Parasitic infections can infect different parts of the human body. Such infections can lead to different health problems. Doctors usually recommend different medicines that can kill the parasites. One such medicine that can treat parasitic infections quickly is Ivermectin.
Patients usually ask how long it takes the medicine to start working in the body after they take it. The answer depends on the type of parasite and the patient’s health condition. Knowledge of how the medicine works can help in understanding the time frame.
How Ivermectin Works in the Body
The mechanism of action of Ivermectin is that it attacks the nervous system of parasites. The drug binds to channels in the parasites’ cells. These channels are responsible for the transmission of nerve signals and muscle movement. Ivermectin blocks these channels, thus paralyzing the parasites.
Paralyzed parasites cannot eat or reproduce. Eventually, the body’s immune system removes those parasites. This process gradually eliminates parasites from the body. The drug acts on parasites without affecting human nerve cells when used correctly. This is why Ivermectin is effective against various parasites.
How Fast Does Ivermectin Work to Kill Parasites
The time taken by the drug to kill the parasites depends on the infection. However, the drug usually starts to work within a few hours of taking it. The drug reaches its peak blood concentration in 1 day. This enables the drug to start working on the parasites quickly.
The parasites may start dying within 24 to 48 hours. However, the body may take a few days or weeks to rid itself of the parasites. The patient may start feeling better during this period. Recovery depends on the infection. However, the patient may need to take more doses of the drug. This ensures the complete elimination of the parasites. The patient needs to follow the doctor’s instructions to get the best results.
Let us discuss how the drug acts on different parasites.
Scabies: Ivermectin begins to take effect against scabies mites within 12 to 24 hours after taking the first dose. However, itching may persist for 1 to 2 weeks. This happens because, even though the drug kills the mites, the itching persists. The treatment for scabies is one dose of Ivermectin. A second dose is sometimes given 1 to 2 weeks later to clear all the mites.
Lice: For head lice, oral Ivermectin eliminates live lice in 24 hours with a quick reduction in active infestation rates. Topical ivermectin kills lice in 10 minutes. Research revealed that patients who used a single application of topical ivermectin lotion were lice-free for 15 days. It was also revealed that topical ivermectin is as effective as oral ivermectin for treating head lice. Repeat treatment with oral ivermectin at days 7-10 increases efficacy and prevents reinfestation, leading to near-complete clearance by 2 weeks.
Strongyloidiasis: It is one of the most common worm infections for which doctors often prescribe Ivermectin. This type of worm infects the human digestive system. It often results in pain in the abdomen and diarrhea. The drug works by eliminating the worms from the body. The activity of Ivermectin on the intestinal nematodes (Strongyloides) occurs a few hours to a few days after the consumption of the drug. Parasite clearance from the stool occurs over 1 to 2 weeks. However, the drug may need to be repeated if the symptoms persist.
Onchocerciasis: Ivermectin also treats Onchocerciasis. It is a condition that is caused by an infected blackfly bite. The condition can cause serious skin and eye damage. Treatment with Ivermectin can help manage the condition. Ivermectin is commonly used to treat onchocerciasis, also known as river blindness. This is a parasitic worm infection spread by bites from infected black flies. This infection results in serious skin problems and vision difficulties. Once the drug is ingested, it begins working in a few hours. It quickly enters the bloodstream and targets the tiny parasite larvae called microfilariae. Within 24 to 48 hours, the drug works by paralyzing and killing these parasite larvae. This helps relieve symptoms such as itching and skin irritation.
Factors That Affect Treatment Time
Several factors can affect the rate at which parasites die. Some of them are:
- The type of parasite is one of the main factors. Some parasites will die faster than others.
- The severity of the infection is also a factor. The parasites in a mild infection will probably die faster than in a severe one. People with strong immune systems probably get well, whereas those with a weaker immune system do not.
- The drug’s dosage is also a factor. The dosage is calculated depending on body weight and medical condition. The right dosage ensures that the drug kills the parasites effectively.
Conclusion
Ivermectin is a powerful drug that doctors prescribe for the treatment of a number of parasitic infections in humans. In most instances, the drug starts working on the parasites on the first day after consumption. Nevertheless, the total eradication of the parasites from the body may take a few days or weeks.
The duration of the drug’s effect depends on the type and severity of the infection, as well as the patient’s overall condition. With the right medical advice and dosage, the drug effectively clears parasites from the body and improves the body’s condition.
