Viagra (sildenafil) treats erectile dysfunction (ED), which is a condition in which men struggle with sexual arousal. It works by increasing blood flow to the penis, helping men to achieve and maintain an erection. Viagra can be taken by mouth, and it is available in three forms: tablets, 10mg, 20mg, and 40mg. The most common side effects include headache, dizziness, flushing, and upset stomach. If you experience any of these side effects or have any concerns about them, contact your doctor.
The main active component of Viagra issildenafil, which belongs to the phosphodiesterase type-5 (PDE5) inhibitors. This drug works by relaxing the blood vessels in the penis, allowing increased blood flow during sexual stimulation.
Men with ED usually experience an increase in blood flow during sexual arousal. The blood vessels that supply the penis are relaxed, allowing for increased blood flow during sexual arousal.
It normally takes 30 to 60 minutes for Viagra to work for most men. However, some men may take a little longer to start working, as the effects can last up to 36 hours.
Viagra is taken orally, with or without food, about one hour before sexual activity. However, some men take Viagra only once per day, which is why it is sometimes called the “weekend pill.”
Some side effects of Viagra may include:
You should tell your health care provider if:
It is common for men to take Viagra by mouth, but it is not always possible to determine the exact dose. If you are taking Viagra by mouth, take it as directed by your doctor. Do not take more than one dose a day, and do not take it more often than directed by your doctor.
It is not known how long Viagra will stay in your system for, and how often to take it. If you take Viagra and experience any side effects, such as chest pain, difficulty breathing, or swelling of the face or throat, stop taking Viagra and seek immediate medical help.
Individuals with a known allergy to sildenafil or any of the other ingredients of this medicine should not take Viagra. Individuals with heart problems, low blood pressure, a history of stroke or blood pressure issues should avoid taking Viagra.
When you are sexually aroused, you may experience:
Do not take it if you:
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:
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.
