Macular Degeneration Home > Lucentis Warnings and Precautions

Before starting treatment, make sure you understand the Lucentis warnings and precautions that apply to you. For example, your healthcare provider should monitor the pressure in your eye after each injection, and you should avoid the medication if you have an infection in or around your eyes. Lucentis warnings and precautions also include understanding that it may increase your risk of blood clots or strokes and cause retinal detachment.

Lucentis: What Should I Tell My Healthcare Provider?

You should talk with your healthcare provider prior to taking Lucentis® (ranibizumab) if you have:
  • An infection in or around the eyes
  • Had a blood clot or stroke
  • Any allergies, including allergies to food, dyes, or preservatives.
Also, let your healthcare provider know if you are:
  • Pregnant or thinking of becoming pregnant
  • Breastfeeding.
Make sure to tell your healthcare provider about all medicines you are taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.

Specific Lucentis Warnings and Precautions

Warnings and precautions to be aware of prior to taking Lucentis include the following:
  • As with any injection into the eye, Lucentis can cause retinal detachment or other eye problems (although this is rare). Retinal detachment is very serious and can lead to blindness.
  • Sometimes, Lucentis injections can cause a temporary increase in the pressure inside the eye. Your healthcare provider should monitor your eyes immediately after each injection to make sure that the pressure in your eye is not too high.
  • Theoretically, Lucentis could increase the risk of blood clots or strokes. Talk with your healthcare about this risk, especially if you have a history of blood clots or stroke.
  • Lucentis is unlikely to interact with other medications (see Lucentis Drug Interactions).
  • Lucentis is considered a pregnancy Category C medication. This means that it may not be safe for use during pregnancy, although the full risks are not known. Talk to your healthcare provider about the risks and benefits of using the drug while pregnant (see Lucentis and Pregnancy).
  • It is not known if Lucentis passes through breast milk. Therefore, if you are breastfeeding or plan to start, discuss this with your healthcare provider prior to taking the drug (see Lucentis and Breastfeeding).
