General Information on Hytrin
Doctors advise men suffering from benign prostatic hyperplasia or patients of high blood pressure to buy Hytrin for treating their condition. The main chemical ingredient of Hytrin is Terazosin, which works by itself or in combination with other drugs to treat high blood pressure. Terazosin is classified as an alpha-adrenergic blocking drug. This drug works by relaxing the veins and arteries, enabling blood to pass through them easily. Instead of shrinking the prostate, it relaxes the muscles at the neck of the bladder and prostate, which makes it easy for urine to flow through and empty the bladder. As an added advantage, it also reduces excessive night urination problems.
Hytrin Side Effects
An allergy to Terazosin is the biggest risk of using Hytrin. Any signs of allergic reactions such as hives, breathing difficulties, and swelling of the face, tongue, throat, and lips should be reported to your doctor at once. Some other serious side effects include fast heartbeat, fainting, swelling of the hands and feet, and a painful erection. Less serious reactions include weakness, headache, numbness, stuffy nose, or blurred vision.
Those allergic to Terazosin should not use this medication. Hytrin can cause dizziness and fainting immediately after you start or stop the medication. Driving and similar activities, which require alertness, should be avoided during those times when the medicine is started or stopped. Also, standing up for a long time, becoming overheated while working out, being out in hot weather, and getting up too fast from a sitting or lying position should be avoided.
Hytrin needs regular dosage adjustments. If you start the medication after a long interval or have continued the same dose for more than two months, get a checkup done. Since Hytrin affects the pupils during cataract surgery, let your eye surgeon know if you are on this medication.
Those with a history of prostate cancer need to inform the doctor before taking this drug. Also, pregnant ladies should have this drug in controlled doses and under the doctor’s supervision only.
Hytrin should be taken in the exact dosage as prescribed by the doctor and for the exact time that the doctor recommends it. The initial dosage usually starts with Hytrin 1mg at bedtime and is then increased to Hytrin 2mg. Once the desired results begin to show, the dosage is increased to Hytrin 5mg and Hytrin 10mg to ensure that steady improvement ensues. The patients are continually monitored so that the risks of severe hypotension are minimized.
Missed doses should be taken as soon as remembered unless it is time for the next dose. Never take extra medicine to make up for missed doses, as it can be fatal.
There are a number of medications which interact with Hytrin. Sildenafil medications such as Viagra and Revatio interact with the medicine. Tadalafil, Vardenafil, Verapamil, and diuretics also interact severely with Hytrin. Antihistamines, muscle relaxants and pain relievers should also be used only after you consult your doctor. Before starting any new medication while using Hytrin, be sure to consult your doctor as you may suffer from severe reactions due to medicine interactions.
Terazosin is a prescription-only drug, and you should not buy Hytrin unless your doctor has prescribed it.

What is a "Generic" medication/drug?
Generic drugs are medications that have comparable medicinal ingredients as the original brand name drug, but which are generally cheaper in price. Nearly 1 in 3 drugs dispensed are "generic". They undergo testing to ensure that they are similar to their "brand" counterparts in:
- Active Ingredient (e.g. "Pravastatin" is the active ingredient in brand name Pravachol)
- Dosage (e.g. 10 mg of the active ingredient)
- Safety (e.g. same or similar side effects, drug interactions)
- Performance (e.g. 10 mg of a "generic" can be substituted for 10 mg of the "brand" and have the same therapeutic result)
- Intended use (e.g. both "generic" and "brand" would be prescribed for the same conditions)
What this means is that "generic" medications can be used as a substitute of their brand equivalents with the comparable therapeutic results. There are a few exceptions (examples are outlined at the end of this page) and as always you should consult your physician before switching from a brand name medications to a generic or vice versa.
What differences are there between generic and brand?
While generics and brand equivalent drugs contain the same active ingredients, they may be different in the following ways:
- Appearance (e.g. the scoring or markings)
The color, shape and size of the medication come from the fillers that are added to the active ingredients to make the drug. These fillers that are added to the drug have no medical use and do not to change the effectiveness of the final product. A generic drug must contain comparable active ingredients and must have a comparable strength and dosage as the original brand name equivalent. Generic drugs can be more cost effective than purchasing the brand name.
Why do generics cost less than the brand name equivalents?
When a new drug is "invented", the company that discovered it has a patent on it that gives them the exclusive production rights for this medication. Once the patent expires in a country, other companies can bring the product to market under their own name. This patent prevents other companies from copying the drug during that time so they can earn back their Research and Development costs through being the exclusive supplier of the product. After the patent expires however, other companies can develop a "generic" version of the product. These versions generally are offered at much lower prices because the companies do not have the same development costs as the original company who developed the medication.
The main thing to realize here though is that the two products are therapeutically equivalent. They may look different, and be called something different.
How are Generic drugs tested to ensure quality and efficacy?
Generally speaking, the two most generally accepted methods to prove the safety of a generic version of a drug are to either repeat most of the chemistry, animal and human studies originally done, or to show that the drug performs comparably with the original brand name drug. This second option is called a "comparative bioavailability" study. During this type of study, volunteers are given the original drug, and then separately later the generic drug. The rates at which the drug is delivered to the patient (into their blood stream or otherwise absorbed) are measured to ensure they are the same. Because the same active ingredient is used the major concern is just that it delivers the common chemical(s) at the same rate so that they have the same effect. Please note that the methods that the manufacturers use may vary from country to country.
