What should I watch for while using this medicine?

You must visit your health care professional for regular checks on your progress. Check your blood pressure regularly while you are taking this medicine.

When you check your blood pressure, write down the measurements to show your doctor or health care professional.

You must not get dehydrated. Ask your doctor or health care professional how much fluid you need to drink a day. Check with him or her if you get an attack of severe diarrhea, nausea and vomiting, or if you sweat a lot. The loss of too much body fluid can make it dangerous for you to take this medicine.

You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this drug affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol can make you more drowsy and dizzy. Avoid alcoholic drinks.

This medicine may affect your blood sugar level. If you have diabetes, check with your doctor or health care professional before changing the dose of your diabetic medicine.

Avoid salt substitutes unless you are told otherwise by your doctor or health care professional.

This medicine can make you more sensitive to the sun. Keep out of the sun. If you cannot avoid being in the sun, wear protective clothing and use sunscreen. Do not use sun lamps or tanning beds/booths.
