General Information On Zyban
Zyban is a prescription drug used for smoking cessation. Its generic name is Bupropion, and it belongs to a class of drugs known as NDRIs (Norepinephrine and Dopamine Reuptake Inhibitors).
The active ingredient in Zyban is Bupropion Hydrochloride, and it works by blocking the reuptake of certain chemicals in the brain, which in turn reduces the craving for smoking and provides relief from withdrawal symptoms. Zyban is available in tablet form and is administered orally. Typically, doctors advise patients to buy Zyban and use it in tandem with smoking cessation counseling for quicker results.
Apart from helping people quit smoking, Zyban is also used to treat seasonal affective disorder and major depressive disorder. If you are trying to quit smoking, you can buy Zyban online after consulting your doctor.
Side effects of Zyban
Just like any medicine, Zyban has its share of side effects and it may affect different patients in different ways. However, it is not essential that all the patients using Zyban would experience its side effects. In fact, most people cope well with Zyban and do not experience any side effects at all.
Before you buy Zyban, you must inform the doctor about all your health problems, especially if you have an eating disorder like bulimia or anorexia, seizure disorder or epilepsy, a history of brain or spinal cord tumors, high blood pressure, kidney disease, bipolar disorder, liver disease, and a history of heart attacks. If you have any of these conditions, your doctor may prescribe a special dose of Zyban and ask you to undergo certain medical tests.
The most common and the minor side effects of Zyban are:
- Eating less or more than usual, sudden weight loss or weight gain
- Deprived interest in sex
- lack of proper sleep
- mild headache or dizziness
- constipation, nausea, vomiting, and dry mouth
The rare but serious side effects of Zyban are:
- severe skin rashes or blistering of the skin
- general ill feeling, joint pain, and swollen glands
- Experiencing unusual thoughts or hallucinations
If you experience any of the above mentioned side effects, you must immediately seek medical help.
Pregnant and breastfeeding women must avoid using Zyban without first consulting their doctor. Clinical studies suggest that Zyban passes into breast milk and can potentially harm a nursing baby. Therefore, breastfeeding women should not buy Zyban unless their doctor specifically advises them to use it.
Dosage of Zyban
Doctors prescribe different Zyban dosages for different patients depending on their age, other health problems they have, and the types of other medications used. The standard recommended dose is Zyban 150 mg per day and from the 4th day, the dosage is increased to two 150mg tablets per day. The treatment is continued for 7 to 10 weeks.
Make sure that you maintain a gap of at least 8 hours between each dose. You can take Zyban with or without food.
If used along with other medicines, Zyban can cause adverse drug interactions. It may potentially interact with the following:
- birth control pills
- Insulin and diabetes medicines that are taken orally
- drugs that prevent the rejection of a new transplanted organ
- asthma medicines
- antibiotics such as Ciprofloxacin and Amoxicillin

What is a "Generic" medication/drug?
Generic drugs are medications that have the 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 comparative testing to ensure that they are the same as 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 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 comparable 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 be comparable in strength and dosage to 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 comparable. They may look different, and be called something different, but they are required to be have the same active ingredient.
How are Generic drugs tested to ensure quality and efficacy?
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.
