Which are common contraindications or precautions for BoNT-A injections?

• A. Infection at the injection site, known hypersensitivity to BoNT-A components, pregnancy considerations in some cases, and precautions in patients with neuromuscular junction disorders.
• B. History of stroke within the past year.
• C. All patients regardless of condition can receive BoNT-A injections.
• D. There are no precautions needed for BoNT-A injections.

Answer: (A)

BoNT-A injections require careful consideration of factors that could increase risk or reduce safety. The most important points to know are that an infection at the injection site, a known hypersensitivity to BoNT-A or its components, pregnancy considerations in some cases, and precautions in patients with neuromuscular junction disorders all represent common contraindications or precautions. Infection at the injection site means the area isn’t ready for a needle poke and could spread or worsen, so treatment should be delayed until it heals. A known hypersensitivity to BoNT-A or its stabilizers poses a real allergy risk, so injections are avoided to prevent serious reactions. Pregnancy considerations reflect limited data on safety for a fetus; in many cases clinicians weigh potential benefits against unknown risks and may choose to postpone, especially when alternatives exist. Precautions in neuromuscular junction disorders, such as myasthenia gravis or Lambert-Eaton syndrome, are important because BoNT-A further impairs transmission at the neuromuscular junction and can worsen weakness. Options that claim a stroke history within the past year is a blanket contraindication are not accurate—BoNT-A can be used in many patients post-stroke with careful assessment. Saying all patients can receive injections or that no precautions are needed ignores these real safety factors.
