The 51-year-old "My Man Is a Lo ser" actor announced his return on social networking site Twitter.
"I'm back! Took a month to take care of things. Healthy. Feeling grateful for the love and support of family and friends," Stamos wrote.
The actor was arrested last month after police officers were alerted that he was drinking when he started driving erratically along Santa Monica Boulevard.
Stamos checked into a rehab to seek help for his irregular drinking habit, after getting charged.
He is set to appear before a judge for the DUI (Driving Under the Influence) charge on September 11.
