What is this drug?

Isopropyl alcohol is an antiseptic liquid used on the skin to kill germs and bacteria. It works by destroying the proteins and outer layers of germs on contact, making it effective for cleaning and disinfecting.

How it works

Denatures bacterial and fungal proteins by disrupting hydrogen bonds and precipitating cellular proteins, while also disrupting lipid membranes, resulting in rapid microbicidal and fungicidal activity. Additionally, evaporative cooling provides symptomatic relief of musculoskeletal discomfort through local anesthesia of sensory nerve endings.

What to watch out for

Keep far away from fire, stoves, candles, and cigarettes because isopropyl alcohol catches fire very easily, which is especially important in Nigerian homes that use kerosene stoves. Do not use it as a substitute for drinking alcohol or hand sanitizer meant for consumption, as swallowing even a small amount is poisonous. Buy only from reputable pharmacies and look for trusted brands like Hyenang Surgical Spirit or M & B Isopropyl Alcohol to ensure proper concentration and quality.

Serious Side Effects

Drug Interactions

Do not apply isopropyl alcohol on the skin at the same time as other topical creams or ointments, as it may increase absorption of those drugs or cause irritation. Avoid using it alongside other skin antiseptics like hydrogen peroxide on the same wound at the same time as they may cancel each other out.
