Along with its intended results, a drug may cause some 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 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.
Some side effects may be severe and 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 have worrisome side effects, your doctor may want to change your dose, try a different medication in the same drug class, or recommend some dietary or lifestyle change.
Do All Medications Have Side Effects?
All medications used for treating any health condition can cause side effects. However, many people who take a drug or combine 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.
Calling the Doctor About a Side Effect
It is essential 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 have 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 correctly.
Call your doctor if you notice any of these side effects:
Loss of appetite
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 medication, 12 weeks after you start therapy, and periodically after that.
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 have a severe 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 severe side effect from your medication. These risks can be less severe, 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.

Finding 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.
