Precautions Before Starting Use Of Ivermectin 12mg tablet

1. History Checks

You need to tell your healthcare provider about some things because they might need to change your dose of Ivermectin or give you a different treatment.

• Existing Disease: If you have Liver or Kidney Disease it can be a problem as your liver processes Ivermectin. If your liver is not working well, Ivermectin can build up to levels in your body.
• Immune disturbance: If you have a weakened immune system like if you have HIV or AIDS or if you are taking immunosuppressant’s dose, Ivermectin may not be enough to clear the infection.
• Loa Loa: If you have recently traveled to Africa, you need to be checked for Loa Loa, which is also known as “eye worm.” If you take Ivermectin and you have Loa Loa in your body, it can cause a fatal brain inflammation.

2. Physical & Demographic Constraints

There are some demographic things that your healthcare provider needs to consider when giving you Ivermectin.

• Restriction of Use: If you are a child who weighs than 15 kg, Ivermectin is not usually recommended because there is not enough information about its safety for children of that weight.
• Pregnancy: If you are pregnant, Ivermectin is typically avoided unless it is really needed. This is because it is not fully understood how Ivermectin affects a developing fetus.
• Breastfeeding: If you are breastfeeding, small amounts of Ivermectin can pass into your breast milk. Most doctors think it is an ideal to wait at least one week after giving birth before taking Ivermectin or you might need to stop breastfeeding for a little while.

• Major liver or kidney disorders or infections
• Severe seizure and fits

• Any other parasitic infection
