How Long Does It Take For Viagra To Start Working?

default
Posted on Tue, 24 Jan 2017
Question: I had a prescription for Viagra (50 mg.) but it had little effect. My Dr. approved my increasing to 100 mg. and that works pretty good, but is terribly expensive at more than $100 per 100 mg. dose. The Dr. has now given me a prescription for 10 mg. tablets of Cialis, cautioning me to NOT double up that dosage as I did with the Viagra. I understand that Cialis lasts longer than the few hours that Viagra remained effective, but how should I space out the 10 mg. dosage of Cialis? No closer than once every 2 days, every 3 days, or what? Also, I took the Viagra an hour and a half to two hours before having sex. How far in advance of the sexual activity should I take the Cialis? (BTW - I am 79 years old and will turn 80 in May - still loving sex and having it as often as possible.)

Brief Answer:
Once in 4 days, best if taken 1-2 hours prior to intercourse

Detailed Answer:
Hello sir and welcome.

Thank you for writing to us.

I have gone through your query with diligence and would like you to know that I am here to help. I am happy to learn about your active sex life, and you should know that it is a sign of good health, so I am really happy. Here are response to each of your asked queries sir:

+Cialis should best be taken about 1-2 hours prior to sex, but in case of impromptu events (more common and fun with sexual intercourse), the drug should be taken at least 30 minutes prior to intercourse

+I think if you are on a 10 mg dose, it would be best to take the pill at least once in 4 days, the effect should last on a 2.5 mg per day dose (just for better understanding).

I hope you find my response both helpful and informative. Please feel free to write back to me for any further clarifications, I am always here to help.

Best wishes.

Thank you for your prompt response. I am subject to "rather impromptu sexual events" since I do not have a spouse and must rely on occasional "friends" who are willing to help me remain "happy".

I do have a question just to clarify your answer to my question regarding the frequency/closeness of doses. You say above -"It would be best to take the pill at least once in 4 days, the effect should last on a 2.5 mg per day dose (just for better understanding)." Are you saying that the 10 mg dos is actually a "time release" dos of approximately 2.5 mg per day, or do you mean that I should take a 2.5 mg dose each day and the 10 mg dos every 4 days?

OR

Do you mean that I may take the 10 mg. dose sooner than every 4th day? I notice that you said "at least once in 4 days".

Brief Answer:
Do not take 10 mg of cialis more than once every 4 days :)

Detailed Answer:
Hello once again.

Sorry for not being clear enough, what I meant was that if you do take 10 mg of Cialis, the medication's effect should last for about 4 days, which breaks it down to around 2.5 mg being used each day. This was just for a break up, and I was not asking you to take 2.5 mg per day.

If you take 10 mg of cialis, you should feel its effect last for about 4 days. So it would be best to take the next dose, not earlier than 4 days from the last dose.

No, what I meant was that the 10 mg of cialis is to be taken not more than once every 4 days.

I hope this makes things more clear, I wish you loads of luck and please also remember to be safe, as you mentioned you have had to rely on friends to make you happy. Being healthy and sexually active is great, but being safe is much more important.

God speed :)
