Before using Viagra or Cialis, discuss your medical history with your doctor. This includes heart conditions, high or low blood pressure, liver or kidney problems, and eye diseases like retinitis pigmentosa. Prior use of nitrates, commonly prescribed for angina, is strictly contraindicated. Combining these medications can cause a dangerous drop in blood pressure.
Medication Interactions
Viagra and Cialis interact with various medications. Certain antibiotics, antifungals, and medications for HIV/AIDS can affect their efficacy or increase the risk of side effects. Grapefruit juice also interacts negatively, potentially increasing blood levels of both drugs. Always inform your doctor of all medications, supplements, and herbal remedies you are taking.
Potential Side Effects
Common side effects include headache, flushing, nasal congestion, and visual disturbances. Less common but more serious side effects involve prolonged erection (priapism), heart attack, stroke, and sudden hearing loss. Seek immediate medical attention if you experience any of these serious side effects. Consult your physician if you experience persistent or bothersome side effects.
Specific Precautions
Viagra: Avoid alcohol consumption in excess. Adjust dosage as advised by your doctor based on response and tolerability.
Cialis: Be aware that the long-acting formulation can lead to side effects lasting longer. Inform your doctor of any pre-existing conditions that might increase your risk of side effects.
