VIAGRA 100MG TABLET 4'S, like all medications, may cause some side effects, although not everyone will experience them.

Allergies
Contraindicated in allergyDo not take Viagra if you are allergic to sildenafil or any of the other ingredients in the tablet.
VIAGRA 100MG TABLET 4'S is specifically designed for use in adult men with erectile dysfunction and should not be used by women. There are no approved formulations for women, and its safety and effectiveness in females have not been well-established.
VIAGRA 100MG TABLET 4'S typically starts to work within 30 minutes to 1 hour after ingestion. However, the onset of action can vary depending on individual factors, such as the presence of food in the stomach. It is best to take this medication on an empty stomach for faster and more consistent results.
VIAGRA 100MG TABLET 4'S is not intended for daily use in men with erectile dysfunction. It should be taken only when needed, typically about one hour before sexual activity. Daily use or exceeding the recommended dosage can increase the risk of side effects and complications.
No, VIAGRA 100MG TABLET 4'S is a prescription medication, and it is illegal and unsafe to obtain it without a valid prescription from a licensed healthcare professional. Self-medication can lead to health risks and potential complications.
You should inform your healthcare provider about your complete medical history and all medications/supplements you are taking to avoid potential drug interactions or contraindications. VIAGRA 100MG TABLET 4'S should not be used with nitrates or nitric oxide donors, as this can lead to a dangerous drop in blood pressure.
Always follow your prescribed dosage and avoid taking more than recommended. Be aware of potential side effects like sudden vision/hearing changes or prolonged erection and seek immediate medical attention if they occur. VIAGRA 100MG TABLET 4'S is a prescription medication and should only be used under the guidance of a qualified healthcare provider. It is not approved for women, especially during pregnancy or breastfeeding.
The active ingredient in VIAGRA 100MG TABLET 4'S is SILDENAFIL.
VIAGRA 100MG TABLET 4'S is used to treat conditions related to Sexual Wellness, primarily erectile dysfunction in men.
Viagra is the brand name for sildenafil, a prescription medicine used to treat erectile dysfunction (ED) in adult men. ED is the inability to achieve or maintain an erection sufficient for satisfactory sexual activity. Viagra works by relaxing blood vessels in the penis, allowing increased blood flow when a man is sexually stimulated. It does not increase sexual desire and will not cause an erection without sexual arousal. It is not intended for use in women or children.
Viagra contains sildenafil, which is a phosphodiesterase type 5 (PDE5) inhibitor. During sexual stimulation, the body releases nitric oxide in the penis, which increases levels of a substance called cGMP. This causes the smooth muscles in the blood vessels of the penis to relax, allowing more blood to enter and produce an erection. PDE5 breaks down cGMP. By blocking PDE5, Viagra helps maintain higher levels of cGMP, supporting a normal erection response to sexual stimulation. It does not work without sexual arousal.
Men with liver problems must speak to a doctor before using Viagra. Liver disease can affect how the body processes sildenafil, leading to higher levels of the medicine in the blood and an increased risk of side effects. In some cases, a lower dose may be recommended, or the medicine may not be suitable at all, depending on the severity of liver impairment and other health issues. Never adjust your own dose or start Viagra without medical advice if you have any history of liver disease, including hepatitis, cirrhosis, or abnormal liver tests.
Kidney disease can change how sildenafil is removed from the body, which may increase the risk of side effects. Men with mild to moderate kidney impairment may still be able to use Viagra, but a doctor may choose a lower dose or advise extra caution. In severe kidney disease or in patients on dialysis, careful medical assessment is essential before prescribing Viagra. Do not take Viagra without informing your healthcare provider about any kidney problems, past or present, so they can decide if it is appropriate and how it should be used.
Viagra is not approved or recommended for use in women, including those who are pregnant or breastfeeding. Its safety and effectiveness for female sexual problems have not been established, and it is not intended as a treatment for women. If a woman is accidentally exposed to sildenafil, she should contact a healthcare professional for advice, especially during pregnancy or while breastfeeding. Women should not use Viagra for sexual enhancement or any other purpose unless specifically prescribed in a controlled clinical setting by a specialist, which is uncommon.
Viagra can cause side effects such as dizziness, blurred vision, or changes in color vision in some men. These effects can impair the ability to drive or operate machinery safely. Until you know how Viagra affects you, avoid driving, cycling, or using tools or machines. If you feel dizzy, light‑headed, or notice visual disturbances after taking Viagra, do not drive or perform tasks that require full alertness and clear vision. If these symptoms persist or are severe, seek medical advice before using Viagra again.
Alcohol can interfere with the ability to get an erection and may reduce the effectiveness of Viagra. Drinking a large amount of alcohol can also increase the risk of side effects such as dizziness, low blood pressure, and fainting. Moderate or heavy drinking around the time you take Viagra is therefore not recommended. If you choose to drink, keep alcohol intake low and be aware that both alcohol and Viagra can affect blood pressure and reaction time. Always follow your doctor’s advice regarding alcohol use with this medicine.
Before taking Viagra, tell your doctor and pharmacist about any allergies you have, especially to sildenafil or any of the other ingredients in the tablet. Signs of an allergic reaction can include rash, itching, swelling of the face, lips, tongue, or throat, severe dizziness, or difficulty breathing. If you experience any of these symptoms after taking Viagra, seek emergency medical help immediately and do not take another dose. Also inform your doctor about any past serious reactions to other medicines, as this may influence whether Viagra is suitable for you.
Viagra must not be taken by men who use nitrates (such as glyceryl trinitrate, isosorbide mononitrate, or isosorbide dinitrate) for chest pain, or certain medicines called guanylate cyclase stimulators, because the combination can cause a dangerous drop in blood pressure. It is also generally not recommended for men with severe heart or liver problems, very low blood pressure, recent stroke or heart attack, or certain rare eye diseases such as inherited retinal disorders. Only a doctor can decide if the benefits outweigh the risks in complex medical situations.
Viagra does not cure the underlying cause of erectile dysfunction and does not increase fertility. It helps manage the symptom of difficulty achieving or maintaining an erection by improving blood flow to the penis during sexual stimulation. Conditions such as diabetes, high blood pressure, hormonal imbalances, psychological stress, or relationship issues may still need separate treatment. Viagra does not affect sperm quality or protect against pregnancy or sexually transmitted infections. Men concerned about fertility or persistent ED should discuss comprehensive evaluation and treatment options with a healthcare professional.
