Gentilax Laxative

can i take gentilax if im pregnant for consipation? ## Hi miriam, According to a clinical trial posted on PubMed, "phenolphthalein treatment in pregnant women associates with a higher risk for Hirschsprung's disease in their children, but this finding is only a signal which needs confirmation or rejection in other studies." NOTE: this drug is labeled under Pregnancy "Category C" meaning - Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks. With all that said, I would probably consider some (natural) dietary options for treating constipation as opposed to any prescription medications. Just to p...

when to take gentilax

Can I take gentilax in the morning? ## Hi Maria, From what I could gather, Gentilax contains the active ingredient Phenolphthalein. Apparently there is no specified time frame that one should be taking this medication. So it sounds like you can just use it as needed. A recommended oral dose is 1 to 2 tablets, however its effects are said to be cumulative by increasing or decreasing the amount you take. You can learn more about this drug on the page for Phenolphthalein Details I hope this helps! ## Maria: The active ingredient of Gentilax is phenolphthalein. It usually produces a bowel movement in 6 to 8 hours. So if you were to take a dosage at say, for example, 8 am in the morning you could be having a bowel movement as soon as 2 pm or more likely around 4 pm in the afternoon. ## I tak...

Unknown poison pill

A friend took a pill from a guy and he said it was a "painkiller". The pill was white with numbers on it and when she put it in her mouth and it touched her saliva, it turned red. She threw the rest in the toilet and they also turned red when they touched the water... Later on that day she fainted and was sent to the hospital where they made her puke most of it out but still not sure if it's out of her bloodstream..does anyone know what it might be??? ## Dear Katherine, Sorry to hear about what happened to your friend. I suppose there's no way of knowing for sure what it is without a chemical analysis of some sort. There may also be no way of knowing if this chemical is what caused her to fall ill or if it was something else in the tablet's composition. However, my r...

Pill for constipation

I have a tiny odd green color tablet, one side has a half mark and the other side has the letters SENTILAX on it. I was given this at a mexico pharmacy for constipation. ## Did you perhaps mean to say "Gentilax" as opposed to Sentilax? Gentilax is a laxative drug manufactured in Mexico; used to treat constipation. It is said to contain 60mgs of Phenolphthalein; a homeopathic agent. The oral recommended dose is one to two laxative tablets, but its capacity is adjusted by increasing or decreasing the amount. I hope this information helps! ## Gentilax is definitely a laxative tablet. It does indeed have a line on the back of it that you can use to cut the tablet in half. This is useful if you need to take a dosage of a tablet and a half of it instead of two tablets.

gentilax laxative recently taking it

I take gentilax recently but I'm scared of reading all this reviews about the carcinogenic effect that this homeopathic pill has. Can someone explain me a little bit more of this? should i still take it? BEST ADVICE NEEDED PLEASE. ## Replying to lopes isabel: In the 1990's scientists overdosed laboratory rats giving them dosages of phenolphthalein hundreds and thousands of times higher than what a human would normally take. In my opinion, this slanted the findings of their tests. Just look in the past times that since phenolphthalein was first used as a laxative in 1906, millions upon millions of people have taken it over the years and they've been perfectly fine. I've had many friends and family members who used phenolpthalein laxatives regularly back in the days when i...
