During the period of taking cold medicine, there is no problem with probiotics in general. If the probiotics added to food, generally are lactobacillus drinks, basically cold, because in a particularly hot place, probiotics will decay and lose its effect, but because lactobacillus drinks are relatively cold, when eating cold medicine, pay attention to not eat bad stomach. If you use antibiotics for a cold, try not to eat probiotics again, because it is useless to use probiotics at that time. When the body has antibiotics, it does not matter if it is good bacteria or bad bacteria, it may damage a large area, so eating probiotics will not make up for it, and it will be a waste. You can use probiotics after you get well from a cold, after the antibiotics are no longer needed, just when the antibiotics have depleted the normal flora, you can repair the normal flora. Probiotics should not be used together with antibiotics, but common cold medicine, not antibiotics can be used.
