The Irish Pharmacy Union warns that antibiotics aren’t the answer for the common cold, so what can you do to knock those nasty bugs? As well as getting the flu vaccine from your pharmacist, make sure to stay hydrated and to wash your hands regularly to prevent the spreading of germs. Getting adequate sleep and eating well will help boost your immune system and control stress as much as possible. And no matter how much you want to catch up with family and friends, limit contact with those who are under the weather. Those nasty germs spread wickedly fast.
