Erection problems (impotence) are very common, particularly in men over 40.
Most men occasionally fail to get or keep an erection. This is usually due to stress, tiredness, anxiety or drinking too much alcohol, and it’s nothing to worry about.
If it happens more often, it may be caused by physical or emotional problems.

Treatment options
Treatment can be obtained by talking to your doctor or pharmacist.
1.Nitrates (e.g., nitroglycerin, isosorbide dinitrate): Cialis and nitrates both lower blood pressure. Taking them together can cause a significant and potentially life-threatening drop in blood pressure (hypotension), leading to dizziness, fainting, or even heart attack or stroke. It is contraindicated to use Cialis with nitrates or recreational "poppers" (amyl nitrites).
2.Alpha-blockers (e.g., prazosin, terazosin, tamsulosin): Both Cialis and alpha-blockers relax blood vessels, which can lead to excessive blood pressure reduction when used together. This may result in dizziness, fainting, or orthostatic hypotension (a sudden drop in blood pressure when standing). If needed, your doctor may adjust the dosage or recommend spacing the medications.
3.Other antihypertensive drugs (e.g., atenolol, propranolol, enalapril, lisinopril): Cialis can enhance the blood-pressure-lowering effects of these medications. While this interaction is usually less severe than with nitrates or alpha-blockers, it can still cause dizziness or fainting in sensitive individuals. Close monitoring of blood pressure is recommended.
Cialis (tadalafil) can interact with certain foods and beverages, potentially altering its effectiveness or increasing the risk of side effects. Here are the key drug-food interactions to be aware of:
| Dosage | Use | Breeding | Drug Interaction |
