FAQ
Which Zydena pack sizes can I order?
Zydena comes as 100mg tablets in packs of 4, 8, 16, 24, 32, 64 or 92. This is generic udenafil, not the original Zydena. Larger packs cost less per tablet.
Is Zydena delivered discreetly to Hong Kong?
Every Zydena order arrives in plain, unbranded packaging with nothing on the outside about the contents. Delivery is by tracked courier in 5 to 9 business days with online tracking, or standard airmail in 14 to 21 business days. Payment can be by card or Bitcoin and Ethereum.
Can I take Zydena two days in a row?
Yes — udenafil is taken when you need it, so a gap of a day or more between tablets is normal. Just keep to one 100mg tablet in any 24 hours. There is no build-up effect, so nothing carries over from one evening to the next.
How long does the effect of Zydena last?
It varies from man to man, and there is no fixed number of hours to quote: the effect depends on arousal continuing and fades as the body clears udenafil. The limit that does not change is one 100mg tablet in any 24 hours.
Is Zydena the same as Viagra?
Not exactly. Viagra's active ingredient is sildenafil, while Zydena contains udenafil. Both are PDE5 inhibitors taken shortly before sex, but they are separate compounds with their own doses and side effect profiles.
Can I drink alcohol with Zydena?
A drink or two with a meal is unlikely to matter, but a heavy night raises the chance of headache, flushing, dizziness and low blood pressure, which can spoil the evening. If a big drinking session is planned, the tablet is better saved for another night.
How long do the side effects last?
The common ones — headache, flushing, a blocked nose, indigestion and dizziness — are usually mild and ease within a few hours as the body clears the tablet. How noticeable they are varies from man to man and from one occasion to another.
About Zydena
What Zydena tablets are
Zydena is udenafil 100mg in tablet form, a phosphodiesterase-5 (PDE5) inhibitor used for erectile dysfunction, meaning difficulty getting an erection or holding it long enough for intercourse. Sildenafil and tadalafil belong to the same class. Udenafil relaxes the arteries of the penis so blood can flow in and stay while arousal continues. The tablet needs sexual stimulation; on its own it does nothing. What is sold here is generic udenafil, 100mg tablets, in packs from 4 up to 92. The ingredient itself is covered on the udenafil page.
How is a Zydena tablet taken?
Swallow one tablet with water about 30 minutes ahead of sex. The limit is one tablet in any 24 hours. Zydena is a take-when-needed medicine, not a daily one, so there is no schedule to keep, and a further tablet later that night adds no extra effect. Drinking heavily makes flushing, headache, dizziness and low blood pressure likelier.
Side effects of Zydena
Most men who get side effects have a headache, a warm flushed face, a stuffy or runny nose, an upset stomach or some dizziness. These are usually mild and fade within hours. Sudden changes in sight or hearing are rare but real. A painful erection that has not gone down after four hours is an emergency, and so is swelling of the lips, face or throat after a dose, which points to a serious allergy.
Medicines that clash with udenafil
Nitrates matter most. GTN for angina, isosorbide tablets and the amyl nitrite in poppers all push blood pressure down hard when combined with udenafil. Alpha-blockers taken for prostate trouble or high blood pressure add to that drop. Strong antifungals such as ketoconazole and itraconazole make the body break udenafil down more slowly, leaving a higher level in the blood.
Looking after the tablets
Store the strips in their box, out of sunlight and away from damp. Look at the expiry date printed on the strip before you begin a pack. Sizes run from 4 tablets up to 92, so the pack can follow how often you expect to use Zydena.
