The powder form, which is the focus of this discussion, is typically used in compounding pharmacies to create custom formulations. However, it's important to understand the full range of available forms to appreciate the versatility of this medication.
Tablets are one of the most common forms of Promethazine HCl. They come in various strengths, typically ranging from 12.5 mg to 50 mg.
