Unlike other cancer medicines—like PERJETA® (pertuzumab) or Herceptin® (trastuzumab), which are given by infusion through an IV or port—PHESGO is given by injection, sort of like a “shot.”
Since it’s an injection under the skin, PHESGO does not require port access.
PHESGO is always given by a healthcare professional.
PHESGO is administered by slowly injecting it just under the skin of the thigh. At each appointment, the injection alternates between the left and right thigh.
The first dose of PHESGO takes about 8 minutes to inject. Other doses take about 5 minutes to inject.
Your healthcare team will wait at least 30 minutes after the first dose, and at least 15 minutes after each following dose, to check for any reactions. If side effects occur, your healthcare provider may slow, delay, or stop your treatment.
Depending on your condition, your healthcare team will determine the treatment plan that’s right for you. You can also explore what your treatment schedule might look like here:
If you miss a dose of PHESGO, DO NOT WAIT until your next treatment. Contact your doctor or nurse right away and work with them to reschedule the treatment you missed.
Wear loose shorts or a skirt for your appointment so your healthcare provider can easily access your thigh for the injection. It’s a good idea to bring a blanket, too, to stay warm.
During injection, you’ll have at least 5 minutes of undivided time with your healthcare provider, so it’s a good idea to come prepared with questions to ask about your treatment and progress. You can also talk about how you’re feeling and about any side effects you may be experiencing.
Call the Patient Resource Center for answers to your questions about PHESGO or other resources from Genentech.
