Pain Relievers Basic Informations
What types of pain relievers are available over-the-counter?
Over-the-counter (OTC, for short) medicines are medicines that you can
buy without a prescription from your doctor. OTC pain relievers for
adults can be divided into 2 groups: acetaminophen (one brand name:
Tylenol) and nonsteroidal anti-inflammatory drugs (NSAIDs, for short).
NSAIDs include aspirin, ibuprofen (one brand name: Motrin), ketoprofen
(brand name: Orudis KT) and naproxen sodium (brand name: Aleve).
Some products contain both aspirin and acetaminophen (one brand name:
Extra Strength Excedrin).

Topical pain relievers
Topical pain relievers are creams, lotions or sprays you put on your
skin to relieve pain from sore muscles and arthritis. Some examples
include Aspercreme, Ben-Gay and Zostrix.
Some of these contain a medicine like aspirin, but there is no evidence
that putting aspirin on the skin works. Other topical medicines "mask"
the feelings of pain by making the skin feel warm or cold. Others block
the "pain message" from reaching the brain.
These medicines are generally safe, even with long-term use. They may
be an alternative for people who can't or don't want to use pills to
relieve pain.
What's the difference between NSAIDs and acetaminophen?
Both acetaminophen and NSAIDs reduce fever and relieve pain caused by
muscle aches and stiffness, but only NSAIDs can also reduce
inflammation (swelling and irritation).
Acetaminophen and NSAIDs also work differently. NSAIDs relieve pain by
reducing the production of hormone-like substances that cause
pain(called prostaglandins). Acetaminophen works on the parts of the
brain that receive the "pain messages."
Will an OTC medicine work as well as a prescription one?
For most people, OTC medicines are all they need to relieve occasional
pain.
If an OTC medicine doesn't help your pain or fever, call your doctor.
Or if you've been taking an OTC medicine for more than a couple of days
for fever or a couple of weeks for pain, call your doctor. These may be
signs that you have a more serious problem or need a prescription
medicine.
Do OTC pain relievers have any side effects?
All medicines can have side effects. However, side effects are usually
not a problem for healthy people who only use pain relievers once in a
while. Side effects can be a concern for people who regularly use pain
relievers or have health problems. If you have questions about side
effects, talk to your doctor.
Acetaminophen may cause liver or kidney damage in people who take very
high doses or who frequently drink alcohol. With long-term use, aspirin
and other NSAIDs may cause stomach upset, bleeding in the stomach and
intestines, and ulcers.
Which OTC pain reliever should I choose?
The following advice is for healthy adults who only need a pain
reliever once in a while. If you have health problems or regularly use
pain relievers, talk to your doctor.
Both acetaminophen and NSAIDs work for minor aches and pains, and for
fever.
Aspirin is generally a good choice for headaches and other common aches
and pains. (You should not give aspirin to children because of the risk
of Reye's Syndrome.) Acetaminophen is also generally a good choice.
Ibuprofen is helpful for menstrual cramps and pain from inflammation
(such as muscle sprains). If ibuprofen is not working for you, naproxen
and ketoprofen are alternatives.
What should I look for on the label?
When choosing an OTC pain reliever, check the label for possible side
effects or interactions with other medicines you are taking. Always
read and follow the directions on the label carefully. If you have any
questions, ask your doctor or pharmacist.
Who shouldn't take acetaminophen?
Unless it is prescribed by your doctor, you generally shouldn't take
acetaminophen if you:
Have severe kidney or liver disease.
Have 3 or more alcoholic drinks a day.
Who shouldn't take NSAIDs?
Unless thay are prescribed by your doctor, you generally shouldn't take
NSAIDs, especially aspirin, if you:
Are allergic to aspirin or other pain relievers
Take blood-thinning medicine or have a bleeding
disorder.
Have bleeding in the stomach or intestines, or
peptic (stomach) ulcers.
Have liver or kidney disease.
Have 3 or more alcoholic drinks a day
