What Is Penegra 100 mg?
Penegra 100 mg is an oral tablet containing sildenafil citrate 100 mg. It belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors and is used to treat erectile dysfunction (ED) in adult men. ED is the difficulty of getting or keeping an erection firm enough for sexual activity.
The medicine works as part of the body’s normal response to sexual stimulation. It does not increase sexual desire or produce an erection simply because the tablet has been taken.
The 100 mg strength refers to the amount of sildenafil in one tablet. Penegra is intended for oral use, and the appropriate medicine strength can differ from one person to another depending on factors such as health conditions, other medicines and response to treatment. A 100 mg tablet should therefore be used only as directed by a healthcare professional.
Penegra 100 mg Uses
Penegra 100 mg is used to treat erectile dysfunction in adult men.
Erectile difficulties can have many causes, including health conditions, medicines, stress, anxiety, or lifestyle factors. A doctor may recommend sildenafil after considering the person’s medical history and other medicines.
Benefits of Penegra 100 mg
When prescribed for erectile dysfunction, Penegra 100 mg may help:
- Improve penile blood flow during sexual stimulation.
- Make it easier to achieve an erection when sexually aroused.
- Help maintain an erection suitable for sexual activity.
- Provide an as-needed treatment option for men with erectile dysfunction.
These effects depend on individual response, and sexual stimulation is still required.
How Does Penegra 100 mg Work?
Sildenafil works by inhibiting the PDE5 enzyme. This helps maintain higher levels of a chemical called cyclic GMP in the penis when sexual stimulation occurs. The resulting relaxation of blood vessels allows more blood to flow into the erectile tissue, supporting an erection.
Penegra 100 mg does not cause an erection on its own. Sexual stimulation is needed for sildenafil to produce its effect.
How to Take Penegra 100 mg
Take Penegra 100 mg exactly as directed by your doctor or pharmacist.
- Swallow the tablet with water.
- It is generally taken when needed before sexual activity rather than as a routine daily medicine.
- Sildenafil is commonly taken about one hour before sexual activity.
- Do not take more than one dose in 24 hours.
- Sexual stimulation is required for the medicine to work.
- A large or high-fat meal may delay the onset of action.
- Do not combine Penegra with other medicines for erectile dysfunction unless your doctor specifically tells you to do so.
Penegra 100 mg Dosage
The usual starting dose of sildenafil for erectile dysfunction is 50 mg taken as needed, and the dose may be adjusted according to response and tolerability. A 100 mg dose is the maximum recommended single dose for erectile dysfunction in the cited product information. It should not be taken more than once a day.
Because Penegra 100 mg contains the maximum recommended sildenafil dose for ED, it should be taken only when that strength has been prescribed or recommended for you. People taking certain medicines or those with some liver or kidney problems may require a lower dose.
Do not increase the dose yourself if 100 mg does not produce the desired response.
Available Strengths
Penegra is available in different sildenafil strengths, with the appropriate option depending on the individual’s medical needs and response to treatment.
Missed Dose
Penegra 100 mg is normally taken only when needed, so there is usually no scheduled dose to make up. If you did not take it before planned sexual activity, do not take an extra tablet later to compensate.
Overdose
Taking more sildenafil than prescribed can increase the chance and severity of side effects. If you have taken more than the recommended amount, seek medical advice promptly rather than taking another dose.
Penegra 100 mg Side Effects
Like other ED pills containing sildenafil, Penegra 100 mg can cause side effects. They do not occur in everyone and may vary in severity.

Drug Interactions
Tell your doctor or pharmacist about all medicines, vitamins, supplements, herbal products, and recreational substances you use before taking Penegra 100 mg.

| Alpha-blockers | The combination may cause dizziness or a drop in blood pressure, particularly when treatment is first started. |
| Certain HIV medicines | Some medicines can increase sildenafil exposure and may require a dose adjustment or avoidance. |
| Certain antifungals and antibiotics | Some can affect how sildenafil is broken down and may increase its concentration. |
| Other erectile dysfunction medicines | Do not combine sildenafil with other PDE5 inhibitors or ED treatments unless specifically advised by your doctor. |

Tell your doctor about any heart or blood-vessel problems, and never combine it with nitrate medicines, nitric oxide donors, or riociguat.

Women & Children

If you experience troublesome or persistent side effects, speak with your doctor or pharmacist before taking another dose.
