Viagra is used to treat problems related to male sexual function, especially problems regarding the ability to achieve and maintain an erection. Learn how to take Viagra safely to treat erectile dysfunction.
Step
Method 1 of 3: Determine whether or not to take Viagra
Step 1. Consult a doctor
You may be advised to take Viagra (sildenafil) if you have erectile dysfunction, or an inability to maintain an erection long enough to engage in sexual activity. It is very important to discuss the treatment with your doctor to make sure that it is a healthy choice for you.
- Tell your doctor if you are allergic to any medicines, so he or she can determine whether you are allergic to Viagra or not.
- Tell your doctor any other medications you are taking, including herbal supplements.
Step 2. Do not take Viagra if you are taking nitrates
Nitroglycerin and other long-acting nitrates used to treat chest pain are contraindicated with Viagra, which can cause blood pressure to drop to dangerous levels and lead to a heart attack or stroke.
Step 3. Do not take Viagra if you are taking an alpha-blocker
This drug, which is prescribed for blood pressure and prostate problems, can also cause blood pressure to drop to too low a level if it is mixed with Viagra.
Method 2 of 3: Taking Viagra to Improve Sexual Function
Step 1. Swallow Viagra pills as directed by your doctor or pharmacist
The usual recommended dose is 50 mg, but in some cases your doctor may recommend taking more or less than the average dose.
- Viagra pills are available in 25 mg, 50 mg, or 100 mg tablets.
- The maximum recommended dose is 100 mg. Do not take more than this dose at once.
Step 2. Take Viagra 30 to 60 minutes before having sex
Viagra is most effective when taken during this time, as it takes less time to circulate and stimulate an erection. However, Viagra can be taken up to 4 hours before sexual activity and still be effective.
Step 3. Do not take Viagra more than once a day
Taking Viagra several times a day is not recommended, especially if the consumption exceeds the recommended 100 mg dose.
Step 4. Eat a low-fat diet before you take Viagra
Eating foods that are high in fat can slow down the effects of Viagra. Eat light meals throughout the day before taking Viagra, and avoid heavy meals that contain red meat, fried foods, and other components that are high in fat.
Method 3 of 3: Watching for Side Effects
Step 1. Be aware of moderate side effects
Some people experience moderate levels of side effects after taking a single dose of Viagra. This doesn't mean you need to see a doctor, but if you do, you should either lower your dose or stop using Viagra. Moderate side effects of Viagra include:
- Redness and burning sensation in the neck and face
- Headache
- Nasal congestion
- Memory problem
- Stomachache or backache
Step 2. Go to the doctor immediately if you experience severe side effects
In some rare cases, Viagra causes side effects that are quite dangerous which must be taken to the doctor immediately. If you experience any of the following symptoms, stop taking Viagra immediately and call your doctor:
- Erections that are painful or last 4 hours or longer
- Loss of sight
- Chest pain
- Irregular heartbeat
- Feeling dizzy
- Swelling in the hands, ankles or feet
- Nausea or general ill feeling
