Evidence-based clinical answers to common patient questions

Can I use this gel on my face or open cuts?

You should only apply this gel to the exact skin areas prescribed by your doctor. Avoid applying it to open wounds, deep cuts, or directly near your eyes unless specifically instructed by your doctor.

What should I do if the gel gets into my eyes?

If accidental contact occurs, rinse your eyes thoroughly with clean tap water right away. If irritation, redness, or stinging persists, contact your eye doctor or visit an urgent care center for an evaluation.

Why does this medicine affect my thyroid tests?

Iodoquinol contains iodine, which is absorbed through your skin. This extra iodine can alter thyroid hormone levels in your blood, leading to inaccurate test results unless you stop using the gel beforehand as advised.

Is it normal for my skin to sting slightly after applying?

Mild tingling can sometimes happen on sensitive or inflamed skin. However, if you experience intense burning, a spreading rash, or signs of an allergic reaction, wash the gel off and call your doctor right away.

Can I stop using the gel as soon as my rash disappears?

No, you should complete the full course of treatment prescribed by your doctor. Stopping too early can allow the underlying infection or eczema to flare right back up again.
