Primary hyperhidrosis has no known cause. But secondary hyperhidrosis results from underlying health conditions including obesity, diabetes, anxiety disorders, hormonal changes, or certain medications.

Botox (Tox) contains botulinum toxin that temporarily blocks nerve signals stimulating sweat glands. This significantly reduces perspiration in treated areas for several months before repeat treatment is needed.

Neurotoxin effects for hyperhidrosis typically last 4-6 months. Repeat treatments are necessary to maintain reduced sweating. But individual duration varies based on metabolism and sweat gland activity.

Treatment is most commonly applied to underarms (axillae) but can also address excessive sweating in hands and feet. Multiple areas can be treated during the same session if needed.

Yes, but these side effects are generally minimal. Temporary bruising, swelling, or tenderness at injection sites may occur. Weakness in hand muscles is possible when treating palmar hyperhidrosis but typically resolves as the neurotoxin effect wears off.
