Swallow tablets whole with a drink of water or juice (but not grapefruit juice).https://www.giantrawsource.com/raw-steroid-powder/raws-powder-viagra-sildenafil-citrate.html
For erectile dysfunction, it's best to take sildenafil on an empty stomach. It may take longer to work if you take it with food.
If you forget to take it
If you have pulmonary hypertension and you forget to take a dose of sildenafil, take it as soon as you remember unless it's nearly time for your next dose. In this case, just leave out the missed dose and take your next dose at the usual time.
Never take 2 doses at the same time. Never take an extra dose to make up for a forgotten one.
If you often forget doses, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to help you remember to take your medicine.
If you take too much
Taking too much sildenafil can cause unpleasant side effects.
Talk to your doctor if you take too much sildenafil and you're worried about any of these side effects:
headaches
dizziness
indigestion
blocked nose
changes to your vision
