Sildenafil (oral route)
It is crucial to inform all of your healthcare providers that you are taking sildenafil. In situations where you may require emergency medical treatment due to a heart condition, your healthcare provider must be informed about the last time you consumed sildenafil to avoid complications or interactions.
Avoid using this medication in conjunction with any nitrate therapies, which are commonly prescribed for chest pain (angina) or to manage high blood pressure. Nitrate products include a variety of medications such as nitroglycerin, isosorbide, Imdur®, Nitro-Bid®, Nitro-Dur®, as well as topical formulations like Nitrol® ointment, Nitrolingual® spray, Nitrostat®, and Transderm Nitro®. Additionally, illegal substances referred to as “poppers” that contain amyl nitrate or butyl nitrate should also be avoided. Furthermore, using sildenafil while on riociguat (Adempas®) can be dangerous and should not occur.
When utilizing sildenafil for the treatment of pulmonary arterial hypertension, it is essential that your physician conducts regular follow-up visits. These check-ups are vital to monitor your response to the medication, ensuring it is effective and determining whether it is safe for you to continue its use.
If you are prescribed sildenafil for pulmonary arterial hypertension, refrain from using Viagra® or any alternative PDE5 inhibitors such as tadalafil (Cialis®) or vardenafil (Levitra®). Remember that Viagra® contains sildenafil, and combining these medications can significantly increase the risk of adverse side effects.
Sildenafil should also not be combined with any other treatments or devices intended to induce erections.
It is imperative to disclose any existing or prior cardiovascular issues to your doctor. Sildenafil can pose serious risks for individuals with heart complications, therefore thorough communication regarding your medical history is essential.
Should you experience an erection lasting longer than 4 hours, or if it becomes painful, seek medical attention without delay. This condition, known as priapism, can lead to irreversible damage if not treated promptly.
If you notice a sudden change in vision or abrupt loss of sight in one or both eyes, it is vital to reach out to your doctor immediately. This could indicate a serious reaction to the medication.
Should you experience any sudden decline in your hearing, which may be accompanied by sensations of dizziness or ringing in your ears, consult your healthcare provider instantly. These symptoms could signify a serious side effect associated with sildenafil.
If you are already under treatment for high blood pressure (hypertension), be cautious as sildenafil may cause an excessive drop in your blood pressure levels. Contact your healthcare practitioner immediately if you experience symptoms like blurred vision, confusion, dizziness, or faintness when standing up suddenly, alongside excessive sweating or unexpected fatigue.
It is essential to understand that this medication does not provide protection against sexually transmitted infections (including HIV or AIDS). Implement protective measures and consult with your healthcare provider if you have any inquiries regarding this matter.
Do not initiate any other medications without first discussing it with your healthcare provider. This includes both prescription and over-the-counter (OTC) medications, as well as any herbal supplements or vitamins you may be considering.
