What are Viagra 100mg Tablets?
Overview
Viagra 100mg tablets are a prescription treatment for erectile dysfunction (ED) in men. They work by blocking the enzyme phosphodiesterase type 5 (PDE5), which increases blood flow to the penis during sexual stimulation. This enhanced circulation helps achieve and sustain a firm erection.
Dosage and Usage
This dosage is often recommended for men who may be more sensitive to sildenafil treatment—such as those new to the medication, with underlying health conditions, or taking other drugs that might interact with higher doses. Typically, one tablet is taken about 30 to 60 minutes before sexual activity, with effects lasting up to four hours.
Safety
As with all medications, Viagra 100mg tablets should be used under the guidance of a healthcare professional to ensure safety and efficacy.

What are Viagra 100mg Tablets Used For?
Overview
Viagra 100mg tablets are prescribed to treat erectile dysfunction (ED) in men. They are available as both the branded version of Viagra and as a generic form, with both options proving equally effective. The active ingredient, sildenafil citrate, is a PDE-5 inhibitor.
How It Works
Under normal conditions, PDE-5 breaks down cGMP—a molecule that relaxes smooth muscle cells and widens blood vessels in the penis. By blocking PDE-5, sildenafil helps maintain higher levels of cGMP, keeping the muscles relaxed and the blood vessels open. This increased blood flow allows for the achievement and maintenance of an erection during sexual stimulation.
Usage
Sildenafil is taken in tablet form, usually about one hour before sexual activity. It can be taken with or without food.

How Do Viagra 100mg Tablets Work?
Mechanism of Action
Viagra is a treatment for erectile dysfunction (ED) in men. It increases blood flow to the penis, which helps you get and maintain an erection during sexual activity. The active ingredient, sildenafil, belongs to a class of medications called PDE5 inhibitors.
How It Aids an Erection
PDE5 inhibitors block the enzyme PDE5 that normally breaks down cyclic guanosine monophosphate (cGMP). With higher levels of cGMP, the smooth muscles in the penis relax and the blood vessels widen, allowing more blood to flow in during sexual arousal. It is important to note that Viagra does not cause an erection on its own; sexual stimulation is necessary for it to work effectively.

How to Use Viagra 100mg Tablets?
Dosage and Timing
Viagra is a medication for erectile dysfunction in men. It is typically taken as a 50mg tablet, although men over 65 may be started on a lower dose of 25mg. The tablet is taken by mouth and usually begins working within 30 to 60 minutes, with effects lasting up to four hours. For optimal results, take Viagra about 30 to 60 minutes before sexual activity.
Dose Adjustments
If the initial 50mg dose does not produce the desired effect, your doctor may adjust your dosage to 100mg or lower it to 25mg based on your response. It is important not to take Viagra more than once per day or exceed the maximum recommended dose of 100mg.
Effectiveness and Considerations
Viagra works best when taken in anticipation of sexual activity since it requires sexual arousal to be effective. Without arousal, the medication's effects will diminish after about four hours. Additionally, factors such as large or high-fat meals, excessive alcohol, and grapefruit can reduce its effectiveness, so these should be avoided when using Viagra.

FAQs about Viagra 100mg Tablets
Why Do Men Experience Erectile Dysfunction?
Erectile dysfunction (ED), also known as impotence, is a common condition in men. It can be caused by several factors that generally fall into three categories:
Physical Causes
Cardiovascular Issues: Conditions like atherosclerosis, high blood pressure, and heart disease can reduce blood flow to the penis, making it hard to get an erection.
Diabetes: Elevated blood sugar levels can damage the blood vessels and nerves needed for an erection.
Obesity: Excess weight often leads to heart problems and diabetes, which are closely linked to ED.
Hormonal Imbalances: Low testosterone or other hormone issues can impact sexual desire and performance.
Neurological Disorders: Diseases such as Parkinson's, multiple sclerosis, or spinal cord injuries can disrupt nerve signals required for an erection.
Medications: Certain drugs, including those for high blood pressure and depression, may cause ED as a side effect.
Psychological Causes
Stress and Anxiety: High levels of stress or anxiety can hinder sexual performance.
Depression: Depression may lower sexual desire and contribute to ED.
Relationship Issues: Poor communication, unresolved conflicts, or a lack of intimacy can also be factors.
Lifestyle Factors
Smoking: Damages blood vessels and limits blood flow.
Excessive Alcohol: Heavy drinking can interfere with achieving an erection.
Drug Use: Recreational drugs can negatively affect sexual function.
