Sildenafil 100 mg: Uses, Dosage, Side Effects & Safety
If you are researching Sildenafil 100 mg, you may have questions about what it is, how it works, when it should be taken and what precautions are important. Sildenafil is a medicine commonly used to treat erectile dysfunction (ED), and 100 mg is one of the available strengths.
This guide explains Sildenafil 100 mg tablets in simple language, including their uses, dosage, possible side effects and important safety information.
What Is Sildenafil 100 mg?
Sildenafil 100 mg contains 100 mg of sildenafil citrate. It belongs to a group of medicines called PDE5 inhibitors and is used to improve blood flow to the penis during sexual stimulation.
Sildenafil does not automatically cause an erection and does not increase sexual desire. Sexual stimulation is still required for it to work.

What Is Sildenafil 100 mg Used For?
The most common use of Sildenafil 100 mg is the treatment of erectile dysfunction, a condition in which a man has difficulty getting or keeping an erection suitable for sexual activity.
Erectile dysfunction can have different causes, including health conditions, medicines, stress and lifestyle factors. If erection problems happen regularly, it is worth discussing them with a healthcare professional.
How Does Sildenafil Work?
Sildenafil works by helping increase blood flow to the penis during sexual stimulation. It does this by inhibiting an enzyme called PDE5, which helps support the blood flow needed for an erection.
Because sexual stimulation is necessary, sildenafil should not be thought of as a medicine that creates an erection on its own.
Sildenafil 100 mg Dosage
The appropriate sildenafil dosage depends on the individual and should be determined according to medical advice. For erectile dysfunction, 50 mg is commonly used as an initial dose, while the dose may be adjusted to 25 mg or 100 mg depending on effectiveness and tolerability.
Sildenafil 100 mg is generally taken when needed before sexual activity. It should not be taken more than once in a 24-hour period unless specifically instructed otherwise by a healthcare professional.
Sildenafil is commonly taken about one hour before sexual activity, although the timing can vary between individuals.
How to Take Sildenafil 100 mg
- Take Sildenafil 100 mg tablets exactly as prescribed.
- Swallow the tablet with water.
- Sildenafil can generally be taken with or without food.
- A high-fat meal may delay how quickly sildenafil starts to work.
- Do not take more than the prescribed dose.
- Do not take sildenafil more than once in a 24-hour period unless your healthcare professional tells you otherwise.
Following the instructions provided with your medicine is more important than increasing the dose or taking additional tablets.
Sildenafil 100 mg Side Effects
Like other medicines, Sildenafil 100 mg can cause side effects. Commonly reported effects may include:
- Headache
- Flushing
- Indigestion or heartburn
- Blocked or stuffy nose
- Dizziness
- Nausea
- Temporary changes in vision
Side effects can vary from person to person. Speak with a healthcare professional if side effects are severe, persistent or concerning.
Important Sildenafil Safety Information
One of the most important safety points is that sildenafil should not be taken with nitrate medicines, which are commonly used for chest pain. Combining sildenafil with nitrates can cause a dangerous drop in blood pressure.
Before taking sildenafil, tell your doctor or pharmacist about all prescription medicines, over-the-counter medicines, vitamins and supplements you use.
People with certain cardiovascular conditions, blood pressure problems or other medical conditions may require additional assessment before using an ED medicine.
Sildenafil and Alcohol
Drinking a large amount of alcohol can make it more difficult to achieve an erection and may increase some unwanted effects such as dizziness.
If you are taking sildenafil and alcohol together, avoid excessive alcohol. If you are unsure whether alcohol is appropriate with your medicines or medical conditions, ask a healthcare professional.
When Should You Seek Medical Help?
Most people do not experience serious problems, but certain symptoms require prompt medical attention.
Seek emergency medical help if an erection lasts longer than four hours. You should also seek immediate medical attention for sudden loss of vision, sudden hearing loss, severe allergic symptoms, chest pain or other serious or unexpected reactions.
