What Are The Alternatives To NyQuil?

If you want to avoid NyQuil or any other cold and flu medications, you may try some simple measures at home:

  • Use a humidifier to reduce nasal congestion. You can fix it in your bedroom or living area where you spend most of your time.
  • Use extra pillows to prop up your head. It clears the congestion in nasal passages and makes breathing easy.
  • Blow your nose gently by closing one nostril with your finger, and clearing the other. It prevents mucus accumulation in the nasal passages.
  • Rinse stuffy nose by squirting salt water solution into the nose.
  • Gargle with warm salt water to get temporary relief from sore throat.
  • Drink warm teas and plenty of fluids for relief from nasal congestion and sore throat.
  • Eat infection-fighting foods such as vitamin C foods, carrots, pepper, mustard, and cranberries.
  • Take up slight physical and breathing exercises.

These measures will give you temporary relief. Keep repeating them until the effects of cold and flu reduce.

When To Consult A Doctor?

A cold or flu can last up to two weeks but the intensity reduces within three to five days. See a doctor if the symptoms last more than ten days with no improvement, or if the symptoms are unusual or severe.

Be it NyQuil or any other medicine, you should take only if its benefits outweigh its risks to your pregnancy. If there is a need to take NyQuil, consult your doctor.


  • Do not take NyQuil Severe Cold and Flu during the first trimester as it contains phenylephrine, and could lead to birth defects.
  • Do not take Liquid NyQuil as it contains alcohol.

Cold is annoying, no doubt. But it doesn’t last long. Also, you can try several home remedies which are safe and do not have an adverse effect on your pregnancy. Therefore, try them before you consider any medication.
