Tetracycline Group of drugs


Lymecycline is a tetracycline derivative which blocks the access of bacterial aminoacyl-tRNA to the mRNA-ribosome complex by binding to the 30S ribosome subunit, preventing the addition of amino acids to the growing peptide chain in protein synthesis

  • Acne: the normal dose is one capsule once a day, preferably in the morning. Lymecycline capsules should always be taken with a glass of water. How long you will have to take Lymecycline capsules for will depend on how quickly your condition improves. For acne this will normally be a minimum of eight weeks.
  • Infections: For other infections the usual dose is one Lymecycline capsule twice a day. Your doctor may recommend a higher or lower dose; this depends upon the type and severity of the infection.
