Question 1

What causes erectile dysfunction?

Accepted Answer

ED can be caused by a variety of factors including cardiovascular disease, diabetes, hormonal imbalances, stress, anxiety, depression, certain medications, and lifestyle factors such as smoking, excessive alcohol use, and lack of exercise. Often, ED results from a combination of physical and psychological causes.

Question 2

What is the difference between generic Viagra and brand-name Viagra?

Accepted Answer

Generic Viagra (Sildenafil) contains the exact same active ingredient, dosage, and efficacy as brand-name Viagra — the only difference is the manufacturer and price. Generic Sildenafil became available after Pfizer's patent expired and is FDA-approved to the same rigorous standards. At RxFor.Me, we prescribe generic Sildenafil, which costs a fraction of brand-name Viagra.

Question 3

Sildenafil (Viagra) vs Tadalafil (Cialis): Which ED medication is right for me?

Accepted Answer

Sildenafil (generic Viagra) works within 30–60 minutes and lasts 4–6 hours, making it ideal for planned sexual activity. Tadalafil (generic Cialis) takes 1–2 hours to take effect but lasts up to 36 hours, offering significantly more spontaneity. Tadalafil is also available as a daily low-dose option (2.5–5mg). Both are equally effective — your physician will recommend the best fit based on your lifestyle.

Question 4

How fast does Viagra (Sildenafil) work compared to Cialis (Tadalafil)?

Accepted Answer

Sildenafil (Viagra) typically takes effect within 30–60 minutes when taken on an empty stomach. Tadalafil (Cialis) may take 1–2 hours to reach full effectiveness but lasts significantly longer — up to 36 hours vs 4–6 hours for Sildenafil. Both require sexual stimulation to work and do not cause automatic erections.

Question 5

What are the side effects of Sildenafil (Viagra) and Tadalafil (Cialis)?

Accepted Answer

Common side effects of both Sildenafil and Tadalafil include headache, facial flushing, nasal congestion, indigestion, and dizziness. Tadalafil may also cause back pain or muscle aches. These side effects are usually mild and temporary. Rare but serious side effects include sudden vision or hearing changes — seek immediate medical attention if these occur.

Question 6

Can I take Cialis (Tadalafil) with other medications?

Accepted Answer

Tadalafil (Cialis) and other PDE5 inhibitors should NOT be taken with nitrates (like nitroglycerin) or alpha-blockers, as this combination can cause a dangerous drop in blood pressure. During your RxFor.Me consultation, our physician will review all your current medications — including blood pressure drugs, HIV protease inhibitors, and antifungals — to ensure safe prescribing.

Question 7

Is erectile dysfunction a normal part of aging?

Accepted Answer

While ED becomes more common with age, it is not an inevitable part of aging. Many men maintain healthy sexual function well into their 70s and beyond. ED at any age often signals an underlying health condition — such as cardiovascular disease or diabetes — that can and should be treated. You should not accept ED as simply "getting older."

Question 8

How long does Viagra last vs Cialis?

Accepted Answer

Sildenafil (Viagra) lasts 4–6 hours per dose. Tadalafil (Cialis) lasts up to 36 hours, earning it the nickname "the weekend pill." For men who prefer continuous readiness, daily low-dose Tadalafil (2.5mg or 5mg) maintains steady levels in your system so you don't need to time your dose around sexual activity.

Question 9

Can I take Cialis (Tadalafil) daily instead of as-needed?

Accepted Answer

Yes — daily low-dose Tadalafil (2.5mg or 5mg) is FDA-approved for daily use. This approach maintains a consistent level of the medication in your bloodstream, allowing for spontaneous sexual activity without planning around a pill. Daily Cialis is also approved to treat symptoms of benign prostatic hyperplasia (BPH). Your physician will help determine if daily dosing is right for you.

Question 10

What should I do if Viagra or Cialis stops working?

Accepted Answer

If Sildenafil (Viagra) or Tadalafil (Cialis) becomes less effective over time, our physicians can adjust your dosage, switch you to a different PDE5 inhibitor, or explore combination approaches. Lifestyle factors — including diet, exercise, alcohol intake, and stress — can also impact medication effectiveness. Contact RxFor.Me for a follow-up consultation to optimize your treatment plan.
