Vega 100 Guide: Understanding This Generic Sildenafil Tablet
Reviewed by the Kam4eu Pharmacy Team on 22 January 2026 · Next review June 2027
What is Vega 100?
Vega 100 is a generic brand of sildenafil citrate, a PDE5 inhibitor used to help men achieve and maintain erections. As with other sildenafil products, the active ingredient is the same well-established compound, so Vega behaves like other sildenafil tablets; the brand name reflects its manufacturer.

How Vega 100 works
An erection depends on blood flowing into the penis. During arousal, blood vessels relax and fill, while the PDE5 enzyme later reverses the process. Sildenafil temporarily blocks PDE5, helping the erection last while arousal continues. It supports a natural response rather than creating one, so stimulation is still required.
The Sildenafil guide breaks this down further.
Who might use it
Because erectile dysfunction can stem from many causes, a discussion with a doctor or pharmacist is a sensible first step. They can confirm whether a sildenafil product like Vega is appropriate and safe for you.
They may consider:
- Heart and blood vessel health
- Blood pressure and diabetes
- Psychological factors
- Other medicines you take
- Lifestyle elements
Sensible use
Sildenafil products are generally taken before planned sexual activity, and a heavy meal can delay their effect. Follow the patient information leaflet and your prescriber's guidance on timing and intake, and never take more than advised.
Important safety information
These apply to Vega 100 and all sildenafil brands:
- Never combine it with nitrates or poppers, as this can dangerously lower blood pressure.
- It works only alongside sexual arousal.
- An erection lasting more than four hours is a medical emergency.
- Tell your prescriber about heart disease, recent stroke, low blood pressure and liver or kidney problems.
Mild side effects can include headache, flushing, a blocked nose, indigestion and brief visual changes. Seek advice for severe or persistent effects.
How Vega 100 compares
Being a sildenafil product, Vega 100 usually lasts a few hours. Some men prefer tadalafil for its longer window of effect, while others find sildenafil suits them well. Our Tadalafil vs Sildenafil article covers the differences in duration and timing.

Storage and buying safely
Keep Vega 100 in its original packaging, away from heat and moisture, and out of children's reach. Check the expiry date and discard anything damaged. A reputable pharmacy is the safest source for authentic, well-stored medicine.
Erectile dysfunction is common and manageable, and professional advice is the best way to find a treatment that fits your needs.
