After botulinum toxin injections, use the instructions from your own treating clinician as the primary guide. The exact product, injection sites, dose, health history, and any reaction you develop can change what is appropriate. General information online cannot tell whether a specific symptom is expected or needs treatment.
What can happen after an injection?
Redness, swelling, soreness, or bruising can occur around an injection site. Some people report a headache. A neighboring muscle can occasionally become weak, which may temporarily affect an eyelid, eyebrow, or another nearby area. The type and likelihood of side effects vary by product and treatment area.
Before leaving the appointment, ask what reactions the clinician expects, how long you should monitor them, and how to reach the practice if something feels wrong. Do not assume that every new symptom is a routine part of treatment.
Follow product- and provider-specific instructions
The American Academy of Dermatology advises patients not to rub or massage injected areas and to avoid pressing or rubbing while applying makeup. It also advises waiting two hours before strenuous physical activity. Your clinician may give different or additional directions based on the product and treatment plan; follow those individualized instructions.
Do not use a social-media routine as a substitute for written aftercare. Ask before massaging the area, taking a new medicine for discomfort, applying an active skin-care product, or scheduling another facial procedure. Do not stop a prescribed medicine unless the clinician who manages it tells you to do so.
When should you contact the treating clinician?
Contact the treating clinician if a reaction is worsening, persistent, unexpected, or concerning to you. Examples include increasing swelling or pain, a new facial asymmetry, difficulty closing an eye, signs of infection, or another change that was not covered in the instructions you received.
The clinician who examined and treated you is best positioned to decide whether observation, an office evaluation, or urgent care is appropriate.
Which symptoms need immediate medical attention?
FDA-approved botulinum toxin products carry a boxed warning about possible spread of toxin effects beyond the injection area. Problems swallowing, speaking, or breathing can be life-threatening. The prescribing information also warns about symptoms such as generalized muscle weakness, double or blurred vision, drooping eyelids, or loss of bladder control.
Seek immediate medical attention for trouble breathing, swallowing, or speaking, or for another severe or rapidly developing symptom. Do not wait for a routine follow-up appointment.
Do not compare your timeline with someone else's
The onset, appearance, and duration of an effect vary with the specific product, dose, treatment area, anatomy, and individual response. A clinician should tell you when to assess the result and when, if ever, another treatment should be considered. More product or more frequent treatment is not automatically better.
Prepare before the next appointment
Keep the name of the product, the treatment date, and the clinician's contact information. Before another injection, disclose prior reactions and all medicines and supplements. If another clinician treated you recently with any botulinum toxin product, share the product and date.
