Headache, head pressure

Many people said taking an antihistamine right after ejaculation clearly eased symptoms such as headache, weakness and allergy-like inflammation; one person put it at 40–90% less. Others said symptoms came back the next day, so they kept taking it for 4–5 days. Personal reports — talk to a doctor before using medication.

Four people said that drinking coffee, Red Bull or other caffeinated drinks during an episode gave temporary relief from symptoms such as headache and fatigue. One felt almost normal for about two hours before it wore off, and another stressed it only helps for a few hours and is no cure.

Two people said coffee or another caffeinated drink after symptoms start eased their headaches, brain fog and body aches and gave a bit of energy — but only for a while, and a stuffy nose stayed. Neither gave amounts or how often.

Two people said ibuprofen taken when symptoms hit gave some relief: one took 200 mg during a migraine aura, blind spot and headache and said their mind felt clear, brain fog dropped and their voice got stronger; the other said it helped a little with head heaviness. Personal reports — painkillers carry risks, so talk to a doctor first.

Two people mentioned niacin: one said taking it before and right after orgasm blocks the symptoms for them; the other used the niacin flush only rarely, fearing it might affect blood sugar. Hives were also noted. Personal reports — check with a doctor before taking supplements.

Two people listed omega-3 fish oil among the things that help them, and one said a daily fish and krill oil complex seems to help with headaches too. No dose was given. Personal reports — check with a doctor before taking supplements.

One person said they took 50 mg of hydroxyzine plus 60 mg of Sudafed before orgasm for about two weeks and found hydroxyzine the most helpful thing so far. The severe eye pain, headaches and weakness they used to get after orgasm had clearly improved. Personal report only — check with a doctor before using medication.

One person said ibuprofen helped with the headaches and body aches they get with POIS. They didn't say how much or when they took it. Personal report only — check with a doctor before using medication.

One person said niacin and CBD, which they described as vasodilators, relieve their POIS; when it hits they feel pressure in the forehead and can feel the vasodilating effect there too. Personal report only — check with a doctor before taking supplements.

One person drank a glass of water with 1/8 teaspoon of salt and 1/8 teaspoon of potassium chloride and said it eased their headache and brain fog within 10–20 minutes. Personal report only — check with a doctor before supplementing electrolytes.

One person said antihistamines helped them most with headache and a hot neck after POIS episodes, without naming the drug, dose or timing. Personal report — talk to a doctor before using medication.

One person said that after a few chiropractor adjustments of the neck and spine their symptoms were almost completely gone; they linked the symptoms to the vagus nerve. The number and spacing of sessions weren't given.

One person said a low-histamine diet helped them a lot and hoped it would bring someone else relief. They didn't say which foods they avoided or which symptoms improved.

One person said that taking Allegra (fexofenadine, an antihistamine) together with propranolol (a beta blocker) after POIS symptoms appeared seemed to reduce their symptoms significantly. No dose given. A single personal report — check with a doctor before using medication.

One person said they relapsed while on antihistamines yet felt good, better than in a long time, and when they tried it again it was still fine. The drug and dose weren't named. Personal report — talk to a doctor before using medication.

One person said straining during a bowel movement can set symptoms off too, not only sex. For them, relaxing and letting it come naturally was what worked.

One person said heat alone, even without ejaculating, strongly sets off their POIS — for example 90°F (about 32°C) or more outside and a while in it. They avoided high heat, used air conditioning and stayed out of hot cars.

One person said head pressure after ejaculation seemed to go away with CBD, though they weren't sure. No dose or exact timing was given.

One person said cold showers were much better than hot ones, with noticeably less brain fog and head pressure. No water temperature or length of shower was given.

One person tried several supplements and said curcumin with rosemary extract seemed to help a little, though it was no cure. No doses or duration were given. Personal report — check with a doctor before taking supplements.
