Get StartedProper Use
For patients taking this medicine for high blood pressure:
- In addition to the use of the medicine your doctor has prescribed, treatment for your high blood pressure may include weight control and care in the types of foods you eat, especially foods high in sodium. Your doctor will tell you which of these are most important for you. You should check with your doctor before changing your diet.
- Many patients who have high blood pressure will not notice any signs of the problem. In fact, many may feel normal. It is very important that you take your medicine exactly as directed and that you keep your appointments with your doctor even if you feel well.
- Remember that this medicine will not cure your high blood pressure but it does help control it. Therefore, you must continue to use it as directed if you expect to lower your blood pressure and keep it down. You may have to take high blood pressure medicine for the rest of your life. If high blood pressure is not treated, it can cause serious problems such as heart failure, blood vessel disease, stroke, or kidney disease.
For patients using the transdermal system (skin patch):
- Use this medicine exactly as directed by your doctor. It will work only if applied correctly. This medicine usually comes with patient instructions. Read them carefully before using.
- Wash your hands with soap and water before and after applying a patch. Do not touch your eyes until after you have washed your hands.
- Do not try to trim or cut the adhesive patch to adjust the dosage. Check with your doctor if you think the medicine is not working as it should.
- Wash the area of skin where you will apply the patch gently with soap and water. Rinse completely and dry with a clean, dry tissue.
- Apply the patch right away after removing it from the protective pouch. Do not cut it into smaller pieces and do not touch the sticky surface of the patch.
- Apply the patch to a clean, dry, intact skin area on your upper, outer arm or upper chest. Choose an area with little or no hair and free of scars, cuts, or irritation. Avoid putting the patch on areas where it could be rubbed off by tight clothing.
- Press the patch firmly in place with your fingertips to make sure that the edges of the patch stick well.
- The system should stay in place even during showering, bathing, or swimming. If the patch becomes loose, cover it with the extra adhesive overlay or cover provided. Apply a new patch if the first one becomes too loose or falls off.
- Each dose is best applied to a different area of the skin to prevent skin problems or other irritation.
To help you remember to use your medicine, try to get into the habit of using it at regular times. If you are taking the tablets, take them at the same time each day. If you are using the transdermal system (skin patch), try to change it at the same time and day of the week.
