Using PIN RID® : What to Know
What is PIN RID® used for?
PIN RID® is an over-the-counter, prescription-strength, chewable medicine used to treat and eliminate pinworms and other common intestinal parasites such as roundworms, hookworms, whipworms, threadworms, and tapeworms. It’s clinically tested, doctor recommended, and trusted by healthcare professionals since 2021.
How does PIN RID® work?
The active ingredient, Pyrantel Pamoate (720.5 mg), paralyzes and kills intestinal worms by stopping them from absorbing essential nutrients. The body then removes them naturally through the digestive tract. The PIN RID® chewable disintegrates in under 10 minutes, beginning fast-acting relief.
How can I prevent pinworms from coming back after treatment?
To prevent reinfection or spreading pinworms to others, it’s important to combine treatment with proper hygiene for at least two weeks. Follow these steps:
- Wash hands thoroughly with soap and water before eating and after using the bathroom or changing diapers
- Keep fingernails short and clean
- Avoid scratching the anal area
- Wash bedding, clothing, towels, and toys in hot water and dry them on high heat
- Vacuum and dust regularly
- Disinfect bathrooms and high-touch surfaces
- Treat all household members with PIN RID® at the same time – even if they aren’t showing symptoms – using the appropriate dose based on each person’s body weight as directed on the product label
Always consult a healthcare provider if symptoms persist or if you’re unsure of the correct dosage for young children.
Do I need a prescription to buy PIN RID®?
No. PIN RID® is available over the counter and does not require a prescription. Although it contains prescription-strength ingredients, it can be purchased directly without visiting a doctor.
That said, if you have concerns about symptoms, recurring infections, or if you’re unsure whether deworming is appropriate, it’s always a good idea to speak with a healthcare provider. Consulting a doctor is your choice and may be helpful, especially for young children, persistent cases, or anyone with underlying health conditions.
What types of worms does PIN RID® treat?
PIN RID® was primarily formulated to treat pinworms, the most common intestinal worm infection in the U.S. However, its clinically studied ingredients are also highly effective against a broad spectrum of intestinal parasites, including roundworms, hookworms, whipworms, threadworms, and tapeworms.
Many of these worms – such as roundworms and hookworms – can be transmitted from pets to humans, especially in households with close animal contact or young children. That’s why PIN RID® is a great option when the exact worm type is unknown, or when general deworming is needed for family-wide protection, especially in pet-owning households.
Is PIN RID® safe for children?
Yes. PIN RID® is safe for children ages 2 and older when used as directed. It is a chewable, over-the-counter treatment that’s designed to be easy for kids to take and effective with just a single dose.
Refer to the Dosing page for complete instructions on how to use PIN RID® .
Always follow the directions on the label carefully and consult a healthcare provider if you have any concerns, especially for younger children or if symptoms persist after treatment.
Is PIN RID® a single-dose treatment?
Yes. PIN RID® is designed to be effective with just a single dose in most cases, and that’s been the experience of many families using it. However, because pinworm reinfection is common – especially in households with multiple children or pets – a second dose after 2 to 3 weeks may be recommended to help break the cycle and ensure full resolution.
Always follow the dosing instructions on the label, and consult a healthcare provider if symptoms persist or return.
Do all family members need to take it?
Yes. Because pinworms are highly contagious, it’s recommended that the entire household — even those without symptoms — take PIN RID® at the same time to stop the spread.
How should PIN RID® be taken?
PIN RID® should be chewed and swallowed – no mixing, measuring, or messy liquids required. The dosage is based on 5 mg per pound of body weight, and each chewable tablet contains 720.5 mg of Pyrantel Pamoate. Refer to the Dosing page for complete instructions on how to use PIN RID®.
To make dosing easier, tablets are scored, so they can be split in half when needed-especially helpful for younger children.
What are the common signs of pinworm infection?
Pinworm infections can cause a range of symptoms, which may vary between children and adults. Many people – especially adults – may experience no symptoms at all. However, when symptoms are present, they are usually related to irritation caused by the female worms laying eggs around the anus, typically at night.
In Children:
Children are more likely to show noticeable symptoms, including:
- Itching or discomfort around the anus (especially at night)
- Restless sleep or waking frequently
- Irritability, mood changes, or trouble focusing
- Scratching the anal area, sometimes leading to redness or skin irritation
- Appetite changes or mild stomach discomfort
- Visible small white worms (resembling tiny threads) in underwear, stool, or around the anal area
- Occasional bedwetting or increased nighttime awakenings
Because children often struggle to articulate what they’re feeling, behavioral changes or sleep disruption are often early signs.
In Adults:
Adults may have milder symptoms or none at all. When present, they typically include:
- Mild to moderate itching around the anus, often worse at night
- Sleep disturbances or fatigue due to discomfort
- Irritation in the vaginal area (in some cases, pinworms can migrate)
- Mild gastrointestinal discomfort or bloating
- Occasionally seeing worms in stool or on toilet paper
Adults tend to have lower worm burdens than children, so symptoms may be less intense or overlooked.
When to See a Doctor:
While PIN RID® is effective for treating pinworms at home, consult a healthcare provider if:
- Symptoms persist or worsen after treatment
- There’s a suspected vaginal or urinary tract involvement
- Reinfection keeps occurring despite treatment and hygiene practices
- You’re unsure whether the symptoms are caused by pinworms
Can adults take PIN RID® too?
Absolutely. PIN RID® is safe and effective for adults as well as children ages 2 and up, when taken according to the dosing directions based on body weight. Pinworms are not just a childhood issue – they can affect people of any age. Adults often have milder or even no symptoms at all, which is why treating the entire household is a key part of effective pinworm control.
Why Adults Should Take PIN RID®
Even if adults aren’t experiencing symptoms, they can still carry and spread pinworms. Since the infection is highly contagious and spreads through microscopic eggs – often on hands, bedding, clothing, or surfaces – it’s very common for multiple members of a household to become infected, even if only one person shows symptoms.
That’s why adults should take PIN RID® if:
- They have confirmed or suspected pinworm infection
- Their child or another person in the household has pinworms
- They share a bathroom or bedroom with someone who has symptoms
- A pediatrician or healthcare provider recommends treating the whole household (which is often the case)
Treating the Whole Household Matters
To stop the pinworm lifecycle and prevent reinfection:
- Everyone in the household should take a dose of PIN RID® at the same time, even if they don’t feel sick
- A second dose may be needed after 2 – 3 weeks to ensure any new worms (hatched from eggs after the first treatment) are eliminated
- Hygiene measures like frequent hand washing, hot laundering of linens, and cleaning of surfaces should also be practiced during this time
This group treatment strategy is especially important in households with young children, where hygiene habits are still developing and reinfection is more likely.
Refer to the Dosing page for complete instructions on how to use PIN RID®.
Are there any side effects?
Side effects from PIN RID® are rare and usually mild when they do occur. The most commonly reported effects include:
- Mild stomach discomfort or cramps
- Nausea
- Dizziness
- Headache (occasionally)
These symptoms typically go away on their own shortly after treatment and do not require medical attention in most cases.
However, if any side effects persist, worsen, or become bothersome, it’s best to contact a healthcare provider to ensure appropriate care – especially in young children or individuals with existing medical conditions.
As with any medication, allergic reactions are possible, though extremely rare. Seek immediate medical help if you experience symptoms such as rash, itching, swelling (especially of the face or throat), or difficulty breathing.
Is PIN RID® allergy-friendly and clean-label?
Yes. PIN RID® is thoughtfully formulated with clean, allergy-conscious ingredients and held to high safety and quality standards. It’s designed for families who care about what goes into their bodies – especially when treating children.
PIN RID® is:
- Third-party clinically tested for safety and effectiveness
- Non-GMO and plant-based
- 100% free from parabens, toxins, heavy metals, and synthetic dyes
- Free from artificial sweeteners
- Dairy-free, soy-free, and gluten-free
- Kosher certified
- Clinically clean and safe for regular use
This makes PIN RID® a smart choice for families looking for a gentle, effective, and trustworthy deworming solution – especially those with dietary sensitivities or ingredient concerns.
Can I take this while pregnant or breastfeeding?
If pregnant or nursing, consult a healthcare provider before using any deworming medication.
Will I need to clean my home after treatment?
Yes. Because pinworm eggs are highly contagious and can survive on surfaces for up to 2 – 3 weeks, cleaning your home thoroughly after treatment is an essential step in preventing reinfection.
To help stop the cycle, we recommend the following:
Launder frequently touched items
- Wash bedding, pajamas, underwear, clothing, and towels in hot water daily for at least the first few days after treatment
- Use high heat in the dryer to kill any lingering eggs
Disinfect high-touch surfaces
- Wipe down bathroom surfaces, toilet seats, light switches, doorknobs, and remotes with disinfectant or diluted bleach solution
- Clean toys, tabletops, phones, and other shared items regularly
Vacuum and dust daily
- Focus on bedrooms, carpets, rugs, and upholstered furniture, especially around where infected individuals sleep or spend time
- Avoid shaking linens or clothing, which can spread eggs into the air
Practice personal hygiene
- Encourage daily morning showers (not baths), especially for children
- Promote frequent handwashing, especially before eating and after using the bathroom
- Keep fingernails short and clean, and discourage nail-biting or scratching
Treat the whole household
Even if symptoms are not present, everyone in the home should be treated at the same time to prevent the infection from spreading back and forth.
How is PIN RID® different from other dewormers?
PIN RID® is the only chewable, prescription-strength dewormer available over the counter, making it uniquely easy to take – especially for children who struggle with swallowing pills or messy liquids.
Here’s what sets it apart:
- Clinically studied ingredients: PIN RID® contains pyrantel pamoate, a well-established and clinically studied anthelmintic (deworming agent) used by healthcare providers for decades.
- Chewable format: No mixing, measuring, or swallowing large pills – PIN RID® is a pleasant-tasting chewable tablet that’s easy for children and adults alike.
- Single-dose power: Designed to be effective with just one dose in most cases, making treatment simpler and more convenient.
- Doctor-backed and family-approved: Developed with input from medical experts and trusted by thousands of families.
- Clean-label & allergy-friendly: Free from synthetic dyes, parabens, artificial sweeteners, and common allergens like dairy, soy, and gluten.
- Made in a GMP-certified facility: Manufactured in a facility that meets Good Manufacturing Practice (GMP) standards, ensuring consistent quality, safety, and purity in every batch.
PIN RID® combines clinical credibility with family-friendly convenience-making it a modern, accessible solution for pinworms and other common intestinal worms.
How do I choose the right count - 6, 12, or 24 tablets - for my household?
The right tablet count depends on the number of people in your household, their body weight, and whether you plan to administer a second dose after 2 – 3 weeks (which is often recommended to help prevent reinfection).
Each person’s dose is determined by their weight. Adults and older children generally need 2 – 4 tablets per dose, while younger children may only need ½ to 1½ tablets.
Here’s a general guide:
6-Count Pack
Best for:
- 1 adult (single-dose)
- 1–2 small children (based on lower body weight)
- Trial use or backup for travel
12-Count Pack
Ideal for:
- 1 adult + 1–2 children
- 2–3 people planning to take a second dose
- Smaller households needing coverage for a follow-up treatment
24-Count Pack
Recommended for:
- Larger families (4+ members)
- Multiple adults or older children (who need 2–4 tablets each)
- Households, classrooms, or camps where group exposure is a concern
- Ensuring enough tablets for two full rounds of treatment
When in doubt, choose the larger count to ensure your household is fully covered for both the initial and follow-up doses. Always refer to the weight-based dosing chart and follow label instructions carefully.
Can I take PIN RID® without knowing exactly which type of worm I have?
Yes. Many people take deworming medication without a confirmed diagnosis because intestinal parasites often go undetected or misdiagnosed. Symptoms like itching, digestive upset, irritability, and fatigue may indicate a worm infection — and in households with pets or young children, risk of exposure is higher.
PIN RID® uses a broad-spectrum, clinically backed deworming ingredient that’s effective against common intestinal worms, including pinworms, roundworms, and hookworms. Deworming regularly — especially if you have pets, young kids, or frequent outdoor exposure — can support better gut health, comfort, and peace of mind.
As always, if symptoms are severe or persistent, it’s best to consult your healthcare provider.
What does it mean that PIN RID® won the Mom’s Choice Award®?

Who is most likely to get pinworms or other intestinal worms?
Pinworms and other intestinal parasites are most common in young children — especially those in preschool, daycare, or elementary school — because they often play in close quarters and may forget to wash hands thoroughly.
However, the entire household can easily become exposed. Adults, older siblings, and caregivers can be affected through shared surfaces, bedding, or contact with contaminated hands or clothing.
You’re also at higher risk if you:
- Live or work in group settings (schools, camps, healthcare, etc.)
- Have pets in the home, especially if they go outdoors
- Travel frequently or live in areas with limited sanitation
- Share bathrooms or towels with others
Because worms are highly contagious, it’s often recommended to treat the whole family at once — even if only one person is showing symptoms.
Why is a chewable tablet better than a liquid dewormer?
Chewable medications like PIN RID® offer several important advantages over traditional liquid dewormers – especially for families with children:
Easier to Take
Chewables are mess-free, portable, and simple to dose, making them ideal for kids, older adults, and anyone on the go. There’s no measuring, no spills, and no clean-up.
Kid-Friendly Taste
Many children struggle with the bitter taste of liquid medications. PIN RID® features a pleasant bubble gum flavor that’s easier for kids to accept – making treatment less stressful for parents and children alike.
More Accurate Dosing
Chewable tablets are pre-measured for weight-based dosing, which helps ensure accuracy and reduces the risk of under- or overdosing that can occur with liquid measuring spoons or syringes.
Convenient and Affordable
Unlike prescription liquid dewormers – which can cost hundreds of dollars and may require insurance approval – PIN RID® is an affordable, over-the-counter option available directly to families without a prescription.
Rising Consumer Preference
Chewables are becoming the preferred form for many families seeking taste, ease, and simplicity, with increasing demand for clean-label, user-friendly alternatives to traditional liquid medicine.
In short, chewable dewormers like PIN RID® are a smarter, cleaner, and more family-friendly choice—without the mess, stress, or extra cost of liquid options.
