Hello there, Tynelol is paracetamol. The only pain killer preferred in pregnancy is paracetamol. Others should be avoided. So if you took tynelol then its no problem. Although paracetamol readily crosses the placenta, at recommended doses it does not appear to increase the risk of birth defects or other adverse outcomes of pregnancy. Taking more than the recommended dose of paracetamol may cause harm to the mother or baby s lives or kidneys. So taking paracetamol occasionally for painkiller in adequate doses is fine. Inacse of severe backache, you can apply voveron gel over the back. Local application wont harm you in anyway.
