About Hytrin

What Hytrin is used for

HYTRIN is used to treat:

  • Hypertension (high blood pressure)

  • Benign prostatic hyperplasia (enlargement of the prostate gland)

HYTRIN is for symptomatic benign prostatic hyperplasia (BPH) and not for prostate cancer. It is possible for men to have both BPH and prostate cancer at the same time. HYTRIN is not a treatment for prostate cancer.

Doctors usually recommend that men be checked for prostate cancer once a year when they turn 50 (or 40 if a family member has had prostate cancer). These checks, including Prostate Specific Antigen (PSA), should continue while you are taking HYTRIN.

What Hytrin does

HYTRIN works by relaxing blood vessels so that blood passes through them more easily. This helps to lower blood pressure.

HYTRIN also blocks smooth muscle receptors of the bladder neck and the prostate called alpha-1 adrenoceptors. This blockade causes the smooth muscles of the bladder neck and prostate to relax and decreases muscle tone. This can lead to a rapid improvement in urine flow and symptoms within a 2 week period.

When Hytrin should not be used

HYTRIN should not be used if you are allergic to any component of HYTRIN, including active ingredient and non-active ingredients.

Interactions with Hytrin

In general, you should avoid the use of phosphodiesterase (PDE5) inhibitors such as VIAGRA (sildenafil), CIALIS (tadalafil) or LEVITRA (vardenafil) when taking HYTRIN due to the risks of developing serious hypotension (low blood pressure).

Administration of HYTRIN with verapamil (i.e., ISOPTIN, TARKA or CHRONOVERA) to hypertensive patients may result in low blood pressure and/or a rapid heart beat.

Do not take these drugs with HYTRIN without your doctor’s advice.


Proper Use of Hytrin

Usual dose

Follow your doctor’s instructions very carefully about how to take HYTRIN. The starting dose is 1 mg at bedtime. The 1 mg dose should be maintained during the first week of treatment, and should be taken every day as prescribed by your doctor. Your doctor will then gradually increase the strength of your prescription to 2 mg, 5 mg, or 10 mg depending on how well you respond. The maximum recommended daily dose is 20 mg per day.

You should see an effect on your symptoms in 2 to 4 weeks. While taking HYTRIN, you should have regular check-ups to evaluate your progress regarding your BPH and to monitor your blood pressure.

Overdose

If you or someone you know accidentally takes more than stated dose, contact your doctor immediately or go to the nearest hospital with the tablets. Tell your doctor or hospital how much was taken. Treat even small overdoses seriously.

Missed dose

If you forget to take one tablet, take another as soon as you remember, unless it is almost time for your next dose. If it is, do not take the missed tablet at all.

Never double-up on a missed dose.

Talk to your doctor if you have not taken HYTRIN for a few days. You may have to restart at the 1 mg dose. Be cautious about possible dizziness.


Side Effects for Hytrin and What to Do About Them

Along with its needed effects, a medicine may cause some unwanted effects. These are referred to as “side effects”. Although not all of these side effects may occur, if they do occur they may need medical attention.

HYTRIN can cause a sudden drop in blood pressure after the very first dose. You may feel dizzy, faint, or "light-headed", particularly after you get up from bed or from a chair. This is more likely to occur after you have taken the first few doses, but can occur at any time while you are taking the drug. It can also occur if you stop taking the drug and then restart treatment.

Because of this effect, your doctor may have told you to take HYTRIN at bedtime. If you take HYTRIN at bedtime but need to get up from bed to go to the bathroom, get up slowly and cautiously until you are sure how the medicine affects you. It is also important to get up slowly from a chair or bed at anytime until you learn how you react to HYTRIN.

Other side effects with HYTRIN include back pain, constipation, diarrhea, drowsiness or sleepiness, dry mouth, flatulence, headache, impotence, indigestion, libido decreased, nasal congestion, nausea, “puffiness” of the feet or hands, swelling, urinary frequency, urinary incontinence primarily reported in postmenopausal women, urinary tract infection, weakness or weight gain.

Discontinue your medication and inform your physician if you experience any of the following: anxiety, difficulty breathing/shortness of breath, heart palpitations, rash, drowsiness/sleepiness sweating, vomiting, blurred or hazy vision, weakness, allergic reaction, chest pain, decreased blood pressure or low blood pressure, permanent erection, unknown bruising or increased bleeding after a cut.

Check with your physician or pharmacist if you experience any unexpected effects, or are concerned by the above side effects.
