Have used Bisacodyl 5 mg for constipation and wondering how it compares to sennosides 25 mg
Sennosides is a stimulant laxative. It works by irritating bowel tissues, resulting in bowel movements.
Bisacodyl is a laxative that stimulates bowel movements. It is used to treat constipation or to empty the bowels before surgery, colonoscopy, x-rays, or other intestinal medical procedure.
They both work to relieve constipation but their modes of action are slightly different. Try the Senna-Lax and see how it works for you.
For me, these two may be thought of as being essentially the same drug, but in two different strengths, as they both work via similar mechanisms but bisacodyl is considerably stronger — by a factor of 5× in my estimation.
I tend to see them the way I view two benzodiazepines : diazepam (Valium®) and alprazolam (Xanax®). Both those also work via the same mechanism of action more or less, but alprazolam is considerably stronger (in this case 10×) so the user can take 10mg diazepam or 1mg alprazolam and have similar effects. In this example there are in fact other differences to consider, such as each drug's half-life, but I'm referring only to strength.
So you can take let's say 50mg of sennosides or 10mg of bisacodyl and the strengths will be similar. But, that said, for me bisacodyl has an added benefit, in that it is "more certain". Put another way, I have never needed to take a second, smaller dose of bisacodyl several hours after the first because of the first dose not delivering (so to speak), whereas I have indeed needed to do that with sennosides a few times.
Not everyone is the same of course, but let me say this... if someone who didn't know anything about this stuff were to ask me for a recommendation, I'd just straight up tell them to take 10mg bisacodyl, wouldn't really need to mention the senna.
