What is Viagra?

It is not possible to determine whether these reported events are related directly to the use of VIAGRA, to the patient's underlying risk factors for hearing loss, a combination of these factors, or to other factors (see PRECAUTIONS, Information for Patients ). Other events reported post-marketing to have been observed in temporal association with VIAGRA and not listed in the clinical trial adverse reactions section above include: Nervous: seizure, seizure recurrence, anxiety, and transient global amnesia. Urogenital: prolonged erection, priapism (see WARNINGS ), and hematuria. Special Senses: diplopia, temporary vision loss/decreased vision, ocular redness or bloodshot appearance, ocular burning, ocular swelling/pressure, increased intraocular pressure, retinal vascular disease or bleeding, vitreous detachment/traction, paramacular edema and epistaxis. Non-arteritic anterior ischemic optic neuropathy (NAION), a cause of decreased vision including permanent loss of vision, has been reported rarely post-marketing in temporal association with the use of phosphodiesterase type 5 (PDE5) inhibitors, including VIAGRA.

More common

Most, but not all, of these patients had underlying anatomic or vascular risk factors for developing NAION, including but not necessarily limited to: low cup to disc ratio ("crowded disc"), age over 50, diabetes, hypertension, coronary artery disease, hyperlipidemia and smoking. It is not possible to determine whether these events are related directly to the use of PDE5 inhibitors, to the patient's underlying vascular risk factors or anatomical defects, to a combination of these factors, or to other factors (see PRECAUTIONS/Information for Patients ). In studies with healthy volunteers of single doses up to 800 mg, adverse events were similar to those seen at lower doses but incidence rates and severities were increased. In cases of overdose, standard supportive measures should be adopted as required. Renal dialysis is not expected to accelerate clearance as sildenafil is highly bound to plasma proteins and it is not eliminated in the urine. If you take any medicines that contain nitrates – either regularly or cheap viagra with dapoxetine as needed – you should never take VIAGRA. If you take VIAGRA with any nitrate medicine or recreational drug containing nitrates, your blood pressure could suddenly drop to an unsafe level. You could get dizzy, faint, or even have a heart attack or stroke.

Nitrates are found in many prescription medicines that are used to treat angina (chest pain due to heart disease) such as: nitroglycerin (sprays, ointments, skin patches or pastes, and tablets that are swallowed or dissolved in the mouth) isosorbide mononitrate and isosorbide dinitrate (tablets that are swallowed, chewed, or dissolved in the mouth) Nitrates are also found in recreational drugs such as amyl nitrate or nitrite ("poppers"). If you are not sure if any of your medicines contain nitrates, or if you do not understand what nitrates are, ask your doctor or pharmacist. VIAGRA is only for patients with erectile dysfunction. VIAGRA is not for newborns, children, or women. Do not let anyone else take your VIAGRA.

VIAGRA must be used only under a doctor's supervision. It is a treatment for erectile dysfunction.

How is Viagra used?

Before you start any treatment for erectile dysfunction, ask your doctor if your heart is healthy enough to handle the extra strain of having sex. If you have chest pains, dizziness or nausea during sex, stop having sex and immediately tell your doctor you have had this problem. VIAGRA enables many men with erectile dysfunction to respond to sexual stimulation. When a man is sexually excited, VIAGRA helps the penis fill with enough blood to cause an erection. After sex is over, the erection goes away. VIAGRA does not protect you or your partner from getting sexually transmitted diseases, including HIV—the virus that causes AIDS. • WHAT TO TELL YOUR DOCTOR BEFORE YOU BEGIN VIAGRA Only your doctor can decide if VIAGRA is right for you. VIAGRA can cause mild, temporary lowering of your blood pressure. You will need to have a thorough medical exam to diagnose your erectile dysfunction and to find out if you can safely take VIAGRA alone or with your other medicines. Your doctor should determine if your heart is healthy enough to handle the extra strain of having sex. Be sure to tell your doctor if you: have ever had any heart problems (e.g., angina, chest pain, heart failure, irregular heart beats, heart attack or narrowing of the aortic valve) have a rare inherited eye disease called retinitis pigmentosa have ever had any blood problems, including sickle cell anemia or leukemia are allergic to sildenafil or any of the other ingredients of VIAGRA tablets have a deformed penis, Peyronie's disease, or ever had an erection that lasted more than 4 hours have stomach ulcers or any types of bleeding problems Some medicines can change the way VIAGRA works.

  • Generic versions of 25 mg Viagra are available and usually cheaper.
  • Always purchase Viagra from reputable pharmacies to avoid counterfeit products.
  • Combining Viagra with other ED medications is not recommended.
  • Be aware of potential interactions if taking other prescription drugs.
  • The efficacy of 25 mg Viagra can vary based on individual health factors.
  • Use Viagra only as directed by a healthcare provider.
  • Do not take Viagra if you have been advised against sexual activity for health reasons.

Tell your doctor about any medicines you are taking. Do not start or stop taking any medicines before checking with your doctor or pharmacist.

How to take Viagra 100mg tablets?

For most patients, the recommended dose is 50 mg taken, as needed, approximately 1 hour before sexual activity. However, VIAGRA may be taken anywhere from 4 hours to 0.5 hour before sexual activity. Based on effectiveness and toleration, the dose may be increased to a maximum recommended dose of 100 mg or decreased to 25 mg. The maximum recommended dosing frequency is once per day. The following factors are associated with increased plasma levels of sildenafil: age greater than 65 (40% increase in AUC), hepatic impairment (e.g., cirrhosis, 80%), severe renal impairment (creatinine clearance less than 30 mL/min, 100%), and concomitant use of potent cytochrome P450 3A4 inhibitors [ketoconazole, itraconazole, erythromycin (182%), saquinavir (210%)].

Less common

Since higher plasma levels may increase both the efficacy and incidence of adverse events, a starting dose of 25 mg should be considered in these patients. Ritonavir greatly increased the systemic level of sildenafil in a study of healthy, non-HIV infected volunteers (11-fold increase in AUC, see Drug Interactions .) Based on these pharmacokinetic data, it is recommended not to exceed a maximum single dose of 25 mg of VIAGRA in a 48 hour period. VIAGRA was shown to potentiate the hypotensive effects of nitrates and its administration in patients who use nitric oxide donors or nitrates in any form is therefore contraindicated. When VIAGRA is co-administered with an alpha-blocker, patients should be stable on alpha-blocker therapy prior to initiating VIAGRA treatment and VIAGRA should be initiated at the lowest dose (see Drug Interactions ). VIAGRA (sildenafil citrate) is supplied as blue, film-coated, rounded-diamond-shaped tablets containing sildenafil citrate equivalent to the nominally indicated amount of sildenafil as follows: Store at 25°C (77°F); excursions permitted to 15–30°C (59–86°F) [see USP Controlled Room Temperature]. This includes prescription and nonprescription medicines or remedies: Remember, VIAGRA should never be used with medicines that contain nitrates (see VIAGRA Is Not for Everyone). If you are taking medicines called alpha-blockers for the treatment of high blood pressure or prostate problems, your blood pressure could suddenly drop.

Who is Viagra suitable for?

Phonetic Name

It is intended for use only by men who have a condition called erectile dysfunction. VIAGRA must never be used by men who are taking medicines that contain nitrates of any kind, at any time. If you take VIAGRA with any nitrate medicine your blood pressure could suddenly drop to an unsafe or life threatening level. VIAGRA is a pill used to treat erectile dysfunction (impotence) in men. It can help many men who have erectile dysfunction get and keep an erection when they become sexually excited (stimulated). If you are taking a protease inhibitor, your dose may be adjusted (please see Finding the Right Dose for You). VIAGRA should not be used with any other medical treatments that cause erections. These treatments include pills, medicines that are injected or inserted into the penis, implants or vacuum pumps. VIAGRA contains sildenafil, which is the same medicine found in another drug called REVATIO. REVATIO is used to treat a rare disease called pulmonary arterial hypertension. VIAGRA should not be used with REVATIO. VIAGRA comes in different doses (25 mg, 50 mg and 100 mg). If you do not get the results you expect, talk with your doctor. You and your doctor can determine the dose that works best for you.

Population Group Effectiveness (%) Notes
Men with ED 70–80% Effective in most cases when taken as directed
Men on certain medications 60–75% Slightly reduced effectiveness due to interactions
Older adults 65–80% Slightly lower due to metabolic changes

If you think you need a larger dose of VIAGRA, check with your doctor.

Why has Viagra been approved?

You will not get an erection just by taking this medicine. VIAGRA helps a man with erectile dysfunction get an erection only when he is sexually excited. When a man is sexually excited, the penis rapidly fills with more blood than usual. After the man is done having sex, this extra blood flows out of the penis back into the body. If an erection lasts for a long time (more than 6 hours), it can permanently damage your penis.

Give yourself time for it to work

You should call a doctor immediately if you ever have a prolonged erection that lasts more than 4 hours. Some conditions and medicines interfere with this natural erection process. The penis cannot fill with enough blood. This is called erectile dysfunction if it becomes a frequent problem. Therefore sexual activity may not be advisable for people who have heart problems. VIAGRA should not be taken more than once a day. Your doctor may prescribe a lower dose of VIAGRA in certain circumstances.

Step Instructions Tips
1 Take tablet with water, on an empty stomach or after a light meal Avoid high-fat foods immediately prior to taking
2 Do not take more than one dose in 24 hours Follow doctor's prescription
3 Avoid alcohol and heavy meals close to intake Can impair effectiveness
