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.
Betaxolol is used for the treatment of glaucoma.
Both hands should be washed before each use of betaxolol or any other eye medication. The head should be tilted back and the lower lid pulled down with the index finger to form a pouch. The tip of the squeeze bottle should not be touched to the eye or eyelid. The bottle should be squeezed slightly to allow the prescribed number of drops into the pouch. The eye is closed gently for 1 to 2 minutes without blinking. The usual dose is 1 to 2 drops into each affected eye twice daily.
Ophthalmic betaxolol can cause side effects which are usually mild and transient. The most common side effect is transient ocular (temporary eye) discomfort. Rarely, betaxolol eye drops can result in side effects that are seen with oral beta-adrenergic blockers. For example, persons can experience fatigue, insomnia, nausea, dizziness, lightheadedness, depression, slow heart rate, low blood pressure, cold extremities, and shortness of breath or wheezing.
