You should consult your health care professional before taking any drug, changing your diet, or commencing or discontinuing any course of treatment. The proper dosage for sildenafil (Viagra) will vary between 25mg and 100mg once daily, with the most prescribed dosage being 50mg. Patients generally start with a lower dosage of 25mg to 50mg and depending on how the starting dosage works including how well it interacts with the body, may move to a higher dosage for a better experience. (1) For treating erectile dysfunction (or ED), sildenafil is normally only taken on an as needed basis, 30-60 minutes before sexual activity but can be dosed between 30 minutes and 4 hours before sexual activity.
- 20mg sildenafil is a standard starting dose for many men.
- Its safety profile is well-established when used responsibly.
- The drug should be taken at least 30 minutes before sexual activity.
- Use caution if you experience dizziness or sudden vision loss.
- Always follow medical advice when using sildenafil for ED.
Sildenafil treats erectile dysfunction by selectively inhibiting an enzyme known as phosphodiesterase type 5, which allows corpus cavernosum smooth muscle to relax, making erections during sexual stimulation more satisfactory. (2) An erection is achieved in a response cycle that begins with sildenafil producing arteriolar dilatation and increased blood flow to the erectile tissue of the penis. (3) In a study on different dosages for treating erectile dysfunction with sildenafil, it was found that both 50 mg and 100 mg doses of sildenafil improved erectile function, sexual satisfaction, and enjoyment in patients, however the 100 mg dose had slightly better results. Higher doses led to improved sexual frequency and enjoyment, especially for patients with more severe cases of ED or if the patient had any additional health conditions.
If you forget to take it
Rarely, a sudden decrease or loss of hearing, sometimes with ringing in the ears and dizziness, may occur. Stop taking sildenafil and get medical help right away if these effects occur. Rarely, males may have a painful or prolonged erection lasting 4 or more hours. If this occurs, stop using this drug and get medical help right away, or permanent problems could occur.

However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: itching/swelling (especially of the face/tongue/throat) This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist. You may report side effects to FDA at 1-800-FDA-1088 or at In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345. Before taking sildenafil, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. The overall findings suggest that adjusting the sildenafil dosage can optimize treatment for an improved outcome and many patients who start at 50mg, request a higher dosage later on. The common tablet dosages for sildenafil when treating erectile dysfunction are 25mg, 50mg, and 100mg with 50mg being the dosage most often initially prescribed and with dosages designed for once daily dosing. (4) Professor Irwin Goldstein noted in a presentation on sildenafil in 2003 that taking a quarter pill of sildenafil every night was effective in preventing erectile dysfunction. “If you would like to be sexually active in five years' time, take a quarter of a pill a night, we have data to show that will facilitate and prolong nocturnal erections.” Speak with your doctor if you have been taking sildenafil as needed and want to try switching to a daily micro dose. Sildenafil is considered generally a low-risk drug (although there are some important adverse effects and some contra-indications to taking sildenafil) and has been approved by the FDA (Food and Drug Administration) since 1998 for treating erectile dysfunction. Sildenafil prescriptions for erectile dysfunction typically start at 50mg and should be taken no more than once per day.
