What Happens to Your Body After Taking Ivermectin?
Updated: Sep 25
What happens to your body after taking Ivermectin is a common question among the US folks. Well the answer depends on the medicine processing and the patient's condition. Usually when someone takes an oral ivermectin tablet USP, the drug starts working in the body within a few minutes.Then begins absorbing into the bloodstream in 30 minutes and processed mainly by the liver organ. Later the drug was removed through the kidney's natural elimination processes.
However, what happens after taking Ivermectin, may vary person to person, age, health condition and severity of the infection. Factors such as type of infection, parasite involved, prescribed dose, certain food intake, and individual health. These all play a significant role in the whole process. Here in this blog we are providing you complete knowledge of ivermectin drug processing in the body after taking an oral dose.
How Does Ivermectin Work in the Body?
Once an Ivermectin tablet is swallowed with the help of water, the medicine passes through the digestive system and starts absorbing. Suppose if you take a 12-mg dose of ivermectin on an empty stomach, then the medicine usually reaches its highest level in the blood in about 4 hours. However, the amount absorbed can vary depending on food intake and other individual factors.
After absorption, ivermectin is moved through the bloodstream and mainly processed through the liver. Once the process is done most ivermectin and its metabolites are then removed through the stool, while less than 1% of the determined dose is passed through urine.
The action against parasites is more specific. It binds glutamate-gated chloride channels that are found in the cells of susceptible invertebrate parasites. This develops chloride movement into the parasite's cells, interfering with their normal activity to stop them. As a result, the parasite couldn't move instead they got paralyzed and eventually died.
Day-by-Day Ivermectin Treatment Timeline
There is no single day-by-day ivermectin treatment timeline that applies to every patient. The medicine may be prescribed as a single dose or according to a different schedule depending on the patient condition and stage of the infection. So, a fixed timeline such as “Day 1 kills the parasites, Day 2 removes them, and Day 3 cures the infection” this would create a misleading picture. However, the appropriate treatment could be measured through the below mentioned timeline.
Day 1: Absorption and early action
After the oral tablet is consumed, ivermectin starts absorbing and begins circulating in the body.The medicine may reach its highest blood level a few hours after an oral dose. During this period, the medicine can begin acting on susceptible parasites to decrease its effect.
You may not notice a change in symptoms on the same day. But that does not mean that the drug is ineffective or the treatment is not working. You may notice a change later in 3 to 4 days.
Days 2–3: The response may start becoming noticeable
As treatment continues to work symptoms may begin to change. Some people may feel better or recover quickly, while other patients' bodies may take a longer period to adjust with medicine and remove symptoms.
However, feeling better does not always mean that the parasites have completely disappeared; it may reoccur if a patient does not follow the treatment instructions given by the doctor. Here, the parasite, its life stage, and the body's response all matter.
Days 4–7: The body continues processing the medicine
Ivermectin does not simply remove after the first day of treatment. Its plasma half-life is approximately 18 hours which means the amount of the drug in the bloodstream gradually removes over time.
That is why doctors advised patients to not take another dose when they skip or forgot to take the dose. The right dose and treatment duration depend on the condition and must be determined by a healthcare professional after examining the condition of the individual.
After the first week
After a week ivermectin and its metabolites gradually start removing from the body. Most of the drug and its metabolites are passed out through the stool in about 2 weeks. However, the level of unchanged ivermectin in the present in the blood starts dropping much earlier since the drug has a relatively short half-life.
If a patient's symptoms remain as it is, or get worse over time, or reoccur after treatment. it is important to seek doctor’s consultation rather than taking more doses of ivermectin on your own. A healthcare professional can decide whether further treatment is needed or not.
How Long Does Ivermectin Stay in the System After an Oral Dose?
Usually after consuming oral tablets by mouth, ivermectin plasma half-life is reckoned to be about 18 hours. This means about half of the medicine is cleared from the bloodstream during this time.
However, this does not mean the medicine is completely removed after 18 hours. Your body continues to process and remove ivermectin through the body's natural elimination process and its metabolites after blood levels decrease. According to prescribing information, ivermectin and/or its metabolites are mainly passed out through the stool in about 12 days. Therefore, the half-life and complete elimination time are different.
Factors That Affect the Ivermectin
There are various factors that contribute in changing how ivermectin behaves or work on the parasitic infection after taking an oral dose.
Dose: Blood exposure generally increases with the dose, although the exact response still depends on the individual body adjustment to the medicine.
Food: Certain food can influence ivermectin exposure. In the prescribing information, a high fat meal can increase ivermectin bioavailability by about 2.5-fold compared with fasting according to a study.
Liver function: Ivermectin is metabolized mainly through the liver. Changes in liver function can therefore be relevant when considering how the medicine is handled by the patient body.
Other medicines: Drugs that affect CYP3A4 metabolism or other metabolic pathways may potentially change may affect ivermectin effect. Tell your healthcare professional about other medicines and health supporting supplements you are taking before or throughout the medication period of Ivermectin.
Type of infection: Ivermectin does not act against every parasite in the same way hence, the target parasite and its life stage can also influence the treatment response.
Conclusion
In this blog now we may clear your doubt about what happens to your body after taking Ivermectin. Once you take ivermectin, the tablet begins to be absorbed into the body and enters the bloodstream. It is mainly processed by the liver and then slowly removed from the body through the natural elimination method. The main function of Ivermectin is to diminish parasitic cells by changing their nerve and muscle functioning. The drug reaches its highest level in the blood in about a few hours.
However, how quickly the treatment works can vary. It may depend on the type of infection, the parasite being treated. The dose, certain food intake, and other individual health factors also matter during the medication and treatment period. If the symptoms do not improve or get worse, do not take an extra dose by your own rather seek advice from a healthcare provider for the betterment of health and decreasing symptoms.
