Aftercare: Botox for Hyperhidrosis

Once the anesthetic wears off, the injection sites on your palms may feel a bit sore for 1–2 hours. This passes quickly.

Rarely, grip strength in the treated palms and fingers may decrease very slightly — not enough to notice in daily life. If your work depends on fine hand movements, you may feel some awkwardness, so please discuss this with the doctor before treatment. Fine finger movements may feel a little off for a few days.

Don't touch or rub the injection sites for 3–4 hours. Washing your hands or face that evening is fine, but avoid handling food with bare hands or doing dishes on the day of treatment.

Uncommonly — in fewer than about 10% of people — mild flu-like symptoms (feeling warm, sore throat) can occur for a few days. It's not a health concern; it's the Botox taking effect. An over-the-counter pain reliever such as acetaminophen (Tylenol) usually helps.

Rarely, sweating decreases in the treated area but increases elsewhere, such as the face or chest.

The effect starts around day 3–4 and becomes clearly noticeable after about a week. It typically lasts 6 months or more, after which sweating gradually returns.

Botox hasn't been established as safe during pregnancy or breastfeeding, so we generally don't treat pregnant or breastfeeding patients.
