Effects of Pegaptanib

Two studies have evaluated pegaptanib for the treatment of wet macular degeneration. These studies compared pegaptanib injections to "placebo" injections (which contained no active ingredient). These studies showed that the medication slowed down vision loss, especially during the first year of treatment. During the second year of treatment, pegaptanib continued to slow down the rate of vision loss, although it was less effective than during the first year.

When and How to Take It

General considerations to keep in mind during treatment include the following:
  • Pegaptanib is injected into the eye every six weeks by your healthcare provider.
  • Your eye(s) will be numbed before the injection. While you should feel no pain, you may feel a little pressure.
  • For the medication to work properly, it must be used as prescribed. Pegaptanib will not work if you stop taking it.

Dosage Information for Pegaptanib

The dosage that your healthcare provider recommends will vary, depending on a number of factors, including:
  • How you respond to pegaptanib
  • Other medications you may be taking
  • Other medical conditions you may have.
As is always the case, do not adjust your dose unless your healthcare provider specifically tells you to do so.
