Sildenafil for ED: timing, effects and options in Bangkok

The short answer

Sildenafil is the active ingredient in Sidegra and Viagra. It helps erections in response to sexual stimulation and is generally used when needed. Kauri offers Sidegra 50 mg, Sidegra 100 mg and Viagra 100 mg.

How fast does sildenafil work?

Many people plan sildenafil around 1 hour before sex. Its response window usually lasts several hours, commonly around 4 hours, with variation between individuals. A large or fatty meal can delay the onset, so the same dose may seem slower after eating. Stimulation is needed; waiting for an automatic erection can make an otherwise suitable treatment seem ineffective.

What if sildenafil is not helping?

A review can check whether the medicine was taken as directed, whether enough time and stimulation were allowed, and whether meals or alcohol affected the experience. Persistent ED can also reflect circulation, diabetes, medications or emotional factors. Kauri can review relevant testing, another oral treatment or specialist referral. Increasing the dose yourself can add side effects without solving the cause.

Side effects: what should I know?

ED tablets are well tolerated by many patients. Headache, flushing, indigestion, nasal congestion and dizziness can occur. Sildenafil may cause temporary visual changes; tadalafil may cause back or muscle aches. Tell Kauri about troublesome effects so your treatment can be reviewed.
