Ivermectin is a prescription drug that has been approved by the US Food and Drug Administration (FDA) to treat a wide range of parasitic diseases(scabies) in humans. During the pandemic, a misconception about Ivermectin causing infertility in men rose significantly.

However, global health authorities have not recognized male infertility as a side effect of Ivermectin medication yet.

Ivermectin tablets (Ivecop) belong to a class of medication called anthelmintics. This medication works by interfering with parasitic worms’ nerve and muscle functions, paralyzing and killing them.

What are the side effects of Ivermectin?

Medicines can cause side effects if not correctly administered by a health care professional. It is essential to follow the doctor’s guidelines while taking Ivermectin 3mg tablets. Some of the common side effects that may result after taking Ivermectin are as follows:

  • Headache or dizziness
  • Nausea or vomiting
  • Increased tiredness
  • Change in vision
  • Shortness of breath
  • Pain in muscle or joints
  • Stomach pain or diarrhea
  • Rashes, itching, or swelling
  • Swollen lymph nodes

Consult your doctor at the earliest when such side effects do occur. Your doctor may change the dosage of Ivermectin or prescribe some other medication that can be more effective.

Can Ivermectin cause infertility?

During the pandemic’s peak, a lot of speculation arose about the effectiveness of the Ivermectin drug in treating Covid. A lot of misinformation about Ivermectin is available due to the use of social media channels.

Though public health authorities like World Health Organization(WHO) and FDA strictly warned against Ivermectin in treating coronavirus infection, many people still tried using the drug.

A study suggested that Ivermectin was responsible for male sterility during this time. Within a matter of time, the misinformation spread worldwide, resulting in more confusion.

The claims about Ivermectin causing male infertility were based on a Nigerian study done in 2011. The researchers studied the effects of Ivermectin on fertility in men with onchocerciasis, which is also known as river blindness. The study highlighted that Ivermectin causes infertility in almost 85% of men who take the medication.

However, questions were raised about the authenticity and reliability of the study. The Nigerian study was eventually problematic due to the following reasons:

  • The sample size was too small, consisting of only 37 people.
  • There was no mention of a peer review process.
  • There was no mention of any control group in the study.
  • The sample only consisted of men who had river blindness.

Therefore, medical professionals advised that one should not rely on the misinformation that is generally circulated during such uncertain times of the pandemic. One should mainly trust the information provided by public health authorities like FDA, WHO, and the Centers for Disease Control and Prevention (CDC).

What was the FDA’s response?

In response to the spread of false information about Ivermectin tablets causing infertility as a side effect, the US Food and Drug Administration responded by clearly stating the side effects of Ivermectin. 

Some of the most common side effects of Ivermectin typically include nausea, vomiting, diarrhea, stomach pain, skin rashes, dizziness, etc. Ivermectin medication does not cause the side effect of male infertility.

There was no substantial evidence that suggested that Ivermectin can cause sterility in males. Hence, the Nigerian study done in 2011 is flawed as it evaluated a small sample of only 37 patients who had been diagnosed with river blindness.
