Is there a way I can pass hard stool without anymore medication?

Maybe. This depends greatly on why the stool is hard, other medical problems, and what you have already used. The best remedy is plenty of water, which can help to soften stool. Physical activity can also help. Assuming no severe intestinal pathology, there is little reason to avoid stool softeners like docusate, or non-stimulant laxatives like miralax (polyethylene glycol).
