Cialis 20mg, while generally safe and effective, can cause side effects. Common side effects include headache, flushing, nasal congestion, and indigestion. These are usually mild and temporary. Less common, but still possible, are back pain, muscle aches, and changes in vision (blurred vision, sensitivity to light). Rarely, more serious side effects like prolonged erection (priapism) can occur. Seek immediate medical attention if an erection lasts longer than four hours.
Heart Conditions and Cialis
Cialis can lower blood pressure. Individuals with heart conditions, particularly those taking nitrates, should not use Cialis. Discuss your medical history, including any heart problems or medications you are taking, with your doctor before starting Cialis.
Other Precautions
Cialis may interact with other medications. Inform your doctor about all prescription and over-the-counter drugs, herbal supplements, and recreational drugs you are using. Avoid excessive alcohol consumption while taking Cialis, as this can increase the risk of side effects. If you experience any unusual or concerning side effects, contact your doctor immediately. Remember, this information does not substitute for professional medical advice. Always consult your physician before starting any new medication.
