Call the doctor if your child complains of itchy skin or always seems to be scratching the anal or vaginal area. Also ask if pinworms could be why your child has trouble sleeping or has begun to wet the bed. (Pinworms can irritate the urethra — the tube through which pee leaves the body — and lead to bedwetting.)
Call Your Doctor If:
Pinworm is seen. Skin around the anus gets red or tender. Anal itching lasts more than 1 week. You think your child needs to be seen.
Most people don't experience serious complications from pinworm infections, but in rare cases the following complications can occur: Urinary tract infections (UTIs). UTIs can develop if you do not treat the pinworm infection. Vaginitis and endometritis.
Typical pinworm infections don't cause serious problems. In rare circumstances, heavy infestations can cause infection of female genitals. The parasite can travel from the anal area up the vagina to the uterus, fallopian tubes and around the pelvic organs.
Pinworms do not cause abdominal pain, bloody bowel movements,fevers, or poor appetite. If the person has any of these signs or symptoms, they may have a more serious condition and should call a doctor or visit the hospital's emergency department.
If your child develops a pinworm infection, try not to worry. Pinworms don't cause any harm (just itching and restless sleep), and it won't take long to get rid of them.
When to seek medical care. Pinworm is not serious, but it is easily transferable between household members. If you suspect a Pinworm infection, schedule a visit with your healthcare provider so your whole family can begin treatment. You may have to do a “tape test” with your kiddo to confirm a diagnosis of pinworm.
How long does pinworms last? The life cycle of a pinworm is 4 to 6 weeks. Without treatment, infestation will continue as long as fresh eggs are being swallowed, unless a person develops immunity to pinworms, which is unusual before age 15.
Pinworms can usually be treated completely with two doses of over-the-counter medicine called pyrantel pamoate, available in the United States under the brand names Pin-X and Reese's Pinworm Medicine. Take one dose immediately and another dose two weeks later.
Treatment for pinworm infection
Medication is available to kill the worms and this is usually prescribed for the person who is infected and all other members of the household. One dose may be followed up with a second dose 2 weeks later to take care of any surviving worms.
If a person with a pinworm infection touches their underwear, bedsheets, or their anus, they can pick up eggs on their fingers. If they touch another surface, they can leave the eggs there. Anyone who touches that surface and then touches their mouth is at risk of infection.
Washing your hands with soap and warm water after using the toilet, changing diapers, and before handling food is the most successful way to prevent pinworm infection.
Complete die-off within the tested exposure time range was noted for 70 °C, 75 °C and 80 °C, however treatment at 60 °C and 65 °C allowed for development of a few eggs after incubation.
Reinfection does happen with pinworm
Eggs are swallowed, usually after hand-to-mouth contact, and the pinworm infection begins again. Pinworm eggs may spread to shared surfaces, such as bedding, curtains, toilets, doorknobs, towels, utensils, and furniture. These areas should be kept clean to avoid reinfection.
Wash all clothes, towels, and bedding. Do this often, and especially on the first day after treatment. Dry them in a heated dryer.
The eggs pass into the digestive system, where they hatch. About 1 to 2 months later, adult female pinworms lay eggs on the skin right around the anus, which makes the area itchy. Often, this happens at night.
Mebendazole does not kill the worms' eggs, and these can cause reinfection and also infect other people. A doctor or pharmacist may advise you to take mebendazole again after 2 weeks, to stop reinfection. However, if the infection comes back, speak to a doctor for advice.
People of all ages can become infected with pinworms, but the infections are found most often in children. Caregivers and family members of infected children have a higher risk of infection.
Adults are rarely affected, except for parents of infected children. Infection often occurs in more than one family member. While an infected person sleeps, female pinworms crawl out of the anus and lay their eggs on the surrounding skin.
Strict observance of good hand hygiene is the most effective means of preventing pinworm infection. This includes washing hands with soap and warm water after using the toilet, changing diapers, and before handling food.
Pinworm infection is very contagious. If you don't take precautions, it's easy to become reinfected. If anyone in your home has pinworms, take these steps to get rid of the pinworm eggs. Doing so will minimize your chances of reinfection.
If you are self-treating for pinworms, take the medication once only. Do not repeat the dose without talking with your doctor first. Depending on the type of worm infection you have, your doctor may direct you to take the medication only once or for several days.
The medicine usually takes approximately 72 hours to fully rid the system of pinworms. For several days after treatment, clean the bedroom floor by vacuuming or damp mopping. After treatment, wash bed linens and night clothes (don't shake them).
Stomach/abdominal pain, vomiting, diarrhea, headache, dizziness, or drowsiness may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly. Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects.
