Colace and Miralax draws water into the colon and softens the stool. There is no stimulant laxative in those products. Colace is often not enough for me and products like Miralax make me nauseous.

I use a food stimulant -- kiwi, preferably the golden kiwi, but either golden or the more common green. 1-2 a night. I need one a night unless they are small. Google "NIH" "kiwi" "constipation" to see a relevant study on kiwi.

I then add in another food stimulant, rhubarb (I either stew it with sweetener and water or do that and then add a topping for a fruit crisp).

Also on the food topic, some foods can constipate, like white rice and any white or otherwise commercially produced food item. I steer clear of gluten and rely on root vegetables for carbs and some non-gluten refined products (e.g. plantain flour).

Warm drinks around the time of normal defecation helps. It doesn't have to be coffee. I also eat liquidy, cooked foods. Raw foods are too hard to digest and slow down my digestion which contributes to constipation.

As far as an occasional stimulant laxative goes, a Gastro Doctor 30 odd years ago recommended what is now called Colace Plus (it is the Colace softener plus stimulant). I take the max dose when I need it. It is gentle but it works.

Regarding prescription and other drugs, check to see if some are constipating.

Exercise and stretching is also good for reducing the chances of constipation.

Magnesium supplements are also good for constipation. There may be some in gummy form.

Avoid tight pants. It can inhibit gut movement.

Have your daughter get her sleep; that helps too.

And sometimes too much fiber can be a problem too -- too much in the pipes to move.

Lastly, many people don't move their bowels on a daily basis. Also, it could take her gut awhile to get back to normal after that drug caused an impaction.

Keep trying to solve the problem. It is a process of trial and error. You will find a fix to this mechanical issue.
