The rising trend of administering intravenous (IV) or intramuscular ‘brain tonic’ injections at home is raising serious medical concerns. While many believe these periodic treatments boost memory and prevent stroke, experts caution that self-prescribed neuro-enhancers are both financially wasteful and potentially life-threatening.
A recent case involving a woman in her 60s who routinely received ‘brain tonic’ injections every few months highlights this concerning habit. When she later developed dizziness, her family mistakenly attributed it to having paused her regular booster shots earlier that year. Associate Professor Dr. Nguyen Lan Hieu, Director of Hanoi Medical University Hospital, expressed deep concern over this flawed logic, noting that it reflects a widespread misconception treating medical injections as routine wellness supplements.
What Are ‘Brain Tonic’ Injections in Reality?
According to Dr. Nguyen Lan Hieu, ‘brain tonic’ is a colloquial term rather than a formal pharmaceutical category. The medications commonly referred to under this label are indicated only for specific neurological conditions and fall into three primary categories:
- Oxygen-utilization enhancers: Drugs such as Cerebrolysin, Piracetam, and Citicoline, which help brain cells utilize oxygen more effectively.
- Cerebral vasodilators: Agents like Cinnarizine that widen blood vessels in the brain.
- Combination formulations: Medications such as Phezam that combine both vasodilating and metabolic properties.
“In injectable form, these medications improve cerebral blood flow by dilating cranial vessels, while enhancing memory and sleep quality by optimizing oxygen consumption in brain tissues. They can aid recovery and minimize complications following brain surgery, traumatic brain injury, or acute stroke,” Dr. Hieu explained.
However, the expert emphasized that medical associations recommend these injectable drugs only with low levels of clinical evidence, and they are never mandatory first-line therapies. Crucially, no scientific authority recommends routine injections to prevent strokes or boost cognitive function in healthy individuals.

For individuals suffering from headaches, vertigo, or underlying cardiovascular issues, uncovering the root cause and receiving targeted medical treatment is essential, rather than relying on unproven injections.
Risks and Side Effects of Unsupervised Injections
Like any parenteral medication, brain tonics carry notable risks of adverse reactions. Patients may experience localized swelling, redness, pain, or itching at the injection site. Systemic side effects can include epigastric discomfort, nausea, vomiting, diarrhea, or profound drowsiness.
More critically, injectable therapies carry the risk of severe hypersensitivity reactions, including life-threatening anaphylaxis. When individuals self-administer these drugs or hire unqualified practitioners for home delivery, the absence of emergency resuscitation equipment can lead to fatal delays in treating acute complications.

Three Crucial Rules: Injections Are Not ‘Superior’ Medicine
Dr. Nguyen Lan Hieu outlines three essential principles for patients tempted by quick-fix cognitive injections:
1. No Routine Brain Injections for Healthy Adults Over 50
There is no medical rationale supporting routine prophylactic brain booster shots for healthy middle-aged or elderly adults. Prescribing or receiving such treatments without clear pathology contradicts professional guidelines and medical ethics.
2. Never Solicit Home IV or Injection Services Without Prescription
Calling unofficial healthcare workers to administer home infusions in the hope of improving academic focus, relieving mild dizziness, or warding off stroke is hazardous. Some unverified products lack safety certifications, and unmonitored infusions risk severe circulatory overload or shock.
3. Prefer Oral Medications Whenever Possible
When an individual can swallow and absorb medication normally, oral administration is always the preferred route. Nearly all cognitive support medications are available in oral tablet or capsule forms. Injectable routes are strictly reserved for critical care, acute hospital settings, or cases where the patient is unconscious.
Instead of seeking shortcuts through costly syringes, sustainable brain health relies on straightforward, scientifically proven habits: managing blood pressure, staying active with daily walking, prioritizing restorative sleep, and reducing dietary sodium. As modern pharmacology suggests, medications should be targeted, specific, and short-term—while genuine well-being stems from everyday lifestyle discipline.
