Trade Names:Bicillin C-R- Injection 600,000 units/dose (300,000 units each penicillin G benzathine and penicillin G procaine)- Injection 1,200,000 units/dose (600,000 units each penicillin G benzathine and penicillin G procaine)
Trade Names:Bicillin C-R 900/300- Injection 1,200,000 units/dose (900,000 units penicillin G benzathine and 300,000 units penicillin G procaine)
Inhibits mucopeptide synthesis of bacterial cell wall.
Following IM administration, peak blood levels occur within 3 h.
Protein binding is approximately 60%. Distribution varies widely throughout the body tissues with highest levels achieved in kidneys, liver, skin, and intestines.
Excreted rapidly by tubular excretion.
Excretion of the drug is considerably delayed in neonates, children, and individuals with renal function impairment.
Treatment of moderately severe infections caused by penicillin G-susceptible microorganisms that are susceptible to serum levels common to this particular dosage form; moderately severe to severe infections of the upper respiratory tract, scarlet fever, erysipelas, and skin and soft tissue infections caused by susceptible streptococci; moderately severe pneumonia and otitis media caused by susceptible organisms. Severe pneumonia, empyema, bacteremia, pericarditis, meningitis, peritonitis, and arthritis of pneumococcal etiology are better treated with penicillin G sodium or potassium during the acute stage. When high, sustained serum levels are required, use penicillin G sodium or potassium IM or IV. This drug should not be used in the treatment of venereal diseases, including bejel, gonorrhea, pinta, syphilis, and yaws.
Hypersensitivity to any penicillin or to procaine.

Allergic hypersensitivity (including skin eruptions [maculopapular to exfoliative dermatitis], urticaria, laryngeal edema, fever, eosinophilia); anaphylaxis (including shock and death); exacerbation of arthritis; injection-site reactions (including pain, inflammation, lump, abscess, necrosis, edema, hemorrhage, cellulitis, hypersensitivity, atrophy, ecchymosis, skin ulcer); joint disorder; myoglobinuria; neurovascular reactions (including warmth, vasospasm, pallor, mottling, gangrene, numbness and cyanosis of the extremities, neurovascular damage); periostitis; rhabdomyolysis; serum sickness-like reactions (including chills, fever, edema, arthralgia, prostration).
Not for IV use. Do not inject IV or add to other IV solutions. Inadvertent IV administration may result in cardiorespiratory arrest and death.
Take cultures at completion of therapy to determine whether streptococci have been eradicated.
Category B .
Excreted in breast milk.
Serious and sometimes fatal hypersensitivity reactions have occurred.
Prolonged use of antibiotics may result in bacterial or fungal overgrowth of nonsusceptible microorganisms.
Quadriceps femoris fibrosis and atrophy can occur following repeated IM injections of penicillin into the anterolateral thigh.
May occur because of overgrowth of clostridia; consider the possibility in patients in whom diarrhea develops.
Neuromuscular hyperirritability, convulsive seizures.
