What Are Warnings and Precautions for Ranibizumab intravitreal injection?

Contraindications

  • Hypersensitivity
  • Ocular/periocular infections

Effects of drug abuse

  • None

Short-Term Effects

  • See “What Are Side Effects Associated with Using Ranibizumab intravitreal injection?”

Long-Term Effects

  • See “What Are Side Effects Associated with Using Ranibizumab intravitreal injection?”

Cautions

  • Hypersensitivity reactions may manifest as severe intraocular inflammation
  • Risk of endophthalmitis or retinal detachment with intravitreous injections; proper aseptic injection technique should always be used when administering therapy; patients should be monitored following the injection to permit early treatment should an infection occur
  • Possibility of IOP increase within 60 min of intravitreal injection; monitor intraocular pressure before and following intravitreal injection with drug and manage appropriately
  • Potential for adverse thromboembolic events (eg, nonfatal stroke, nonfatal MI, vascular death)
  • Temporary visual disturbances may occur
  • Fatal events occurred more frequently in patients with diabetic macular edema and diabetic retinopathy at baseline, who were treated monthly compared with control
  • No studies on the effects of ranibizumab on fertility conducted; not known whether ranibizumab can affect reproduction capacity; based on the anti-VEGF mechanism of action for ranibizumab, therapy may pose risk to reproductive capacity

Pregnancy and Lactation

  • There are no adequate and well-controlled studies in pregnant women
  • Administration of ranibizumab to pregnant monkeys throughout the period of organogenesis resulted in a low incidence of skeletal abnormalities at intravitreal doses 13-times the predicted human exposure (based on maximal serum trough levels [Cmax]) after a single eye treatment at the recommended clinical dose
  • Ranibizumab should be given to a pregnant woman only if clearly needed
  • Lactation
    • There are no data available on the presence of ranibizumab in human milk; effects of ranibizumab on breastfed infants or effects of ranibizumab on milk production/excretion; developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for therapy and any potential adverse effects on the breastfed child from ranibizumab
