Hyperhidrosis is a medical condition characterized by excessive sweating in certain areas of the body, such as the armpits, palms, or feet. It can be embarrassing and interfere with daily activities. Many people suffer from excessive underarm sweating regardless of their body temperature. People with hyperhidrosis may present severe underarm sweating even when they are cold or stressed. Sometimes topical antiperspirants are not enough to combat axillary hyperhidrosis.
Injections of botulinum toxin (Botox) can be an effective treatment option for hyperhidrosis. Botox is injected into the underarms and blocks the signals from the nerves responsible for sweating, stopping the sweat glands from producing too much sweat. Hyperhidrosis may also occur in other parts of the body. Overactive sweat glands are common on the hands, forehead, and feet. In all cases, the treatment with botulinum toxin is an effective approach that can improve the patient’s quality of life.
What to Expect During a Treatment Session
Before your session, you’ll meet with an experienced healthcare provider who will review your medical history and conditions to decide if this is the best hyperhidrosis treatment for you.
Most clients require only one botulinum toxin treatment under each arm to see a decrease in sweating. The procedure usually takes about 30-45 minutes, and it is generally very safe with minor potential side effects.
We start by cleaning and marking the area of concern. The botulinum toxin injection is then administered about every 1.5-2 cm in the marked area. Each underarm area usually requires about 15-20 injections. People who receive underarm Botox injections can see results in as little as 3-5 days after treatment. However, it will take 2 weeks to see the full effects of this type of treatment for hyperhidrosis.
How Long Do the Results Last?
Depending on the individual, subsequent treatments are typically needed 4-6 months after the initial treatment. However, just like in most cases that involve botulinum toxin treatments, in time, our clients can go longer before requiring additional treatments. When performed correctly, a single axillary hyperhidrosis treatment can last up to 12 months.
Botox for Hyperhidrosis Aftercare
Individuals can go home immediately after the Botox treatment. They should avoid exercise, and not have hot baths or showers for the rest of the day. They can apply ice to the area and take a mild pain reliever if they have some tenderness. Normal activity can be resumed the following day. Patients should also avoid touching the treated area to prevent the toxin from spreading to other parts of the body.
Furthermore, it is recommended to avoid hot environments or activities that may cause excessive sweating for 24 hours after the treatment and to take aspirin, ibuprofen, or other blood-thinning medications for 24 hours after the treatment to minimize the risk of bruising.
