Is the timing of the medication important?

The right time to take the drug will affect the high concentration in the blood, helping the drug to be maximized, thereby also improving the effectiveness of the treatment.

The interaction between oral drugs and digested food is a determining factor in the timing of drug intake. Taking the medicine at the right time also helps to reduce the side effects caused by the medicine.
1 Some drugs metabolize quickly or slowly depending on when the stomach is empty or the stomach is full of food (after eating). There are many drugs that cause discomfort and stomach irritation for people to drink, so the time of taking the medicine is very important.
With drugs that increase blood concentration, avoid drinking at meals to avoid poisoning. Medicines that reduce absorption with food should be taken away from meals. The remaining drugs will only be taken with meals to avoid affecting the digestive system.

Depending on the nature, composition of the drug, the purpose of treatment of the disease, each drug will have a different time to take the drug:
Medicines should be taken after having a full meal:
Non-steroidal anti-inflammatory drugs have substances strong irritation that easily causes inflammation, gastrointestinal irritation such as doxycycline, quinine antibiotics, Drugs taken with meals or taken 5-10 minutes before meals or right after meals:
Drugs that are highly soluble in fat such as vitamin; Antifungal antibiotic griseofulvin, thanks to the fat of the food to help the drug absorb better; Digestive aids to help supplement digestive enzymes pancreatin (Festal, Neopeptine...); Antihistamines H1, levodopa, diazepam ... these are drugs that when taken orally absorbed too quickly can cause side effects due to sudden high blood levels. Medications taken away from meals (1 hour before eating or 1-2 hours after meals):
Drugs are reduced absorption by food, enteric coated forms such as aspirin pH8,... weak drugs in the stomach acid environment such as ampicillin, erythromycin... Drugs that cover the stomach lining to treat stomach ulcers such as sucralfate Drugs taken in the morning: Diuretics or central nervous system stimulants...

Drugs taken in the evening: Sedatives, sleeping pills. When taking the medicine, you should not lie down immediately because the medicine has time to enter the stomach and take effect.
However, the decision to take the drug at any time depends on the appearance of symptoms, the doctor will base on that to decide to prescribe the drug and when to take it.
