Cancer-stricken Dave Coulier says chemotherapy has had a ‘roller coaster’ of effects

Dave Coulier has been feeling a “roller coaster” of symptoms as he continues to battle stage 3 non-Hodgkin lymphoma.

The comedian, 65, said on Friday’s episode of his podcast “Full House Rewind” that his ongoing treatment is “going well,” though his hair has not grown back yet.

“I realize how much that hair keeps you warm,” he told co-host Marla Sokoloff. “Gets a little cold here in Michigan where I’m at.”

He joked that it will be nice in the summer, “like a little air conditioning on your head,” before conceding he was excited to have his hair grow back.

The “Full House” actor admitted that undergoing chemotherapy to battle the blood cancer has been a “roller coaster ride” of “different effects.”

“People who are watching the show or listening to the show, who have been here before, you know that it’s a roller coaster, because the side effects have side effects — and then you take a drug to counteract that and this and that.”

He called it a “constant cocktail where your body is in fight or flight mode” as your body attempts to adjust.

“It’s a little bit of an internal battle,” Coulier said.

Coulier revealed he was diagnosed with cancer in November 2024.

“[I was] feeling like I got punched in the stomach because it never happens to you,” he said of the moment he learned of the diagnosis. “You always hear about it happening to someone else.”

He previously called chemotherapy “intense” and said it “scared the daylights” out of him.

“There [are] days where I feel unbelievable,” he said. “Then there’s other days where … I’m just going to lay down and let this be what it’s going to be.”

Before his diagnosis, the “Fuller House” actor thought he just had “a little bit of a head cold.”

During his treatment, pal John Stamos caught flack for donning a bald cap in “solidarity” instead of actually shaving his head, though Coulier made it clear he appreciated the gesture nonetheless.

Coulier is expected to finish treatment in February 2025 after undergoing six rounds of chemo every three weeks.
