Lucentis is typically administered through an injection directly into the eye by a healthcare professional. The frequency of injections and duration of treatment will depend on the individual's specific condition and response to the medication. It's important to note that Lucentis injections are generally well-tolerated, but there are potential side effects to be aware of, including eye pain, redness, or swelling, as well as increased risk of infection or bleeding. It's important to discuss the risks and benefits of Lucentis treatment with your doctor if you are considering this medication.
