This product is contraindicated for patients who have lost vision due to non atherosclerotic anterior ischemic optic neuropathy (NAION).
Who needs to use vardenafil hydrochloride tablets with caution?
For patients with anatomical deformities of the penis (such as angulation, corpus cavernosum fibrosis, Peyronie's disease), or inability to resolve penile spasms and erections (such as sickle cell disease, which often occurs in myeloma and leukemia), caution should be taken when treating erectile dysfunction.

The usage of this product is oral, with a recommended starting dose of 10mg. It should be taken approximately 25-60 minutes before sexual intercourse, with a maximum recommended frequency of daily use. Vardenafil can be taken with food or alone, and requires sexual stimulation as an instinctive response for treatment.

Treatment requires sexual stimulation as an instinctive response.
Dose range:
According to the efficacy and tolerability, the dosage can be increased to 20mg or reduced to 5mg. The maximum recommended dose is 20mg per day.
Liver damage
Patients with mild liver damage do not need to adjust their dosage. For patients with moderate liver damage, due to the reduced clearance rate of vardenafil, it is recommended to start at 5mg and gradually increase to 10mg based on tolerance and efficacy; The pharmacokinetic studies of denafil in patients with severe liver damage have not been conducted yet.
Renal damage
Patients with mild, moderate, or severe kidney damage do not require dose adjustment. The pharmacokinetics of vardenafil in dialysis patients has not been studied yet.
Notice after use:
During the treatment with this product, patients should consider their own response to vardenafil before driving and operating machinery.
How long does it usually take to take effect after using vardenafil hydrochloride tablets?
Vardenafil is rapidly absorbed after oral administration and reaches its maximum blood concentration within 15 minutes under prohibition. The peak time is 90% between 30-120 minutes (average of 60 minutes).
How long can the efficacy of vardenafil hydrochloride tablets generally be maintained?
The total clearance rate of vardenafil in the body is 56L/h, and its final half-life is 4-5 hours.
What should I do if I miss the use of vardenafil hydrochloride tablets?
After taking too little or forgetting to take it, do not overdo it and continue to take it according to the doctor's prescription
What should I do if I overdo using vardenafil hydrochloride tablets?
In a single dose subject study, the highest experimental dose reached 120mg per day (including 120mg). The highest experimental dose (80mg daily) was well tolerated without any serious adverse drug reactions. The same results were confirmed in another clinical trial using 40mg vardenafil (once daily) for 4 consecutive weeks. When vardenafil was taken at a dose of 40mg twice daily, several cases of severe back pain were observed, but no muscle or neurotoxic effects were confirmed.
When taking excessive medication, symptomatic treatment measures should be given as needed. Due to the high binding rate of vardenafil to plasma proteins and not primarily cleared by urine, renal dialysis does not increase its clearance rate in the body.
What are the adverse reactions of vardenafil hydrochloride tablets?
The common adverse reactions of vardenafil hydrochloride tablets include flushing, indigestion, nausea, dizziness, and rhinitis.
Under what circumstances is it necessary to immediately stop using vardenafil hydrochloride tablets?
