Why should not medicines be taken without consulting doctors ?

Text Solution

Verified by Experts

The drugs or medicines have side effects also. In addition to normal desired therapeutic effect, drugs may also cause other effects which may be beneficial or harmful. These side effects arise because the drug may bind to more than one type of receptor. Therefore, the doctor must be consulted to choose the right drug which has maximum affinity for a particular receptor site to have the desired effect. The doctor will also advise for the correct doses because some drugs like opiates in higher doses may act as poisons leading to serious problems and even may cause death.
