1. What Doxazosin Stada is and what it is used for

Your doctor may have prescribed Doxazosin Stada for high blood pressure, which may increase the risk of heart disease and stroke if left untreated. The active substance in the tablet, doxazosin, belongs to a group of medicines called alpha-1 antagonists. These drugs work by dilating the blood vessels, making it easier for the heart to pump blood through them. This helps to lower blood pressure and reduce the risk of heart disease.

Your doctor may also have prescribed Doxazosin Stada to treat the symptoms of benign prostatic hyperplasia. This condition means that the prostate, which is located just below the bladder in men, is enlarged. This makes it more difficult to empty the bladder. Doxazosin Stada works by relaxing muscles around the bladder outlet and the prostate gland, making it easier to empty the bladder.

Doxazosin contained in Doxazosin Stada may also be approved for the treatment of 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.

2. What you need to know before using Doxazosin Stada

Do not use Doxazosin Stada

  • if you are allergic to doxazosin, quinolones (eg prazosin, terazosin) which are the chemical family of medicines to which doxazosin belongs, or any of the other ingredients of this medicine (listed in section 6)
  • if you have low blood pressure ( hypotension ) or if you have a drop in blood pressure when you get up that has caused dizziness, fainting, or fainting ( orthostatic hypotension )
  • if you have benign prostate enlargement and at the same time a narrowing of the upper urinary tract, chronic urinary tract infection, or stones in the bladder
  • if you have or have had any kind of narrowing of the gastrointestinal tract
  • if you have overflow incontinence (loss of bladder control), anuria (no urinary excretion), or progressive deterioration of kidney function
  • if you are breast-feeding.

Warnings and cautions

Talk to your doctor or pharmacist before taking Doxazosin Stada.

  • if you have any liver disease
  • if you have had an acute heart disease such as heart failure
  • if you are under 18 years of age
  • if you are taking Doxazosin Stada and so-called phosphodiesterase -5 inhibitors (eg sildenafil, tadalafil, or vardenafil), both of which have an antihypertensive effect (see section 2 “Other medicines and Doxazosin Stada”)
  • dizziness, weakness, and in rare cases fainting may occur, especially at the beginning of treatment. You should therefore be especially careful at the beginning of treatment and avoid situations that could lead to injury should these symptoms occur.

Your doctor will tell you what to do if you experience postural hypotensive symptoms (a decrease in blood pressure and symptoms when you change your posture, for example from lying or sitting to a standing position).

You should not worry if you sometimes discover a tablet-like part of your stool. Doxazosin Stada has a tablet casing that is not absorbed in the gastrointestinal tract, this is designed to control the release from the tablet over a delayed time.

If you are going to have eye surgery due to cataracts (turbidity of the lens of the eye), you must inform your eye specialist before the operation that you are using or have used Doxazosin Stada. This is because the use of Doxazosin Stada can cause complications during the surgery which can be managed if your specialist is informed.

Children and young people

Doxazosin Stada is not recommended for use in children or adolescents below 18 years of age as safety and efficacy have not yet been established.

Other medicines and Doxazosin Stada

  • Other medicines for high blood pressure

Some patients who use alpha-receptor blockers such as Doxazosin Stada for the treatment of high blood pressure or prostate enlargement can experience dizziness or fainting, which can be caused by low blood pressure when you quickly sit or stand up. Some patients have experienced these symptoms after using impotence ( erectile dysfunction ) medicines with alpha-receptor blockers. To reduce the risk of these symptoms, you should use alpha-receptor blockers regularly with a fixed daily dose before you start using impotence medicines.
