Can You Have Botox When Pregnant or Breastfeeding? Guidance for Elective Treatment

Clinical guidance from Dr Nyla Raja MBChB (Hons), MRCGP (Dist), DFFP, DPDermatology - GMC No. 6057913

For cosmetic Botox, the cautious answer is usually no: elective treatment is generally deferred during pregnancy and while breastfeeding. The UK product information for BOTOX does not recommend use in pregnancy, and states that use during breast-feeding cannot be recommended.

This does not mean that an injection received before a pregnancy was recognised is known to cause harm. It means that the available evidence is not strong enough to establish routine safety, and an aesthetic treatment can normally wait. At Dr Nyla Medispa, Botox treatment is prescribed only after a medical assessment, including discussion of pregnancy, breastfeeding, current health, and medicines.

Why elective Botox is postponed in pregnancy

Botox is a prescription-only medicine containing botulinum toxin type A. In aesthetic treatment, carefully selected muscles are relaxed to soften dynamic lines, such as frown lines, forehead lines, and crow’s feet. Although the treatment is placed locally, it is still a medicine with specific prescribing information.

There are no adequate studies of BOTOX in pregnant women. The UK Summary of Product Characteristics notes reproductive toxicity in animal studies, while the potential risk in human pregnancy remains unknown. It therefore advises against use during pregnancy, including in women of childbearing potential who are not using contraception.

Some published pregnancy reports have not identified a clear pattern of adverse outcomes following exposure to onabotulinumtoxinA. However, these data are observational, may be affected by incomplete reporting, and cannot reliably exclude uncommon or delayed risks. A recent systematic review similarly concluded that the evidence remains insufficient to establish safety in pregnancy. Read the systematic review on PubMed.

For this reason, the decision is not based on proving that cosmetic Botox is harmful. It is based on the absence of reassuring, high-quality evidence needed to justify a non-urgent treatment during pregnancy. The UK Teratology Information Service advises that botulinum toxin type A in pregnancy should usually be reserved for therapeutic situations where there is no suitable alternative, and that cosmetic use should be avoided. Read the UKTIS guidance on botulinum toxin exposure in pregnancy.

Can you have Botox while breastfeeding?

For elective aesthetic treatment, it is generally sensible to wait until breastfeeding has finished. The UK product information states that it is not known whether BOTOX passes into human milk and that its use during breast-feeding cannot be recommended.

The evidence is evolving, but remains limited. Small studies of cosmetic-dose onabotulinumtoxinA have found either no detectable toxin or very small amounts in milk samples, and there is not enough information about higher doses, different botulinum toxin products, or longer-term infant outcomes. The LactMed database notes that the available studies relate only to onabotulinumtoxinA at cosmetic doses.

That distinction matters. A small amount of encouraging evidence does not override the licensed product advice, nor does it make aesthetic treatment necessary during breastfeeding. It is also not a reason to make changes to feeding, express milk, or stop breastfeeding without discussing the specific situation with an appropriate clinician.

Medical botulinum toxin treatment is a different decision

Botulinum toxin is used medically for conditions including chronic migraine, muscle spasticity, excessive sweating, bladder conditions, and certain movement disorders. These treatments may involve different doses, injection sites, products, and potential benefits from cosmetic treatment.

If you are pregnant or breastfeeding and receive botulinum toxin for a diagnosed medical condition, do not independently stop or delay treatment. Your specialist, GP, neurologist, maternity team, or other prescribing clinician should consider the reason for treatment, the severity of symptoms, alternatives, the product involved, and the potential effect of changing your care plan.

Likewise, Botox is a brand name, not a catch-all term for every botulinum toxin product. Products are not interchangeable, and each has its own licensed information. A decision about one product should not be applied automatically to another.

If you had Botox before you knew you were pregnant

Finding out that you were pregnant after a recent aesthetic appointment can be worrying, but it is not usually a reason to assume that a problem will occur. UKTIS notes that the limited human data do not raise concern about adverse pregnancy outcomes, while also recognising that they are too limited to rule out a risk completely.

• Tell your midwife, GP, obstetric team, or the clinician providing your pregnancy care.
• If possible, keep a record of the product used, treatment date, dose, and injection areas.
• Contact the practitioner who treated you if you need this information.
• Do not arrange further elective botulinum toxin treatment during pregnancy without clinical advice.

Individual advice is particularly important if treatment was for a medical condition, involved a higher dose, or if you have any new symptoms following the injection.

What to discuss before a future Botox appointment

If you are trying to conceive, think you may be pregnant, are pregnant, or are breastfeeding, mention this before any prescribing or treatment appointment. A medical consultation should also cover previous botulinum toxin treatment, medicines and supplements, neurological or muscular conditions, and any prior adverse reactions.

The key point

Cosmetic Botox is best postponed during pregnancy and breastfeeding. The decision reflects limited safety evidence and current UK product advice, not a need for alarm if treatment happened before you knew you were pregnant. Where botulinum toxin is being considered for a medical condition, the potential benefit and alternatives should be assessed individually by the clinician responsible for that care.
