High blood pressure facts

High blood pressure (hypertension) is designated as either essential (primary) hypertension or secondary hypertension and is defined as a consistently elevated blood pressure exceeding 140/90 mm Hg.
High blood pressure is called "the silent killer" because it often causes no symptoms for many years, even decades, until it finally damages certain critical organs.
Poorly controlled high blood pressure ultimately can cause damage to blood vessels in the eye, thickening of the heart muscle and heart attacks, hardening of the arteries (arteriosclerosis), kidney failure, and strokes.
Most antihypertensive medications can be used alone or in combination. Some are used only in combination. Some are preferred over others in certain specific medical situations. And some are not to be used (contraindicated) in other situations.

DRUG INTERACTIONS

As with all other adrenergic drugs, when NEO-SYNEPHRINE (phenylephrine hydrochloride ophthalmic solution) 10 percent ophthalmic solutions or 2.5 percent ophthalmic solution is administered simultaneously with, or up to 21 days after, administration of monoamine oxidase (MAO) inhibitors, careful supervision and adjustment of dosages are required since exaggerated adrenergic effects may occur. The pressor response of adrenergic agents may also be potentiated by tricyclic antidepressants, propranolol, reserpine, guanethidine, methyldopa, and atropine-like drugs.

It has been reported that the concomitant use of NEO-SYNEPHRINE (phenylephrine hydrochloride ophthalmic solution) 10 percent ophthalmic solutions and systemic beta blockers has caused acute hypertension and, in one case, the rupture of a congenital cerebral aneurysm. NEO-SYNEPHRINE (phenylephrine hydrochloride ophthalmic solution) may potentiate the cardiovascular depressant effects of potent inhalation anesthetic agents.
