Track Your Side Effects

Note Your Observations

It is really important to keep track of your health symptoms, right from the time you start a new medicine. You can do it any way you prefer: in a notebook, in a computer file or using our online tool. You should also note down any other medicines you are taking at the same time, because there could be an interaction between these medicines.

Why Your Notes are Important

Your notes could be helpful in several ways:

  • You can use them to remind you of details that may alert your health care professional(s) to a problem
  • You will have a record to refer to in the future, in case you are ever prescribed the same medicine again

  • Log Form

    You can use the following log form to write down important information, like the date and time you experienced a side effect and your symptoms, how strong the symptoms were, and any other medicines you were using.

    Medicine Name and Dosage:
    Side Effects Scale Date & Time Other Medicine(s) or Treatment(s)
    Scale: 1 = very mild to 10 = very bad

    Side effects reports are analyzed to discover potential health product safety signals. Some important reactions may take an extremely long time to develop or occur infrequently. Continued monitoring of adverse reactions is thus essential to maintain a comprehensive safety and effectiveness profile of health products.

    You are encouraged to report negative side effects of prescription drugs to the FDA. Visit the FDA MedWatch website or call 1-800-FDA-1088.

    Calblock reports list potential signals of serious risks and new safety information that were identified using the FDA Adverse Event Reporting System (FAERS).
    FAERS is a database that contains information on adverse event and medication errors reports submitted to FDA by healthcare professionals (such as physicians, pharmacists, nurses and others), consumers (such as patients, family members, layers and others) and manufacturers.
