Do not take BlueMed (sildenafil) if you:

• take any medicines called nitrates, often prescribed for chest pain, or guanylate cyclase stimulators like riociguat for pulmonary hypertension. Your blood pressure could drop to an unsafe level
• are allergic to sildenafil or any of its ingredients

Discuss your health with your doctor to ensure that you are healthy enough for sex. If you experience chest pain, dizziness, or nausea during sex, seek immediate medical help.

Sildenafil can cause serious side effects. Rarely reported side effects include:

• an erection that will not go away (priapism). If you have an erection that lasts more than 4 hours, get medical help right away. If it is not treated right away, priapism can permanently damage your penis
• sudden vision loss in one or both eyes. This can be a sign of a serious eye problem called non-arteritic anterior ischemic optic neuropathy (NAION). Stop taking sildenafil and call your healthcare provider right away if you have any sudden vision loss
• sudden hearing decrease or hearing loss. Some people may also have ringing in their ears (tinnitus) or dizziness. If you have these symptoms, stop taking sildenafil and contact a doctor right away

Before you take BlueMed, tell your healthcare provider if you:

• have or have had heart problems such as a heart attack, irregular heartbeat, angina, chest pain, narrowing of the aortic valve, or heart failure
• have had heart surgery within the last 6 months
• have pulmonary hypertension
• have had a stroke
• have low blood pressure, or high blood pressure that is not controlled
• have a deformed penis shape
• have had an erection that lasted more than 4 hours
• have problems with your blood cells such as sickle cell anemia, multiple myeloma, or leukemia
• have retinitis pigmentosa, a rare genetic (runs in families) eye disease
• have ever had severe vision loss, including NAION
• have bleeding problems
• have or have had stomach ulcers
• have liver problems
• have kidney problems or are having kidney dialysis, or have any other medical conditions

Sildenafil can cause small declines in your blood pressure that may cause dizziness, lightheadedness or even fainting in people sensitive to blood pressure changes. Be sure that you are well-hydrated and in a safe, controlled environment the first time that you take sildenafil.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Sildenafil may affect the way other medicines work, and other medicines may affect the way sildenafil works, causing side effects. Especially tell your healthcare provider if you take any of the following:

• medicines called nitrates
• guanylate cyclase stimulators such as riociguat
• alpha-blockers such as terazosin, tamsulosin, doxazosin, prazosin, alfuzosin, or silodosin (sometimes prescribed for prostate problems or high blood pressure). In some patients, using sildenafil with alpha-blockers can lead to a drop in blood pressure or to fainting
• HIV protease inhibitors, such as ritonavir, indinavir, saquinavir, or atazanavir
• some types of oral antifungal medicines, such as ketoconazole and itraconazole
• some types of antibiotics, such as clarithromycin, telithromycin, or erythromycin
• other medicines that treat high blood pressure
• other medicines or treatments for ED, unless your healthcare provider has specifically instructed you that you can take your new ED medication at the same time. Combining ED medications can increase the risk of side effects such as low blood pressure, dizziness, or prolonged erections and should only be done under medical supervision

Sildenafil is the same medicine found in some pulmonary arterial hypertension (PAH) treatments. It should not be used with other PAH treatments containing sildenafil or any other PDE5 inhibitor (such as tadalafil).
