Why People Take Ivermectin Without a Diagnosis

Some people opt for ivermectin because they think that they are infected with a parasite. Some people get their facts from social media, their friends, or the internet, rather than from any medical professional. However, some symptoms associated with a parasitic infection can also be related to other illnesses.

Common Reasons for Self-Treatment

  • Unexplained itching
  • Indigestion
  • Feeling tired
  • Irritation of the skin
  • Contact with someone who has parasites
  • Recommendations by non-medical experts

If one doesn’t have the right tests done, it will be hard to determine if ivermectin is suitable.

What Happens If You Take Ivermectin Unnecessarily?
