Sildenafil (oral route)

It is crucial that you inform all of your healthcare providers that you are taking sildenafil. If you find yourself needing urgent medical assistance due to a heart condition, it is vital that your doctor is aware of the last time you ingested sildenafil. This information can significantly affect the care you receive in an emergency situation.

Avoid using this medication in conjunction with any nitrate drugs, which are typically prescribed for the treatment of angina or to help manage high blood pressure. Nitrate medications consist of nitroglycerin, isosorbide, Imdur®, Nitro-Bid®, Nitro-Dur®, Nitrol® ointment, Nitrostat®, and Transderm Nitro®. Furthermore, be cautious of illegal substances often referred to as "poppers," such as amyl nitrate, butyl nitrate, or nitrite. It is also imperative not to use sildenafil in conjunction with riociguat (Adempas®), as dangerous interactions can occur.

If your physician has prescribed this medication for pulmonary arterial hypertension, they will likely want to monitor your progress through routine check-ups. These appointments will enable your healthcare provider to verify that the medication is effective and to determine if you should continue its use. Regular evaluations are essential to ensure the best possible health outcomes.

For patients taking sildenafil specifically for pulmonary arterial hypertension, it is critical to avoid taking Viagra® or any other PDE5 inhibitors, such as tadalafil (Cialis®) or vardenafil (Levitra®), as this can escalate the risk of adverse reactions. Remember that Viagra® also contains sildenafil, and combining medications can increase the likelihood of side effects.

Sildenafil should not be used alongside any other treatments or devices aimed at inducing erections. The concurrent use of such products can lead to unforeseen complications.

It is equally important to inform your doctor about any existing heart conditions or any heart issues you may have had in the past. This medication can lead to severe side effects for individuals with a history of heart problems.

Should you experience an erection that lasts for 4 hours or more and is painful, you must contact your healthcare provider immediately. This situation may require urgent medical intervention to avoid serious, lasting damage to your penis, highlighting the need for prompt action.

If a sudden loss of vision occurs in one or both of your eyes, seek immediate medical advice. This is a serious concern and demands prompt attention.

Also, be alert for a sudden decrease in hearing or complete hearing loss, particularly if accompanied by dizziness or a ringing sensation in the ears. This could indicate a serious side effect that requires immediate evaluation by a healthcare professional.

For those already on medication for high blood pressure (hypertension), sildenafil may lower your blood pressure to unsafe levels. If you experience symptoms such as blurred vision, confusion, dizziness, faintness, or lightheadedness when changing positions quickly, along with excessive sweating or unusual fatigue, contact your doctor without delay.

This medication does not provide any protection against sexually transmitted infections (including HIV or AIDS). It is advisable to practice safe sex and consult your healthcare provider with any questions or concerns regarding protection.

Lastly, refrain from starting any new medications before discussing them with your healthcare provider. This includes both prescription and over-the-counter (OTC) drugs, as well as any herbal or vitamin supplements. Uninformed use of other medications may lead to serious drug interactions.
