PHYSICIAN-GUIDED ED CARE • FLORIDA
Talk directly with Timothy Mackey, D.O. about sildenafil (generic Viagra) and the health factors that may be contributing to erectile dysfunction. Visit our Jupiter office or meet by telemedicine anywhere in Florida when clinically appropriate.
A medical evaluation is required. A prescription is not guaranteed.

THE QUICK ANSWER
Yes—when a Florida medical evaluation shows sildenafil is appropriate. Sildenafil is a prescription PDE5 inhibitor used for erectile dysfunction. It can improve penile blood flow during sexual stimulation, but it does not automatically create an erection and it does not address every cause of ED.
Discuss symptoms, medical history, blood pressure, cardiovascular risk and every medication or supplement you take.
If treatment is appropriate, Dr. Mackey explains formulation, dose, timing, benefits, risks and alternatives.
Response and side effects matter. Follow-up helps determine whether the plan should continue, change or be reconsidered.
KNOW WHAT YOU ARE GETTING
Sildenafil is the active ingredient in Viagra. FDA-approved sildenafil tablets for ED are available in several strengths. A clinician selects the dose based on your health, medications, response and side effects.
NovaGenix may discuss a customized compounded formulation when there is a clinical reason. Compounded medications are prepared for an individual patient and are not FDA-approved finished drug products.

Erectile dysfunction may be associated with vascular disease, diabetes, medication effects, stress, sleep issues, low testosterone or other conditions. The goal is to identify safety concerns and decide whether sildenafil, another treatment or further evaluation makes sense.
If low desire, fatigue or other symptoms point toward a hormonal issue, targeted testing may be useful. Testosterone therapy should never replace a proper ED evaluation.

Sildenafil can interact with medications and can be inappropriate for some cardiovascular conditions. Tell the physician about every medication you take and any recent change in your health.
Sildenafil is contraindicated with nitrate medicines such as nitroglycerin because blood pressure can fall dangerously.
Some heart conditions, alpha-blockers, antihypertensives and other drugs require special caution or may make treatment inappropriate.
Seek urgent care for an erection lasting more than four hours, sudden vision or hearing loss, chest pain or other severe symptoms.
Common adverse effects can include headache, flushing, indigestion, nasal congestion and visual changes. This page is educational and not a substitute for medical advice.

COMMON QUESTIONS
Eligible Florida adults may complete a telemedicine evaluation. A prescription is issued only when the evaluation supports it and telemedicine is clinically appropriate.
Sildenafil is the active ingredient in Viagra. FDA-approved generic tablets contain the same active ingredient, although inactive ingredients and appearance can vary.
The FDA labeling describes use approximately one hour before sexual activity, with a window of about 30 minutes to four hours. Individual response varies; follow your prescriber's instructions.
The FDA labeling states a maximum recommended frequency of once per day. That does not mean daily use is appropriate for everyone.
No. Sildenafil is contraindicated with nitrates, including nitroglycerin. Tell your clinician about all heart and blood-pressure medicines.
Do not increase the dose on your own. Timing, food, stimulation, medications and the cause of ED can affect response. Follow-up can identify the safest next step.
Sildenafil supports erectile function; it is not a treatment for low desire. If libido is also low, a separate evaluation may be appropriate.
No. The clinic is in Jupiter, and NovaGenix can serve eligible patients throughout Florida by telemedicine when clinically appropriate.
