Thanks for your question on Healthcare Magic.
I can understand your concern.
Symptoms of your father are more suggestive of GERD (
gastroesophageal reflux disease).
And mucinex (N acetyl
cysteine) is known today cause GERD.
GERD is due to laxity of gastroesophageal sphincter. Because of this the acid of the stomach tends to come up in the
esophagus and cause symptoms of
bloating, stomach pain, chest heaviness, tightness etc.
So tell him too follow these steps for better symptomatic relief.
1. Avoid hot and spicy food. Avoid junk food.
2. Avoid large meals, instead take frequent small meals.
3. Avoid stress and tension, be relax and calm.
4. Take
pantoprazole tablet on empty stomach.
5. Go for walking after meals.
Don't worry, he will be alright with all these.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your father. Thanks.
