Cefdinir is an antibiotic used to treat various bacterial infections, particularly those affecting the respiratory tract and skin. It belongs to the class of antibiotics known as cephalosporins. Like all antibiotics, cefdinir can cause side effects, although not everyone will experience them.
Common side effects of cefdinir 300 mg include:
Gastrointestinal Effects: The most common side effects are related to the digestive system and may include diarrhea, nausea, vomiting, abdominal pain, and indigestion.
Allergic Reactions: Some individuals may experience allergic reactions to cefdinir, which can manifest as rash, itching, swelling (especially of the face/tongue/throat), severe dizziness, or trouble breathing. Allergic reactions can be serious and require immediate medical attention.
Yeast Infections: Antibiotics like cefdinir can disrupt the natural balance of bacteria in the body, potentially leading to yeast infections, such as oral thrush (in the mouth) or vaginal yeast infections (in women).
Less common but more serious side effects of cefdinir may include:
Severe Skin Reactions: Rarely, cefdinir can cause severe skin reactions such as Stevens-Johnson syndrome or toxic epidermal necrolysis. These conditions are serious and require immediate medical attention.
Liver Problems: In some cases, cefdinir can affect liver function, causing elevated liver enzymes or hepatitis.
Blood Disorders: Very rarely, cefdinir can affect blood cells, leading to conditions such as leukopenia (low white blood cell count) or thrombocytopenia (low platelet count).
Kidney Problems: Although uncommon, cefdinir may rarely cause kidney-related side effects, such as acute interstitial nephritis.
It's important to take cefdinir exactly as prescribed by your healthcare provider to minimize the risk of side effects and to complete the full course of treatment, even if you start feeling better before finishing the medication. If you experience any unexpected or concerning symptoms while taking cefdinir, especially severe diarrhea, rash, or difficulty breathing, seek medical attention promptly.
