The active ingredient, Tadalafil, works by relaxing blood vessels and increasing blood flow. This same vasodilation effect can also affect blood vessels in the head, which is why headache is one of the most commonly reported side effects.
In clinical use and reports, headache is considered a frequent but usually mild and temporary side effect. APCALIS ORAL JELLY often appears within a few hours after taking the medicine and disappears as the drug wears off. Studies and patient data show that it is one of the most common reactions alongside flushing and indigestion.
Other related symptoms like dizziness, facial flushing, or nasal congestion may also occur at the same time because they are linked to the same blood vessel relaxation effect.
Headaches are more likely if:
The dose is high
Alcohol is consumed
The person is dehydrated
There is sensitivity to blood pressure changes
In most cases, the headache is not dangerous. It can often be reduced by drinking water, resting, or using a simple pain reliever (if medically safe).
However, if the headache is severe, persistent, or accompanied by chest pain, vision changes, or fainting, medical attention is needed.
Yes, Apcalis Oral Jelly can cause headaches, but they are usually mild, short-lived, and related to its blood-flow–changing action.
