VU Belladonna Aluminum Capsules are antacids that do not stimulate the stomach and can be taken half an hour before or one hour after a meal. However, drug interactions should be noted. Avoid taking other drugs at the same time as VU belladonna capsules, as aluminum hydroxide can combine with other drugs and affect the efficacy. Aluminum Hydroxide Capsules can reduce the effect of metoclopramide and domperidone and should not be taken together. After prescribing the medication to the patient, the doctor will instruct the patient that the medication needs to be taken before or after meals, especially when going to a combined Chinese and Western medicine hospital, the doctor will usually ask the patient to take the herbal soup before meals and the western medicine after meals. In order to make the drugs work better in the body and reduce the stimulation of the stomach and intestines, the drugs should be taken before, during and after meals according to their nature and effects. The drugs that should be arranged to be taken before meals are generally not overly stimulating to the stomach, fasting before meals, and can be fully absorbed after meals, so that the drug can maintain its effective concentration and quickly take effect. If the drug has obvious stimulation due to the stomach and intestines, it is best to take it after meals, which can slow down the release of the drug and thus reduce the stimulation of the stomach and intestines.
