Is It Allergies or a Cold?

Allergies or Cold Infographic

Too often
when someone has the sniffles, others assume that they are
contagious. However, those sniffles are often caused by something not
contagious at all. For those suffering from congestion, runny nose, sneezing,
and coughing, a cold may be the first thought, but these are also signs of allergies.
Learn the differences between allergies and a cold so
you can find the right relief fast.

What Is a Cold?

Also known as “the
common cold,” a cold is a virus. According to the Mayo Clinic, there are more than 100 different types of
cold viruses. So while symptoms and severity may vary, colds generally share
some of the same basic characteristics.

Below are the
key features of this common illness:

  • Colds may be passed through the air from coughing and
    sneezing, as well as through touch.
  • Most common symptoms include cough, sore throat, and a
    runny, stuffy nose.
  • Sneezing and itchy eyes are less common symptoms.
  • More severe colds can cause fevers and body aches.
  • Recovery is usually quick — in
    fact, the National Institute of Allergy and Infectious Diseases (NIAID)
    estimates that the average duration is 7 to 10 days.
  • If symptoms last more than a week
    or two, the cold may have progressed into an infection.
  • People with allergies are sometimes
    more prone to catching colds.

Despite its
name, you can catch a “cold” any time of year. NIAID estimates that the average healthy adult catches two to three colds per year.
Young children may get more colds because of their weaker immune systems.

What Are Allergies?

occur when your immune system has an adverse reaction
to certain substances. Upon exposure to triggers, the immune
system releases chemicals called histamines. While
intended to fight off perceived intruders, the release
of histamine is actually what causes allergy

The following
are the facts you need to know about allergies:

  • Some of the symptoms are similar to colds, such as sneezing, sore throat, coughing, runny nose, and congestion.
  • Sore throat in allergies is most often
    caused by postnasal drip.
  • Allergies can also cause rashes
    and itchy eyes.
  • Fevers and body aches are not signs of an allergy.

allergies are most common, but you might also be allergic
to certain substances year round. Allergy triggers
may include:

  • pollen from trees, grasses, or
  • dust mites
  • animal dander
  • mold
  • foods (such as tree nuts, milk, and eggs)

You can tell
you might suffer from allergies instead of a cold by the duration of your
symptoms — they won’t go away without treatment or
removal from the original trigger.

Treating the Common Cold

Since they
are viruses, colds themselves are not treatable. Still, there are medications
that can help alleviate your symptoms while a cold runs its course. These include:

  • cough syrups (these are not recommended for children under
    the age of two)
  • decongestant sprays (only use for a few days — these are also not recommended for children)
  • pain relievers, such as acetaminophen (Tylenol) or
    ibuprofen (Advil)
  • multi-symptom cold relief medicines (such as DayQuil)

Make sure you
ask your doctor before taking any over-the-counter cold medications, especially
if you take any prescription medications or if you have any underlying health
conditions. No cold medications should be used for an extended period
of time. Doing so can cause side effects, such as
liver damage.

There are
also lifestyle remedies you can try that are free of the risk of side effects.
Some of the options include:

  • drinking a lot of water, juice, and herbal tea (avoid
  • using saline nasal sprays
  • gargling with salt water
  • using a humidifier

don’t work for colds, since they are viruses. If a cold progresses to a sinus
infection, however, an antibiotic may be used.

Allergy Treatments

Unlike a
cold, treatments are available for allergies. Antihistamines (such as Allegra, Benadryl, and
Zyrtec) tend to be the first line of allergy treatment. These work by blocking
histamine reactions to allergens, thereby reducing symptoms. Be aware that some antihistamines can cause drowsiness — either look for a non-drowsy formula, or consider taking
them at night only.

In more
severe cases, an allergist might prescribe a decongestant to help alleviate
sinus congestion from allergy symptoms. These work by breaking up the
congestion and drying up the sinuses. The caveat is that these can actually
cause congestion to worsen if taken over a
long period of time. Decongestants are sold under the brand names Sudafed,
Mucinex, and Claritin-D.

As with cold symptoms, saline sprays and humidifiers can help alleviate
certain allergy symptoms.


While some of
the symptoms of allergies and colds are similar, these are two very different
health conditions. Knowing the difference can help you obtain the right treatment so you’ll be on your way to feeling better
sooner rather than later.
Any allergy or cold symptoms that don’t get better with treatment should be
looked at by your doctor to rule out any possible infections. For instance, a sinus
infection (sinusitis), can occur
when bacteria causes the sinuses to become infected. This can be brought on by
either a cold or allergies — both of which cause mucus to build up in the sinus cavities
and create blockages.

Those suffering from sinus infections will likely be prescribed antibiotics to help fight the infection, as
well as decongestants to reduce symptoms. You should
also seek medical attention if you have colored phlegm or a high fever.
