DORYX® MPC (doxycycline hyclate delayed-release tablets) for the Adjunctive Treatment of Severe Acne*

  • A tetracycline-class antimicrobial indicated as adjunctive therapy for severe acne available in 60 mg  dosage strengths for flexible dosing options1
  • Similar to standard DORYX®, DORYX® MPC contains pH-sensitive enteric-coated pellets of doxycycline hyclate1
  • The modified polymer coat (MPC) of DORYX® MPC delays the absorption of doxycycline by approximately 15 to 20 minutes farther into the GI tract when compared to standard DORYX®1-3
    – This minimizes doxycycline exposure in the upper GI tract, including the esophagus and stomach
  • DORYX® MPC 120 tablets were proven bioequivalent to 100 mg of doxycycline
    – The further delayed release of DORYX® MPC results in approximately 86% bioavailability of doxycycline1

Selected Safety Information about DORYX® MPC (doxycycline hyclate delayed-release tablets)

Doxycycline is contraindicated in patients who have shown hypersensitivity to any of the tetracyclines. Tetracycline-class drugs, like DORYX® MPC (doxycycline hyclate delayed-release tablets), can cause fetal harm when administered to a pregnant woman. DORYX® MPC should be avoided if possible by nursing mothers, taking into account the importance of the drug to the mother. DORYX® MPC should not be used in children during tooth development (up to the age of 8 years). Concurrent use of tetracycline-class antibiotics with oral contraceptives may reduce their effectiveness.

Clostridium difficile associated diarrhea (CDAD) has been reported with nearly all antibacterial agents including doxycycline, and may range from mild diarrhea to fatal erythema.

Photosensitivity can occur with tetracycline-class drugs. DORYX® MPC patients should minimize or avoid excessive exposure to natural or artificial sunlight, and consider using sunscreen or sunblock. Advise patients to discontinue therapy at the first evidence of skin erythema.

Overgrowth of non-susceptible organisms, including fungi, may occur. DORYX® MPC should be discontinued if superinfection occurs and appropriate therapy instituted. Adverse reactions observed in patients receiving tetracyclines include anorexia, nausea, vomiting, diarrhea, rash, photosensitivity, urticaria and hemolytic anemia.

Intracranial Hypertension (IH) has been associated with the use of tetracyclines. Women of childbearing age who are overweight or have a history of IH are at greater risk for developing tetracycline-associated IH.

Adverse reactions observed in patients receiving tetracyclines include anorexia,  nausea, vomiting, diarrhea, rash, photosensitivity, urticaria, and hemolytic anemia.
