In this article, we will explore everything you need to know about Keflex generic, including its composition, uses, benefits, potential side effects, and considerations for use.
Understanding Keflex and Its Generic Version
What Is Keflex?
Keflex is a brand name for an antibiotic whose active ingredient is cephalexin. Cephalexin belongs to the cephalosporin class of antibiotics, which are structurally and functionally similar to penicillins. It works by inhibiting bacterial cell wall synthesis, leading to bacterial cell death.
What Is a Keflex Generic?
A generic medication contains the same active ingredients as the brand-name drug but is usually sold at a lower price. The Keflex generic is typically cephalexin in its standard form, manufactured by various pharmaceutical companies according to strict regulatory standards.
Differences Between Brand-Name Keflex and Its Generic Version
The primary differences are:
- Inactive Ingredients: Generics may have different fillers, binders, or dyes, which generally do not affect efficacy but can influence tolerability in some individuals.
- Price: Generics tend to be more affordable due to lower manufacturing costs and market competition.
- Appearance: The pills might differ in color, shape, or size but contain the same active compound.
Uses and Indications of Keflex (Cephalexin)
Keflex generic is prescribed for various bacterial infections, particularly those caused by susceptible strains. Common indications include:
