Why is this medication prescribed?

Bicillin CR is typically prescribed for the treatment of various bacterial infections, particularly those caused by susceptible strains of streptococcal bacteria. Here are some common conditions for which Bicillin CR may be prescribed:

• Strep Throat (Streptococcal Pharyngitis): Bicillin CR is often used as a first-line treatment for strep throat, especially in cases where oral antibiotics may not be suitable or effective.
• Rheumatic Fever Prophylaxis: It’s also used for the prevention of recurrent attacks of rheumatic fever and chorea in patients with a history of rheumatic fever or rheumatic heart disease.
• Syphilis: Bicillin CR is part of the treatment regimen for syphilis, particularly in cases where a long-acting antibiotic is preferred.
• Other Infections: In some cases, healthcare providers may prescribe Bicillin CR for other bacterial infections when appropriate, based on the specific bacterial strain and susceptibility testing.

How should this medicine be used?

Bicillin CR (Benzathine Penicillin G) is administered via intramuscular injection by a healthcare professional. Here’s a general guide on how it should be used:

• Preparation: Bicillin CR typically comes in the form of a powder that needs to be reconstituted with a diluent solution before injection. The healthcare provider will prepare the injection according to the manufacturer’s instructions.
• Injection Site: Bicillin CR is usually injected deeply into the muscle, typically the upper outer quadrant of the buttocks (the dorsogluteal muscle) or the mid-lateral thigh muscle. The injection site should be clean and free from any lesions or irritation.
• Dosage: The dosage of Bicillin CR depends on the condition being treated, the patient’s age, weight, and other factors. The healthcare provider will determine the appropriate dosage for each individual patient.
• Frequency: The frequency of Bicillin CR injections varies depending on the condition being treated. For example, in the treatment of streptococcal infections, a single injection may be sufficient, while for other conditions like syphilis, multiple injections over several weeks may be required.
• Follow-Up: After receiving a Bicillin CR injection, it’s essential to follow up with the healthcare provider as scheduled for monitoring of the infection and any potential side effects.
• Complete Course: It’s crucial to complete the full course of treatment as prescribed by the healthcare provider, even if symptoms improve before the medication is finished. Failure to complete the course of antibiotics can lead to incomplete eradication of the infection and may contribute to antibiotic resistance.
• Storage: Bicillin CR should be stored according to the manufacturer’s instructions, typically at room temperature away from light and moisture. Once reconstituted, it should be used promptly or discarded according to the healthcare provider’s instructions.

It’s essential to follow the healthcare provider’s instructions carefully when using Bicillin CR to ensure effective treatment and minimize the risk of complications. Always consult with a healthcare professional if you have any questions or concerns about the use of this medication.
