Pinworm is one 100 mg tablet
The same dosage schedule applies to adults and pediatric patients two years of age and older. The Emverm indication starts with patients two years of age and older. The tablet may be chewed, swallowed, or crushed and mixed with food.
Pinworm, Enterobius vermicularis, is the column that says 1 tablet once. One 100 mg tablet is the whole labeled pinworm course. It is not the first half of a three-day course, and it is not an automatic second tablet two weeks later.
Whipworm, roundworm, and hookworm take three days
Whipworm (Trichuris trichiura), roundworm (Ascaris lumbricoides), and both hookworms on the Emverm list (Ancylostoma duodenale and Necator americanus) use the other column: 1 tablet morning and evening for 3 consecutive days. That is two 100 mg tablets a day, for three days. A sentence that gives every worm the three-day line has erased the pinworm column.
Convulsions in infants below the age of 1 year have been reported. Emverm's labeled patients are two years of age and older. Do not take Emverm with metronidazole (a medicine used to treat bacterial and protozoan infections) as serious skin reactions called Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) can happen.
A second course waits three weeks, and only if needed
If the patient is not cured three weeks after treatment, a second course of treatment is advised. The label does not print a day-14 tablet as the ordinary next step. The second course is for a patient who is not cured three weeks after treatment. Hygiene in the house still matters for pinworm eggs, and that is a separate problem from inventing an extra tablet the label did not schedule.
No special procedures, such as fasting or purging, are required. Which worms earn the tablet is the mebendazole uses note. How the drug was developed is mebendazole history.
The US 500 mg chew is not this tablet
The recommended dosage in patients one year of age and older is one VERMOX™ CHEWABLE 500 mg tablet taken as a single dose. Do not swallow the tablet whole. That product is labeled for Ascaris lumbricoides (roundworm) and Trichuris trichiura (whipworm). It is not the 100 mg Emverm tablet, and it does not borrow the pinworm column. The medicine page on this site is Vermox. The 100 mg text is the Emverm label. The 500 mg text is the Vermox Chewable label.
