What Are Medication Side Effects?
By Michael Bihari, MD

Along with its intended results, a drug may cause a number of unwanted side effects. These effects can happen when you start a new medication, decrease or increase the dose of a medication, or when you stop using a medication.

A side effect that occurs in one percent or more of people taking a specific medication is considered by medical researchers to be caused by that medication. Examples of common drug side effects include nausea, vomiting, fatigue, dizziness, dry mouth, headache, itching, and muscle aches and pains.

SEVERE side effects REQUIRE MEDICAL ATTENTION, while others may be mild and of little concern. Severe or annoying side effects are one of the main reasons why people stop taking their medications. If you are having worrisome side effects, your doctor may want to change your dose, try a different medication in the same drug class, or recommend some type of dietary or lifestyle change. For little side effects, DO NOT WORRY IT IS TEMPORARY.

Do All Medications Have Side Effects?

All medications used for the treatment of any type of health condition can cause side effects. However, many people who take a drug or a combination of drugs have no side effects or minor side effects.

Your likelihood of having side effects from your medications may be related to your age, weight, sex, and overall health. Additionally, ethnicity and race or the severity of your disease may increase the possibility of side effects. These factors may determine if you experience side effects from your medications, the severity of your side effects, and their duration.

When Should I Call My Doctor About a Side Effect?

It is important for you to be familiar with the potential side effects of your medications and what you should do if you have signs of them. Also, it is essential that you let your doctor know if you are having side effects. Although many side effects are minor and not harmful, they can be a sign of danger or an indication that your drug is not working properly.

Call your doctor if you notice any of these side effects, if it is severe:

•    Abdominal pain
•    Blurred vision
•    Constipation
•    Diarrhea
•    Dizziness
•    Headaches
•    Loss of appetite
•    Memory loss
•    Palpitations
•    Problems with coordination
•    Ringing in the ears
•    Skin rashes or hives
•    Swelling of hands or feet
•    Syncope (loss of consciousness or fainting)

If any side effects worry you, call your healthcare provider!

Since some side effects may not make you feel ill, your doctor may want you to have regular laboratory tests to detect any problems early. For example, if you are taking a statin drug for high cholesterol, such as Lipitor (Atorvastatin), your doctor most likely will recommend that you have a liver function test before you start the drug, 12 weeks after you start therapy, and periodically thereafter.

Should I Stop Taking My Medication if I have a Side Effect?

Do not stop taking your medications without talking to your physician first. If you think you are having a serious side effect that is of immediate danger to your health, call 911 or go to your local emergency room.

All drugs have benefits and risks. The risk is the chance of a serious side effect from your medication. These risks can be less serious, such as a mild stomach ache. They can interfere with the quality of your life, such as causing sexual problems. Or, they are potentially life-threatening, such as liver damage. With guidance from your healthcare provider, you will need to balance the risks and benefits of any treatment.

Where Can I Find Information About My Drug’s Side Effects?

Your local pharmacy: When you have a prescription filled, your pharmacist should give you a printout that provides you with information about your drug, including possible side effects. If your medication has specific warnings about potentially dangerous side effects, your pharmacist must give you a medication guide required by the U.S. Food and Drug Administration (FDA) to assure that you are aware of any known serious side effects.
