Administration Instructions
Tablets are taken orally with or without food. If using the oral suspension, shake well before each use to mix the medication evenly. Use the provided oral syringe to measure each dose.
Adverse Reactions and Side Effects
Common side effects of Sildenafil include headaches, flushing, upset stomach, abnormal vision, stuffy or runny nose, back pain, muscle pain, and nausea. Rare, but serious side effects include an erection that will not go away (priapism), sudden vision loss in one or both eyes, and sudden hearing decrease or loss. If you experience any of these, seek medical help immediately.
Contraindications
Contraindications are conditions or factors that serve as a reason to withhold a certain medical treatment due to the harm that it would cause the patient. Sildenafil is contraindicated in patients with:
- A known hypersensitivity to Sildenafil or any component of the tablet.
- Those using nitrate drugs for chest pain or heart problems. This combination can cause a sudden and serious decrease in blood pressure.
Drug to Drug Interactions
Sildenafil may interact with certain drugs, including:
- Nitroglycerin (Nitrostat, Nitrolingual, Nitro-Dur, Nitro-Bid, others)
- Isosorbide mononitrate and dinitrate (Monoket, Imdur, ISMO)
- Certain antifungals like Ketoconazole (Nizoral), Itraconazole (Sporanox)
Sildenafil in Pregnancy
There’s no adequate and well-controlled studies in pregnant women. Sildenafil should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Sildenafil while Breastfeeding
It’s not known if Sildenafil is excreted into breast milk. A decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Estimated Cost of Medication
As of this writing, the estimated cost of a 30-day supply of Sildenafil 50mg with a GoodRx coupon is around $15-$30 without insurance, though prices may vary based on location and pharmacy.
Possible Alternatives
For erectile dysfunction, lifestyle modifications such as weight loss and exercise, and psychological counseling may help. For pulmonary arterial hypertension, other medications like bosentan, ambrisentan, or treprostinil may be alternatives. For altitude sickness, descent and oxygen supplementation are first-line treatments. Always discuss these alternatives with your healthcare provider or our telemedicine team before making any changes.
