What to Expect with SOMAVERT


The goal of SOMAVERT treatment is to help you reach a normal IGF-I level and to provide relief of disease symptoms. Remember that “a normal level” is mostly defined by age. Talk to your doctor about what level is right for you.

In 2 clinical trials, the majority of patients treated with SOMAVERT achieved normal IGF-I levels for their age.

  • In a long-term study, 92% of patients treated with SOMAVERT achieved normal IGF-I levels at 55 weeks.
    • This data comes from a part of a study involving 38 of the original 160 patients who received SOMAVERT. Their dose of SOMAVERT was changed until their IGF-I levels were normal.
  • In a short-term study, 82% of patients treated with 20 milligrams (mg) daily of SOMAVERT achieved normal IGF-I levels at 12 weeks.*
    • In this same study, the overall signs and symptoms of acromegaly improved in patients who took SOMAVERT compared with those who took a placebo.
      • This study showed how patients rated the change in their symptoms, which included joint pain, headaches, fatigue, sweating, and soft tissue swelling.

* This data is from a clinical trial that involved 112 patients with acromegaly. 31 patients received a placebo. 80 were treated with SOMAVERT at one of three doses. Results for patients achieving normal IGF-I levels for their age were: 10% of patients taking a placebo; 39% of those on 10 mg per day of SOMAVERT; 75% of those on 15 mg per day of SOMAVERT; 82% of those on 20 mg per day of SOMAVERT.

SOMAVERT has been shown to reduce the signs and symptoms of acromegaly and normalize IGF-I levels. Your doctor will determine the dose that is right for you. Be sure to take SOMAVERT exactly as directed by your doctor. Your test results are used to see if that dose is best. And remember, studies have shown that an increase in dosage does not seem to cause an increase in side effects.

Your SOMAVERT Starter Kit

As you begin treatment, your starter kit includes several tools that you may find helpful


SOMAVERT (pegvisomant for injection) is a prescription medicine for acromegaly. It is for patients whose disease has not been controlled by surgery, radiation, and/or other medical therapies, or patients for whom these options are not appropriate. The goal of treatment with SOMAVERT is to have a normal IGF-I level in the blood.

Important Safety Information for Patients

Do not use SOMAVERT if you are allergic to SOMAVERT or anything that is in it.

Be sure to tell your doctor if you use narcotic painkillers (opioid medicines) because the dose of SOMAVERT may need to be changed.

Tumors that make growth hormone may grow in people with acromegaly. Studies have shown that the size of these tumors generally does not change for people who use SOMAVERT. Even so, these tumors need to be watched carefully by your doctor. Your doctor may ask you to have a magnetic resonance imaging (MRI) test to monitor the size of your tumor.

Blood sugar levels may go down when taking SOMAVERT. Be sure to tell your doctor if you use insulin or other medicines (oral hypoglycemic medicines) for diabetes. The dose of these medicines may need to be reduced when you use SOMAVERT.

Some people who have used SOMAVERT have developed liver problems. These problems generally disappeared when those people stopped taking SOMAVERT.

Stop the drug right away and call your doctor if you get any of these symptoms:

  • Your skin or the white part of your eyes turns yellow (jaundice)
  • Your urine turns dark
  • Your bowel movements (stools) turn light in color
  • You do not feel like eating for several days
  • You feel sick to your stomach (nausea)
  • You have unexplained tiredness
  • You have pain in the stomach area (abdomen)

Your doctor may do blood tests before and during your treatment with SOMAVERT to check that the IGF-I levels in your blood are normal and/or that your liver is working correctly. Your dose of SOMAVERT may be changed based on the results of these tests.

The most common side effects with SOMAVERT are pain, infection, reaction at the injection site, flu-like symptoms, nausea, and diarrhea. These are not all of the possible side effects of SOMAVERT. For more information, speak to your doctor.

Inject SOMAVERT in a different place on your body each day. This can help prevent skin problems such as lumpiness or soreness.

SOMAVERT has not been studied in pregnant women. It is not known if SOMAVERT passes into the mother’s milk or if it can harm the baby.
