If I Am Getting Botox for Hyperhidrosis, Would the Doctor Be Reusing a Bottle That Someone else Used? Most Likely Yes or No?

Do doctors reuse Botox vials when treating hyperhidrosis

+1
Botox (botulinum toxin) comes in 100 and 200 unit vials. Typically we use 100 units per armpit for hyperhidrosis, although occasionally we use 50 units per armpit. As such, there is never a need to reuse a vial of Botox, as we'll either use a 200 unit vial (in most cases), or the 100 unit vial.

Botox for sweating

+1

The amount of Botox needed to treat axillary hyperhidrosis is 50 units per side so it should be a new 100 unit bottle for you. Bottles of Botox should never be shared anyway, they are labeled single patient, and sharing is a violation.

Botox for hyperhidrosis

Greetings~

If you are being injected in the underarm area for hyperhidrosis the standard dose is 100 units (50 units per side).  A standard vial is 100 units so you should be receiving an entire vial to treat both underarms (1/2 per side).  Less than 50 units per side may not give you adequate results. So, quite simply, no...you should not be sharing a vial with someone else.

Good luck~

Botox Dosing for Hyperhidrosis

+1

Although a standard dose for hyperhidrosis would require a full 100 units (50 units each side), it's perfectly acceptable for a practitioner to dose more than one patient from one vial when using proper storage and techniques to ensure sterility.

Botox for hyperhidrosis( sweating)

Usually 50 units per side is what is needed to treat the area.  Most vials are 100 units or 50 units.  However, the vial is not cross contaminated and used in a multi-dose fashion performed using sterile technique.  In your case, it would probably be using one vial.

Botox For Excessive Sweating (Hyperhidrosis)

+1

Hyperhidrosis is a medical condition characterized by excessive sweating. Patients with this condition often complain of embarrassing stains on their shirts, or being reluctant to shake hands. Studies have shown that Botox is a safe and effective treatment for hyperhidrosis. Often, 50 units of Botox per area is used as a starting dose. As one vial of Botox contains 100 units, typically an entire vial is used during the first treatment. Some patients require more than 50 units per area. Physicians are taught reconstitute and prepare Botox injections in a sterile manner. There should be no risk of cross contamination if 2 patients receive Botox from the same vial.

Botox for Hyperhydrosis.

+1

The usual dosing for axillary hyperhydrosis (underarms) is 100 units of Botox Cosmetic. Soles of feet require a similar amount. This would mean a whole 100 unit vial or two 50 unit vials.

Reconstitution of vials of Botox are performed using sterile technique, as is withdrawal of the drug at the point of administration. There should be no concerns about cross contamination. I would ask your doctor for confirmation.

Botox for hyperhydrosis

For most hyperhydrosis patients, a 100 unit vial is required as each underarm takes about 50 units. Therefore, you should be receiving your "own" full vial.

Generally 100 units of BOTOX are used for hyperhydrosis.

+1

For the typical office this means a new vial is often used for a given patient.  However, it would also not be unusual for say 50 units of BOTOX to be drawn from an already reconstituted vial and for a new vial to be reconstituted for the second 50 unit amount.  When you say "used,"  it is important to understand that reconstituted vials can and should be handled in a sterile fashion so there is never any cross contamination.  If you are not sure if your doctor can handle a vial in a sterile fashion, you are probably getting service in the wrong place.

Likely "no"...

Hyperhidrosis requires use of the entire 100 unit vial. If you have concerns, you could easily ask your doctor next time you are in.
