Iodine: Uses, Benefits, Precautions, and Side Effects

Iodine is a potent antiseptic agent whose primary active component is molecular iodine. Its antiseptic properties are well-established, making it a valuable tool in treating various skin conditions and wounds. When applied to large areas of skin, iodine exhibits a resorptive effect, influencing metabolic processes, enhancing dissimilation, and participating in the synthesis of thyroxine and triiodothyronine. The addition of ethyl alcohol slows iodine absorption, reducing its irritating effects on tissues.

Iodine demonstrates bactericidal activity against both Gram-positive and Gram-negative bacteria, showing particular effectiveness against Streptococcus spp. and Escherichia coli. It's also effective against pathogenic fungi and yeasts.

Uses:

• Inflammatory and infectious skin diseases
• Abrasions, cuts, and minor wounds
• Myositis and neuralgia
• Inflammatory infiltrates
• Pre-operative skin disinfection before injections, punctures, and catheterization

Precautions and Contraindications:

Iodine should be used with caution and is contraindicated in individuals with:

• Hypersensitivity to iodine
• Hyperthyroidism (thyrotoxicosis)
• Herpetiform dermatitis

Application and Dosage:

Iodine is applied topically to affected or areas requiring disinfection. For surgical site preparation, the skin should be swabbed twice with a sterile gauze pad soaked in the iodine solution. The total application time should be 4-6 minutes.

Side Effects:

• Skin irritation
• Allergic reactions (itching)
• With prolonged use on extensive wounds, iodism may occur, characterized by symptoms such as rhinitis, urticaria, angioedema, increased salivation, lacrimation, and acne.
