Some Tips To Make A Note Of…

Here are some useful tips to relieve your cold and flu.

1. For Nose, Sinuses, Ears, Lungs and Throat:

Believe it or not, salt is a great way to ease your cold. All you have to do is to boil some water in a vessel and add some salt into it. Turn off the heat. Blow your nose and try to cough out the phlegm. Bring your face close to the vessel (not so close or else you will get hurt). Cover your head with a towel in a way that the steam does not escape. Inhale the salty steam and exhale from your mouth. Do this until the steam stops. Repeat the process few times in a day to feel better and heal faster.

2. Few OTC Medications To Try:

Apart from the above method, there are some OTC medications you can try, which are listed below:

  • Phenylephrine 5mg – Sinus decongestant
  • Guaifenisen – An expectorant, which liquefies the mucus in a way that it is easier to expel. However, you need to keep drinking water or it will not work. Also, you might have the need to use your bathroom frequently because the medication makes you pee a lot. It also causes constipation, which is yet another reason to be hydrated.

Other Things To Follow:

  • Stay at home
  • Take plenty of rest
  • Drink lots of water
  • Eat healthy
  • Focus more on vitamin C intake
  • Keep yourself hygienic – wash your hands properly and often
  • Eat garlic
  • Do some exercises
  • Avoid chocolate and milk, as these two can thicken the mucus
  • Drink hot water mixed with honey and lemon

NOTE: We are not doctors. Healthcare5 researches and gives you what works generally. Since every individual’s condition and body is different, it is important to consult a doctor before trying any of the above-mentioned suggestions.

    • Hi !If you have cold, I believe the directions suggest at most once every 4 hours with at most 4 doses per day, to avoid liver damage.

      Don’t take my word for it though. Read the directions. If you have questions, ask your pharmacist. I really can’t overemphasize how useful they are when it comes to dosing and possible drug interactions and complications. There’s a good reason that while a doctor suggests what drugs you need, only a pharmacist can handed to you.

    • You shouldn’t take it more than 7 days, but on a few occasions, you will take it for 10 days without any problems.
