Usually, ichthyolipid mostly refers to ichthyolipid ointment, which is a russet viscous liquid with a charred asphalt-like odor when applied externally, and is usually used on unpurulent wounds, or on affected areas before the inflammation matures, to provide an anti-purulent effect. Ichthyolipid ointment is an anti-inflammatory and antiseptic drug with mild irritation, which is antibacterial, anti-inflammatory, inhibits the exudation of secretions, and antiseptic. After the patient uses this medicine, the affected area is cleared of bacteria and thus the pus is eliminated, and it can be used for the treatment of boils, dermatitis, cellulitis, lymphadenitis, and otitis externa. In addition, ichthyolipid ointment has the effect of contributing to keratin and local vasoconstriction. Occasionally, skin irritation and allergic reactions, followed by contact dermatitis, can be seen during the use of ichthyolipid cream, therefore, patients should confirm whether they are allergic to this drug before use. In addition, this drug produces resinous lumps in contact with acid and emits ammonia gas when combined with alkaline substances, so it is contraindicated to use it with acid and alkaline ingredients. Since ichthyolipid cream is irritating to the skin, avoid contact with eyes when using it and do not use it on broken skin. If the skin breaks down during use, you need to avoid the wound and apply it around it. If there are uncomfortable symptoms such as itching, redness, swelling and burning sensation at the site of application, the drug should be stopped and cleaned immediately and go to the hospital for consultation. Generally, continuous use should not exceed 1 week. If symptoms are not relieved, you need to contact your doctor for consultation as soon as possible and change other symptomatic medications in time. In addition, children need to be used under parental supervision to avoid adverse consequences.
