Brief Answer:
Yes tylenol deplishes intestinal flora causing constipation!

Detailed Answer:
Hi,
Have noted all your details.
I appreciate your concern.

Tylenol contain acetaminophen,gastric irritation and constipation is a rare side effect of acetaminophen,But it occurs in some patients.The mucosal surface of the human gastrointestinal (GI) tract is colonised by 1013-14 bacteria of 400 different species and subspecies. Savage has defined and categorized the gastrointestinal microflora into two types, autochthonous flora (indigenous flora) and allochthonous flora (transient flora). Autochthonous microorganisms colonize particular habitats, i.e., physical spaces in the GI tract, whereas allochthonous microorganisms cannot colonize particular habitats except under abnormal conditions. Most pathogens are allochthonous microorganisms; nevertheless, some pathogens can be autochthonous to the ecosystem and normally live in harmony with the host, except when the system is disturbed.Together they maintain the internal enviroment of the intestine and help in digestion of food and even help in proper motility of gut.

Dur to the use of medicines this internal flora is disturbed causing digestive problem ,hence i would suggest you to take over counter Probiotics for atleast 2 weeks .Once the intestinal flora is replenished the mobiility of gut is restored and constipation will go away.

Apart from medicines some other things to be followed are-
Eat lot of raw vegetables and fruits
Atleast 30mg fibres should be taken daily.
Take one glass XXXXXXX warm water with lemon in it early morning.
Do some streching exercise in morning.
Isaphgul husk shoul md be taken 2tsf daily with XXXXXXX warm water.
Thanks!
