I wondered about whether Zofran (generic name, Ondansetron) was habit-forming, and this was the first Google.Com entry.
I have to admit I am a guy, so not entirely sure what you ladies are experiencing. My doctor prescribed it since I was vomited (sorry to be gross!) either at time of taking a handful of pills or inexplicably. She told me Zofran is usually prescribed for cancer patients undergoing "chemotherapy", so I realized it was strong.
I have been on two types: CVS has dissolvable peppermint-tasting Ondansetron and Kroger Pharmacy had disssolvable strawberry-tasting. I am pretty sure that has played some role in my use of Zofran. It usually takes about 15 minutes for effectiveness, for me.
When I was last on a cruise, I remember "popping a pill" of it --"just in case." Like an earlier subscriber mentioned, she'd take twice the dose prescribed. Mine come in blister packs, two pills side by side, so I'd pop two also.
I was able to get away from Ondansetron for a while, but like most "helpful meds" I have been prescribed (such as Adderall [amphetamine salts, for Attention Deficit Disorder]) and Klonopin [generic name, clonazepam] for anxiety), I always request Ondansetron to be refilled --whether needed or not. With these three, I am like that. Adderall is a "controlled substance" here in HOUTX (Houston, TX, USA) where I live, not sure in other places, so a special prescription pad has to be used by my doctor --it cannot be automatically refilled by CVS.
I appreciate that each of you have shared your experience. I hope that I can "remain clean" of Ondansetron. I have an "addictive personality" coming from alcoholism on both sides of my family. My sister, whom I love more dearly than you can imagine, cannot handle alcohol. She gets very emotional and has "blackouts." We're Iro-American (for distant Irish heritage) on my father's side and there is Cherokee Amerindian on Mama's side.
