Risks and Complications of Botox & Dysport - Hyperhidrosis

Every procedure involves a certain amount of risk, and it is important that you understand these risks and the possible complications associated with them. In addition, every procedure has limitations. An individual’s choice to undergo a procedure is based on the comparison of the risk to potential benefit. Although the majority of patients do not experience these complications, you should discuss each of them with your practitioner to make sure you understand the risks, potential complications, limitations, and consequences of BOTOX / DYSPORT injections.

Incomplete Block- It is possible to not experience a complete block of desired muscles. Additional injections to reach the desired level of block can be performed until the goal is achieved.

Bleeding and Bruising- It is possible, though unusual, to have a bleeding episode from a BOTOX / DYSPORT injection. Bruising in soft tissues may occur. Aspirin, anti-inflammatory medications, platelet inhibitors, anticoagulants, Vitamin E, Ginkgo Biloba, and other “herbs / homeopathic remedies” may contribute to a greater risk of a bleeding problem.  Do not take these for ten days before or after BOTOX / DYSPORT injections.

Damage to deeper structures- Deeper structures such as nerves and blood vessels may be damaged during the course of injection. Injury to deeper structures may be temporary or permanent.

Migration of BOTOX or DYSPORT – BOTOX / DYSPORT may migrate from its original injection site to other areas and produce temporary paralysis of other muscle groups or other unintended effects.

Pain – Discomfort associated with BOTOX / DYSPORT injections is usually short duration.

Skin disorders – Skin rash and swelling may rarely occur following BOTOX / DYSPORT injection.

Unknown risks – The long-term effect of BOTOX / DYSPORT on tissue is unknown. The risk and consequences of accidental intravascular injection of BOTOX are unknown and not predictable. There is the possibility of additional risk factors may be discovered.

Unsatisfactory result – There is the possibility of a poor or inadequate response from the BOTOX / DYSPORT L injection. Additional BOTOX / DYSPORT injections may be necessary.  Surgical procedures or treatments may be needed to improve skin wrinkles including those caused by muscle activity.

Allergic reactions – As with all biological products, allergic and systemic anaphylactic reactions may occur.  Allergic reactions may require additional treatment.

Antibodies to BOTOX or DYSPORT – The antibodies to BOTOX / DYSPORT may reduce the effectiveness of this material in subsequent injections.  The health significance of antibodies to BOTOX / DYSPORT is unknown.

Infection – Infection is extremely rare after BOTOX / DYSPORT injection.  Should an infection occur, additional treatment including antibiotics may be necessary.

Neuromuscular Disorders – Patients with peripheral motor neuropathic disorders (amyotrophic lateral sclerosis, myasthenia gravis, motor neuropathies) may be at greater risk of clinically significant side effects from BOTOX / DYSPORT.

Drug Interactions – The effect of BOTOX / DYSPORT may be potentiated by aminoglycoside antibiotics or other drugs known to interfere with neuromuscular transmission.

Pregnancy and nursing mothers – Animal reproduction studies have not been performed to determine if BOTOX / DYSPORT could produce fetal harm. It is not known if BOTOX / DYSPORT can be excreted in human milk.


There are many variable conditions in addition to risk and potential complications that may influence the long-term result of BOTOX / DYSPORT injections. Even though risks and complications occur infrequently, the risks cited are the ones that are particularly associated with BOTOX / DYSPORT injections.

Other complications and risks can occur but are even more uncommon. Should complications occur, additional surgery or other treatments may be necessary. The practice of medicine and surgery is not an exact science. Although good results are expected, there is no guarantee or warranty expressed or implied, on the results that may be obtained.
