Gardasil is the human papillomavirus (HPV) vaccine that protects against four types of HPV strains. These include types 6 and 11, which commonly cause genital warts, and types 16 and 18, which are high risk and can lead to cervical cancer. Gardasil is recommended for girls and women between the ages of 9 and 26 for the prevention of these diseases, but it provides no use in treatment. Gardasil administration is associated with certain side effects.
Common Side Effects
Drowsiness or dizziness are common side effects of the Gardasil shot, affecting up to 4 percent of those who receive it. If you experience these symptoms, do not drive or perform any activity that requires alertness. Other common side effects of Gardasil include nausea, vomiting and diarrhea. To avoid nausea, which can occur in up to 7 percent of people, try chewing gum or sucking on hard candy. About 2 to 4 percent of people experience diarrhea and vomiting, but these may be avoided by eating small meals throughout the day.
Injection Site Reactions
Gardasil is administered in three doses each containing a 0.5 ml dose. The first dose is given on the day chosen, and the second dose is given two months later. The third dose is given six months after the first dose. The shot is given in the deltoid muscle of the upper arm or thigh muscle and sometimes causes injection-site reactions. Pain at the injection site is a typical side effect and is seen in 84 percent of individuals. In about 25 percent of people, swelling, redness, bruising and a rash may develop. If any of these symptoms become severe, contact your physician.
Fainting
Fainting is another side effect associated with Gardasil, particularly in preteens. Girls and women should be instructed to sit or lie down for 15 minutes after the administration of the vaccine to avoid falling and getting hurt.
Fever and Headache
Fever, which can occur in 10 to 13 percent of individuals, is another side effect of Gardasil. Signs of a fever after Gardasil administration do not indicate an infection and are not a cause of worry. Headache, which can occur alone or with a fever, is seen in about 28 percent of people.
