Yes, cocaine is a legal, FDA-approved medication used in specific medical settings. It is classified as a Schedule II controlled substance, meaning it has a high potential for abuse but also has an accepted medical use in the United States. In practice, medical cocaine is a topical solution applied to the nasal passages before certain diagnostic procedures and surgeries.
What Medical Cocaine Is Used For
Medical cocaine is a liquid solution applied directly to the mucous membranes inside the nose. The FDA approved it specifically for inducing local anesthesia during diagnostic procedures and surgeries on or through the nasal cavities in adults. Ear, nose, and throat specialists are the primary users.
What makes cocaine unusual among local anesthetics is that it does two things at once. It numbs tissue by blocking nerve signals, the same way other local anesthetics work. But it also constricts blood vessels, which reduces bleeding at the surgical site. No other local anesthetic has this built-in dual action. Other drugs can achieve both effects, but they require combining a numbing agent with a separate blood vessel constrictor.
How It’s Sold and Administered
Medical cocaine comes in two branded products. Goprelto was approved by the FDA in December 2017, followed by Numbrino in January 2020. Both are cocaine hydrochloride solutions manufactured under strict pharmaceutical controls. The solution is available in 4% and 10% concentrations, with 4% being the most commonly used because it causes fewer side effects while still providing effective numbing.
Each milliliter of 4% solution contains 40 mg of cocaine hydrochloride. Most ENT specialists keep the total dose under 200 mg per patient, and a literature review suggests that staying at or below 1.5 mg per kilogram of body weight helps avoid systemic effects. These aren’t pills or powders you’d pick up at a pharmacy. The solution is used only in clinical settings, applied directly to nasal tissue by a physician, typically soaked into cotton pledgets or delivered as a spray.
Why Doctors Still Use It
Cocaine’s unique combination of numbing and blood vessel constriction made it valuable for nasal procedures where a clear, dry surgical field matters. That said, the DEA notes that more effective alternatives have been developed, and cocaine is now rarely used medically in the United States. Combinations of lidocaine with epinephrine, or decongestant sprays like oxymetazoline, can achieve similar results.
In one clinical trial comparing the three approaches before nasal intubation, 57% of patients treated with 10% cocaine had no bleeding, compared to 29% of those treated with lidocaine plus epinephrine. Oxymetazoline performed even better, with 86% of patients experiencing no bleeding. So while cocaine works, it isn’t necessarily the best option available today. Its continued approval gives surgeons one more tool for situations where they judge it the right choice.
Cardiovascular Risks During Use
Even when applied topically to nasal membranes, cocaine gets absorbed into the bloodstream and can affect the heart. It increases heart rate, raises blood pressure, and makes the heart work harder. These effects are dose-dependent, meaning higher doses produce stronger cardiovascular responses. This is a key reason the 4% solution is preferred over stronger concentrations.
Patients with high blood pressure, heart disease, or a history of stroke face greater risks. Severe adverse effects have been reported from doses as low as 20 mg in sensitive individuals, even though the estimated fatal dose is around 1,200 mg. The gap between those two numbers is wide, which is why careful dosing and patient screening matter. Combining cocaine with alcohol intensifies and prolongs its cardiovascular effects, and certain heart medications like beta-blockers can cause dangerous spikes in blood pressure when paired with cocaine.
How Medical Cocaine Differs From Street Cocaine
The active molecule is the same. The difference lies in purity, concentration, form, and context. Pharmaceutical cocaine hydrochloride is manufactured to precise standards, with known concentrations and no adulterants. Street cocaine varies wildly in purity and is frequently cut with other substances, some of which carry their own serious health risks.
Medical cocaine is also used in tiny, controlled amounts applied to a specific area of tissue, not inhaled, injected, or smoked. A typical medical dose stays well under 200 mg total. The route of administration and the dose both limit how much reaches the brain, which is why medical use doesn’t produce the intense euphoria associated with recreational cocaine, though some systemic absorption always occurs.
A Brief History of Cocaine in Medicine
Cocaine was actually the drug that launched modern local anesthesia. In 1884, a young Viennese eye doctor named Carl Koller placed a cocaine solution on the surface of the eye and demonstrated that it could make the cornea completely numb. This was a breakthrough. Before Koller’s discovery, eye surgery was performed on fully conscious, unsedated patients. His work inspired the development of safer synthetic local anesthetics like lidocaine and procaine, which gradually replaced cocaine in most medical applications. Nasal surgery remained one of the few areas where cocaine’s natural two-in-one properties kept it relevant into the 21st century.
