Excessive underarm sweating—hyperhidrosis—is more than just an inconvenience: it dictates clothing choices, meetings, and greetings. When antiperspirants are insufficient, botulinum toxin is an established and effective treatment: it temporarily blocks signal transmission to the sweat glands.
When treatment is an option
Treatment is advisable if excessive underarm sweating persists despite consistent use of antiperspirants. First, a doctor should determine whether there is an underlying secondary cause—such as hyperthyroidism or medication side effects. As a general practitioner, I take this evaluation seriously before initiating treatment.
Effect and process
After explanation, the preparation is injected superficially into the skin of both armpits in a fine grid pattern – for about 30 minutes. The effect begins after a few days, is fully developed after about two weeks, and usually lasts four to seven months, sometimes longer. Sweat production is significantly reduced; the body's temperature regulation remains unaffected, as only a small portion of the sweat glands are involved.
Risks and side effects
- Small welts and burning immediately after injection
- Bruises
- Rarely, temporary muscle weakness in the shoulder area
- Compensatory sweating in other areas is rare during underarm treatment.
- Treatment is not given during pregnancy and breastfeeding, or in cases of neuromuscular diseases.
Cost
Treating both armpits costs 570 € Each appointment (approximately 30 minutes). All prices can be found at [website address]. Prices. Please note: We will clarify whether a medical indication exists in a specific case during a consultation.
Frequently Asked Questions
How much does the treatment reduce sweating?
Clearly, most patients describe their underarms as largely dry for months. Giving an exact percentage would be unreliable, as the response varies from person to person.
Isn't that unhealthy — doesn't the body need to sweat?
The armpits contribute only a small part to temperature regulation. The body continues to sweat normally through the rest of the skin.
Does the treatment hurt?
The injections are superficial and brief. A numbing cream can be applied beforehand upon request.
How quickly does it work and how long does it last?
Treatment begins after a few days, reaches full effect after about two weeks, and usually lasts four to seven months. The treatment can then be repeated.
What should I have tried beforehand?
Aluminum chloride antiperspirants, when used correctly (in the evening, on dry skin), are effective. If that's not enough, botulinum toxin is the next sensible step—after medical consultation.
If sweating dominates your daily life, we will clarify in the initial consultation whether the treatment is suitable for you.
