Long-term effect of sildenafil citrate on erectile dysfunction after radical prostatectomy: 3-year follow-up This study assesses the long-term efficacy and safety of sildenafil citrate for treating erectile dysfunction following radical prostatectomy (RP). Ninety-one patients with post-RP erectile dysfunction were included in the study. They were prescribed oral sildenafil citrate and surveyed using a self-administered questionnaire during the first year of treatment to evaluate treatment satisfaction, compliance, and safety. After three years, a follow-up survey was conducted with 48 patients who had responded positively to the drug. Sildenafil citrate was initially prescribed at a dose of 50mg, with a possible increase to 100mg based on need. At the three-year mark, 71% of the respondents were still responding to sildenafil. Among these patients, 31% had increased their dosage to 100mg.

Treated patients with sildenafil citrate remain satisfied and compliant with the treatment. For those of you taking Sildenafil (Viagra) to help with ED, I am asking this dosing question. I just got my first script from the online pharmacy my doctor sent it to, and the bottle says "Take two pills daily and 3 more 1 hour before sexual activity." And then on the "appointed day" take 5? Go to the Prostate Cancer Support Group. It seems to be common to do this to try and resolve ED issues. I'm not a medical professional, but here's a document on UCSF that someone on this blog mentioned in another thread. It has a section on Penile Rehabilitation that includes some information related to your question: Best wishes. I would think your doctor would’ve checked up before prescribing it for you though, but you never know.

Dosing adjustment guidelines have been defined for pediatric patients with Child-Pugh Class C. The dosage is based on medical condition, response to treatment, age, and weight. Refer to a doctor or pharmacist for guidelines on dosage. When taken for erectile dysfunction, this drug is used as needed so it is unlikely to be forgotten.

What should happen if a dose is missed?

If it is nearly time for the next scheduled dose, then the missed dose should be skipped. Sildenafil Citrate Tablets can be given to adults and children, but caution is advised for specific groups of patients. Pregnant It is not known whether Sildenafil causes fetal harm.

5.7 Combination with other PDE5 Inhibitors or Other Erectile Dysfunction Therapies

Breastfeeding This drug should be used if the benefits outweigh the risks. Though harm is not expected based on the drug properties, inadequate human data is available to evaluate the risk of infant harm. There is no human data available that addresses this drug’s effects on milk production. Children It is advised to avoid high-dose therapy with Sildenafil in pediatric patients, as there is a greater risk of mortality. Geriatric When used to treat erectile dysfunction, Sildenafil is typically well tolerated by healthy elderly male patients.

Can I take Viagra after I’ve had my prostate removed?

Studies have not shown significant differences in response but have reported that healthy elderly patients show a reduced clearance of the drug that could increase the risk of adverse effects. As this population is more likely to have medical conditions, it is advised to use a lower starting dose. This medication should be stored at room temperature between 15-30°C. Keep the tablets out of the reach of children and pets. For patients taking CYP3A4 inhibitors, the starting dose should be not more than 25mg per day. Yes, and I have spoken to her. The sildenafil is for "lung blood pressure", whatever that means. It has not impacted my pulse rate or my BP. I think I'm just sensitive to it.

• Sildenafil is not an aphrodisiac and needs sexual stimulation.
• It does not increase libido directly.
• Effectiveness varies between individuals.

It can cause problems if you normally have low blood pressure.

4.1 Nitrates

For patients taking ritonavir-boosted HIV inhibitors, the maximum dosage is 25mg in 48 hours. For stable patients taking alpha-blockers, the starting dose should be 25mg. It is advised to monitor blood pressure and pulse when this drug is used with hypotensive medications. The combination of Sildenafil with nitrate and nicorandil can lead to a significant drop in blood pressure, which can potentially be fatal. As with all pharmaceuticals, some unwanted effects can occur from the use of Sildenafil Citrate Tablets.

VIAGRA is a phosphodiesterase-5 (PDE5) inhibitor indicated for the treatment of erectile dysfunction (ED) (1) For most patients, the recommended dose is 50 mg taken, as needed, approximately 1 hour before sexual activity. However, VIAGRA may be taken anywhere from 30 minutes to 4 hours before sexual activity (2.1) Based on effectiveness and toleration, may increase to a maximum of 100 mg or decrease to 25 mg (2.1) Maximum recommended dosing frequency is once per day (2.1) For most patients, the recommended dose is 50 mg taken, as needed, approximately 1 hour before sexual activity. However, VIAGRA may be taken anywhere from 30 minutes to 4 hours before sexual activity. VIAGRA may be taken with or without food. VIAGRA was shown to potentiate the hypotensive effects of nitrates and its administration in patients who use nitric oxide donors such as organic nitrates or organic nitrites in any form is therefore contraindicated [see Contraindications (4.1), Drug Interactions (7.1), and Clinical Pharmacology (12.2) ]. When VIAGRA is co-administered with an alpha-blocker, patients should be stable on alpha-blocker therapy prior to initiating VIAGRA treatment and VIAGRA should be initiated at 25 mg [see Warnings and Precautions (5.5), Drug Interactions (7.2), and Clinical Pharmacology (12.2) ]. The recommended dose for ritonavir-treated patients is 25 mg prior to sexual activity and the recommended maximum dose is 25 mg within a 48 hour period because concomitant administration increased the blood levels of sildenafil by 11-fold [see Warnings and Precautions (5.6), Drug Interactions (7.4), and Clinical Pharmacology (12.3) ].

• Typical sildenafil dose ranges from 25 to 100 mg.
• It should be taken 30-60 minutes before activity.
• Do not exceed one dose within 24 hours.

Clinical data have shown that co-administration with saquinavir or erythromycin increased plasma levels of sildenafil by about 3 fold [see Drug Interactions (7.4) and Clinical Pharmacology (12.3) ].

Medication Class	Interaction Type	Effect	Clinical Significance
Nitrates	Additive hypotensive effect	Severe hypotension	Contraindicated
Alpha-blockers	Enhanced hypotension	Blood pressure drop	Use with caution
CYP3A4 inhibitors	Increased sildenafil levels	Prolonged or intensified side effects	Dose adjustment may be needed
Protease inhibitors	Elevated sildenafil levels	Increased adverse effects	Monitoring required

Consider a starting dose of 25 mg in patients > 65 years, patients with hepatic impairment (e.g., cirrhosis), and patients with severe renal impairment (creatinine clearance <30 mL/minute) because administration of VIAGRA in these patients resulted in higher plasma levels of sildenafil [see Use in Specific Populations (8.5, 8.6, 8.7) and Clinical Pharmacology (12.3) ].
