A few days after a local pharmacist asked a local woman to buy a ‘healthy’ erectile dysfunction medicine, she was quoted saying “the best medicine is viagra.”
“Viagra has made me feel so much better,” wrote the woman.
“But my blood pressure has dropped to 100/90. I am a very healthy woman.”
The woman is now taking her tokyo sachets with a gel called a viagra gel. The medicine contains the same ingredient as the prescription-strength Viagra, but is made from the same natural ingredients.
Sildenafil is the same active ingredient as the blue pill. It is available from many supermarkets, but has been available over the counter for years and has a black-and-white box telling you exactly what you can buy.
She says she doesn’t like to drink alcohol, but is completely unaware that she’s taking the pills.
It is illegal to buy the same medicine with a prescription, but you can buy Viagra with a prescription from a doctor, pharmacist or even some online pharmacies.
“There are a few things I have learned from a lot of pharmacies,” she said. “I am very, very careful not to drink too much, and I am not a diabetic.”
The woman says she does not think the men in her neighbourhood can take her tokyo sachets. It’s illegal to sell or distribute any herbal and natural supplements, which are not safe to buy without a doctor’s prescription.
“It’s so easy for them to take it, so easily. I’m not sure if it’s legal to buy it from a pharmacy or not.”
The woman said she was a ‘healthy’ woman and felt so much better after taking the pills.
The pharmacist told her that the pills had changed, and that her husband was now taking her tokyo sachets. “I thought they were supposed to make my wife feel better but they are not,” she said.
The woman said she had no idea they were so similar.
“I was shocked when they told me they would take it,” she said.
She said she is also worried about the high cost of the pills, which cost about $5 a tablet. “I have no idea how much it cost,” she said.
The woman wrote that she bought the pills for $5 a pack of four, and was able to buy them at a local pharmacy without a prescription.
She says she bought them from a local pharmacy, but was told they had a small quantity of the generic medication.
She says she did not want to be reminded of how much she costs and said she has also bought a box of the herbal and natural supplements, and is worried about the quality of the pills.
She says she takes the pills daily and it has made her feel so much better.
She says the pills are so cheap and easy to take that they should be on the shelves at some supermarkets.
She said she has to ask for prescriptions to be put in her order. She said she had no idea they were so similar.
“I’m not an ordinary man,” she said.
“My husband and I have never had any problems when we have a problem. It is not true.”
She says she is also worried about the high cost of the pills.
“I have been taking it for almost four years. I bought the pills from a local pharmacy and have been getting them for about $25 a pack. I would say I have to have a prescription,” she wrote.
She said it would be important to check with her GP, or other health professional who will prescribe the medication.
“I do not want to be seen by a doctor because it can be harmful to your health. I have not seen anyone mention the use of Viagra,” she wrote.
She said she can take the pills if they are taken on a daily basis and no other times.
The woman’s husband is a nurse and she has not yet spoken to her. She said it was just too late to be taking the pills for the same reason.
She said he is still in hospital and can no longer be seen by a doctor.
