Indication
LETYBO® is a prescription medicine for adults that is injected into muscles to temporarily improve the look of moderate to severe frown lines between the eyebrows (glabellar lines).
Important Safety Information
LETYBO® may cause serious side effects that can be life threatening. Call your healthcare provider or get medical help right away if you have any of these problems after treatment with LETYBO®:
- Problems swallowing, speaking, or breathing, due to weakening of associated muscles can be severe and result in loss of life. You are at the highest risk if these problems are pre-existing before injection. Swallowing problems may last for several months.
- Spread of toxin effects. The effect of botulinum toxin may affect areas away from the injection site and cause serious symptoms that include loss of strength and all-over muscle weakness, double vision, blurred vision and drooping eyelids, hoarseness or change or loss of voice, trouble saying words clearly, loss of bladder control, trouble breathing, and trouble swallowing.
Do not receive LETYBO® if you are allergic to any of the ingredients in LETYBO® (see Medication Guide for ingredients); had an allergic reaction to any other botulinum toxin product such as MYOBLOC® (rimabotulinumtoxinB), BOTOX®/BOTOX® COSMETIC (onabotulinumtoxinA), DYSPORT® (abobotulinumtoxinA), XEOMIN® (incobotulinumtoxinA), JEUVEAU® (prabotulinumtoxinA-xvfs), or DAXXIFY® (daxibotulinumtoxinA-lanm); or have a skin infection at the planned injection site.
LETYBO® dosing units are not the same as, or comparable to, any other botulinum toxin product.
Tell your healthcare provider about all your medical conditions, including side effects from botulinum toxin products, including dry eye; breathing, swallowing, bleeding, or heart problems; plans to have surgery; weakness of forehead muscles, drooping eyelids; have had surgery on your face; are pregnant or breastfeeding or plan to become pregnant or breastfeed.
Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Using LETYBO® with certain other medicines may cause serious side effects. Do not start any new medicines until you have told your healthcare provider that you have received LETYBO® in the past.
Especially tell your healthcare provider if you have received any other botulinum toxin product in the last 4 months or any in the past, and exactly which product you received (such as MYOBLOC®, BOTOX®/BOTOX® COSMETIC, DYSPORT®, XEOMIN®, JEUVEAU®, or DAXXIFY®). LETYBO® may cause serious side effects, including allergic reactions (such as itching, rash, hives, wheezing, trouble breathing, or dizziness or feeling faint), heart problems (such as irregular heartbeat and heart attack), and eye problems (including dry eye, reduced blinking, and corneal problems). Tell your healthcare provider or get help right away if you experience a serious side effect. No serious side events of distant spread of toxin effect associated with dermatologic use of LETYBO® have been reported in clinical studies at the dose of 20 Units for glabellar lines. The most common side effect of LETYBO® was headache.
These are not all the possible side effects of LETYBO®. For more information, see the full Prescribing Information including Boxed Warning, and refer to the Medication Guide or talk with your doctor.
