The query 'who plan B for dehydration?' arises from a common, but critical, misunderstanding. The term “Plan B” is widely recognized in the United States as a brand of emergency contraceptive. However, in global public health, particularly in the context of infectious disease management, the World Health Organization (WHO) uses “Plan B” to define a specific medical protocol for managing moderate dehydration. This article will clarify the stark difference between these two uses and outline the proper application of the WHO's rehydration strategy.
The WHO's “Plan B” for Moderate Dehydration
The WHO developed a three-tiered approach—Plans A, B, and C—to guide healthcare professionals in treating diarrheal dehydration, particularly among infants and young children.
WHO Plan A: This plan is for patients with no signs of dehydration. Treatment focuses on increased fluid intake and nutritional support at home.
WHO Plan B: This protocol is for managing patients who present with some dehydration (often referred to as moderate dehydration). Its goal is to replace lost fluid and electrolytes over a four-hour period. The amount of oral rehydration solution (ORS) administered is based on the patient's weight. For a child, the dose is approximately 75 milliliters per kilogram of body weight. The treatment is administered slowly and methodically, often with a spoon or syringe, especially if the patient is vomiting. After four hours, the patient is reassessed to determine if they need to continue with Plan B, escalate to Plan C for severe dehydration, or transition to Plan A.
WHO Plan C: For cases of severe dehydration, Plan C mandates immediate medical attention and hospitalization, typically involving intravenous (IV) fluid administration to restore fluid volume rapidly.
Understanding the Emergency Contraceptive, Plan B One-Step
Separately, in the realm of reproductive health, Plan B One-Step is an emergency contraceptive pill containing a high dose of the hormone levonorgestrel.
- How it Works: Plan B One-Step works primarily by preventing or delaying ovulation. The sooner it is taken after unprotected sex, the more effective it is.
- Function and Purpose: Its sole purpose is to reduce the risk of pregnancy after a contraceptive failure or unprotected intercourse. It does not treat or address dehydration in any way.
- Key Misconception: The name 'Plan B' is simply a brand name for this particular emergency contraception. Its purpose and composition are completely unrelated to the management of fluid loss.
Comparing the Two “Plan B”s
| Feature | WHO's Plan B for Dehydration | Plan B One-Step (Emergency Contraceptive) |
|---|---|---|
| Purpose | To treat moderate dehydration caused by fluid loss, such as from diarrhea. | To prevent pregnancy after unprotected sex or contraceptive failure. |
| Application | Administration of Oral Rehydration Solution (ORS) based on body weight over a 4-hour period. | A single oral dose of a levonorgestrel-based pill. |
| Target Population | Primarily infants and children, but can apply to adults with moderate dehydration. | Females who have had unprotected sex or contraceptive failure. |
| Active Agent | A balanced solution of water, electrolytes (sodium, potassium), and sugar. | A high dose of the synthetic hormone levonorgestrel. |
| Mechanism | Replenishes lost fluids and essential minerals to restore normal bodily function. | Prevents or delays the release of an egg from the ovary (ovulation). |
How to Recognize and Respond to Dehydration
Dehydration can range from mild to severe, and recognizing the signs is crucial for proper treatment.
- Mild to Moderate Dehydration Signs: Look for increased thirst, dry mouth, reduced urination, fatigue, and dark-colored urine. For infants, also watch for sunken soft spots (fontanelle) and irritability.
- Severe Dehydration Signs: This is a medical emergency. Symptoms include lethargy, sunken eyes, a rapid heart rate, low blood pressure, inability to produce tears, and in extreme cases, unconsciousness.
Action Steps for Rehydration:
- For mild dehydration, increasing fluid intake with water is often sufficient.
- If caused by illness with vomiting or diarrhea, use an Oral Rehydration Solution (ORS) to replace electrolytes. Over-the-counter options like Pedialyte are effective.
- Give small, frequent sips of fluid, as large gulps can induce vomiting.
- Avoid sugary drinks like soda and undiluted juice, which can worsen diarrhea.
- If signs of moderate dehydration are present, follow the WHO's Plan B protocol, especially for children.
- If severe dehydration symptoms appear, seek immediate medical attention (WHO Plan C).
Conclusion
The most important takeaway is that who plan B for dehydration is a question with two distinct answers, one related to global health and the other to reproductive health. The WHO's Plan B is a life-saving protocol for rehydrating those with moderate fluid loss, particularly in pediatric care. Conversely, the emergency contraceptive known as Plan B is a hormone-based medication for pregnancy prevention and serves no purpose in treating dehydration. Understanding this crucial difference ensures that the correct medical intervention is sought for the specific health issue at hand. When in doubt about medical treatment, always consult a qualified healthcare professional.

Oral Rehydration Strategy (WHO Plan B)
Administration During Rehydration
This involves a four-hour treatment period where the patient receives a specified volume of ORS based on their weight. For example, a child weighing 10 kg would receive 750 ml of ORS over four hours.
Small, Frequent Sips
ORS should be given in frequent, small sips using a spoon or cup to prevent vomiting, especially in children. If vomiting occurs, stop for 10 minutes and then resume at a slower pace.
Ongoing Reassessment
After the initial four-hour treatment, the patient's hydration status is reassessed. Based on the outcome, the next course of action—repeating Plan B, escalating to Plan C, or moving to Plan A—is determined.
Continued Feeding
Breastfeeding infants should continue to nurse throughout the rehydration process. After rehydration is complete, regular feeding, including food and other fluids, should be resumed.
Caregiver Education
Caregivers are instructed on how to prepare and administer ORS and how to recognize signs of worsening dehydration, ensuring they can continue treatment safely at home if necessary.
