If you or someone in your family has experienced a serious side effect to a health product, you are encouraged to report the experience to your health care professional (e.g. physician, pharmacist). You could also complete a copy of the side effect reporting form or report your side effect to FDA.

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.

Alfarol Side Effects Reported to FDA

The following Alfarol 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.


The appearance of Alfarol on this list does not mean that FDA has concluded that the drug has the listed risk. It means that FDA has identified a potential safety issue, but it does not mean that FDA has found a causal relationship between the drug and the listed risk.
Rash
This is a report of a 68-year-old male patient (weight: NA) from JAPAN, suffering from the following symptoms/conditions: NA, who was treated with Alfarol (dosage: NA, start time: Apr 18, 2012), combined with:
  • Nateglinide
  • Rebetol
  • Peginterferon Alfa-2b
  • Locholest
  • Telavic (telaprevir)
and developed a serious reaction and side effect(s). The consumer presented with:
  • Rash
which developed after the beginning of treatment. This case can indicate the possible existence of increased vulnerability to Alfarol treatment in male patients, resulting in rash side effect.

Liver Disorder, Haemosiderosis, Hepatitis, Fatigue, Periportal Oedema
This report suggests a potential Alfarol Liver Disorder, Haemosiderosis, Hepatitis, Fatigue, Periportal Oedema side effect(s) that can have serious consequences. A female patient (weight: NA) from JAPAN was diagnosed with the following symptoms/conditions: NA and used Alfarol (dosage: 0.5 Ug, Unk) starting Feb 13, 2009. Soon after starting Alfarol the patient began experiencing various side effects, including:
  • Liver Disorder
  • Haemosiderosis
  • Hepatitis
  • Fatigue
  • Periportal Oedema
Drugs used concurrently:
  • Exjade (1000 Mg, Daily)
  • Fosamax (5 Mg, Unk)
  • Pravastatin Sodium (10 Mg, Unk)
  • Exjade (1000 Mg, Daily)
  • Calblock (16 Mg, Unk)

Keep Track of Side Effects

Note Your Observations

It is really important to keep of your 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

    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.
