The Hidden Dangers of Unnecessary Dexamethasone (Dexa) Injections and Tablets: What Every Patient Should Know

Here's the part that makes misuse so convincing: dexamethasone works fast, and it works on almost anything involving inflammation — which includes the fever, body aches, and general misery of an ordinary viral illness. A patient who feels dramatically better within hours of an injection isn't imagining it. The steroid is genuinely suppressing the inflammatory response that's making them feel sick.

The problem is what that relief doesn't mean. Feeling better is not the same as the underlying viral infection being gone — the virus is often still present and still running its course. Worse, dexamethasone actively suppresses the immune response that's supposed to be fighting that virus, which is exactly backwards from what a sick body needs. Peer-reviewed case reports from Pakistan have documented this going seriously wrong: patients using unsupervised steroids for mild early COVID-19 symptoms who went on to develop mucormycosis, a rare but life-threatening fungal infection, particularly in patients with underlying diabetes.

The most common misuse pattern in Pakistan looks like this: a patient with a viral fever, flu, sore throat, or body aches — all self-limiting illnesses that resolve with rest and time — receives a steroid injection, often from an unqualified provider, and feels rapid relief. That relief reinforces the belief that the injection was necessary, and the pattern repeats with the next illness.

Research on Pakistan's healthcare system has documented a related pattern at scale: unsafe and unnecessary injection practices are unusually common, and unregulated "quack" providers — operating without medical qualifications — are a well-documented source of steroid misuse, particularly in rural areas with limited access to qualified physicians.

Dexamethasone has real, evidence-based uses. These include: severe allergic reactions and anaphylaxis, certain autoimmune and inflammatory conditions, some blood cancers and brain tumors (to reduce swelling around the tumor), croup in young children, and hospitalized COVID-19 patients who need supplemental oxygen (a WHO-recommended use, not a home-treatment one). In every one of these cases, a qualified physician is weighing a specific, diagnosed condition against the medicine's real risks — not treating a symptom in isolation.

Before agreeing to any injection for a common illness, it's reasonable to ask: what exactly is in this injection, and why is it needed for this specific illness? A qualified physician should be able to answer both questions clearly. If an injection is offered for an ordinary fever, flu, or body ache without a clear explanation of what it contains or why it's necessary, that's worth pausing on.

Seeking care from a qualified, registered physician — rather than an unregulated provider — is the single most protective step. Pakistan's own public health research has repeatedly identified unregulated "quack" practices as a major driver of steroid and injection misuse specifically because they operate outside routine medical judgment and follow-up. This isn't about distrust of medicine in general; it's about the specific, documented risk of treatment from providers without the training to weigh a medicine's real risks against its benefits.

For the ordinary viral illnesses steroids are often mistakenly used for — flu, common cold, mild viral fever, sore throat — the genuinely effective approach is unglamorous but well-supported: rest, fluids, and time. Paracetamol can help with fever and discomfort. Most of these illnesses resolve within a week to ten days without any injection at all.

Documented adverse effects of unnecessary or repeated steroid use include: a weakened immune response and increased susceptibility to infection; elevated blood sugar (a real danger for anyone with, or at risk of, diabetes); increased blood pressure and fluid retention; gastric irritation and, with repeated use, ulcers; mood changes ranging from irritability to genuine depressive symptoms with longer use; sleep disturbance; weight gain, especially around the face, neck, and abdomen; osteoporosis and weakened bones with repeated exposure; muscle weakness; adrenal suppression (the adrenal glands scaling back their own hormone production, which can be dangerous if steroids are then stopped suddenly); thin, fragile skin and delayed wound healing; and, with prolonged use, cataracts and glaucoma.

These aren't theoretical. Pakistani case reports have documented children developing Cushing's syndrome — including significant weight gain, a rounded "moon face," and stunted growth — after being treated with steroids by unqualified providers for ordinary childhood illnesses like viral cough. Adult cases of iatrogenic (medically-caused) Cushing syndrome from unsupervised steroid use have been documented too, sometimes only diagnosed after multiple organ systems were already affected.

If you've been receiving frequent steroid injections — for recurring fevers, body aches, or "weakness" — and have noticed unusual weight gain (especially around the face or abdomen), new or worsening high blood pressure, unexplained mood changes, slow-healing cuts, or unusual bruising, mention this history to a qualified physician directly and specifically. These can be signs the body has been affected by repeated steroid exposure, and they're worth a real evaluation, not another injection.

If you've been on any steroid for more than a few days and want to stop, don't stop abruptly — talk to a physician first. Suddenly discontinuing steroids after the adrenal glands have scaled back their own hormone production can itself cause a real medical problem (adrenal insufficiency), with symptoms including severe fatigue, nausea, and fever. This is precisely why steroids prescribed for a real medical reason are usually tapered down gradually, under supervision, rather than stopped all at once.
