can you take ivermectin with antibiotics | Important Points

Ivermectin and antibiotics are both commonly prescribed medications, but can they be taken together safely?

Ivermectin is an antiparasitic drug that is used to treat a variety of parasitic infections, such as river blindness, elephantiasis, and scabies. It is also being studied as a potential treatment for COVID-19, although its effectiveness for this purpose is still being researched. Antibiotics, on the other hand, are used to treat bacterial infections and work by killing or slowing the growth of bacteria in the body.

While these two types of medications target different types of infections, they can be prescribed together if a patient is dealing with multiple infections at the same time. However, it’s important to talk to your doctor or pharmacist before taking any combination of medications, as certain combinations can interact with each other and potentially cause harmful side effects.

Interactions between ivermectin and antibiotics

Ivermectin is primarily metabolized by the liver, so it’s important to be cautious when taking this drug with certain antibiotics that can affect liver function. For example, tetracyclines, macrolides, azithromycin, and other antibiotics can interfere with the metabolism of ivermectin and cause its levels in the blood to increase.

This can lead to an increased risk of side effects such as nausea, vomiting, diarrhea, and headaches. In severe cases, high levels of ivermectin can lead to seizures, coma, and even death.

Additionally, certain antibiotics can also reduce the effectiveness of ivermectin or vice versa. For example, rifampin, a commonly prescribed antibiotic for tuberculosis, can lower the concentration of ivermectin in the blood, which can reduce its effectiveness.

Other considerations

In addition to potential interactions, there are other important considerations when taking both ivermectin and antibiotics. For example, both types of medications can cause gastrointestinal side effects such as nausea, vomiting, and diarrhea. Taking them together can increase the likelihood of experiencing these side effects.

Additionally, some antibiotics can alter the composition of the gut microbiome, which can affect the absorption and metabolism of other medications. This can be particularly important when taking ivermectin, as it is metabolized by the liver and eliminated from the body through the feces.

When to take ivermectin and antibiotics

If your doctor has prescribed both ivermectin and antibiotics to treat multiple infections, it’s important to follow their instructions closely. They will consider your health history, current medications, and the severity of your infections when deciding on the appropriate dosage and timing.

In general, antibiotics are usually taken in a course of several days or weeks, depending on the type and severity of the infection. Ivermectin, on the other hand, is typically taken as a single or a few doses depending on the type of infection. If you are taking both medications, your doctor may recommend that you take them at different times of the day to minimize the risk of interactions.

It’s important to finish the entire course of antibiotics prescribed by your doctor, even if your symptoms improve before the medication is finished. Stopping antibiotics too soon can increase the risk of antibiotic resistance, which can make future infections harder to treat.

Additionally, it’s important to take ivermectin exactly as prescribed, even if you don’t feel any immediate relief from your symptoms. It may take several days or weeks for the drug to fully eliminate the parasitic infection.

Finally, it’s important to follow your doctor’s instructions regarding any dietary or lifestyle changes that may be necessary while taking both medications. For example, some antibiotics can interact with certain foods or supplements, while others may cause drowsiness or dizziness.


Taking ivermectin and antibiotics together can be safe and effective when prescribed by a doctor, but caution is needed to avoid potential interactions and side effects. If you are taking both medications, be sure to follow your doctor’s instructions closely and report any unusual side effects or symptoms immediately.

It’s also important to remember that antibiotics should only be used to treat bacterial infections, and not viral infections such as the common cold or flu. Additionally, while ivermectin is being studied as a potential treatment for COVID-19, it has not been approved by the FDA for this purpose and should not be used as a preventative or treatment for the virus without proper medical guidance.

As always, it’s important to practice good hygiene, social distancing, and other preventive measures to reduce the risk of infection and promote overall health and well-being.
