Medical Detoxification

Medical detox at MHAT Treatment typically lasts 3-7 days, depending on the substance and individual factors. Our 24/7 on-site medical team monitors your progress and adjusts treatment to ensure your safety and comfort throughout the withdrawal process at our San Marcos facility.

Detoxification is the critical first step in addiction recovery. Attempting to stop using substances without medical supervision can be dangerous and even life-threatening. At MHAT Treatment, our board-certified physicians and registered nurses provide round-the-clock care using evidence-based medical protocols and medication-assisted treatment to manage withdrawal symptoms safely.

Our Detox Process

Comprehensive Assessment

Upon arrival at our facility, our medical team conducts a thorough evaluation including physical examination, substance use history, and mental health screening to develop your individualized detox plan.

Medical Stabilization

Our physicians administer medications as needed to manage withdrawal symptoms, monitor vital signs continuously, and provide comfort measures throughout the detox process.

Transition to Treatment

As withdrawal symptoms subside, our clinical team prepares you for the next phase of treatment — whether residential, PHP, or IOP — ensuring a seamless transition within our facility.
