Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Blood clotting: Treatment with ranibizumab should be stopped for people who develop clots that block their blood vessels. Tell your doctor if you have a history of clotting or are over 65 years of age, as you may be at increased risk of experiencing blood clot-related problems such as heart attack, stroke, or clots in the deep veins of your leg. People with any of these conditions should discuss with their doctor, how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Driving and using machines: Ranibizumab may cause short term blurred vision, affecting your ability to drive or operate machinery. Avoid these and other hazardous tasks until your vision is clear.
Eye problems: Ranibizumab can cause eye problems such as infection of the inside part of the eye, pain or redness, detachment or tear of the retina, or clouding of the lens. If you experience eye pain, increased eye discomfort, worsening eye redness, blurred or reduced vision, increased sensitivity of the eyes to light, or an increase in the number of small particles in your vision, contact your doctor immediately.
Increased eye pressure: Ranibizumab can increase the pressure in the eye for a short period of time after it is injected. Your doctor will do tests to make sure the pressure in your eye is not elevated persistently after treatment.
Vision problems: Ranibizumab can cause temporary vision problems that may affect your ability to drive or operate machines. If you experience vision problems, do not drive or operate machines until your vision returns to normal.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If there is a chance that you may become pregnant while receiving this medication, talk to your doctor about whether you should use effective contraception during treatment. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if ranibizumab passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children and adolescents: The safety and effectiveness of using this medication have not been established for children and adolescents.
