Antibiotic Resistance in Bangladesh: A Complete Guide

Walk into almost any pharmacy counter in Dhaka with a sore throat or mild fever, and there is a good chance you will walk out with an antibiotic — no prescription asked. A 2026 survey of urban and rural pharmacies in and around Dhaka found that only about 36% of antibiotic sales were made against a registered physician's prescription, and self-medication was even more common in rural outlets. This everyday convenience is quietly creating one of Bangladesh's most serious long-term health threats: antibiotics that no longer work when they are truly needed.

What Antibiotics Actually Do

Antibiotics kill or stop the growth of bacteria. They do nothing against viruses. This single fact explains most of the confusion around antibiotic use, because the great majority of everyday illnesses — the common cold, most sore throats, flu, and many cases of bronchitis — are caused by viruses, not bacteria. Taking an antibiotic for a viral illness will not shorten the illness or ease symptoms any faster; it only exposes your body to side effects and feeds antibiotic resistance for no benefit at all.

A common misconception is that the colour of mucus or phlegm — yellow or green versus clear — tells you whether an infection is bacterial. It does not. Colour change in mucus is a normal part of the immune response to many viral infections too, and on its own is not a reliable reason to start an antibiotic.

Why Misuse Matters: How Resistance Develops

Every time bacteria are exposed to an antibiotic, the ones that happen to survive — through a random genetic mutation or an acquired resistance gene — go on to multiply. Use an antibiotic when it is not needed, use the wrong one, or stop a course early once symptoms ease, and you give those surviving, hardier bacteria room to take over. Over time, and across a whole population doing this repeatedly, common infections become harder, slower, and more expensive to treat — sometimes untreatable with the medicines available at the local pharmacy.

To manage this risk, the World Health Organization groups antibiotics into three categories under its AWaRe classification:

• Access — first- or second-choice antibiotics for common infections (for example, amoxicillin for many respiratory and ear infections). These should be the default when an antibiotic is genuinely needed.
• Watch — broader-spectrum antibiotics (including azithromycin and ciprofloxacin) that carry a higher resistance risk and should be reserved for situations where an Access-group drug is not appropriate.
• Reserve — last-line antibiotics kept for confirmed, serious multidrug-resistant infections, normally used only in hospital under specialist guidance.

The classification is not about which drug is "stronger" — it reflects how much a drug's casual, widespread use accelerates resistance. In Bangladesh, Watch-group antibiotics such as azithromycin and ciprofloxacin are, in practice, among the most self-medicated drugs in the country, which is precisely the pattern global health authorities are trying to reverse.

Telling a Likely Viral Illness From One That May Need a Doctor

No one should self-diagnose a bacterial infection from home, but a few general patterns can help you decide whether to wait, manage symptoms at home, or seek medical advice:

• A simple cold or flu-like illness usually peaks within 3–5 days and resolves within about two weeks on its own, with rest, fluids, and symptom relief such as paracetamol for fever or pain.
• Fever that keeps climbing after day 3–4 instead of improving, or that returns after initially settling, deserves medical review rather than an automatic antibiotic.
• Localised, severe symptoms — one-sided ear pain with discharge, pus visibly on the tonsils with high fever and no cough, a markedly swollen and painful joint, cloudy or foul-smelling urine with burning and fever, or a wound that is increasingly red, swollen, and discharging — are the kinds of findings a doctor actually looks for before considering a bacterial cause likely.
• Difficulty breathing, confusion, a fever above 103°F/39.4°C that does not respond to paracetamol, or symptoms in a very young infant, a pregnant woman, or someone with a chronic illness always warrant prompt medical attention regardless of suspected cause.

The only way to reliably confirm a bacterial infection is a clinical assessment, and sometimes a test — a complete blood count, urine culture, throat swab, or similar — ordered by a qualified doctor.

The Antibiotics Bangladeshis Reach for Most — and the Numbers Behind Misuse

Local studies paint a consistent picture of which antibiotics end up being taken without a prescription. A survey in Rajshahi city found metronidazole topped the self-medication list at 50.43% of cases, followed by azithromycin (20.75%), ciprofloxacin (11.53%), amoxicillin (10.37%), and tetracycline (7.49%). Separately, hospital-use data lists ceftriaxone, cefixime, ciprofloxacin, azithromycin, and amoxicillin among the ten most-used antibiotics nationwide, with the injectable cephalosporin ceftriaxone the single most-used antibiotic outside intensive care units.

The consequence shows up directly in resistance data: a Dhaka-based study found that more than 80% of collected E. coli bacterial isolates — E. coli being a very common cause of urinary tract and gut infections — were already resistant to commonly used antibiotics including azithromycin, ciprofloxacin, amoxicillin, cefixime, and cefuroxime. A national community survey also found that only 56.1% of people who had recently taken antibiotics were even aware that antibiotic resistance exists as a problem, while 20.5% of recent antibiotic users had self-medicated rather than consulting a doctor.

What Goes Wrong When Antibiotics Are Misused or Stopped Early

Beyond fuelling resistance at a population level, individual misuse carries direct risks:

• Side effects without benefit: upset stomach, diarrhoea, and skin rash are the most common; some antibiotics disrupt the gut's beneficial bacteria badly enough that the effect can last for months after a single course, increasing susceptibility to yeast infections and digestive upset.
• Drug-specific risks: fluoroquinolones such as ciprofloxacin carry a rare but recognised risk of tendon inflammation or rupture and joint problems, and are generally avoided in children and during pregnancy unless there is no safer alternative.
• Masking a more serious illness: taking a leftover or borrowed antibiotic "just in case" can temporarily blunt symptoms of something like typhoid or a deeper infection, delaying proper diagnosis and treatment.
• Incomplete courses: stopping as soon as you feel better — rather than finishing exactly what a doctor prescribed — can leave partially resistant bacteria behind to multiply. The safest rule is simple: never change the length or dose of a course on your own; follow the prescriber's instructions exactly, and ask your doctor or pharmacist if you are unsure rather than deciding yourself.

Special Considerations

Children: many antibiotics come in child-specific oral suspensions, and dosing is weight-based — never estimate a child's dose from an adult tablet or from what worked for a sibling. Fluoroquinolones like ciprofloxacin are typically avoided in children unless a specialist decides the benefit outweighs the risk.

Pregnant and breastfeeding women: some commonly available antibiotics, including certain fluoroquinolones and tetracyclines, are avoided in pregnancy because of risks to the developing baby. Any antibiotic use in pregnancy should be doctor-directed.

Elderly patients and those with kidney or liver disease: many antibiotics are cleared through the kidneys or liver, and doses may need adjustment; self-medicating is riskier in this group because side effects and drug interactions (for example with blood thinners or diabetes medicines) are more likely.

Anyone with a known drug allergy: a past reaction — rash, swelling, breathing difficulty — to penicillin-type drugs (which includes amoxicillin) should always be mentioned to the prescriber or pharmacist before taking a new antibiotic.

Bangladesh's Policy Response

On paper, Bangladesh already restricts antibiotics to prescription-only sale: the National Drug Policy requires that antibiotics be dispensed only against a registered physician's prescription, and as a complete course rather than loose, partial quantities. In practice, enforcement has lagged — a 2019 High Court directive pushed regulators to curb over-the-counter antibiotic sales, after which the Directorate General of Drug Administration (DGDA) proposed a provision for a new drug act that would fine pharmacies for dispensing antibiotics without a doctor's prescription. A national AMR containment strategy covering 2022–2026 (succeeding an earlier 2017–2022 plan) is meant to tighten this further, alongside surveillance of resistance patterns in hospitals and communities.

How to Use Antibiotics Safely

• Take an antibiotic only when a qualified doctor has prescribed it for you, for this illness — never a leftover course, never one borrowed from a relative or neighbour.
• Tell your doctor or pharmacist about any known allergies, pregnancy, breastfeeding, or other medicines and chronic conditions before starting.
• Take the exact dose, at the times instructed, for the full length prescribed — do not stop early because you feel better, and do not extend the course yourself either.
• Never pressure a doctor for an antibiotic for a cold, flu, or mild sore throat; ask instead what else can relieve your symptoms while your body fights off a viral illness.
• Store antibiotics as directed (some liquid suspensions need refrigeration) and dispose of unused medicine rather than keeping it "for next time."
• Complete recommended vaccinations — for measles, typhoid, pneumococcal disease, and others — since preventing infections in the first place reduces how often antibiotics are needed at all.

Viral Illness vs. Bacterial Infection: A Quick Comparison

A typical viral upper respiratory illness involves a gradual onset, runny or stuffy nose, mild-to-moderate sore throat, cough, and generally improves steadily over 7–10 days without treatment. A bacterial infection more often has a sudden, localised, or worsening pattern — for example, a sore throat with high fever, no cough, and visible white patches on the tonsils; an ear infection with persistent severe pain and discharge; or a urinary infection with burning, frequency, and fever. When in doubt, especially if symptoms are getting worse after several days rather than better, a medical opinion — not a pharmacy guess — is the safer path.
