Promethazine dosage chart

Always consult your doctor or pharmacist before using Promethazine. This chart provides general guidelines, but individual needs vary significantly based on factors like age, weight, and medical history. Dosage adjustments are common and should be made under professional supervision.

For adults, the typical oral dose for nausea and vomiting ranges from 12.5mg to 25mg every 4 to 6 hours, not exceeding 75mg in 24 hours.

Remember, exceeding the recommended dose can lead to serious side effects. Common side effects include drowsiness, dizziness, and dry mouth. Severe reactions are less frequent but potentially life-threatening, highlighting the necessity of strict adherence to prescribed dosages and careful monitoring for any adverse reactions. Seek immediate medical attention if you experience significant side effects. This chart serves as a starting point, and a personalized treatment plan is vital for safe and effective Promethazine use.

Understanding Promethazine: Uses and Indications

Promethazine is a medication with several key applications. Primarily, it acts as an antihistamine, effectively relieving allergy symptoms like sneezing, runny nose, and itchy eyes. This makes it useful for treating allergic rhinitis and urticaria (hives).

Nausea and Vomiting Relief

Beyond allergy relief, promethazine is a valuable tool in managing nausea and vomiting. Doctors frequently prescribe it to treat postoperative nausea, nausea associated with motion sickness, and nausea from other causes. Its antiemetic properties can significantly improve patient comfort.

Sedative Effects and Use in Preoperative Settings

Promethazine also possesses sedative properties. This makes it helpful as a pre-operative medication to calm patients before surgery or other medical procedures. However, remember that the sedative effect is a secondary function, and dosage should be carefully managed by a medical professional.

Always consult a doctor or pharmacist before taking promethazine or any other medication. They can help determine the appropriate dosage and address any potential interactions with other medications you are taking.

Calculating Child’s Dosage

Your doctor will calculate the appropriate dose based on your child’s weight in kilograms (kg).
