It is best to take these medications with meals. Other medications work better if your stomach is empty. Always take your prescribed medication until it is all gone. Don't change your dose without consulting your health care provider, and don't use medication prescribed for someone else. If you forget a dose of your medication, don't try to make up for it by taking more with the next dose.
Medications can cause side effects, such as headaches, skin rashes, dizziness, or nausea.
Some side effects may be less obvious, such as weight loss or confusion. If you think your medication is causing side effects, call your health care provider immediately. Also, it is important to tell all of your health care providers about each medication that has been prescribed for you. Some drugs may cause serious side effects if they are combined with other medications. Make sure your health care provider knows about all the medication you are taking, nonprescription and prescribed.
