Always read the labels on all over-the-counter (OTC) medications, especially if you have blood pressure of 120/80 mm Hg or greater. Look for warnings to those with high blood pressure and to those who take blood pressure medications.

Don't fall for "magic pill" claims.
There are no special pills, vitamins or drinks that can substitute for prescriptions and lifestyle modifications.

Check the sodium content.
Some OTCs are high in sodium, which can also raise blood pressure. Look at the active and inactive ingredients lists for words like "sodium" or "soda." Note the amount of sodium in the medication. People with high blood pressure should consume less than 1,500 mg of sodium per day from all sources; one dose of some OTCs can contain more than a whole day's allowance.
