PATIENT DRUG INFORMATION
Sildenafil Citrate

Written information about this prescription has been provided for you. Please read this information before you take this medication. If you have questions concerning this prescription, a pharmacist is available during normal business hours to answer these questions.

Taking Your Prescription

Sildenafil tablets are taken by mouth approximately 1 hour prior to sexual activity, on an empty stomach. Do not exceed one dose every 24 hours. Check your prescription label for the correct dose prescribed by your medical provider. 

Sildenafil is used in men to treat erectile dysfunction and improve erections during sexual activity for up to 4 hours.

Sildenafil may also be used off-label to treat premature ejaculation, which means it hasn’t been FDA-approved to treat premature ejaculation.

Precautions

Do not take sildenafil if you have an allergy to sildenafil or any of its components.

Because of a potential dangerous drop in blood pressure, sildenafil must not be taken with nitrates. Examples of nitrates include nitroglycerin, isosorbide dinitrate, isosorbide

mononitrate, creatine nitrate, or arginine nitrate. Take extra precautions when consuming pre-workout supplements that may contain beet root extract and other organic nitrates. Before taking a supplement, check with your pharmacist to ensure the product does not contain nitrates. Do not take with other erectile dysfunction medications and supplements. Do not take with recreational drugs such as poppers or rush. If starting any new medications, including antibiotics, please contact the pharmacy to check for potential drug interactions. Avoid grapefruit juice when taking sildenafil.

If you have a history of heart, kidney, liver, ear or eye disease, be sure to tell your medical provider before taking sildenafil.

This medication should not be taken by women who are pregnant or breastfeeding.

Side Effects

The most common side effects when taking sildenafil are headaches, flushing and mild vision disturbances such as color-tinged or blurred vision with increased light sensitivity.

These side effects will commonly subside without further intervention. If these side effects persist for longer than expected, seek medical attention.

If you’re experiencing a painful or threatening reaction to your medication such as an erection lasting longer than 4 hours, please seek medical help now. Depending on the severity of your symptoms, you can either reach out to your prescriber, call 911 or visit a local urgent care.

Once you have determined your safety, please contact us. One of our pharmacists will assess what happened and provide guidance if needed. This may include pharmacist counseling to explain preventative techniques or recommend alternatives for your treatment.

This list may not describe all potential side effects. You may also report adverse events to the FDA by visiting: https://www.accessdata.fda.gov/scripts/medwatch/index.cfm or by calling 1-800-FDA-1088.

Monitoring Drug Therapy

If taking sildenafil at the prescribed dose does not improve your symptoms of erectile dysfunction, stop taking it and contact your medical provider.

Storage

Store sildenafil at room temperature (between 68 and 77 degrees F) in the packaging provided by the pharmacy. Keep out of reach of children.

Under certain circumstances a prescription drug’s effectiveness may be affected by exposure to extremes of heat, cold, or humidity.
