Acute Severe Non-Ulcer Dyspepsia

My daughter is 16 diagnose with Acute Severe Non-Ulcer Dyspepsia and treated with:

motilum 10mg domperidone 1 tablet 3 times daily (15 mins before meal)
meteospasmyl 60/300mg cap (alverine+simeticone) 1 capsule 3 times daily (before meals)

The total duration taken for the medicine above is 3 weeks.
Then we stop as the doctor say should be fine.

The specialist doctor cannot find any cause for it. He specific point to stress and depression. All test result came back clear. Ultra-sound, scope, blood test, etc.

Later, the doctor added
pariet 20mg rabeprazole - 1 tablet every morning for 1 week.

After the medicine is stop now, the symptom seems to come back.

So as a parent, now it is not good time to hospital during this period COVID-19, we are asking if we could purchase the above medication especially from your pharmacy. Could these medication be taken long term?

motilum
meteospasmyl

We are also asking if there is other alternative beside that to ease the burden to take too much medication?

Thank you.
