What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

Description

Hytrin is an alpha-1 selective adrenoceptor blocking agent commonly used to treat benign prostatic hyperplasia (BPH) and high blood pressure. Terazosin works by relaxing blood vessels and muscle fibers in the prostate and bladder neck, making it easier to urinate. It also helps widen blood vessels to improve blood flow and reduce blood pressure. It is typically prescribed to adult men experiencing urinary difficulties due to an enlarged prostate gland or to patients needing hypertension management.

Directions

When starting Hytrin for BPH or high blood pressure, start with a 1 mg dose at bedtime, not exceeding this initial dose to reduce the risk of severe low blood pressure (hypotension). If needed, the dose can be gradually increased stepwise up to 10 mg once daily for symptom improvement, with some patients requiring up to 20 mg. Blood pressure and symptoms should be monitored closely, especially when used with other antihypertensive agents or PDE-5 inhibitors. If treatment is paused for several days, restart at the initial 1 mg dose.

Ingredients

The active ingredient in Hytrin is terazosin.

Contraindications

Avoid taking or using this medication if you have a known hypersensitivity to terazosin or other quinazolines.

Cautions

  • Before taking Hytrin, you may want to consult a healthcare provider about the following:
    • Any existing health conditions
    • Any allergies
    • A list of all medications you are currently taking
    • Whether you are pregnant or breastfeeding
  • Hytrin can cause a sudden drop in blood pressure, especially when starting the medication or after a break in treatment. This effect usually happens within a few hours after taking the first dose or when the dose is increased. To reduce this risk, the first dose should always be taken at bedtime, and any increases should be done slowly.
  • Because Hytrin may cause dizziness or fainting, especially early in treatment, avoid driving or doing activities where sudden fainting could cause harm. Get up slowly from sitting or lying down to help prevent lightheadedness.
  • In rare cases, Hytrin has been linked to priapism, a painful and long-lasting erection not caused by sexual activity. This is a medical emergency—if it happens, seek help right away to avoid permanent damage.
  • People taking or who have taken Hytrin may experience Intraoperative Floppy Iris Syndrome (IFIS) during cataract surgery, which can make the procedure more complicated. Tell your eye surgeon if you are currently using or have ever used Hytrin.
  • Hytrin treats symptoms of an enlarged prostate, but it does not prevent or treat prostate cancer. Because both conditions can have similar symptoms, your doctor should check for cancer before starting Hytrin.
  • Hytrin is not recommended during pregnancy unless the benefits outweigh the risks. It's not known if Hytrin passes into breast milk, so talk to your doctor before using it while nursing.
  • The safety and effectiveness of Hytrin in children have not been established.

Side Effects

The most common side effects of Hytrin include dizziness, fatigue, drowsiness, nasal congestion, and low blood pressure when standing. Some men may also experience impotence or reduced libido. These reactions are usually mild to moderate and are more likely to occur during the first week of treatment or after dose increases. In rare cases, more serious reactions like fainting, blurry vision, or urinary incontinence may occur.

Other possible side effects include nausea, swelling in the limbs, headache, and respiratory issues like nasal or sinus congestion. Less common reactions such as chest pain, dry mouth, rash, and abnormal vision have also been reported. Rare but serious effects include allergic reactions, priapism, and intraoperative floppy iris syndrome during eye surgery. Talk to your doctor if you experience troubling side effects or symptoms that worsen over time.
