32,660 males aged 70 (±5) who take Metformin are studied.


Number of reports submitted per year:

Metformin for a 70-year old man.

Information of the patient in this study:

  • Age: 70
  • Gender: male
  • Conditions: Diabetes
  • Drugs taken:
    • Metformin (metformin hydrochloride)

eHealthMe real world results:

Comparison with this patient's adverse outcomes:

  • Rash Macular(small, flat red spots): 45 (0.14% of males aged 70 (±5) who take the drug)

As an adverse outcome could be a symptom of a condition, additional studies are listed to help identify the cause: for example, regardless of which drug is taken, how many female HBP patients aged 50 (±5) have nausea

As an adverse outcome could be a side effect of a drug, additional studies are listed to help identify the cause: for example, how many female Aspirin users aged 50 (±5) have nausea
