Cefadroxil
Duracef contains cefadroxil, an antibiotic belonging to the cephalosporin group, which has a bactericidal effect on many Gram-positive and Gram-negative bacteria. The mechanism of action involves inhibiting the synthesis of the bacterial cell wall.
Cefadroxil is indicated for the treatment of the following infections, provided they are caused by susceptible bacterial strains:
(It has been shown that in the prevention of rheumatic fever, intramuscular administration of penicillin is effective. Duracef generally effectively eliminates streptococci from the oral cavity and pharynx. However, there is no data on the effectiveness of the drug in preventing recurrence of rheumatic fever).
Before starting treatment with Duracef, discuss it with your doctor or pharmacist.
If Duracef is to be used in patients who are hypersensitive to penicillins, it should be taken into account that a person hypersensitive to one beta-lactam antibiotic may also be allergic to other antibiotics in this group (so-called cross-hypersensitivity). Such reactions may occur in up to 10% of the patient population who have ever had a hypersensitivity reaction to penicillin.
In the event of an allergic reaction to Duracef, treatment should be discontinued.
In the event of severe, acute symptoms of hypersensitivity, rapid administration of special treatment may be necessary.
With the use of most antibacterial drugs, including Duracef, there have been reports of diarrhea associated with Clostridium difficileinfection, which can range from mild diarrhea to life-threatening colitis. Therefore, if the patient experiences diarrhea while taking Duracef or after its completion, they should inform their doctor. The doctor may decide to discontinue the use of the drug if diarrhea occurs during treatment and, if necessary, prescribe appropriate treatment.
Caution should be exercised when using Duracef in patients with renal impairment.
In patients with known or suspected renal impairment, careful observation and laboratory tests are necessary before and during treatment with Duracef.
Prolonged use of Duracef may lead to the development of resistant bacterial flora. Close monitoring of the patient is necessary. If a secondary infection occurs during treatment with Duracef, the patient should consult a doctor who will take appropriate measures.
During treatment with cephalosporin antibiotics, Coombs' test results may be positive.
Results of hematological tests or antoglobulin tests and Coombs' test, used for cross-matching in transfusiology, may be positive in newborns whose mothers were treated with cephalosporin antibiotics before delivery.
The drug should be used with caution in patients who have had gastrointestinal diseases, especially colitis.
Tell your doctor about all medicines you are taking or have recently taken, as well as any medicines you plan to take.
Probenecid (used in gout) may increase the concentration of cefadroxil in the blood.
Duracef can be taken independently of meals, as food does not affect its bioavailability. Taking the drug during meals reduces nausea and does not weaken absorption.
If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult their doctor or pharmacist before taking this medicine. Animal studies have not shown any harmful effects on fetal development; however, there is a lack of adequately documented and controlled studies in pregnant women, and therefore Duracef may only be used during pregnancy if absolutely necessary.
Cefadroxil passes into breast milk, so caution is necessary when administering Duracef to breastfeeding mothers.
Duracef does not affect the ability to drive or operate machines.
This medicine contains lactose monohydrate. If the patient has previously been diagnosed with intolerance to some sugars, they should contact their doctor before taking the medicine.
This medicine should always be taken exactly as advised by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist.
Duracef is administered once or twice a day orally, depending on the type and severity of the infection.
The drug should be taken for at least 48-72 hours after the disappearance of clinical symptoms or confirmation of the elimination of microorganisms. Treatment of infections caused by beta-hemolytic streptococci should last at least 10 days. In severe infections (e.g., osteomyelitis), it may be necessary to administer the drug for at least 4-6 weeks.
Duracef can be taken independently of meals, as food does not affect the absorption of the active substance.

Children are usually given a daily dose of 25 to 50 mg/kg body weight (in osteomyelitis and bacterial arthritis - 50 mg/kg body weight per day) in two equal doses (every 12 hours), and in pharyngitis, tonsillitis, and scarlet fever - in a single daily dose*.
Children with a body weight below 10 kg and those having difficulty swallowing capsules are given cefadroxil in the form of a suspension.
*Only in pharyngitis, tonsillitis, or scarlet fever
In patients with renal impairment, the doctor will determine the dosage of Duracef based on creatinine clearance.
Body weight (kg) | Hard capsules 500 mg |
| 1 capsule once a day* |
| 1 capsule twice a day |
Creatinine clearance (in ml/min/1.73 m2 body surface area) | Serum creatinine concentration (mg/dl) | Initial dose | Maintenance dose | Dosing interval |
50-25 | 14-25 | 1 g | 500 mg | 12 h |
10-25 | 25-56 | 1 g | 500 mg | 24 h |
0-10 | >56 | 1 g | 500 mg | 36 h |
Patients with a creatinine clearance of more than 50 ml/min/1.73 m2 body surface area can be treated as patients with normal renal function.
No symptoms of overdose have been observed after ingestion of cefadroxil at a dose of up to 250 mg/kg body weight (recommended is observation of the patient and possible symptomatic treatment). In case of ingestion of cefadroxil at a dose above 250 mg/kg body weight, it is recommended to empty the stomach (induce vomiting or gastric lavage).
Like all medicines, Duracef can cause side effects, although not everybody gets them.
The side effects observed after administration of cefadroxil are similar to those observed after administration of other cephalosporins.
The frequency of the above-mentioned severe side effects is unknown (cannot be estimated from the available data).
Additionally, during clinical trials and after the drug was placed on the market, the following side effects have been reported:
