What It Is and How It Works
Viagra belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. It works by inhibiting the PDE5 enzyme in the body, which is found in the walls of blood vessels. Inhibition of this enzyme leads to an increase in cyclic guanosine monophosphate (cGMP) levels, causing the smooth muscles in the blood vessels of the penis to relax. This relaxation allows increased blood flow, facilitating an erection with sexual stimulation. It is important to note that Viagra only works with sexual arousal and does not increase sexual desire.
Indications / Uses
Viagra is primarily indicated for the treatment of erectile dysfunction. While its effectiveness for this purpose is well-documented, it should only be used under the guidance of a healthcare professional. Occasionally, it is used off-label for other conditions such as pulmonary arterial hypertension, but such uses require medical supervision and are beyond its traditional scope.
Dosage Forms and Typical Dosing Considerations
Viagra is available in tablet form, and its standard doses are 25mg, 50mg, and 100mg. The 200mg dose is generally not recommended as a starting dose and should only be considered under strict medical guidance if lower doses are ineffective and well-tolerated. Factors such as age, liver function, and other health conditions may influence the dosing. Patients should always follow the prescribed dosage and seek advice if they need adjustments.
How to Take It Correctly Step-by-Step
Viagra should be taken as follows:
- Take one tablet orally, ideally on an empty stomach.
- It should be taken approximately 30 minutes to 1 hour before planned sexual activity, but it can work up to 4 hours after taking.
- Avoid consuming alcoholic beverages or high-fat meals before taking Viagra, as these can delay its effect.
- Do not take more than one tablet within a 24-hour period.
- If a dose is missed (in terms of anticipated activity), it should not be taken close to another dose.

Contraindications & Precautions
Individuals with heart conditions, those taking nitrates, or people with severe liver impairment should avoid Viagra. It is not prescribed for women or children. Those with allergies to sildenafil or any of its ingredients should not use this medication. Special caution is required for elderly patients or those with kidney or liver disease, and only a healthcare professional can assess individual risks.
Drug, Food, and Supplement Interactions
The use of Viagra with nitrates or other blood pressure-lowering medications could result in a dangerous drop in blood pressure. Also, some antifungals and antibiotics may alter its efficacy. Patients should provide a complete list of their current prescriptions, over-the-counter drugs, and supplements to their healthcare provider to avoid interactions. Alcohol can exacerbate certain side effects and should be limited.
