Tripedia Side Effects

Although most children do not experience any problems after receiving the Tripedia vaccination, adverse reactions are possible. Drowsiness, irritability, and redness at the injection site are the most common problems that have been reported with this vaccine. Some of the rare but serious side effects of Tripedia include paralysis, high fever, and seizures.

An Introduction to Tripedia Side Effects

As with all vaccines, side effects are possible with Tripedia^® (DTaP). However, not everyone who receives the vaccine will have problems. In fact, most children tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can be treated easily by you or your healthcare provider.

(This article covers many, but not all, of the possible side effects with Tripedia. Your healthcare provider can discuss a more complete list with you.)

Common Side Effects of Tripedia

Tripedia has been studied thoroughly in clinical trials. In these studies, the most common Tripedia side effects included:

Drowsiness -- in up to 41.5 percent of children
Irritability -- up to 35.3 percent
Redness at the injection site -- up to 59.8 percent
Pain at the injection site -- up to 21.4 percent
Swelling at the injection site -- up to 61.4 percent
Loss of appetite -- up to 22.2 percent
Vomiting -- up to 7.4 percent
Fever -- up to 25 percent
High-pitched cry -- up to 2.4 percent.

As with other DTaP vaccines, skin reactions (such as pain, redness, and swelling) at the injection site generally become more frequent as more doses are given. In other words, a child is less likely to have a skin reaction with the first doses of the vaccine, but is more likely to have a skin reaction with the more doses he or she receives.
