There are many circumstances in which an individual has to take more than one medicine, or has to take a drug with herbals, non-traditional medicine, substances of abuse, etc.. Sometimes they can be temporary situations, such as the need to treat an infective episode in addition to the treatment of chronic conditions. Other times, as it occurs in the older people, there are multiple chronic conditions that require concomitant treatment.

Concern about how the drugs act together in our body is legitimate. Also, according to some U.S. surveys, it is the most frequent concern of those who cross the threshold of a doctor’s office.

In order to make correct assessments, the doctor and the pharmacist should be fully informed about everything we take (and everything we have taken in recent weeks), also about the products that appear “devoid of significance” to us, as they are “natural”. Our body considers any substance that we introduce in the same way: as a “foreign substance”.

Even the foods are not exempt from this consideration. Some, such as grapefruit, are famous for the problems they can cause interacting with the medications. Others, certainly less important, can become problematic if taken in excessive quantities.

Cigarette smoking is another example of introduction of foreign substances that may decrease the effectiveness of many drugs.

Interactions Explorer is intended as a tool devoted to the professionals. Direct use by patients is not recommended, except incase of using it to discuss with your doctor or pharmacist, as after reading an information in a magazine or on the Internet.
