Viagra, with the active component sildenafil, is predominantly utilized for the treatment of erectile dysfunction (ED) in men. This condition is diagnosed when a man experiences a consistent difficulty in achieving or maintaining an erection adequate for engaging in sexual activity. Sildenafil enhances blood flow to the penis in response to sexual arousal, thereby assisting in the capability to attain an erection. However, it is crucial to recognize that Viagra does not serve as a complete cure for erectile dysfunction and does not amplify sexual desire. Moreover, it does not provide any protection against pregnancy or sexually transmitted infections.
Sildenafil, marketed under the brand name Revatio, is also prescribed for addressing pulmonary arterial hypertension (PAH), a serious ailment that affects the blood vessels in the lungs, potentially leading to symptoms such as breathlessness and fatigue. The medication acts by relaxing the blood vessels in the lungs, which subsequently facilitates enhanced physical performance for individuals suffering from PAH.
Viagra is accessible as oral tablets and is intended to be taken as per need. The standard dosage for erectile dysfunction is generally consumed approximately 1 hour preceding sexual activity; however, it can be ingested anywhere between 30 minutes to 4 hours before. It is critical to avoid taking Viagra more than once within a single day. Should you be utilizing sildenafil to mitigate PAH, it is permissible to take it up to three times daily, irrespective of meal times.
Precautions Before Taking Viagra
- It is advisable to inform your physician about any known allergies to sildenafil or other similar medications.
- Discuss any current medications you are taking with your healthcare provider, particularly if concurrently using nitrates, which are often prescribed for angina, as this conjunction could result in a perilous drop in blood pressure.
- Make sure to communicate any pre-existing heart conditions, liver or kidney disorders, history of stroke, or vision problems to your doctor, as these factors can influence your eligibility for sildenafil.
- If you encounter any sudden loss of vision or hearing, immediate medical assistance is required.
- Pregnant or breastfeeding women should disclose this to their healthcare provider before considering the use of sildenafil, as it is not recommended for females.

Storage and Disposal
Store Viagra in a cool, dry environment at room temperature, away from excessive heat and moisture, and ensure it is not kept in the bathroom. Keep all medications out of the reach of children and pets. When disposing of any unused medication, utilize a drug take-back program or consult your pharmacist for guidance on safe disposal methods.
If You Forget to Take a Dose
For erectile dysfunction, the usage of Viagra is on an as-needed basis, thus missing a dosage is not common. If the medication is being used for PAH and you miss a dose, take it as soon as you recall it. However, if the time is close to your next scheduled dose, skip the missed dose and continue with your regular regimen. Never attempt to double doses.
In Case of Overdose
In case of an overdose, reach out to poison control or emergency services without delay if symptoms such as severe dizziness, fainting, or an erection lasting longer than four hours occur.
