What is a Generic Drug?

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.

    Directions

    Take the medication as prescribed by your doctor. You should finish your treatment course, even if you start to feel better. If you have questions or concerns, talk to your doctor or pharmacist.

    Each patient's dose depends on age and the type of infection being treated. The duration of treatment is usually 7 to 14 days, but it depends on the type of infection being treated and its severity. The dose may need to be adjusted in patients with kidney problems. 

    Ingredients

    Cephalexin, a cephalosporin, is the active ingredient in Keflex.

    Contraindications

    Patients who are allergic to Keflex or any of the other antibiotics in its class should not take the medication.

    Cautions

    • Before you begin treatment with Keflex, you should tell your doctor about:
      • All the medications you take
      • Your allergies
      • Your health history and current health problems
      • Your pregnancy or breastfeeding status
    • Keflex can cause serious allergic reactions, including anaphylaxis. You should seek emergency care immediately if you have trouble breathing, a rash, or swelling of the face, tongue, or throat. 
    • Keflex can cause Clostridium difficile-associated diarrhea.
    • Anemia can occur during treatment with cephalosporins.
    • Seizures can occur with cephalosporins, especially in patients with kidney problems. 
    • Cephalosporins can cause prolonged prothrombin time, especially in patients with kidney or liver problems, malnutrition, or in patients receiving a protracted course of antibiotics and in patients taking anticoagulants.
    • Long-term use of Keflex can cause an overgrowth of bacteria that has become resistant to the antibiotic.

    Side Effects

    Keflex can cause side effects, including diarrhea, nausea, vomiting, indigestion, and stomach pain. However, other side effects can occur, and it's recommended that you call your doctor if you develop side effects that bother you or won't go away.
