What is Sildenafil?

Sildenafil, known commercially as Viagra 100 mg, is a medication primarily used to address erectile dysfunction (ED). It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. By blocking PDE5, it enhances the effect of nitric oxide in the body, a natural chemical that relaxes muscles in the penis, allowing for increased blood flow and an erection in response to sexual stimulation. While it is most famous for its role in treating ED, sildenafil also finds use in managing pulmonary arterial hypertension (PAH) under the brand name Revatio. It works similarly in PAH by relaxing blood vessels in the lungs, improving blood flow, and reducing blood pressure in this area.

Sildenafil 100 mg is taken orally, typically about an hour before planned sexual activity. Its effects can last up to four hours. However, sexual arousal is necessary for its effects to be realized. This medication offers a significant impact on improving quality of life for those struggling with sexual dysfunction or PAH.

Sildenafil Use

Usage of sildenafil is guided by a healthcare provider to ensure optimal benefit while minimizing risks. For ED, patients are advised to take sildenafil approximately one hour before sexual intercourse, though it can be effective anywhere from 30 minutes to four hours prior. Dosage might vary based on efficacy and tolerance, but typically does not exceed 100 mg per day.

For PAH, sildenafil is taken more regularly, often three times a day. This regimented schedule helps in maintaining consistent levels of the drug in the bloodstream, crucial for managing the chronic nature of this condition. In both uses, adherence to medical advice is paramount.

Patients are encouraged to discuss their full medical history and current health status with their doctors. This communication helps in tailoring the use of sildenafil to individual health needs and mitigating potential side effects.

Who Can and Cannot Take Sildenafil

Not everyone can safely use sildenafil 100 mg. Generally, it is prescribed for adult men with ED and individuals with PAH. However, several health conditions contraindicate its use. These include severe heart problems, recent history of stroke or heart attack, and certain genetic eye disorders.

Men advised against sexual activity for health reasons should avoid sildenafil. Similarly, those taking nitrate drugs for chest pain or heart problems must not use it, as this combination can lead to a dangerous drop in blood pressure. Patients with liver or kidney issues, as well as those with blood cell disorders, need careful consideration before starting treatment.

Pregnant women or nursing mothers, particularly those using sildenafil for PAH, should consult extensively with their healthcare providers. While sildenafil for ED is not for women, the PAH indication may present unique considerations.

Sildenafil Interactions

Sildenafil 100 mg interacts with various substances, which may alter its effectiveness or increase the risk of adverse effects. Combining it with nitrates or nitric oxide donors can result in severe hypotension. Caution is advised with alpha-blockers, antihypertensives, and other PDE5 inhibitors.

Grapefruit and its juice can impact how sildenafil is metabolized in the body, potentially leading to increased side effects. Similarly, certain medications such as ritonavir and other protease inhibitors can elevate sildenafil levels in the bloodstream.

Patients should disclose all medications, supplements, and herbal products they use to their healthcare providers. This transparency ensures safe use of sildenafil and helps in managing any potential interactions.

How to Cope with Side Effects of Sildenafil

Common side effects of sildenafil 100 mg include headaches, flushing, and dizziness. While these are generally mild and transient, they can be uncomfortable. Staying hydrated, resting, and avoiding alcohol can mitigate some effects.

Less common but more serious side effects like sudden vision or hearing loss require immediate medical attention. For milder symptoms, over-the-counter pain relievers or a change in dosage, guided by a doctor, may help. Staying calm and informed aids in effective management.

Regular follow-up with a healthcare provider is crucial. It ensures that any side effects are monitored and managed appropriately. Patients are advised to report new or worsening symptoms promptly.

Purchasing sildenafil online offers convenience but requires caution. Consumers should ensure they buy from reputable pharmacies. Verification of the pharmacy’s legitimacy and consultation with a healthcare provider are essential steps.

Many online platforms sell sildenafil 100 mg, but counterfeit products pose a risk. These can be ineffective or harmful. It is vital to avoid unauthorized sellers who promise significant discounts or do not require prescriptions.
