Tadalafil 20mg

Penis deformation: As with other medications for erectile dysfunction, men with an anatomical deformation of the penis such as angulation, cavernosal fibrosis, or Peyronie's disease should be closely monitored by their doctors if they take this medication. If you have any of these conditions, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Prolonged erection (priapism): If an erection lasts longer than 4 hours (a rare occurrence), seek immediate medical assistance. If this condition is not treated quickly, tissue damage and permanent loss of the ability to have an erection could result.

Tell your doctor if you have any of the following conditions, as they may increase your risk of a prolonged erection: sickle cell anemia, multiple myeloma, or leukemia.

Prostate problems: If you are taking other medications tadalafil 20mg to treat BPH called alpha blockers (e.g., doxazosin), let your doctor know. The combination of alpha blockers with tadalafil is not recommended for treatment of BPH. People who are taking tadalafil for erectile dysfunction may be able to continue taking alpha blockers. Talk to your doctor for more information.

Vision problems: If you experience a sudden loss of vision in one or both eyes, or other vision-related problems, contact your doctor immediately. Vision loss may be partial or complete. While in some cases the condition may improve over time, it can be permanent in other cases. This is a rare condition that more likely to occur if you have heart disease, high blood pressure, high cholesterol, diabetes, or eye problems, if you are more than 50 years old, or if you smoke.

Pregnancy and breast-feeding: Tadalafil is not intended for use by women.

Children and adolescents: Tadalafil is not intended for use by children or adolescents under 18 years old.

  2. change one of the medications to another,
  3. change how you are taking one or both of the medications, or
    leave everything as is.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications that you are taking. Also tell them about any supplements you take.
