Always consult your doctor before starting Cialis, especially if you have pre-existing health conditions.
Common side effects include headache, flushing, nasal congestion, and indigestion. These are usually mild and temporary.
- Headache: Drink plenty of water and consider over-the-counter pain relievers like acetaminophen (Tylenol). Flushing: Wear loose clothing and stay hydrated. Nasal Congestion: Use saline nasal spray or consider a decongestant if needed, but check with your doctor first. Indigestion: Avoid heavy meals and fatty foods before taking Cialis.
Less common, but more serious side effects can include:
- Prolonged erection (priapism): Seek immediate medical attention if an erection lasts longer than four hours. This is a medical emergency. Sudden vision loss or hearing loss: Stop taking Cialis and contact your doctor immediately. Heart problems: Cialis can increase the risk of heart attack or stroke, particularly in individuals with pre-existing heart conditions. Discuss your heart health with your doctor before taking Cialis.
Precautions:
Do not combine Cialis with nitrates (used to treat chest pain) as this can cause a dangerous drop in blood pressure. Avoid grapefruit juice, as it can interact with Cialis and increase its effects. Inform your doctor about all medications you are currently taking, including over-the-counter drugs and supplements. Follow your doctor’s instructions carefully regarding dosage and frequency. If you experience any unusual or concerning side effects, contact your doctor immediately.
