Omnicef is a brand name for cefdinir, an antibiotic.
How It Works
Cefdinir, the active ingredient in Omnicef, is known as a cephalosporin antibiotic. Cefdinir can kill bacteria by weakening cell walls. Cefdinir disrupts the process where bacteria can build a strong cell wall. Weak cell walls quickly crumble and the bacteria die, thus clearing the infection in the body.
Omnicef is a commonly prescribed antibiotic to treat bacterial infections in the ears, sinuses, throat, tonsils and skin. It’s usually prescribed to treat tonsillitis, bacterial pneumonia, bacterial sinusitis and bronchitis.
Omnicef is not effective for treating cold, flu or other conditions caused by viruses. Do not use antibiotics when there is no bacterial infection present to reduce the risk of getting a drug-resistant bacterial infection later.
Omnicef is available in capsule and liquid form.
Your doctor will prescribe you the correct dose of Omnicef to take depending on the strain of bacteria affecting you, the severity of the condition, body weight, age and medical history.
Follow the dosage instructions exactly as prescribed by your doctor. Do not take higher or lower doses unless your doctor tells you to. Stick to the dosage schedule your doctor recommends for the treatment to be effective.
Omnicef should be taken once or twice a day between 12 or 14 hour intervals. Take Omnicef the same time each day to keep an even dose in your body at all times to fight off the infection.
You may be required to take Omnicef for 5 to 10 days. Do not abruptly stop treatment early as the infection may return full force.
Read the instructions provided with the packaging before use.
When taking Omnicef pills, swallow them whole, without crushing or breaking. When taking the oral suspension liquid, measure your dose accurately using a medicine measuring device. Shake the suspension bottle well before using.
You may experience one or more of the following side effects when taking Omnicef:
Some side effects may be severe than others. Tell your doctor about side effects that do not disappear over time, or gets unbearably worse.
Do not take Omnicef if you are allergic to cefdinir or any other type of cephalosporin antibiotic. Make sure you are not allergic to any of the inactive ingredients in the capsules or suspension liquid either.
Omnicef may cause dangerous reactions with other types of medication such as probenecid. Inform your doctor about all types of prescription and nonprescription medications, vitamins, dietary supplements and herbal products you are currently taking.
Antacids, multivitamins and foods containing magnesium, aluminum and iron may hinder the absorption of Omnicef by the body. It’s advised to take Omnicef 2 hours before or after consuming such foods or vitamins.
As your doctor if Omnicef is safe for you if you have a history of gastrointestinal disease, colitis or kidney disease.
If Omnicef causes diarrhea, it’s important to drink a lot of liquids to stay hydrated.
Do not skip doses of Omnicef. Continue your treatment even if you feel better.
If you do skip a dose, take it as soon as you remember, but before it’s too close to the time for the next dose. Do not take double doses of Omnicef at once.
