This medication falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.

- The first injection will last 90 minutes.
- If the first injection is received with no serious side effects, the second injection will be given over 60 minutes.
- If the infusion over 60 minutes was tolerated, the next doses will be given over 30 minutes.
Your doctor will determine how much Avastin you will receive and how often you will receive it based on your weight and the condition being treated.

Avastin FDA Warning
Avastin administration can result in the development of gastrointestinal perforation, in some instances resulting in fatality.
- Gastrointestinal perforation, sometimes associated with intra-abdominal abscess, occurred throughout treatment with Avastin (i.e., was not correlated to duration of exposure).
- The incidence of gastrointestinal perforation (gastrointestinal perforation, fistula formation, and/or intra-abdominal abscess) in patients with colorectal cancer and in patients with non-small cell lung cancer (NSCLC) receiving Avastin was 2.4% and 0.9%, respectively. The typical presentation was reported as abdominal pain associated with symptoms such as constipation and vomiting.
- Gastrointestinal perforation should be included in the differential diagnosis of patients presenting with abdominal pain on Avastin.
- Avastin therapy should be permanently discontinued in patients with gastrointestinal perforation.
Wound Healing Complications
- Avastin administration can result in the development of wound dehiscence, in some instances resulting in fatality.
- Avastin therapy should be permanently discontinued in patients with wound dehiscence requiring medical intervention.
- The appropriate interval between termination of Avastin and subsequent elective surgery required to avoid the risks of impaired wound healing/wound dehiscence has not been determined.
- Fatal pulmonary hemorrhage can occur in patients with non-small cell lung cancer treated with chemotherapy and Avastin.
- Incidence: The incidence of serious or fatal hemoptysis was 31% in patients with squamous histology and 2.3% in patients with NSCLS excluding predominant squamous histology.
- Patients with recent hemoptysis (at least one-half teaspoonful of red blood) should not receive Avastin.
