Talk to your doctor about any medicine that takes. Be sure to say to all those who prescribed medicines that you are pregnant. Even drugs that are asquieren without a prescription can harm a baby, especially if taken during the first months of pregnancy since all organs are being formed.
If you are taking any drug during pregnancy, we must take into account the following premises:
• Try not to consume any drug during the first trimester unless it is essential.
• Avoid self-medication.
• Consider the risk/benefit ratio and the minimum effective dose.
• Do not consider no safe drug for baby in 100%.
• Use those drugs that you have more experience in pregnant women.
• Keep in mind that the topical medication also absorbs, (E.g., creams)
Of course that there are large number of studies on the safety of numerous drugs during pregnancy and in what circumstances the risk of using them would overcomethe benefits that may arise.
Analyzing and group all of these studies have allowed different classifications ofmedications according to the risk to the fetus. One of the most widespread is the onemade by the American FDA, which is responsible for the authorization andmonitoring of medicines in the United States.
This classification includes medication in 5 categories:Classification of drugs for use during pregnancy:
• Category A: women-controlled studies do not demonstrate a risk to the fetus in thefirst trimester and there is no obvious risk in the rest of the pregnancy. The possibilityof fetal injury seems remote.
• Category B: animal reproduction studies do not indicate any risk to the fetus, butthere are no controlled studies on pregnant women; or animal reproduction studieshave shown adverse effects which are not confirmed in controlled studies in the firstquarter.
• Category C: animal studies have shown adverse effects on the fetus and there are nocontrolled studies in women; or not there are studies on women and animals. Drugsof this group should be given only if the potential benefit justifies the potential risk tothe fetus.
• Category D: there is positive evidence of risk to the human fetus.
• Category X: studies in animals and humans have demonstrated fetal abnormalitiesor there is evidence of fetal risk based on human experience and/or animals. The riskof its use in pregnant women clearly exceed any benefits and they arecontraindicated in women who are or may be pregnant.
