Eli Lilly and Co. Inc. said Tuesday it has received more than $4.3 billion in sales of the drug Viagra in the U. S. The company also will launch a version of its popular erectile dysfunction drug called Levitra in the U. on Monday, which will be available for $13.99 for a 30-day supply.
Lilly's Levitra, the generic version of Viagra, is the most widely used drug in the United States, but it has been under fire for some patients because it contains sildenafil, the same active ingredient found in other older erectile dysfunction drugs. Some users reported side effects such as headaches and dizziness.
"The company is committed to continuing to advance Levitra and will continue to work closely with its users to ensure that it is a safe and effective alternative for their erectile dysfunction," said Matthew McPherson, Lilly's medical affairs chief. "This new launch of Levitra will further strengthen Lilly's position as the leading supplier to Viagra, and will help establish a positive environment for patient satisfaction."
Patients will be able to use Levitra by the time the drug is available for U. delivery on Feb. 2.
"We are excited to announce that we have received more than $4.3 billion in sales of the Viagra product in the U. S.," said Paul Clark, Lilly's medical affairs chief. "We believe this launch of Levitra will further strengthen Lilly's position as the leading supplier of Viagra and will help establish a positive environment for patient satisfaction."
"This new launch of Viagra will further strengthen Lilly's position as the leading supplier of Viagra," Clark said. "We believe this new launch of Levitra will help establish a positive environment for patient satisfaction and help improve the overall quality of life for patients with erectile dysfunction."

"This launch of Levitra, the Pfizer-approved version of Viagra, will help ensure that patients with erectile dysfunction are treated with the appropriate medication that is proven safe and effective to treat their condition."

Viagra has been shown to cause some mild side effects. Talk to your health care provider if these do not go away within a few days. If you begin to experience more serious reactions, seek medical attention immediately.
Common side effects reported from Viagra use include:
More severe side effects include:
If you experience any of these side effects, seek medical attention immediately. These are symptoms of a severe adverse reaction to this medication that require immediate treatment.
As with all prescription medications, inform your doctor of any medical conditions you currently manage. Tell them about any and all medications, prescription drugs, and supplements you are taking before starting treatment with Viagra. Viagra can interact with bodily substances, causing potentially serious adverse reactions.
Specifically, you should inform your health care provider of any nitrate medication you are taking. Remember to mention any herbal products you use, especially St. John’s wort.
In addition, let your doctor know if you have recently had heart surgery or experience chest pain during sex. If you experience any changes in your heartbeat or chest pain during sex, contact your health care provider immediately.
asthma is a safe medication to take with Viagra - -Viagra can cause a dangerous low in blood pressure. Viagra can also interact with other medications, including certain antifungals, like ketoconazole, and ritonavir.
In addition, tell your doctor if you have had a history of fultaneor vision changes such as retinitis pigmentosa, cataracts, or laser therapy for cataract surgery. This is a rare condition that can cause permanent damage to one or both eyes. If you experience this, call your doctor immediately or get medical attention if you experience this.
diarrheaIf you experience any of the following side effects, contact your doctor immediately:
1.Nitrates (e.g., nitroglycerin, isosorbide dinitrate): Cialis and nitrates both lower blood pressure. Taking them together can cause a significant and potentially life-threatening drop in blood pressure (hypotension), leading to dizziness, fainting, or even heart attack or stroke. It is contraindicated to use Cialis with nitrates or recreational "poppers" (amyl nitrites).
2.Alpha-blockers (e.g., prazosin, terazosin, tamsulosin): Both Cialis and alpha-blockers relax blood vessels, which can lead to excessive blood pressure reduction when used together. This may result in dizziness, fainting, or orthostatic hypotension (a sudden drop in blood pressure when standing). If needed, your doctor may adjust the dosage or recommend spacing the medications.
3.Other antihypertensive drugs (e.g., atenolol, propranolol, enalapril, lisinopril): Cialis can enhance the blood-pressure-lowering effects of these medications. While this interaction is usually less severe than with nitrates or alpha-blockers, it can still cause dizziness or fainting in sensitive individuals. Close monitoring of blood pressure is recommended.
Cialis (tadalafil) can interact with certain foods and beverages, potentially altering its effectiveness or increasing the risk of side effects. Here are the key drug-food interactions to be aware of:
: Cialis is part of a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. It works by relaxing blood vessels, thereby increasing blood flow to the penis. It may therefore enhance the blood pressure-lowering effects of these medications.

Taking them together can cause a significant and potentially life-threatening drop in blood pressure (hypotension), leading to dizziness, fainting, or even heart attack or stroke. It is contraindicated to use Cialis with nitrates or recreational "poppers" (amyl nitrites).
