However, you may experience insulin side effects such as injection site reactions, with symptoms such as redness, irritation or pain. If this happens, you should stop taking the medication and inform your doctor immediately. Although rare, you may experience allergic reactions when you use insulin medication.

Symptoms of allergic reactions include

  • difficulty breathing
  • severe dizziness
  • rash
  • swelling in the tongue, throat and face
  • skin rash

If you notice any of these symptoms, you should seek medical help immediately. Taking insulin medication can also lead to hypoglycemia or low blood sugar levels. This may occur if you do not get enough calories from food or you exercise too heavily.

Symptoms of hypoglycemia include

  • fast heartbeat
  • dizziness
  • shaking
  • blurred vision
  • hunger
  • sweating
  • tingling feeling in feet or hands

It is important you carry glucose gel or tablets to treat symptoms of hypoglycemia. You can treat low blood sugar levels by taking fast acting carbohydrates such as hard candy, honey, table sugar or non diet soda.
