Tdap is a class C drug: no adequate studies in humans

“The truth is that the Tdap shot has never been proven safe for use during pregnancy. In fact, Tdap is classified by the FDA as a Class C drug. The definition of a Class C drug which is how the Tdap shot is classified: ‘Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.’

Studies have shown that SSRIs (selective serotonin reuptake inhibitors) taken during pregnancy increase the risk of birth defects of the heart and lungs. Another study in the Netherlands found an association between preterm birth and delayed fetal head growth for those mothers taking anti-depressants.

More recently, a study out of CHE Ste-Justine’s Research Center in Canada, indicated SSRIs can increase blood pressure in the mother. High blood pressure during pregnancy is very dangerous and can lead to a serious and potentially deadly condition known as pre-eclampsia.

Class C drugs are clearly not a safe choice during pregnancy.”
