Pinworm infection in adults presents with an intense itching sensation in the folds of skin surrounding the external anal sphincter and increase in intensity at night, according to MedicineNet and Healthline. Pinworm infections that involve a small number of worms may be very mild or asymptomatic. In rare cases, severe infections cause a loss of appetite, irritability, insomnia and weight loss, according to MedicalNewsToday. Though rare, these symptoms may increase in intensity after the eggs mature and hatch.
The symptoms of a pinworm infection usually develop a few weeks after the eggs have been ingested and the adult female pinworm makes her way to the anal area through the colon and the rectum to lay her eggs, explains MedicalNewsToday. Symptoms of a pinworm infection usually subside after the administration of over-the-counter deworming drugs such as albendazole, pyrantel pamoate and mebendazole accompanied by the use of a lotion to relieve itching, Healthline notes.
