Paracetamol Pregnancy Risks: Women often have fears and questions about medications during pregnancy. Especially when it comes to pain or fever, it can be difficult to determine whether the medication is appropriate. Recently, rumors have spread that taking paracetamol (called Tylenol in the US) during pregnancy can increase the risk of autism in the child. This claim caused concern worldwide, but now a large and reliable study has clarified this.
According to a major research study published in the medical journal The Lancet Obstetrics, Gynaecology & Women's Health, no direct link was found between proper paracetamol use during pregnancy and the risk of autism, ADHD, or mental development in children. Let's explore what else the study revealed.
What does the new study say?
This major study analyzed 43 different clinical studies. It also included data from approximately 2.5 million children in Sweden. The researchers specifically used a sibling comparison method, comparing children of the same mother who took paracetamol during one pregnancy and not the other. The results were clear: there was no difference in the risk of autism or other mental health problems between the two children.
Does taking paracetamol during pregnancy cause autism in the child?
Some earlier studies had shown a slight link with taking paracetamol during pregnancy, but scientists now say this wasn't the real cause. In fact, women who took paracetamol were more likely to have problems like fever, pain, or infection. These problems themselves can affect a child's development. Genetic factors also play a role. These confounding factors led to earlier incorrect conclusions, which led people to believe that taking paracetamol during pregnancy caused autism in children.
What do experts say?
According to experts, paracetamol is still considered the safest pain reliever during pregnancy. It is safer than NSAIDs and opioids. It is best taken in small doses and only when needed. It is also included in the World Health Organization (WHO) list of essential medicines.
When can not taking this medicine be dangerous?
Sometimes, fear makes women avoid taking medication, but this can be extremely dangerous. Untreated fever or pain during pregnancy can lead to miscarriage, premature delivery, or birth defects in the baby. Therefore, it is crucial to seek treatment according to your doctor's advice.
What is right for women during pregnancy?
1. Take paracetamol only when it is really needed.
2. Always follow the doctor's advice before and during taking the medicine.
3. Do not take medicine in larger quantities or for a longer period than you wish.
4. Do not ignore fever or pain, get timely treatment.
