From the FDA Drug Label

Dry eye has been reported with the use of botulinum toxin products in the treatment of glabellar lines. Reduced tear production, reduced blinking, and corneal disorders may occur with use of botulinum toxins, including JEUVEAU. If symptoms of dry eye (e.g., eye irritation, photophobia, or visual changes) persist, consider referring patients to an ophthalmologist

There is a known connection between botulism injections, such as botulinum toxin (IM), and dry eyes. The drug label warns of ophthalmic adverse reactions, including dry eye, which can occur due to reduced tear production, reduced blinking, and corneal disorders. However, there is no direct information in the provided drug label about the connection between botulism injections for migraine and dry eyes. The label does mention the use of botulinum toxin products for the treatment of glabellar lines, but it does not explicitly address the treatment of migraine 1.

From the Research

Yes, there is a known connection between botulinum toxin (Botox) injections for migraines and dry eyes, as botulinum toxin can affect the nerves that control tear production or blinking frequency. According to a study published in The British journal of ophthalmology 2, botulinum toxin A injections can improve photophobia and dry eye symptoms in patients with chronic migraine, independent of baseline tear film volume. The study found that photophobia scores significantly improved following botulinum toxin A injections, while dry eye symptoms significantly improved in those with severe symptoms at baseline. This suggests that botulinum toxin A injections may be beneficial for patients with chronic migraine who also experience dry eye symptoms. It's essential to discuss any eye-related side effects with your healthcare provider, as they may adjust the injection sites or dosage in future treatments to minimize this side effect while maintaining migraine control. Additionally, a study published in the Oman journal of ophthalmology 3 found that botulinum neurotoxin type A injections can be a good alternative to punctal plugs in improving the clinical manifestations of dry eye disease, with fewer and milder complications and higher levels of patient satisfaction. However, it's crucial to weigh the benefits and risks of botulinum toxin injections for migraines and dry eyes, considering the individual patient's needs and medical history. In general, the dry eye symptoms caused by botulinum toxin injections are typically temporary and resolve as the Botox effect wears off over 2-3 months. If you're experiencing dry eyes after Botox treatment for migraines, you can use artificial tears for relief. Some key points to consider include:

  • Botulinum toxin A injections can improve photophobia and dry eye symptoms in patients with chronic migraine.
  • The improvements in dry eye symptoms are independent of baseline tear film volume.
  • Botulinum neurotoxin type A injections can be a good alternative to punctal plugs in improving the clinical manifestations of dry eye disease.
  • The dry eye symptoms caused by botulinum toxin injections are typically temporary and resolve as the Botox effect wears off over 2-3 months.
  • It's essential to discuss any eye-related side effects with your healthcare provider to adjust the injection sites or dosage in future treatments.
