Benzathine Penicillin Injection Price in Bangladesh

Benzathine penicillin is a long-acting form of penicillin G that dissolves slowly from a deep muscle injection, keeping a low level of antibiotic in the blood for weeks. In Bangladesh its most important job is preventing repeat attacks of rheumatic fever in children and young adults whose heart valves have already been affected. It also treats syphilis and some streptococcal throat infections. Each vial holds a powder that a trained health worker mixes and injects.

Long Acting Penicillin sits under Anti-Bacterial.

How Benzathine Penicillin Is Used

Use	Usual pattern	Who gives it
Preventing rheumatic fever from returning	One injection every three to four weeks, for years	A clinic or trained health worker
Early syphilis	Usually a single injection	A doctor, after a blood test
Late or latent syphilis	Weekly injections for a set course	A doctor, with follow-up blood tests
Strep throat when tablets are unreliable	A single injection	A doctor

Stopping Rheumatic Heart Disease From Worsening

Rheumatic fever follows an untreated streptococcal throat infection, and each new attack can scar the heart valves a little more. Regular benzathine penicillin keeps those bacteria from taking hold, so the valves are spared further damage. Doctors usually continue the injections for many years, often into adulthood, and for longer when a valve is already narrowed or leaking. A child who has had rheumatic fever even once is a candidate for this protection.

Why the Schedule Cannot Slip

The antibiotic level falls steadily after each injection, so by the end of the interval protection is thin. An injection given late leaves a window in which a sore throat can trigger another attack. Keeping the next date on a card, linking visits to a regular clinic day and planning around exams, travel or Eid holidays helps families stay on time. If a dose is missed, arrange it as soon as possible rather than waiting.

A Deep Muscle Injection by Trained Staff

Benzathine penicillin is a thick, milky suspension that must go deep into a large muscle, usually the upper outer buttock or, in small children, the outer thigh. It is pushed in slowly through a wide needle. It must never enter a vein or artery, where it can cause serious harm, so the person giving it checks the needle position first. For this reason it belongs in a clinic, health centre or hospital, never at home.

Pain at the Injection Site

Most people feel a deep ache where the injection went in, and the leg may feel stiff for a day or two. Walking gently afterwards, a warm cloth on the area and paracetamol help. Some clinicians mix the powder with a local anaesthetic to ease the sting, which is a clinical decision. Children who dread the needle cope better when told honestly what to expect, and when the visit ends with something they look forward to.

Allergy Questions and Observation

Before the first injection, staff ask about any earlier reaction to penicillin, amoxicillin or other related antibiotics. Some clinics also perform a small skin test. Serious allergic reactions are uncommon but can come on within minutes, so patients are usually asked to wait at the clinic for around half an hour afterwards, where adrenaline is ready. A rash or swelling after any earlier dose must be mentioned every time, even years later.

Treating Syphilis

Early syphilis, including a painless genital sore or a body rash, is usually treated with a single injection, while infection of longer standing needs a weekly course. Within hours, some people develop fever, chills and aches as the bacteria die off; this passes within a day and is not an allergy. Sexual partners need testing and treatment too. In pregnancy, penicillin is the treatment that also protects the baby from infection.

Reactions That Need Urgent Help

• Breathlessness, wheezing or tightness in the throat soon after the injection.
• Swelling of the face or lips, or hives spreading over the body.
• Faintness, a weak pulse or sudden confusion.
• A cold, pale or very painful leg after a buttock or thigh injection.

When Daily Tablets Are the Alternative

For people who cannot reach a clinic every few weeks, doctors sometimes prescribe penicillin V tablets taken twice daily instead. Tablets are easier to give but easier to forget, and missed days leave the heart unprotected, so injections remain the preferred route where possible. Penicillin V and the short-acting benzylpenicillin injection are on Benzylpenicillin & Phenoxymethyl Penicillin. The doctor decides which suits each child.

Benzathine Penicillin Injection Price in Bangladesh

Benzathine penicillin is an inexpensive medicine; the larger 12 lac vial costs more than the 6 lac one, and makers’ prices sit close together.

The powder is mixed with water for injection only at the moment of use, and the thick suspension it forms can block a fine needle, which is one reason it is handled by staff who give it often. Erythromycin and azithromycin, used when a penicillin allergy rules this injection out, are on Macrolides.

Before You Order

• Bring the injection card with past dates to every visit.
• Report any earlier reaction to penicillin or amoxicillin.
• Plan to wait at the clinic for the observation period.
• Expect a sore buttock or thigh for a day or two.
• Arrange partner testing after a syphilis diagnosis.
