Cefdinir vs. cefixime (Suprax) quick comparison of the differences
- Cefdinir and cefixime (Suprax) are 3rd generation cephalosporin antibiotics used to treat a wide range of infections, for example:
- Cefdinir and cefixime have similar side effects that include:
- Side effects of cefdinir that are different from cefixime include vaginal yeast infection.
- Rare side effects of cefdinir include:
- Side effects of cefixime that are different from cefdinir include:
- Both cefdinir and cefixime may cause a potentially serious condition called pseudomembranous colitis (Clostridium difficile colitis, C. diff), a bacterial infection of the colon.
- If you are allergic to penicillin-type antibiotics, you also may be allergic to cefdinir or cefixime.
- Rare, but serious allergic reactions to cefdinir and cefixime include:
What are cefdinir and cefixime? What type of antibiotics are they?
Cefdinir and cefixime (Suprax) are partially man made (semi-synthetic) 3rd generation antibiotics that belong to the drug class called cephalosporins. Bacteria cannot survive without a cell wall, so cephalosporins prevent the bacteria from multiplying, which then prevents bacteria from forming the walls that surround them.
What infections do cefdinir vs. cefixime treat (uses)?
Cefdinir and cefixime both are used for the treatment of a wide variety of bacterial infections , for example, infections of the:
- Middle ear (otitis media)
- Tonsils (tonsillitis)
- Throat (strep throat)
- Larynx (laryngitis)
- Sinuses (sinusitis)
- Bronchi (bronchitis)
- Lungs (pneumonia)
- Skin and other soft tissues
Cefdinir additional uses
Cefdinir also is used for the treatment of:
- Urinary tract infections
- Acute bacterial bronchitis in patients with chronic obstructive pulmonary disease (COPD)
Cefdinir is not active against pseudomonas.
What are the differences in the side effects of cefdinir vs. cefixime?
Cefdinir side effects
Cefdinir generally is well tolerated. The most common side effects are:
Rare side effects include:
Cefdinir may cause false test results with some tests for sugar in the urine.
Like most antibiotics, cefdinir may cause a condition called pseudomembranous colitis (Clostridium difficile colitis or C. diff), a potentially serious bacterial infection of the colon. Patients who develop signs of pseudomembranous colitis after starting cefdinir (diarrhea, fever, abdominal pain, and possibly shock) should contact their doctor immediately.
Persons who are allergic to the penicillin class of antibiotics, for example, amoxicillin, amoxicillin and clavulanic acid (Augmentin), which are related to cephalosporins, may or may not be allergic to cephalosporins.
Cefixime side effects
Common side effects of cefixime include:
- abdominal pain,
- vomiting and,
- skin rash.
Other side effects include:
What is the dosage for cefdinir vs. cefixime?
- Cefdinir is taken once or twice daily, depending on the type and severity of the infection.
- The capsules or suspension can be taken with or without food.
- Patients with advanced kidney disease may need to take lower doses to prevent accumulation of cefdinir since it is eliminated from the body by the kidneys.
- For adult infections the usual dose is 300 mg every 12 hours or 600 mg per day for 5-10 days depending on the nature and severity of the infection.
- The recommended dose for children 6 months to 12 years of age is 7 mg/kg every 12 hours or 14 mg/kg per day for 5-10 days depending on the type of infection.
- For most infections, once daily dosing is as effective as twice daily dosing, although once daily dosing has not been evaluated for the treatment of skin infections or pneumonia.
- The recommended adult dose for middle ear infections, tonsillitis, sore throat, strep throat, and urinary tract infections is 400 mg once daily or divided and given as 200 mg every 12 hours.
- Pediatric patients (6 months and older) have a recommended dose of 8 mg/kg/day once daily or in two doses of 4/mg/kg every 12 hours.
What drugs or supplements interact with cefdinir vs. cefixime?
Cefdinir drug and supplement interactions
- Aluminum or magnesium containing antacids reduce the absorption of cefdinir from the intestine. Separating the administration of cefdinir and such antacids by two hours prevents this interaction.
- Iron supplements also reduce the absorption of cefdinir. Separating the administration of cefdinir and iron supplements by two hours prevents this interaction. There have been reports of reddish stool in patients who have received cefdinir. This could be due to the formation of a chemical complex between cefdinir and iron in the stomach.
Cefixime drug and supplement interactions
- Probenecid (Benemid) may increase the blood concentration of cefixime by decreasing removal of cefixime by the kidney. This interaction sometimes is used to enhance the effect of cephalosporins.
- Combining cefixime with aminoglycosides (for example, tobramycin [TobraDex] produces additive bacterial killing effects but also may increase the risk of harmful effects to the kidney.)
- Exenatide (Byetta) may delay or reduce the absorption of cephalosporins. Cephalosporins should be administered one hour before exenatide.
- Cefixime may cause a false positive urine ketone test.
Are cefdinir or cefixime safe to take during pregnancy or while breastfeeding?
- There are no adequate studies of cefdinir in pregnant women; however, studies in animals suggest no important effects on the fetus.
- Cefdinir is not secreted in human milk.

Inner Ear Infection (Symptoms, Signs, Treatments, Home Remedies)
An inner ear infection or otitis interna is caused by viruses or bacteria and can occur in both adults and children. An inner ear infection can cause symptoms and signs, for example, a severe ear, dizziness, vertigo, nausea and vomiting, and vertigo. An inner ear infection also may cause inflammation of the inner ear or labyrinthitis. Inner ear infections are not contagious; however, the bacteria and viruses that cause the infection can be transmitted to other people. Good hygiene practices will help decrease the chances of the infection spreading to others. Inner ear infection symptoms and signs like ear pain and nausea may be relieved with home remedies or over the counter (OTC) medication. Some inner ear infections will need to be treated and cured with antibiotics or prescription pain or antinausea medication.
Sore Throat Home Remedies
Natural and home remedies for sore throat symptoms and pain relief include essential oils, licorice gargles, slippery elm leaves, raw garlic, Throat Coat tea, sage, and acupuncture. Typical symptoms of a sore throat include throat pain, coughing, sneezing, fever, and swollen lymph nodes. Sore throats are caused by viral (common cold, flu, mumps), bacterial (tonsillitis, some STDs), toxins, allergens, trauma or injury, or "mechanical causes" (breathing through the mouth).
STDs in Men
Sexually transmitted diseases (STDs) are infections transmitted during sexual contact. They may be caused by viruses, bacteria, or parasites. STDs in men cause no symptoms or symptoms like genital burning, itching, sores, rashes, or discharge. Common infections that are sexually transmitted in men include gonorrhea, chlamydia, syphilis, hepatitis C and B, genital warts, human papillomavirus (HPV), and genital herpes. Some STDs in men are treatable while others are not. STDs are diagnosed with tests that identify proteins or genetic material of the organisms causing the infection. The prognosis of an STD depends on whether the infection is treatable or not. Use of latex condoms can help reduce the risk of contracting an STD but it does not eliminate the risk entirely.
Pneumonia (Symptoms, Causes, Types, Treatment, and Recovery)
Pneumonia is inflammation of the lungs caused by fungi, bacteria, or viruses. Symptoms and signs include cough, fever, shortness of breath, and chills. Antibiotics treat pneumonia, and the choice of the antibiotic depends upon the cause of the infection.
Middle Ear Infection (Otitis Media)
Middle ear infection (otitis media) is inflammation of the middle ear. There are two forms of this type of ear infection, acute and chronic. Acute otitis media is generally short in duration, and chronic otitis media generally lasts several weeks. Babies, toddlers, and children with a middle ear infection may be irritable, pull and tug at their ears, and experience numerous other symptoms and signs. Treatment depends upon the type of ear infection.
Urinary Tract Infection (UTI)
A urinary tract infection (UTI) is an infection of the bladder, kidneys, ureters, or urethra. E. coli, a type of bacteria that lives in the bowel and near the anus, causes most UTIs. UTI symptoms include pain, abdominal pain, mild fever, urinary urgency and frequency. Treatment involves a course of antibiotics.
Tonsillitis is a contagious infection with symptoms of bad breath, snoring, congestion, headache, hoarseness, laryngitis, and coughing up blood. Tonsillitis can be caused acute infection of the tonsils, and several types of bacteria or viruses (for example, strep throat or mononucleosis). There are two types of tonsillitis, acute and chronic. Acute tonsillitis lasts from one to two weeks while chronic tonsillitis can last from months to years. Treatment of tonsillitis and adenoids include antibiotics, over-the-counter medications, and home remedies to relieve pain and inflammation, for example, salt water gargle, slippery elm throat lozenges, sipping warm beverages and eating frozen foods (ice cream, popsicles), serrapeptase, papain, and andrographism Some people with chronic tonsillitis may need surgery (tonsillectomy or adenoidectomy).
Ear Infection Home Treatment
Infections of the outer, middle, and inner ear usually are caused by viruses. Most outer (swimmer's ear) and middle ear (otitis media) infections can be treated at home with remedies like warm compresses for ear pain relief, tea tree, ginger, or garlic oil drops. Symptoms of an outer ear (swimmer's ear) and middle ear infection include mild to severe ear pain, pus draining from the ear, swelling and redness in the ear, and hearing problems. Middle and inner ear infections may cause fever, and balance problems. Inner ear infections also may cause nausea, vomiting, vertigo, ringing in the ear, and labyrinthitis (inflammation of the inner ear). Most outer and middle ear infections do not need antibiotics. Inner ear infections should be treated by a doctor specializing in ear and hearing problems.
Sore throat (throat pain) usually is described as pain or discomfort in the throat area. A sore throat may be caused by bacterial infections, viral infections, toxins, irritants, trauma, or injury to the throat area. Common symptoms of a sore throat include a fever, cough, runny nose, hoarseness, earaches, sneezing, and body aches. Home remedies for a sore throat include warm soothing liquids and throat lozenges. OTC remedies for a sore throat include OTC pain relievers such as ibuprofen or acetaminophen. Antibiotics may be necessary for some cases of sore throat.
Sexually Transmitted Diseases in Women (STDs)
Sexually transmitted diseases (STDs) are among the most common infectious diseases in the United States. STDs can be spread through any type of sexual activity involving the sex organs, the anus or mouth, or through contact with blood during sexual activity. Examples of STDs include, chancroid, chlamydia, gonorrhea, granuloma inguinale, lymphogranuloma venereum, syphilis, genital herpes, genital warts, trichomoniasis, pubic lice (crabs), and scabies. Treatment is generally with antibiotics; however, some STDs that go untreated can lead to death.
Laryngitis is an inflammation of the voice box (vocal cords). The most common cause of acute laryngitis is infection, which inflames the vocal cords. Symptoms may vary from degree of laryngitis and age of the person (laryngitis in infants and children is more commonly caused by croup). Common symptoms include a "barky" cough, a hoarse cough, fever, cold, runny nose, dry cough, and loss of voice. Chronic laryngitis generally lasts more than three weeks. Causes other than infection include smoking, excess coughing, GERD, and more. Treatment depends on the cause of laryngitis.
Gonorrhea In Women
Gonorrhea is a bacterial infection transmitted during sexual contact. In women, symptoms include a yellow vaginal discharge, burning or frequent urination, and redness, swelling, burning and itching of the vaginal area. Gonorrhea can be treated with injectable (penicillin) or oral medications.

Is Pneumonia Contagious?
Pneumonia is inflammation of the lung usually caused by bacterial or viral infection (rarely, also by fungi) that causes the air sacs to fill with pus. If inflammation affects both lungs, the infection is termed double pneumonia. If it affects one lung, it is termed single pneumonia. If it affects only a certain lobe of a lung it's termed lobar pneumonia. Most pneumonias are caused by bacteria and viruses, but some pneumonias are caused by inhaling toxic chemicals that damage lung tissue.
