Sildenafil (oral route)
It is crucial for you to inform all your healthcare providers that you are currently taking sildenafil. This is especially vital in emergency situations when you might require medical attention for a heart-related issue. Knowing when you last took sildenafil can significantly influence the treatment decisions your doctor makes.
In addition, you should not use this medication if you are concurrently taking any nitrate medications, which are commonly prescribed for the treatment of angina or high blood pressure. Examples of nitrate medicines include nitroglycerin and isosorbide, which are available in various formulations such as Imdur®, Nitro-Bid®, Nitro-Dur®, Nitrol® ointment, Nitrolingual® spray, Nitrostat®, and Transderm Nitro®. Furthermore, avoid the use of illegal substances known as "poppers," which contain amyl nitrate or butyl nitrate. Do not combine sildenafil with riociguat (Adempas®), as this could lead to serious complications.
For those prescribed sildenafil to treat pulmonary arterial hypertension, it's essential to have regular follow-ups with your healthcare provider. These appointments allow for monitoring of your response to the medication and adjustments to your treatment plan as necessary.
If you are using sildenafil for pulmonary arterial hypertension, refrain from taking Viagra® or any other PDE5 inhibitors, such as tadalafil (Cialis®) or vardenafil (Levitra®), as this could increase the risk of adverse effects. Remember that Viagra® contains sildenafil, and taking it alongside sildenafil can elevate the potential for side effects.
Sildenafil is not to be used in conjunction with any alternative medicines or devices that induce erections, as this can lead to unforeseen complications.
It's of utmost importance to discuss any existing heart conditions with your doctor, as sildenafil can pose serious risks for individuals with a history of heart problems.
If you experience a prolonged or painful erection lasting 4 hours or more, seek immediate medical assistance. This situation could necessitate urgent care to prevent irreversible harm to your penis.
Should you notice a sudden loss of vision in one or both eyes, reach out to your doctor without delay. Immediate medical intervention could be critical.
Be sure to consult your healthcare provider promptly if you notice any sudden changes in hearing, including a decrease in hearing or complete loss of hearing, especially if accompanied by symptoms such as dizziness or ringing in the ears.
If you are undergoing treatment for high blood pressure, be cautious, as sildenafil may cause your blood pressure to drop significantly. If you experience blurred vision, confusion, dizziness, faintness, or lightheadedness upon standing up after lying down or sitting, sweating, or any unusual feeling of weakness or fatigue, contact your doctor right away.
It’s important to understand that this medication does not offer protection against sexually transmitted infections, including HIV or AIDS. Always practice safe sex, and discuss with your healthcare provider if you have any questions about protective measures.
Finally, avoid taking any additional medications unless they have been reviewed and approved by your doctor. This includes both prescription and over-the-counter medicines, as well as any herbal or vitamin supplements. Being open about all medications you are taking can help prevent potential interactions and ensure your safety.
