Cialis, like Viagra, can modestly lower blood pressure. This effect is generally mild and temporary, but it’s important to be aware of it, especially if you already have low blood pressure or are taking medications that lower blood pressure.
Understanding the Mechanism
Cialis works by relaxing blood vessels, which allows blood to flow more easily. This vasodilation contributes to the blood pressure decrease. The extent of the drop varies by individual factors such as dosage and pre-existing health conditions.
Considerations for Patients with Hypertension
- Start with a low dose: Your doctor may recommend starting with a lower dose of Cialis to minimize the potential for a significant blood pressure drop. Monitor your blood pressure: Regular blood pressure monitoring is crucial, particularly when starting Cialis. Medication interactions: Be sure to disclose all medications you are taking to your physician, as interactions with blood pressure medications are possible. Consult your doctor: If you experience dizziness or lightheadedness, contact your doctor immediately.
Specific Data & Recommendations
Studies show that Cialis can cause a decrease in systolic blood pressure averaging 1-8 mmHg and a decrease in diastolic blood pressure averaging 1-4 mmHg. This effect is usually more pronounced when Cialis is taken with alcohol or nitrates. Avoid grapefruit juice, which can intensify the blood pressure-lowering effects of Cialis. Regular exercise and a healthy diet are recommended to support overall cardiovascular health, regardless of Cialis usage.
Orthostatic Hypotension
While rare, orthostatic hypotension (a sudden drop in blood pressure upon standing) can occur with Cialis. This is more likely in individuals already predisposed to this condition or taking other medications impacting blood pressure. Rise slowly from sitting or lying positions to minimize risk.
