Loose stools can happen with big doses or gritty mixing; many people avoid it by splitting servings and taking it with food.

Hives after creatine can happen, often tied to additives or another trigger; stop it and get urgent care if you wheeze or swell.

A rash after starting creatine is uncommon; it’s more often tied to additives, dehydration, or a new product rather than creatine itself.

Early scale bumps often come from water pulled into muscle, not puffiness under skin, and many women see it level off in 1–3 weeks.

Creatine can nudge scale weight up early by pulling extra water into muscle, not by adding body fat, and the shift may settle with steady use.

Standard creatine doses haven’t been shown to harm healthy kidneys, but they can raise blood creatinine on lab tests.

In healthy adults, creatine monohydrate hasn’t been shown to trigger kidney failure at standard doses, though it can shift creatinine lab results.

Creatine can raise body water, mostly inside muscle, so the scale may climb early even when you don’t look “puffy.”

Most research doesn’t link creatine to balding, yet one small trial saw a DHT rise after a loading phase.

Creatine and finasteride can usually be taken on the same day, since they act on different systems and no direct interaction is listed on drug labeling.
