| Quick Answer
Stallegra 100 Mg contains Sildenafil Citrate, a PDE5 inhibitor used to treat erectile dysfunction in adult men. It typically starts working in 30 to 60 minutes and can remain effective for up to 4 to 6 hours, though some men notice effects for longer. It is a prescription-only medicine and should be taken no more than once in 24 hours, exactly as advised by a doctor. |
What is Stallegra 100 mg?
Stallegra 100 mg is a tablet containing Sildenafil Citrate, a phosphodiesterase type 5 (PDE5) inhibitor prescribed to treat erectile dysfunction (ED) in adult men.
ED is the repeated inability to get or keep an erection firm enough for sexual intercourse. It can result from physical causes such as reduced blood flow, nerve-related conditions, or hormonal changes, as well as psychological factors, and it becomes more common with age.
How Stallegra 100 mg Works
This medication works by improving blood flow to the penis during sexual arousal, allowing an erection to develop and be maintained.
- Sexual stimulation triggers the release of nitric oxide in penile tissue.
- Sildenafil Citrate blocks the PDE5 enzyme, which would normally break down a molecule called cGMP.
- With PDE5 blocked, cGMP levels rise and stay elevated.
- Higher cGMP relaxes the smooth muscle in the blood vessel walls of the penis.
- Blood flow into the penile tissue increases, producing an erection.
Sildenafil only supports this natural process; it does not cause an erection without sexual stimulation.
| Parameter | Typical Range |
| Onset of action | 30 to 60 minutes (can range 30 minutes to 4 hours) |
| Duration of effect | Around 4 to 6 hours for most men; some men respond for longer |
| Recommended timing | Take about 1 hour before planned sexual activity |
Key Benefits
- Clinically established mechanism for improving erectile function in men with ED
- Relatively fast onset, often within 30 to 60 minutes of taking the tablet
- Effective window of roughly 4 to 6 hours, giving flexibility around timing
- Widely studied PDE5 inhibitor with a well-documented safety and interaction profile
- Can help rebuild sexual confidence and ease strain in intimate relationships caused by ED
Dosage & Administration Guide
Stallegra 100 mg should only be taken on the advice of a doctor, who will confirm whether 100 mg is the right strength based on your health history and response to lower doses.
| Dose | Timing | Frequency | Food Instruction |
| 100 mg tablet | About 1 hour before sexual activity (window: 30 min–4 hrs) | No more than once in 24 hours | Avoid taking with a high-fat meal, as it can delay absorption |
Missed dose
Stallegra is taken as needed before sexual activity rather than on a fixed daily schedule, so a standard “missed dose” does not apply. Simply take it before your next planned activity, following the once-daily limit.
Overdose warning
Taking more than the prescribed amount does not improve results and raises the risk of side effects such as severe headache, vision changes, or a sharp drop in blood pressure. Seek urgent medical help if an overdose is suspected.
Alcohol, food, and grapefruit
- Alcohol: Excess alcohol can increase the risk of dizziness and low blood pressure; limit intake.
- Food: A heavy, high-fat meal can slow down how quickly the tablet starts working.
- Grapefruit: Grapefruit or grapefruit juice can raise sildenafil levels in the blood and should generally be avoided unless a doctor advises otherwise.
Who Should NOT Take It (Contraindications)
- Anyone currently taking nitrate medicines (for example, nitroglycerin or isosorbide) for chest pain or angina, since the combination can cause a dangerous drop in blood pressure.
- Anyone taking riociguat, a medicine used for pulmonary hypertension.
- Men with certain heart conditions, uncontrolled high or low blood pressure, or a recent heart attack or stroke, unless cleared by a doctor.
- Patients with significant liver or kidney impairment, who may need a lower dose or closer monitoring.
- Men under 18 years of age; Stallegra is intended for adult men only.
- Anyone with a known allergy to sildenafil or any tablet ingredient.
Drug Interactions
- Nitrates: Combining sildenafil with nitrate medicines or recreational “poppers” can cause a severe, potentially fatal drop in blood pressure. This combination must be avoided.
- Alpha-blockers: Taking sildenafil with alpha-blocker blood pressure medicines can increase the risk of dizziness or fainting from low blood pressure.
- Other PDE5 inhibitors: Sildenafil should not be combined with other ED medicines containing tadalafil or vardenafil.
- Blood pressure medicines: Sildenafil can add to the blood-pressure-lowering effect of other antihypertensive drugs.
- Alcohol and grapefruit: Both can affect how sildenafil is processed or tolerated, as noted above.
