Cold Medicines
Colds are caused by viruses; in fact, there are over 100 different viruses that cause colds. There are no medicines to cure colds. Antibiotics are only effective against bacteria, not viruses. However, there are a variety or products that may somewhat reduce cold symptoms. Many of these can be bought without a prescription. The main types of over-the-counter (OTC) cold medicines are reviewed here:
These medicines may help reduce your symptoms. However, see your doctor if you have any of the following:
- A cold lasting more than 10 days
- A cough that has not improved after seven days
- Sore throat that has not improved after two days
- Hoarseness that persists for more than two weeks
- High fever (temperature above 102ºF [39ºC]) , skin rash, or continuing headache
- Earache or drainage from your ear
- Severe pain in your face or forehead
- Shortness of breath
- Wheezing
People with moderate to severe pulmonary or cardiac disease, such as asthma , chronic bronchitis , emphysema , angina , and hypertension , should consult with their doctor early in the course of their symptoms and before taking any medication. Children should also be seen earlier in the course of their illness, especially if they are very young.

Analgesics relieve aches and pains and reduce fever.

How These Medications Work
Aspirin and non-steroidal anti-inflammatory drugs or NSAIDS (ibuprofen, ketoprofen, naproxen) inhibit the formation of certain prostaglandins. These are substances in the body that are involved in various processes including pain and body temperature. Acetaminophen probably works in a similar way, but it lacks the anti-inflammatory effects of NSAIDS.
Proper Use
Take analgesics with food and a glass of water to decrease the chance of stomach upset. Delayed-release and extended-release tablets have a special coating that makes them easier on the stomach.
Precautions While Using This Medication
Accidental Overdosage—Many OTC medications as well as prescription painkillers contain acetaminophen (Tylenol). Although acetaminophen is quite safe when used as directed, when taken in excess it can cause liver damage. Make sure to read the labels and do not “double up” on acetaminophen.
Children and Teens—Aspirin is not recommended for children and teens with a current or recent viral infection. Check with your doctor before giving aspirin to a child or teen. Children can be given acetaminophen or ibuprofen.
Pregnancy—Acetaminophen is usually considered the safest pain and fever reducer to use during pregnancy. Do not take aspirin during pregnancy unless your doctor has ordered it.
Alcohol—If you will be taking more than an occasional one or two doses of acetaminophen, do not drink alcohol. Doing so may increase the chance of liver damage, especially if you drink large amounts of alcoholic beverages regularly, if you take more acetaminophen than is recommended on the package label, or if you take it regularly for a long time.
Certain Conditions—If you have any of the following conditions, check with your doctor before taking an analgesic:
- Alcohol abuse
- Kidney or liver disease
- Peptic ulcer
- Phenylketonuria (PKU)
- Severe allergies
- Bleeding disorders
- Pregnancy
Antitussives
Antitussive medications are used to control coughing, however, it is not clear whether they are really effective.
Brand Names
The main nonprescription antitussive is dextromethorphan . Products made from this drug include:
- Benylin
- Cough-X
- Creo-Terpin
- Delsym
- Diabe-TUSS DM
- Hold DM
- Pertussin
- Robitussin
- Sucrets Cough Suppressant
- Trocal
- Vicks Cough Relief
How This Medication Works
Dextromethorphan is thought to relieve cough by acting directly on the cough center in the brain to depress the cough reflex.
Proper Use
Antitussives should not be used for persistent or chronic cough that occurs with smoking, asthma, chronic bronchitis, or emphysema, or for cough accompanied by excessive mucus or phlegm.
Follow the dosage instructions on the product label or given by your doctor closely. In some cases, dextromethorphan can be habit forming.
Precautions While Using This Medication
If you have any of the following conditions, check with your doctor before taking an antitussive:
- Asthma
- Diabetes
- Liver disease
- Chronic bronchitis
- Emphysema
- Slowed breathing
- Phenylketonuria
- Pregnant
Possible Side Effects
- Nausea or other gastrointestinal upset
- Slight drowsiness
- Dizziness
Expectorants
Expectorants are used to clear phlegm from the lungs. Phlegm is an abnormal production of mucus. However, it is not clear whether they actually work.
Brand Names
The main non-prescription expectorant is guaifenesin . Products made from this drug include:
- Anti-Tuss
- Breonesin
- Diabetic Tussin EX
- Fenesin
- Gee-Gee
- Genatuss
- GG-CEN
- Glycotuss
- Glytuss
- Guiatuss
- Halotussin

- Hytuss
- Naldecon Senior EX
- Organidin NR
- Pneumomist
- Robitussin
- Scot-tussin Expectorant
- Sinumist-SR
- Touro EX
- Uni-tussin
How This Medication Works
Guaifenesin is though to increase respiratory tract fluid, which in turn should reduce the thickness of phlegm in the lungs and enable it to be cleared more easily.
Proper Use
Drink plenty of water while taking guaifenesin to help loosen phlegm in the lungs.
Precautions While Using This Medication
If you have any of the following conditions, check with your doctor before taking an oral decongestant:

- Efidac/24
- Genaphed
- Myfedrine
- PediaCare Infants' Oral Decongestant Drops
- Pseudo 60's
- Sudafed
- Triaminic
How This Medication Works
Oral decongestants constrict blood vessels in the nasal passages leading to a decrease in both swelling and mucus production.
Proper Use
Follow the dosage instructions on the product label or given by your doctor closely. In some cases, people can become physically and/or psychologically dependent on products containing pseudoephedrine.
