Why does gardasil cause fainting

Injections in general are known to be linked with fainting, and so this result "is not unexpected," the researchers said. There is evidence to suggest some of the skin infections seen in the study were actually reactions at the injection site, but the researchers did not have enough information to confirm this.

Unlike some earlier studies, the new study did not find an increased risk of blood clots linked with the vaccine. The researchers made sure to rule out side effects that were due to conditions the patients already had. Ongoing studies of HPV are still needed to examine the risk of side effects, the researchers said. However, there is not yet a definite answer about whether an ingredient of the vaccines is responsible for the fainting or if adolescents are simply more likely than children or adults to experience fainting.

Because fainting usually has no lasting effects, it is hard to study using medical records-based systems. However, because syncope may not always be reported, VAERS data cannot be used to determine how often fainting happens after vaccination. Fainting itself is generally not serious, but harm from related falls or other accidents can cause injury. The main concern is head injury.

Although fainting itself might or might not be preventable, it is important to prevent injuries when people do faint. Giving patients a beverage, a snack, or some reassurance about the procedure has been shown to prevent some fainting.

Studies are being done to look more into these strategies. However, many falls due to fainting can be prevented by having the patient sit or lie down. Fainting itself is generally not associated with serious outcomes, but can cause serious harm from related falls or other accidents. There is at least one report of a fatal case of fainting-related head injury after vaccination in the published literature. Falls that occur due to fainting after vaccination can be prevented by assuring that the vaccinated person is sitting in a chair or lying down and is observed for 15 minutes following vaccination.

Observe your patient and evaluate them after they regain consciousness to determine if there is a need for further treatment. If fainting occurs outside the medical setting and the person does not recover immediately, contact your local emergency medical services. Pre-marketing studies showed more reports of pain from Gardasil than from dummy shots, and patients reported more pain when given shots with more of the particles.

Meanwhile, U. From there were about 50 reports of fainting; from until last July, there were about About of those cases followed a shot of Gardasil, which came on the market in Barbara Slade, an immunization safety specialist at the U.
