Cefdinir is a cephalosporin antibiotic commonly prescribed to treat bacterial infections. While generally safe and effective, like all medications, it can cause side effects. This article provides a comprehensive overview of the potential side effects of cefdinir, ranging from common to rare occurrences. Understanding these potential side effects allows you to discuss any concerns with your doctor and make informed decisions about your treatment.

Common Side Effects of Cefdinir

Most people taking cefdinir experience mild side effects. These typically resolve on their own without needing medical intervention. However, it's crucial to report any side effects to your doctor, even if they seem minor. Common side effects include:

Diarrhea: This is a frequently reported side effect. If it becomes severe or persistent, contact your doctor immediately, as it could indicate a more serious problem. Staying hydrated is crucial.
Nausea and Vomiting: These gastrointestinal disturbances are also relatively common. Taking cefdinir with food can sometimes help alleviate these symptoms.
Abdominal Pain: Mild abdominal discomfort is possible.
Headache: Some individuals experience headaches while taking cefdinir. Over-the-counter pain relievers may offer relief, but consult your doctor if headaches are severe or persistent.
Dizziness: Feeling lightheaded or dizzy is another potential side effect. Avoid activities that require alertness, such as driving or operating machinery, if you experience dizziness.
Rash: A mild skin rash can occur in some individuals. If a rash develops, especially if accompanied by itching or swelling, contact your doctor immediately.

Less Common but Important Side Effects of Cefdinir

While less frequent, these side effects require attention and prompt medical consultation:

Vaginal Yeast Infection (Candidiasis): Antibiotics can disrupt the natural balance of bacteria in the body, leading to yeast overgrowth. This is more common in women.
Pseudomembranous Colitis: This is a serious intestinal infection caused by the overgrowth of Clostridium difficile bacteria. Symptoms include severe diarrhea, abdominal cramping, and fever. Seek immediate medical attention if you experience these symptoms.
Allergic Reactions: Although rare, serious allergic reactions can occur. These can manifest as hives, swelling (especially of the face, lips, or tongue), difficulty breathing, or a rapid heartbeat. This is a medical emergency requiring immediate attention.

Serious but Rare Side Effects of Cefdinir

These side effects are uncommon but warrant immediate medical attention:

Seizures: In rare instances, cefdinir can trigger seizures, particularly in individuals with a history of seizures or kidney problems.
Jaundice: Yellowing of the skin or eyes can indicate liver problems.
Severe Skin Reactions: Such as Stevens-Johnson syndrome or toxic epidermal necrolysis, are rare but potentially life-threatening. These conditions require immediate medical attention.
