Taking Viagra (sildenafil) should always be done under the strict guidance of a healthcare professional. It is a prescription medication, and improper use can lead to serious health risks.
Dosage and strength for erectile dysfunction
The usual dose is 50mg, when you need it. Do not take it more than once a day. The dose can be increased to 100mg or decreased to 25mg depending on its effect. Take sildenafil up to 4 hours before you want to have sex.

Sildenafil usually should not be taken more than once every 24 hours. If you have certain health conditions or are taking certain medications, your doctor may tell you to take sildenafil less often. You can take sildenafil with or without food.

Sometimes, Viagra (Sildenafil) stops working as well as it did previously – either the erections are not as hard as they used to be or it is more difficult to get and keep erections. It is rare for people to develop tolerance to Viagra; for the most part, the drug works for the long haul.
Yes, you can split your Viagra tablets. Halving a pill doesn't affect its efficacy as the active drug sildenafil is distributed evenly throughout. If your prescribed dose is 50 mg or 100 mg, and you want to try reducing it, consult our expert medical team first. You should use a pill cutter to safely halve your tablet.
Keep in mind that splitting your pill in half and taking only one-half will change the dose of your medicine. For example, splitting a whole 50 mg tablet in half will typically give you two 25 mg halves. Only take half of your medicine if your healthcare provider has directed you to do this.
You may take this medicine with or without food. Swallow the tablet whole. Do not split, break, chew, or crush it.
