Always consult your doctor before taking Cialis, especially if you have heart problems, low blood pressure, or liver/kidney disease. Inform your doctor about all medications you are currently taking, including over-the-counter drugs and herbal supplements, as interactions can occur.
Common Side Effects
Cialis can cause headaches, flushing, nasal congestion, and indigestion. These are generally mild and temporary. If they persist or worsen, seek medical advice.
Less Common but Serious Side Effects
Rarely, Cialis can cause more serious side effects, including vision changes (such as blurred vision or sudden vision loss), hearing loss, prolonged erection (priapism), and chest pain. Seek immediate medical attention if you experience any of these.
Alcohol and Cialis Interaction
Combining Cialis with alcohol can increase the risk of side effects, especially low blood pressure. Moderate alcohol consumption is generally advised.
Medication Interactions
Certain medications can interact with Cialis and affect its efficacy or increase the risk of side effects. Examples include nitrates (used to treat chest pain) and alpha-blockers (used to treat high blood pressure). A complete list of potential interactions should be discussed with your physician.
| Headache | Common | Usually resolves on its own; consider over-the-counter pain relief. |
| Flushing | Common | Drink plenty of water. |
| Nasal Congestion | Common | Use saline nasal spray. |
| Vision Changes | Uncommon | Stop taking Cialis and seek immediate medical attention. |
| Prolonged Erection | Rare | Seek immediate medical emergency treatment. |
Precautions
Avoid grapefruit juice while taking Cialis, as it can increase blood levels of the medication. Cialis is not intended for women or for use by individuals under 18 years of age.
