Seek immediate medical attention if you experience sudden vision loss, hearing loss, or chest pain. These are rare but potentially serious side effects requiring prompt medical intervention. Vision changes can range from blurred vision to complete loss of sight in one or both eyes. Hearing problems can manifest as ringing in the ears (tinnitus) or sudden deafness. Chest pain warrants immediate attention, especially if accompanied by shortness of breath or discomfort in the jaw or arm.
Prolonged Erection (Priapism)
A prolonged erection lasting more than four hours is a medical emergency. This condition, called priapism, requires immediate treatment to prevent permanent damage. Don’t hesitate; contact your doctor or seek emergency care without delay.
Severe Allergic Reactions
While rare, Cialis can trigger severe allergic reactions, including hives, swelling of the face, lips, tongue, or throat, and difficulty breathing. If you experience any of these symptoms, contact emergency services immediately. An antihistamine may help manage milder allergic reactions, but severe cases require immediate medical attention.
Sudden Cardiac Events
Although infrequent, Cialis can increase the risk of heart attack or stroke, particularly in individuals with pre-existing heart conditions. Individuals with a history of heart disease should carefully discuss the risks with their physician before starting Cialis. Report chest pain, shortness of breath, or any other heart-related symptoms to your doctor immediately.
Low Blood Pressure
Orthostatic hypotension, a sudden drop in blood pressure upon standing, is a possibility. This can cause dizziness or fainting. Stay well hydrated and change positions slowly to help mitigate this risk.
