I've been experiencing frequent nightfall can I take this herbal tablet without a prescription?

Frequent nightfall on its own is usually a normal physiological occurrence rather than a disease needing treatment, though I understand it can feel worrying when it happens often. Herbal tablets like this one, built around ashwagandha and related ingredients, are generally available without a prescription and considered low risk for most healthy adults. Still, if it's causing you real distress or happening unusually often, it's worth talking to a doctor, since they can look into whether there's an underlying stress or hormonal factor worth addressing.
