1. What is Ceclor MR and what is it used for

Ceclor MR contains the active substance cefaclor, which is an oral semi-synthetic antibiotic belonging to the cephalosporin group. Cephalosporins have a bactericidal effect, as they inhibit the synthesis of the bacterial cell wall.
Cefaclor is indicated for the treatment of the following infections caused by susceptible bacterial strains:

  • Acute bronchitis and exacerbation of chronic bronchitis caused by Streptococcus pneumoniae(strains with reduced susceptibility to penicillin are resistant), Haemophilus influenzae(including strains producing β-lactamases), Haemophilus parainfluenzae, Moraxella catarrhalis(including strains producing β-lactamases), Staphylococcus aureus(methicillin-resistant strains are resistant).
  • Pharyngitis and tonsillitis caused by Streptococcus pyogenes(group A streptococci).
  • Pneumonia caused by Streptococcus pneumoniae(strains with reduced susceptibility to penicillin are resistant), Haemophilus influenzae(including strains producing β-lactamase) and Moraxella catarrhalis(including strains producing β-lactamase).
  • Sinusitis caused by Streptococcus pneumoniae(only penicillin-susceptible strains), Haemophilus influenzae(including strains producing β-lactamase), Moraxella catarrhalis(including strains producing β-lactamase).
  • Uncomplicated lower urinary tract infections, including cystitis and asymptomatic bacteriuria, caused by Escherichia coli, Klebsiella pneumoniae, Proteus mirabilisand Staphylococcus saprophyticus.
  • Skin and soft tissue infections caused by Streptococcus pyogenes(group A streptococci), Staphylococcus aureus(including β-lactamase-producing strains, methicillin-resistant strains are resistant) and Staphylococcus epidermidis(including β-lactamase-producing strains, methicillin-resistant strains are resistant).

Before starting treatment, appropriate tests should be carried out to demonstrate the susceptibility of the microorganisms to cefaclor.

2. Important information before taking Ceclor MR

When not to take Ceclor MR

  • if you are allergic to the active substance - cefaclor (or other cephalosporins) or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Before taking Ceclor MR, discuss it with your doctor or pharmacist

  • if you are allergic to antibiotics, including penicillins and cephalosporins, as well as any other medicines. Symptoms of an allergic reaction may include: rash, itching, swelling and sudden difficulty breathing
  • if you have kidney disease and are undergoing dialysis
  • if you have had colitis (a type of severe diarrhea) in the past. If you experience diarrhea during treatment, you should inform your doctor, as it may be a sign of pseudomembranous colitis. The doctor will decide on further action. You should not take anti-diarrheal medicines
  • if you have diabetes, as Ceclor MR may affect the results of urine tests for sugar.

Prolonged use of cefaclor may lead to the proliferation of resistant microorganisms. If a secondary infection occurs during treatment, you should inform your doctor, who will decide on further action and prescribe appropriate treatment.
Before having a blood test, you should inform your doctor that you are taking Ceclor MR, as it may affect the results of some tests.
You should consult your doctor if the above warnings apply to your past situation.

Ceclor MR and other medicines

Inform your doctor or pharmacist about all medicines you are taking, have recently taken, or plan to take.
Rarely, in patients taking cefaclor and anticoagulant medicines (e.g., warfarin or acenocoumarol), an increase in the effect of these medicines may occur.
The renal excretion of cefaclor, like that of other β-lactam antibiotics, is inhibited by probenecid.
During treatment with cephalosporins, cases of a positive (sometimes false-positive) Coombs test have been reported.
Ceclor MR may cause a false-positive result in the glucose test in urine using Benedict's solution or Fehling's test and copper sulfate tablets.

Children

The safety and efficacy of Ceclor MR in children have not been established. A cephalosporin antibiotic is available for children in the form of an oral suspension.

Pregnancy and breastfeeding

4. Possible side effects

Like all medicines, Ceclor MR can cause side effects, although not everybody gets them.
If you experience itching, redness, or swelling of the skin, joint pain, headache, sudden difficulty breathing, or a feeling of weakness, stop taking the medicine and contact your doctor immediately.
During clinical trials with cefaclor, most of the observed side effects were transient and mild. In 1.7% of patients, side effects related to the use of the medicine occurred, which required discontinuation of treatment. The following side effects have been reported during clinical trials. The frequency of side effects was less than 1% (less than 1 in 100 patients), except for those listed below:
Gastrointestinal disorders
Frequent side effects included: diarrhea, nausea, vomiting, and indigestion.
Immune system disorders
Frequent side effects included: rash, urticaria, or itching.
Very rare cases of a reaction similar to serum sickness have been reported.
During treatment with cefaclor, symptoms similar to serum sickness (multiform erythema, rash, and other skin symptoms with concurrent arthritis or arthralgia, with or without fever) have been observed. Rarely, lymphadenopathy and proteinuria occurred. Isolated symptoms may occur, but they are not due to a serum sickness-like reaction. Serum sickness-like reactions are due to hypersensitivity and usually occur during or after cefaclor treatment. They can be alleviated by administering antihistamines and corticosteroids. No serious consequences of these reactions have been reported.
Blood and lymphatic system disorders
Eosinophilia (elevated count of one type of white blood cell - eosinophils).
Reproductive system and breast disorders
Frequent cases of candidiasis (thrush) and vulvovaginitis.
Other side effects have also been reported, but their relationship to the treatment has not been confirmed:
Nervous system disorders
Headache, dizziness, drowsiness.
Hepatobiliary disorders
Transient elevation of liver enzymes (aspartate aminotransferase and alanine aminotransferase, and alkaline phosphatase).
Renal and urinary disorders
Transient elevation of blood urea nitrogen and creatinine levels.
Investigations
Transient thrombocytopenia (low platelet count), leukopenia, and lymphocytosis (low white blood cell count), neutropenia (low granulocyte count), and abnormal urine test results.
In addition to the side effects reported by patients taking Ceclor MR, the following side effects have been observed in patients taking cefaclor: erythema multiforme, fever, anaphylaxis (may occur more frequently in patients allergic to penicillin), Stevens-Johnson syndrome (erythema multiforme characterized by blisters on mucous membranes, mainly in the mouth and genital organs), positive Coombs test, and genital itching. Symptoms of pseudomembranous colitis (a disease that usually occurs after antibiotic treatment, resulting from the proliferation of Clostridium difficilein the intestine and the action of toxins produced by it) may occur during or after antibiotic treatment. Anaphylactoid reactions may occur as isolated symptoms, e.g., angioedema, weakness, swelling (including facial and limb swelling), shortness of breath, paresthesia (tingling sensation), fainting, or vasodilation. Rarely, symptoms of hypersensitivity may persist for several months.
In patients taking cefaclor, the following side effects have been reported rarely:
Toxic epidermal necrolysis (toxic skin necrosis), transient interstitial nephritis, liver function disorders, cholestatic jaundice, increased prothrombin time in patients taking cefaclor and warfarin, transient hyperactivity, excitement, nervousness, insomnia, hallucinations, increased tension, aplastic anemia, agranulocytosis, and hemolytic anemia.
Side effects reported by patients taking other β-lactam antibiotics:
pseudomembranous colitis, renal function disorders, and toxic nephropathy. Some β-lactam antibiotics have been associated with the ability to cause seizures, especially in patients with impaired renal function taking standard doses of cefaclor. If seizures occur during treatment with cefaclor, discontinue the medicinal product and contact your doctor immediately, who may prescribe antiepileptic drugs.
