How does Spedra work?

Spedra contains an active substance called avanafil, which works in the same way as other popular erectile dysfunction drugs. It relaxes the blood vessels in your penis, allowing the blood flow to your penis to increase. This makes it easier to achieve and maintain an erection following sexual stimulation and during sex. Spedra treats the symptoms of erectile dysfunction but not the cause, so you may find you need to take it every time you have sex if the underlying reasons for your ED are not cured. Spedra is only for men over 18, and should not be taken by women.

How is Spedra taken?

Spedra should be swallowed with a glass of water at least half an hour before sex, as it may take up to thirty minutes to begin working. You can take Spedra with food, but if you eat a heavy meal or one that contains a lot of fat, this will mean Spedra will take longer to break down in your stomach and consequently longer to begin working.

Spedra is available in tablets of 50mg, 100mg or 200mg. The usual dosage is 100mg, which can be adjusted by your doctor if you find it too strong or too weak. Do not attempt to increase the dosage on your own and do not take more than one Spedra tablet in a day. You should also try Spedra at the initial dosage up to three times before speaking to your doctor about increasing the dosage, as your nerves or anxiety may be affecting its effect.

What is the difference between Spedra and other erectile dysfunction drugs?

Spedra's active ingredient, avanafil, is very similar to the active ingredients in other ED medications, such as sildenafil in Viagra or tadalafil in Cialis. It is absorbed quickly in your body, and you should feel its effects within 30-45 minutes. Some patients have found it to work more quickly or more slowly; this will also depend on how relaxed you are and what, and how recently, you have eaten.

Is it safe to buy Spedra online?

Spedra is sold on a number of websites online, as are most erectile dysfunction medications nowadays. However, it's important to remember that Spedra, like all ED medications, is prescription-only and any site or person attempting to sell it to you without a prescription is doing so illegally, unlicensed and unmonitored. You may receive fake or unreliable medication from these sources, and are at risk of unwanted side effects, especially if Spedra or any of the ingredients in these medications is unsuitable for you to begin with.

If for whatever reason, you do not want to see a doctor face to face, the safest way to buy Spedra online is through a properly accredited online doctor service like Superdrug Online Doctor.

Spedra can cause side effects in some patients. If the likelihood of side effects or interaction with other drugs you are currently taking is too high, our doctors may not issue a prescription and you will receive a refund.
