I am not a medical professional, and I've massaged medical details in the story to better fit the themes. Take medical advice only from qualified personnel or their official information dispensers like special websites or manuals with the medicine. Never from an erotic stories site, social media post, or random strangers on the internet.
Otherwise just a light erotic story.

Rob looked at his GP in disbelief. "You can't be serious."
"It is my job to be serious," she said, all professionalism. "There is a long list of side effects. I assume you've heard the big one-," there was the slightest pause of significance. "-and you're probably familiar what you need to do when that side effect takes too long. These aren't the only thing to watch out for. It is a heart medicine. You need to read the leaflet with the warnings
carefully.
This is not a toy."
"That goes against everything I heard about the medicine," Rob muttered.
There was a flash in her demeanour. Together with her overt professionalism he suddenly realised what was going on.
"Sarah, I've known you now for twenty years or so. That's nearly all of my life. I'd like to think I know you, even if our meetings are infrequent. Tell me honestly. You're enjoying this, aren't you?"
A mischievous grin escaped her. "I'm sorry Robert. Since I found out yesterday it's all I've thought about. Frankly, it's the first time I've ever prescribed it." She took a serious face again. It lasted only a moment. "First time for a heart condition anyway," she couldn't stop smiling.
Sarah rummaged in her drawer. "Here. These are a first batch for you. The rest will be on prescription via the apothecary. As you look like you sport a lot, I thought it would be better to give them early." The box was shoved carefully towards him.
The contents were exactly as he expected. A stiff plastic wrapper holding each blue pill. Twelve per wrapper. Three wrappers in a box. "Isn't that a lot of Viagra?" Rob asked dubiously.
"I think so too, but they can go fast. Please read the leaflet. There's a lot of warnings. It is still a heart medicine. Take them before each strenuous activity."
"I know one strenuous activity that it comes in handy," Rob said with a weak smile.
Sarah returned it. "Yes even that one. You're 25. I assume you're still going hard and heavy. At my age you go often much slower."
Rob packed the pills in his bag. "That's the first time you've shared something that intimate," he observed.
"I thought sharing would get your mind of things. Even though I can't stop smiling about it, I want you to know I understand it must be difficult."
"Thanks Sarah. We'll, I guess I'll go home now."
"One more thing," Sarah said as he was about to exit the door.
"Yes?"
"Even though your future is a bit darker, do not forget to have fun. The pill can help."
Rob nodded, contemplating what he would do at home.

"I think we shouldn't go sporting together tomorrow," Rob told his sport buddy.
"Why not? Do you have a date?" Samantha asked.
"Do you remember that time I felt ill during sports? They know what it is. A mild case of pulmonary arterial hypertension. The abbreviation is PAH. That's how I feel too. PAH." Rob tested the word out, feeling the resentments it had for his life.
"It's just high blood pressure of the arteries and the lungs?" Samantha liked to show off her studies of medicine.
"That's the one. They think that all the sports I do increased the blood pressure. It is very rare at my age. If I exert myself I can break things in my lungs or my coronal artery."
"It sounds bad, but that's easily treatable though. You told me a week ago you had drugs for it? What's changed?"
"I did, and they helped. That is until I got an allergic reaction. Apparently I'm allergic to nitro-glycerine. I thought everyone would be, if you shake hard enough," Rob said with sadness.
"At least you had a good opening line for the girls. Something about your heart exploding from your chest. I'm sure there's usable material. So, what do you have now?"
Rob showed his arm, the remnants of yesterday still visible. "There's only one that I'm not allergic to. Sildenafil." He pointed at one empty space on his arm, sandwiched between many angry lines of the allergy test, already fading into oblivion.
"Sildenafil?" After a moment Samantha's eyes became wide. "Viagra?! You need to take Viagra before each work out?"
"You're too excited about that. It's only a mild case, so in general I can still do things that don't get my heart above 130 or so. So we can still do strength days together, if I don't go for my usual weights."
"Who is saying that I'm too excited?!"
"Your smile, if not the volume of your voice. You're as bad as my GP."
"Sorry," she muttered. Her grin told she wasn't very sorry. "Can I see? It's been a while since I've seen one."
"You've seen them before?" Rib asked curiously. He presented the offending box.
"I do have a sex life, get over it," she said as she opened the box. "Oh. They never really change them, do they? Have you used one yet?"
"Not really. I thought tomorrow I can try with some light workout."
