Botox is used for reducing facial lines, but it is also an FDA-approved treatment option for certain cases of excessive sweating, known as hyperhidrosis. For patients who have not found adequate relief with prescription-strength antiperspirants, Botox may help by temporarily blocking the nerve signals that activate sweat glands. Here is more information on Botox for hyperhidrosis:
Determining Whether Botox Is Appropriate
Botulinum toxin is generally recommended for people with primary focal hyperhidrosis. This type of hyperhidrosis affects specific body areas, and it is not caused by another medical condition or medication. If over-the-counter antiperspirants or prescription treatments haven’t worked, botulinum toxin injections may be a helpful next step.
The U.S. Food and Drug Administration (FDA) has approved Botox for the treatment of excessive underarm sweating. Medical professionals also use it off-label for other areas, including the palms, feet, and face. Your doctor will evaluate your symptoms and review your medical history to determine whether Botox is appropriate for you.
Reducing Excess Sweating
Botox targets the nerves that signal your sweat glands to produce moisture. Here’s how the treatment works:
- Blocks nerve signals: Botox contains botulinum toxin, which prevents the release of acetylcholine. When acetylcholine is blocked, the glands stop producing sweat.
- Targets specific areas: The injections are placed directly into the affected area. This localized approach means that only the treated region experiences reduced sweating.
- Provides temporary relief: The effects of Botox are not permanent. Nerve activity gradually resumes over time, so repeat treatments are necessary to maintain results.
Botox does not cure hyperhidrosis, but it offers temporary relief that can significantly improve daily comfort and confidence.
Preparing for Treatment
Here’s what patients can expect during a session for hyperhidrosis:
- Preparation: The treatment area is cleaned, and a topical numbing cream may be applied to reduce discomfort. Some doctors also use ice to numb the skin before injections.
- Injection process: The doctor uses a fine needle to inject small amounts of Botox into multiple points across the treatment area. The number of injections depends on the size and location of the area being treated.
- Discomfort level: Most patients describe the sensation as a mild pinch or stinging. If you’re concerned about pain, discuss numbing options with your doctor beforehand.
You can return to your normal activities right away, but avoid intense exercise or heat exposure to allow the treatment to settle.
Managing Results and Risks
Botox for hyperhidrosis delivers noticeable results, but the treatment comes with some limitations and potential side effects. Sweating typically decreases within two to four days after the injections, and full results appear within two weeks. Most patients experience a significant reduction in sweating that lasts three to four months. Some people may notice effects for up to a year, while others may need retreatment sooner.
Side effects are generally mild and temporary. Common reactions include soreness, swelling, or bruising at the injection sites. In rare cases, patients may experience muscle weakness in the treated area, especially when Botox is injected into the hands or feet. This weakness usually resolves within a few weeks.
