Does Everyone Take the Same Amount of Botulinum Toxin Type A?

Botulinum Toxin Type A Dosing for Head and Neck Spasms

The dose of botulinum toxin type A used for head and neck spasms (known medically as cervical dystonia) varies from person to person, and is based on the characteristics of your spasms and how you respond to botulinum toxin type A. There is no standard recommended dosage for this use.

Botulinum Toxin Type A Dosing for Eyelid Spasms

The recommended dose of botulinum toxin type A for eyelid spasms (known medically as blepharospasm) is 0.05 to 0.1 mL per each injection site (for a total of 1.25 to 2.5 units) into certain muscles that control the eyelids.

Botulinum Toxin Type A Dosing for Misaligned Eyes

The recommended dose of botulinum toxin type A for misaligned eyes (known medically as strabismus) is 0.05 to 0.15 mL per muscle. Special techniques must be used to ensure injection into the proper site. Often, this is done with a special needle that measures electrical signals from the muscle. Your healthcare provider may give you anesthetic eye drops a few minutes before your injection.

Botulinum Toxin Type A Dosing for Severe Sweating

For treating severe underarm sweating, the standard recommended dose is 50 units of botulinum toxin type A per underarm, given in several small injections. Before the injections, your healthcare provider may do a painless procedure that stains the area of increased sweating in order to target the therapy to the appropriate area.

General Information on Dosing With Botulinum Toxin Type A

Considerations for people taking botulinum toxin type A include the following:
  • The medication comes in injectable form. It is delivered directly into the muscles that are causing the problems. When treating severe sweating, botulinum toxin type A is injected directly into the underarm.
  • When treating misaligned eyes (strabismus), special techniques, sometimes using the electrical signals from the muscles, must be used to make sure that the injections are given in the right place.
  • Your healthcare provider may choose to use an anesthetic cream to numb your skin, but this is not necessary. If you are worried about pain, be sure to ask your healthcare provider about using an anesthetic cream.
  • The effects of botulinum toxin type A are not permanent. You will need to receive injections periodically in order to maintain the drug's effects.
  • For the medication to work properly, it must be taken as prescribed.
  • If you are unsure about anything related to botulinum toxin type A dosing, please talk to your doctor, nurse, or pharmacist.
