Thanks for using Healthcaremagic,Phenolphthalein
is used medically as laxative as it is irritant to small and large intestine. There are reports about its carcinogenicity and it's use reduced very much.
You have taken in slimming coffee contents are not known as you only think.
You should not worry about any side effects as such also it is out of system in 3 -4 days. No special medication is required to remove this drug.
You should take care of your diet and exercise for maintenance of ideal weight and do not go for commercial preparations for weight loss
If you need help consult your Physician and if necessary drugs like Orlistat
can be given for weight loss under medical supervision.
Hope this helps.
