General Information On Viagra
Viagra is used to treat male impotence (erectile dysfunction). The generic name of the drug is Sildenafil Citrate. It is available in the form of tablets that need to be taken orally. Erectile Dysfunction (ED) takes place when adequate blood is not supplied to the penis, which either prevents an erection or makes it short-lived. Viagra works to boost the flow of blood to the penis, thus enabling an erection or sustaining it. Though the drug may help improve your sex life, you should buy Viagra only after proper consultation with your doctor.
Side Effects for Viagra
Viagra may cause side effects in some people even when the drug is taken as recommended. You may experience numbness, dizziness, nausea, or tingling in your arms, chest, jaw, or neck. You should immediately call you doctor if you experience any side effects after taking Viagra. Some people may also experience serious side effects such as sudden hearing or vision loss, swelling of the feet, ankles, or hand, vision changes, irregular heartbeat, cheat pain, sweating, or a general ill feeling. If you experience any severe side effects, you should immediately stop taking Viagra and consult your doctor. The medication is known to work for almost 4 hours, but if your erection stays for 4 hours or longer, then you must contact your doctor immediately.
You should not take Viagra if you are already taking any nitrate drug for heart problems or chest pain, as a combination of both drugs can lead to a serious and sudden decrease in blood pressure. Viagra should not be taken by people with certain medical conditions. You should inform your doctor if you have any heart rhythm problems or heart disease, high or low blood pressure, kidney or liver disease, coronary heart disease, and blood cell disorders such as leukemia, sickle cell anemia, or multiple myeloma. Consult your doctor if you have history of heart attack, congestive heart failure, or you have a bleeding disorder such as hemophilia. Viagra may not be the ideal drug for men with retinitis pigmentosa or Peyronie's disease. Since it can cause side effects, you should buy Viagra only after getting the prescription from your doctor.
Viagra should be taken only as recommended by your doctor. The drug is available in the tablet form in three strengths; Viagra 25mg, Viagra 50 mg, and Viagra 100mg. The medication should be taken 30 minutes or 1 hour prior to any sexual activity. You should not take the medication more than once a day. The dose needs to be taken as required (before sexual activity) and as such, there are no recommended timings for taking the drug.
Viagra may react with other drugs and cause side effects. You should not take Viagra with similar medications such as Vardenafil (Levitra) or Tadalafil (Cialis). It can also interact with medications such as Bosentan (Tracleer), Conivaptan (Vaprisol), Isoniazid, and Imatinib (Gleevec). Viagra can have adverse reactions with some antibiotics, antidepressants, and antifungal medications.

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.
