Stendra (Avanafil) Buyer and Patient Handbook in Singapore
What is Stendra?
Stendra is a fast-acting oral tablet belonging to the phosphodiesterase-5 inhibitor class, used to treat Erectile Dysfunction in adult men. It improves blood flow to the penis to help achieve and maintain an erection when sexual stimulation occurs. The medication is approved by the Health Sciences Authority (HSA) in Singapore and is available in 50 mg, 100 mg and 200 mg strengths.
Who Should Use Stendra?
- Men aged 18 years and older with diagnosed erectile dysfunction
- Individuals who can engage in sexual activity within 15 minutes after dosing
- Those who have no contraindications such as severe heart disease or use of nitrates
How Does It Work?
Stendra blocks the enzyme phosphodiesterase-5, which normally degrades a compound called cyclic GMP that relaxes smooth muscle in the penile arteries. By preserving cyclic GMP, blood vessels dilate, allowing more blood to fill the erectile tissue during sexual arousal. The effect is comparable to turning on a water tap when you need it; the drug simply makes it easier for the body’s natural signal to work.
Why Choose Stendra?
Stendra offers a rapid onset-typically within 15 minutes-making it more convenient for spontaneous intimacy. Its flexible dosing options let users start low and increase only if needed, providing a balance of efficacy and safety. While brand-named Stendra is available, clinically equivalent generic avanafil tablets may offer cost savings without compromising quality.

Reviews
Started on the 50mg Stendra. It's fast, definitely faster than Sildenafil. Like, 15 minutes and it's kicking in. The downside? My face feels like I ran a marathon in sauna. Intense flushing, bright red. I heard taking it with a small meal helps slow the onset and maybe lessen the initial shock. Still figuring out the timing. Good solid performance though, no complaints there.
Been using Avanafil for over a year now, 100mg usually. The key is hydration, seriously. If I don't drink enough water, the mild headache turns into a full-blown migraine the next day. Pro-tip: Split the 200mg pill. You save money and a 100mg dose often works just as well without the intense nasal congestion. Performance is reliable, very little lag time after taking the pill. Overall stable.
First time trying Stendra 100mg. WOW, the speed is nuts. It bypassed the initial awkward waiting period I had with Tadalafil. Major drawback: I felt extremely congested, like a severe head cold, for about two hours. I tried taking it with an antihistamine the second time, and that seemed to manage the stuffiness quite well. Felt good, solid duration, but that initial stuffy nose sucks.
I only use the 50mg dose now. I tried 100mg and the back pain was unbearable-felt like my lower spine was locked up. With 50mg, I get the desired effect without the osteo pain. If I take it on an empty stomach, it hits faster, but the side effects (mild heartburn) are worse. So, I take it right after a small protein shake. That's my hack. It gives me about 4-5 hours of solid response.
Mixed feelings. It works perfectly for the physical aspect, definitely provides the rigidity needed. However, I get this weird foggy-headed feeling sometimes, almost like a light brain zap if I stand up too quickly. It only happens when I push the dose to 200mg. Sticking to 100mg and ensuring I eat rice or complex carbs beforehand seems to stabilize the head effects. Still better than the alternatives regarding pain.
The fastest one I've used yet. Seriously, maybe 12 minutes on an empty stomach. Long-term use (6 months) hasn't diminished the effect. My trick: absolutely no alcohol within 4 hours before and after. If I even have one beer, the immediate effect is diminished, and the headache is guaranteed. Keep it dry and the congestion is minimal. Very pleased with the consistency, but that headache is a hard line.
Tried 200mg once. Never again. The side effect profile was intense: racing heart, severe facial flushing, and I couldn't sleep that night. It worked, yes, but felt too aggressive. I've settled on cutting the 100mg pills into quarters (25mg). It's enough for maintenance, almost daily use, without impacting my sleep or giving me that tell-tale red face. Much more mellow and manageable at a micro-dose.
I have to take it. The speed is key for my situation, but I get the worst dry mouth. Like sandpaper tongue bad. I found chewing sugar-free gum (Xylitol) right after I take the pill helps stimulate saliva flow and makes the next few hours bearable. I run 100mg. It's reliable, less side effects than Viagra in terms of visual changes, but definitely brings the heat with the dry mouth.
