What is Gardasil 9?
Gardasil is used to prevent genital warts and cervical/vaginal/anal cancers caused by human papillomavirus (HPV) types 6, 11, 16, and 18 in girls and young women ages 9 through 26. Gardasil is also used to prevent genital warts caused by HPV types 6 and 11 in boys and young men ages 9 through 26. Human papillomavirus (HPV) can cause genital warts, cancer of the cervix, and various cancers of the vulva or vagina.
The quadrivalent form of HPV vaccine (Gardasil) is used in both females and males. Another form of HPV vaccine (Cervarix) is used only in females. This medication guide provides information only for Gardasil.
The Centers for Disease Control and Prevention (CDC) recommends HPV vaccine for all girls ages 11 or 12 years old. The vaccine is also recommended in girls and women ages 13 through 26 years old who have not already received the vaccine or have not completed all booster shots.
You may receive Gardasil even if you have already had genital warts, or had a positive HPV test or abnormal pap smear in the past. However, Gardasil will not treat active genital warts or HPV-related cancers, and it will not cure HPV infection.
Important information about Gardasil
You should not receive a booster Gardasil vaccine if you have had a life-threatening allergic reaction after the first shot.
Before receiving Gardasil, tell your doctor if you have a high fever or signs of infection, a weak immune system, a bleeding disorder such as hemophilia, or if you are taking a blood thinner such as warfarin (Coumadin).

Gardasil should not be used in place of having a routine pelvic exam and Pap smear to screen for cervical cancer. You may receive Gardasil even if you have already had genital warts, or had a positive HPV test or abnormal pap smear in the past. However, Gardasil will not treat active genital warts or HPV-related cancers, and it will not cure HPV infection. You may feel faint after receiving Gardasil. Some people have had seizure-like reactions after receiving this vaccine. Your doctor may want you to remain under observation during the first 15 minutes after the injection.
Developing cancer from HPV is much more dangerous to your health than receiving the vaccine to protect against it. However, like any medicine, Gardasil can cause side effects but the risk of serious side effects is extremely low.
Gardasil will not protect against sexually transmitted diseases such as chlamydia, gonorrhea, herpes, HIV, syphilis, and trichomoniasis.

How is Gardasil given?
Gardasil is given as an injection (shot) into a muscle in your upper arm or thigh. You will receive this injection in a doctor's office or other clinic setting.
Gardasil is given in a series of 3 shots. You may have the first shot at any time as long as you are between the ages of 9 and 26 years old. Then you will need to receive a second dose 2 months after your first shot, and a third dose 6 months after your first shot.
Be sure to receive all doses of Gardasil recommended by your healthcare provider or your state's health department. You may not be fully protected if you do not receive the full series.
Gardasil should not be used in place of having a routine pelvic exam and Pap smear to screen for cervical cancer.
What happens if I miss a dose?
Contact your doctor if you will miss an Gardasil booster dose or if you get behind schedule. The next dose should be given as soon as possible. There is no need to start over.
Be sure you receive all recommended doses of Gardasil. If you do not receive the full series of vaccines, you may not be fully protected against the disease.
What happens if I overdose?
An overdose of this vaccine is unlikely to occur.
What should I avoid while receiving Gardasil?
There may be certain other vaccines that should not be given at the same time as the Gardasil. Until you have completed the series of 3 Gardasils, do not receive any other vaccine (including a flu shot) without first asking your doctor.
