Sildenafil vs Tadalafil Reddit: Storing & Refilling in SG

I spent about three weeks reading Reddit threads before I bought anything — r/SingaporeRaw, r/erectiledysfunction, a few Telegram groups that shall remain unnamed. The question I kept typing was “sildenafil vs tadalafil reddit” and the answers were all over the place. Half the guys swore by the blue pill, the other half said tadalafil is the only sane choice. Almost nobody talked about the thing that actually matters after month two: storage and refills.

So here’s the version of that thread I wish existed. Same comparison, but with the boring parts included, because the boring parts are where the money goes.

Why the Reddit comparison misses half the story

Most threads compare onset time and side effects. Fair. Sildenafil kicks in around 30 to 60 minutes, tadalafil takes maybe 1 to 2 hours but lasts up to 36. Sildenafil gives more headaches and flushing in my experience. Tadalafil gave me mild back ache the first week, then nothing.

What nobody mentions: sildenafil comes in small packs of 4 usually, tadalafil 5mg comes in 28-day boxes meant to be taken daily. That single difference changes how you store the stuff, how often you reorder, and what happens when a box sits in a Tampines HDB cupboard for eight months through two monsoon seasons.

Storage: the humidity problem nobody on Reddit warns you about

Singapore sits at 80 to 90 percent relative humidity most days. HSA labelling for most PDE5 tablets says store below 30°C, dry place, away from light. Your bathroom cabinet fails that test. So does the kitchen shelf above the stove.

I keep mine in the original blister, inside a small airtight container, in a bedroom drawer away from the window. Sounds fussy. It isn’t, once you’ve had a strip of pills go soft and chalky because you left them in a Jurong flat with the window open.

Practical rule: keep the blister and the outer box with the expiry date. Loose pills in a pill organiser are a bad idea for ED meds because you lose the batch info. If you’re on daily tadalafil 5mg, decant a week at a time, not a month.

Expiry: what the dates actually mean

Both sildenafil and tadalafil are stable compounds. Manufacturers usually print 24 to 36 months from the date of manufacture, not from when you bought it. Check the box, not the invoice.

Here’s the thing Reddit gets wrong. Guys buy a 28-pack of tadalafil “to save on shipping” and then use it once a fortnight. That box is now a two-year supply and the expiry creeps up on you. Sildenafil’s small 4-pack format is actually kinder here, because you finish it.

My honest take: don’t stockpile more than about four months of supply. The savings from a bigger order rarely beat the waste from an expired box.

Cost over a year: the refill math

This is where sildenafil vs tadalafil reddit threads go quiet, because most posters are American and quoting insurance copays. Singapore is cash, so the annual number matters.

So daily tadalafil is roughly double the annual spend of as-needed sildenafil. Whether that’s worth it depends on how often you actually need it. If it’s twice a month, sildenafil wins on cost and on storage (smaller packs, less waste). If it’s most weekends plus spontaneous weekday situations, the daily 5mg route stops you doing mental arithmetic at 10pm.

For a fuller breakdown of what online pharmacies charge versus walk-in clinics, the 2025 tadalafil online cost and safety guide has actual figures rather than vague ranges.

Buying difficulty: refills are the real friction

First purchase is the hard part. Refills should be easy. In Singapore, repeat orders from a legitimate teleconsult provider usually need a fresh consult every 6 to 12 months, depending on the clinic. Some Reddit posters complain about this. I think it’s reasonable, and HSA expects a prescriber relationship for prescription-only medicines.

What you want from a refill channel: local customer service you can call, delivery within 2 to 3 working days, discreet packaging, and a clear batch number on the box. If a seller can’t tell you the expiry date before shipping, walk away.

My pick, and who shouldn’t take it

After all that reading and one wasted strip of damp pills, I landed on as-needed tadalafil 20mg, kept in a sealed container in a bedroom drawer, reordered roughly every 10 weeks. The longer window suits my schedule better than sildenafil’s tighter timing.

But I was wrong about one thing early on. I assumed daily 5mg would be cheaper per dose. It isn’t, not at my usage rate, and I ended up with a half-used box approaching expiry. If you’re a once-a-fortnight guy, buy small and buy often.

Don’t choose tadalafil if you get meaningful back or muscle ache from it, if you’re on nitrates (hard no, both drugs), or if you genuinely only need help a few times a year. And if you’re set on avoiding prescription meds entirely, there are natural alternatives to tadalafil worth reading about, though manage expectations.

FAQ

Can I store tadalafil in the fridge?

No need, and condensation is a risk when you take it out. A cool dry drawer below 30°C is fine.

Does expired tadalafil still work?

Probably partially, but potency drops and you can’t verify storage conditions. Not worth it for the price of a new box.

Is sildenafil or tadalafil cheaper to refill in Singapore?

Sildenafil, generally, because packs are smaller and you buy less at a time. Daily tadalafil 5mg is the most expensive refill pattern.

How long does delivery take for refills?

Local providers typically 2 to 3 working days. Anything quoting a week from overseas is a customs risk.

Can I split tadalafil tablets to stretch a box?

Only if they’re scored. Most 20mg tablets are, but check with the prescriber first.

What does HSA say about buying online?

Prescription-only medicines need a valid prescription from a Singapore-registered doctor. Buy from providers who ask for a consult.

Should I keep the box or just the blister?

Keep both. The box carries the batch number and expiry, which matters if you ever need to check a recall.
