blood vessels in the penis, so that blood can flow in. This results in improved erectile function. If you do not have erectile dysfunction, Tadalafil Stada will not help. It is important to remember that Tadalafil Stada has no effect if you are not sexually stimulated. The need for foreplay for you and your partner is the same as when you have not taken any medication for erectile dysfunction.
  • urinary tract symptoms are associated with a common condition called benign prostatic hyperplasia. This is when the prostate gland becomes larger with increasing age. Symptoms include difficulty passing water, a feeling of not being able to empty the bladder, and having to pass water more often, even at night. Tadalafil Stada improves blood flow and relaxes the muscles of the prostate and bladder, which can reduce symptoms of benign prostatic hyperplasia. Tadalafil has shown an effect on these urinary tract symptoms as early as 1-2 weeks after starting treatment.

Tadalafil contained in Tadalafil Stada may also be approved to treat other conditions not mentioned in this product information. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.

What you need to know before you use Tadalafil STADA

Do not use Tadalafil STADA

  • if you are allergic to tadalafil or any of the other ingredients of this medicine (listed in section 6)
  • if you take medicines containing organic nitrates or nitric oxide donors such as amyl nitrite. These medicines (“nitrates”) are used to treat angina (chest pain). Tadalafil has been shown to increase the effect of these drugs. If you are taking any form of nitrates or if you are not sure, talk to your doctor
  • if you have a serious heart condition or have recently had a heart attack within the last 90 days.
  • if you have recently had a stroke within the last 6 months.
  • if you have low blood pressure or uncontrolled high blood pressure.
  • if you have ever lost your sight due to non-arteritic anterior ischemic optic neuropathy (NAION), the so-called ‘stroke in the eye’.
  • if you take riociguat. This medicine is used to treat pulmonary arterial hypertension (ie high blood pressure in the lungs) and chronic thromboembolic pulmonary hypertension (ie high blood pressure in the lungs due to blood clots). PDE5 inhibitors, such as tadalafil, have been shown to increase the blood pressure-lowering effect of this drug. If you are taking riociguat or if you are not sure, talk to your doctor.

Warnings and precautions

Talk to your doctor or pharmacist before taking Tadalafil Stada.

Keep in mind that sexual intercourse poses a possible risk for patients with heart disease, as it puts more strain on the heart than usual. If you have heart problems, tell your doctor.

As benign prostatic hyperplasia and prostate cancer can have the same symptoms, your doctor will investigate you regarding prostate cancer before starting treatment with Tadalafil Stada for benign prostatic hyperplasia.
