1. What Hytrin Tablets are and what they are used for

The name of your medicine is Hytrin 1 mg, 2 mg, 5 mg, or 10mg Tablets (called Hytrin Tablets in this leaflet). Hytrin Tablets contains the active ingredient terazosin. Terazosin belongs to a group of medicines called alpha-blockers. Hytrin Tablets are used in adults to treat high blood pressure. Hytrin Tablets are also used in adults for the treatment of a condition called benign prostatic hyperplasia (BPH) which affects the prostate and is common in older men. This condition stops the flow of urine from the bladder and can lead to symptoms such as a weak or interrupted urine flow, a need to pass water more frequently and/or a sudden need to pass water. Hytrin Tablets can relax the muscle of the prostate gland and bladder exit to help relieve these symptoms.

2. What you need to know before you take Hytrin Tablets
Do not take Hytrin Tablets
  • if you are allergic to terazosin or any of the other ingredients of this medicine listed in section 6 (allergic reactions include mild symptoms such as itching and/or rash. More severe symptoms include swelling of the face, lips, tongue and/or throat with difficulty in swallowing or breathing).
  • if you are allergic to any of the following drugs: alfuzosin, indoramin, prazosin, tamsulosin, doxazosin.
  • if you have ever fallen over or fainted while passing water.

Warnings and precautions

Talk to your doctor or pharmacist before taking Hytrin Tablets if you:

  • are taking other medication for high blood pressure. If a medicine for high blood pressure is started whilst you are taking Hytrin Tablets, then your doctor may need to adjust your dose of Hytrin Tablets.
  • have any problems with your heart.
  • are taking medicines for erectile dysfunction (e.g. Cialis, Viagra, Levitra).
  • are planning cataract removal surgery.

Hytrin Tablets must be used for BPH only after excluding other possible reasons in urinary tract for abnormal/ interrupted urinary flow.

Hytrin Tablets can cause fainting or low blood pressure, usually after the first or first few doses. These effects can also occur if you stop taking Hytrin Tablets and then re-start.

Hytrin Tablets may also lead to decreases of certain laboratory values, such as red blood cells or white blood cells.

If any of the above applies to you, or if you are not sure, please tell your doctor before taking Hytrin Tablets.

Children and adolescents

Hytrin Tablets are not recommended for use in children.

Other medicines and Hytrin Tablets

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

It is especially important to tell your doctor if you are taking;

  • other medicines to treat high blood pressure including ACE inhibitors and water tablets (diuretics);
  • medicines for erectile dysfunction (e.g. Cialis, Viagra, Levitra, Stendra).

Some patients who take alpha-blocker therapy for the treatment of high blood pressure or prostate enlargement may experience dizziness or light-headedness which may be caused by low blood pressure upon sitting or standing up quickly.

The medicines which cause low blood pressure with alpha blockers include

  • Medicines treating high blood pressure - adrenergic neurone blockers (e.g. Guanithidine),
  • alcohol,
  • cancer treating medicine (e.g. aldesleukin),
  • medicines for treating high blood pressure (e.g. Angiotensin – II receptor antagonists, Beta blockers, Calcium-channel blockers, Clonidine, Moxinidine, Tizanidine Diazoxide, Hydralazine, Nitrtaes, Sodium nitroprusside
  • medicines for treating schizophrenia (antipsychotics),
  • medicines for treating muscle spasm (e.g. baclofen),
  • anti-inflammatory drugs like corticosteroids,
  • medicines used for general anesthesia before surgery.
  • medicine used for baldness (Minoxidil)
  • medicines for treating Parkinson’s condition (e.g. levodopa and Methyldopa)
  • medicines for treating depression (MAOI’s)
  • medicines for chest pain (nitrates)
  • pain killers
  • female sex hormone (estrogen)

Certain patients have experienced these symptoms when taking drugs for erectile dysfunction (impotence) with alpha-blockers. These medicines include alprostadil and Moxisylyte. In order to reduce the likelihood that these symptoms occur, you should be on a regular daily dose of your alpha-blockers before you start drugs for erectile dysfunction.

If you are going to have a general anaesthetic, you should tell the doctor or dentist in charge that you are taking Hytrin Tablets.

If you are undergoing eye surgery because of cataract (cloudiness of the lens) please inform your eye specialist before the operation that you are using or have previously used Hytrin Tablets. This is because Hytrin Tablets may cause complications during the surgery which can be managed if your specialist is prepared in advance.
