Yes, a small amount of mebendazole is absorbed into the bloodstream after oral administration, but it is considered to have poor systemic absorption.
Mebendazole is also a benzimidazole derivative with activity similar to albendazole but poorer oral absorption (<10% of the drug is absorbed systemically).
The most common adverse effects accompanying mebendazole use are loss of appetite, abdominal pain, diarrhea, flatulence, nausea, vomiting, headache, tinnitus, and elevated liver enzymes.
The excretion of Methotrexate can be decreased when combined with Mebendazole. The risk or severity of adverse effects can be increased when Mebendazole is combined with Metronidazole. The serum concentration of Mebendazole can be decreased when it is combined with Phenytoin.
2. How long does Mebendazole stay in your system? The majority of the mebendazole dosage administered orally stays in the gastrointestinal system, where it has an anthelmintic action locally. It remains in an active mode with a half-life range of 3-6 hours.
Mebendazole kills worms but not their eggs. You may need to take a second dose after 2 weeks. It's also important to have good personal hygiene to help stop the worms coming back. The most common side effect is stomach pain.
The medicine should start to work straight away but it may take several days to kill all the worms.
There have been rare reports of acute liver injury due to mebenazole, particularly when it is given repeatedly or in higher doses. The onset is usually with fever and malaise within days of starting or restarting therapy. The pattern of serum enzyme elevations is typically hepatocellular, and jaundice is uncommon.
Two drugs that can't be taken together include opioids and alcohol, or benzodiazepines and alcohol, as this combination severely slows breathing and increases overdose risk, and also aspirin and ibuprofen (or other NSAIDs), which heighthens the danger of serious bleeding or stomach ulcers, highlighting the importance of checking all medications for dangerous interactions.
Minor toxicity symptoms occur in about 20% to 30% of people taking methotrexate. This is mostly due to lower levels of folic acid in the body. Minor toxicity symptoms can include: Stomach problems such as nausea, vomiting, or diarrhea.
(The infection caused by cysts is called cysticercosis or, when the cysts form in the brain, neurocysticercosis.) These cysts cause few symptoms until the cysts degenerate and the larvae die, triggering inflammation, swelling, and symptoms such as headaches, seizures, personality changes, and mental impairment.
This medicine may cause serious skin reactions when taken together with metronidazole. Check with your doctor right away if you have blistering, peeling, or loose skin, red skin lesions, severe acne or skin rash, sores or ulcers on the skin, or fever or chills while you are using this medicine.
Acetaminophen or Tylenol® is the best known medication that can damage the liver. This medication is widely available without prescription and is present in many of the cold and flu remedies as well as in prescribed pain medications.
Enterobius vermicularis or “pinworm” infection of the liver is an extremely rare condition with only five cases previously reported in literature. It is characterized by the presence of granulomas in the liver with a necrotic core, containing adult helminthes or their ova.
Mebendazole can penetrate the blood–brain barrier and has been shown to inhibit the malignant progression of glioma by targeting signaling pathways related to cell proliferation, apoptosis, or invasion/migration, or by increasing the sensitivity of glioma cells to conventional chemotherapy or radiotherapy.
Moreover, all large-molecule products of biotechnology, such as monoclonal antibodies (mAbs), recombinant proteins, antisense, or gene therapeutics, do not cross the BBB (FIG. 1).
One of the recommendations to reduce medication errors and harm is to use the “five rights”: the right patient, the right drug, the right dose, the right route, and the right time.

High risk medications
Other drugs are used to treat worm infections outside the digestive tract, as mebendazole is poorly absorbed into the bloodstream. Mebendazole is used alone in those with mild to moderate infestations.
Here are 10 medications that in some instances can hurt the liver, plus ways to help protect it from damage.
What are the complications associated with pinworms? While serious complications are rare, pinworms can lead to: Bacterial infections: Scratching too much can break your skin, causing it to bleed and become infected.
Any worms in your gut will eventually pass out in your poo. You may not notice this. To avoid becoming infected again or infecting others, it's very important during the weeks after starting treatment to wash your hands: after going to the toilet.
❖ Change and wash underwear, nightwear (and bed linen if possible) each day. Avoid shaking clothes and linen as any eggs on them may be wafted into the air and be swallowed. ❖ Also, each day for the same 14 days it is advisable to: Vacuum and dust all household carpets, particularly those where children play.
COMBANTRIN® is only effective against adult worms, which means any eggs or immature worms inside the body might still linger after the initial treatment. In order to minimise the risk of reinfestation, a follow-up treatment two to four weeks later is strongly recommended if symptoms are still present.
