  • What is Ceftin?

    Ceftin is a cephalosporin antibiotic used to treat mild to moderate bacterial infections. Ceftin tablets are used to treat infections of the ear, respiratory tract, sinuses, skin, throat, tonsils, and urinary tract. Ceftin tablets are also used to treat gonorrhea (a sexually transmitted disease characterized by itching and burning during urination) and early-stage Lyme disease. Ceftin oral suspension is used to treat infections of the ear, throat, tonsils, and skin in children 3 months to 12 years of age.

  • What is the most important information I should know about Ceftin?

    Ceftin works only against bacteria. It will not cure an infection caused by a virus, such as the common cold or flu.

    Ceftin tablets and Ceftin oral suspension are not equivalent to each other; do not substitute one for the other.

    If you are allergic to either penicillin or cephalosporin antibiotics, such as cefaclor, cefprozil, or cephalexin, consult your doctor before taking Ceftin. There is a possibility that you are allergic to both types of medication. If a reaction occurs, it could be extremely severe. If you take Ceftin and develop shortness of breath, a pounding heartbeat, a skin rash, or hives, seek medical attention immediately.

    Long-term or repeated use of Ceftin may cause a secondary infection. Tell your doctor if signs of a secondary infection occur. Your medicine may need to be changed to treat this.

    Mild diarrhea is common with antibiotic use. However, a more serious form of diarrhea, although rare, may occur. Contact your doctor right away if you experience stomach pain or cramps, severe diarrhea, or bloody stools. Do not treat the diarrhea without first checking with your doctor.

    Ceftin oral suspension contains phenylalanine. Notify your doctor if you have a condition called phenylketonuria (an inability to process phenylalanine).

  • Who should not take Ceftin?

    Do not take Ceftin if you are allergic to it, to any other cephalosporin antibiotics, or to penicillin.

  • What should I tell my doctor before I take the first dose of Ceftin?

    Tell your doctor about all prescription, over-the-counter, and herbal medications you are taking before beginning treatment with Ceftin. Also, talk to your doctor about your complete medical history, especially if you are taking blood-thinning medications (such a warfarin), have a condition called phenylketonuria, a history of inflammation of the large intestine (colitis), kidney disease, or liver disease.

Not completing the full dosage schedule may decrease the drug's effectiveness and increase the chances that the bacteria may become resistant to Ceftin and similar antibiotics. If this happens, Ceftin and similar antibiotics may not work in the future.

  • What should I avoid while taking Ceftin?

    Take Ceftin only when it is prescribed by your doctor, even if you have symptoms that are similar to those of a previous infection. Continued or prolonged use of Ceftin can lead to new infections that do not respond to Ceftin.
